Description

COMPOSITIONS AND METHODS FOR MODULATING NITROGEN FIXATION IN BACTERIACROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Patent Application Serial No. 63 / 614,554 filed 23 December 2023, herein incorporated by reference in its entirety.REFERENCE TO SEQUENCE LISTING SUBMITTED ELECTRONICALLY

[0002] The official copy of the sequence listing is submitted electronically as a WIPO ST26 compliant XML sequence listing with a file named 23032_SeqListing.xml created on 21 November 2024 and having a size of 237,765 bytes and is filed concurrently with the specification. The sequence listing comprised in this document is part of the specification and is herein incorporated by reference in its entirety.FIELD

[0003] The present disclosure relates to isolated and genetically modified microorganisms that have application, inter alia, in agriculture. The disclosed microorganisms can be utilized in their isolated and biologically pure states, as well as being formulated into agriculturally acceptable compositions. Also disclosed are methods of using the isolated microorganisms or agriculturally acceptable compositions in agricultural applications.BACKGROUND

[0004] Scientists have estimated that if the global agricultural “yield gap” (which is the difference between the best observed yield and results elsewhere) could be closed, then worldwide crop production would rise by 45-70%. That is, if all farmers, regardless of worldwide location, could achieve the highest attainable yield expected for their respective regions, then a great majority of the deficiencies in worldwide food production could be addressed. However, solving the problem of how to achieve higher yields across a heterogenous worldwide landscape are difficult. Often, yield gaps can be explained by inadequate water, substandard farming practices, inadequate fertilizers, and the non-availability of herbicides and pesticides. However, to vastly increase the worldwide use of water, fertilizers, herbicides, and pesticides, would not only be economically infeasible for most of the world, but would have negative environmental consequences.

[0005] Thus, meeting global agricultural yield expectations, by simply scaling up current high- input agricultural systems — utilized in most of the developed world — is simply not feasible.

[0006] There is therefore an urgent need in the art for improved methods of increasing crop performance and imparting beneficial traits to desired plant species. The technology described herein includes modifying the intergenic regions in nitrogen fixation clusters, to alter the amount of atmospheric nitrogen that is fixed by bacteria.

[0007] Nitrogen is the most abundant gas in the earth’s atmosphere; however, Ni is not bioavailable for plants, which need nitrogen for proper growth and production. Synthetic nitrogen fertilizer in the form of ammonia or ammonium (Nth / NH ) is utilized extensively in agriculture, most commonly industrially-prepared via the Haber-Bosch process, which requires high energy input along with natural gas while producing greenhouses gases as byproduct.

[0008] Biological nitrogen fixation can occur in bacteria, which utilize the enzyme nitrogenase to convert N2 into bioavailable ammonia. Organisms expressing this enzyme complex may be able to reduce the reliance of modem agriculture on Haber-Bosch process and copious application of synthetic nitrogen fertilizer. Despite this possibility, methods of regulating the fixation of atmospheric nitrogen are limited to utilizing a bacterium’s native nitrogen fixation genes that have been thought to be under the control of a single regulatory element, thus limiting the modulation of nitrogen fixation to suit the needs of a particular application.SUMMARY

[0009] Described herein are modifications to polynucleotides upstream (5’) of nitrogen fixation genes, including nitrogen fixation gene clusters (“nif” clusters), in bacteria, to improve the function of bacteria, for example the capability of fixing nitrogen.

[0010] Included are microorganisms that have application in various fields, including agriculture. The disclosed microorganisms can be utilized in their isolated and biologically pure states, as well as being formulated into agriculturally acceptable compositions. Further provided are agriculturally beneficial microbial consortia, comprising at least two members of the disclosed microorganisms, as well as methods of utilizing said consortia in agricultural applications. In some aspects, genomic modification of the microbes (individual, consortia, and / or communities) are contemplated, for the improvement of microbial traits and the improvement of microbe-associated plants.

[0011] The present disclosure addresses the important issue of how to improve plant performance, thereby closing the worldwide yield gap, along with providing ways of imparting other beneficial traits to plant species. The modified strains described herein improve plant performance by enabling the plant for increased and / or improved nitrogen availability, fixation, uptake, acquisition, tolerance, distribution, regulation, processing, and / or any plurality and / or combination of any of the preceding.

[0012] In some embodiments, the plant is a non-leguminous crop plant. In some embodiments, the plant is a leguminous crop plant.

[0013] In some embodiments, the plant is a dicot.

[0014] In some embodiments, the plant is soybean, canola, or cotton.

[0015] In some embodiments, the plant is a vegetable, herb, ornamental, or fruit plant. In some embodiments, the plant is selected from the group consisting of: kale, spinach, lettuce, carrot, potato, beet, radish, tomato, broccoli, cauliflower, squash, mustard, berry, pepper, greens, pole beans, muskmelon, cucumber, basil, grape, and okra.

[0016] In some embodiments, the plant is a monocot. In some embodiments, the plant is a C3 monocot. In some embodiments, the plant is a C4 monocot. In some embodiments, the plant is selected from the group consisting of: maize, wheat, rice, sorghum, sugarcane, onion, bamboo, palm, garlic, ginger, lily, daffodil, iris, orchid, bluebell, tulip, amaryllis, banana, plantain, ginger, turmeric, cardamom, asparagus, pineapple, sedge, rush, leek, forage grass, turf grass, buckwheat, quinoa, chia, and millet.

[0017] The solution to increasing crop performance and increasing yield proffered by the present disclosure is not detrimental to the earth’s resources, as it does not rely upon increased water consumption or increased input of synthetic chemicals into a system. Rather, the present disclosure utilizes microbes to impart beneficial properties, including increased yields, to desirable plants.

[0018] The disclosure therefore offers an environmentally sustainable solution that allows farmers to increase yields of important crops, which is not reliant upon increased utilization of synthetic herbicides and pesticides.

[0019] In embodiments, the disclosure provides for an efficient and broadly applicable agricultural platform utilizing microbes and microbial consortia (a plurality of microbes, in someaspects a plurality that improves the health or desired phenotype of the plant, such as an agronomic trait, with which it is associated) that promote one or more desirable plant properties.

[0020] The microbes disclosed herein improve the performance of plants, such as crop plants, by both direct and indirect mechanisms. In some aspects, the microbe becomes symbiotic with the plant. In some aspects, the microbe produces a compound (e.g., a metabolite, a toxin, a protein, a lipopeptide, or other composition) that confers a benefit to the plant or that the plant can use for improved characteristics. In some aspects, the microbe improves the solubility of one or more compositions, such as a nutrient, thereby benefitting the plant. In some aspects, the microbe imparts a tolerance to the plant to an exogenous substance such as an herbicide or a pesticide. In some aspects, the microbe produces a composition that is detrimental to a plant pest, such as an insect. In some aspects, the microbe fixes Nitrogen, thereby improving the nutritional status of the plant. Other aspects beyond the exemplary non-limiting aspects listed above are contemplated.

[0021] In some embodiments, a single microbe is utilized. In some aspects, the single microbe is isolated and purified. In some aspects, the single microbe is a taxonomic species of bacteria. In some aspects, the single microbe is an identifiable strain of a taxonomic species of bacteria. In some aspects, the single microbe is a novel, newly discovered strain of a taxonomic species of bacteria.

[0022] In some aspects, the single microbe — whether a taxonomically identifiable species or strain — is combined with one or more other microbes of a different species or strain. In certain aspects, the combination of two or more microbes forms a consortia or consortium. The terms consortia and consortium are utilized interchangeably.

[0023] In certain aspects, the disclosure provides for the development of highly functional microbial consortia that help promote the development and expression of a desired phenotypic or genotypic plant trait. In some embodiments, the consortia of the present disclosure possess functional attributes that are not found in nature, when the individual microbes are living alone. That is, in various embodiments, the combination of particular microbial species into consortia, leads to the microbial combination possessing functional attributes that are not possessed by any one individual member of the consortia when considered alone.

[0024] In some embodiments, this functional attribute possessed by the microbial consortia is the ability to impart one or more beneficial properties to a plant species, for example: increasedgrowth, increased yield, increased nutrient utilization (e.g., nitrogen, phosphate, and the like), increased nitrogen utilization efficiency, increased stress tolerance, increased drought tolerance, increased photosynthetic rate, enhanced water use efficiency, increased pathogen resistance, modifications to plant architecture that don’t necessarily impact plant yield, but rather address plant functionality, etc. Further contemplated are beneficial properties of pest resistance and / or tolerance, comprising an adverse effect against a nematode, insect, or other pest.

[0025] The ability to impart these beneficial properties upon a plant is not possessed, in some embodiments, by the individual microbes as they would occur in nature. Rather, in some embodiments, it is by the hand of man combining these microbes into consortia that a functional composition is developed, said functional composition possessing attributes and functional properties that do not exist in nature. In some embodiments, the consortia may include microbes that have been genetically edited, altered, or modified through the modification of cellular compositions, including DNA, RNA, proteins and / or combinations of the same, via techniques known to those of ordinary skill in the art.

[0026] However, in other embodiments, the disclosure provides for individual isolated and biologically pure microbes that are capable of imparting beneficial properties upon a desired plant species, without the need to combine said microbes into consortia.

[0027] In some embodiments, the microbe is a strain of the genus Paenibacillus that has been genetically modified to improve nitrogen fixation capabilities. The one or more genetic modifications are characterized as providing improved nitrogen fixation activity to the genetically modified microbe, as compared to a non-genetically modified strain of the microbe.

[0028] The disclosure therefore offers an environmentally sustainable solution that allows farmers to increase yields of important crops that is not reliant upon increased utilization of synthetic fertilizer, herbicides, and / or pesticides. For example, in one aspect, the present disclosure describes isolated microbes that are genetically modified to improve the nitrogen fixation ability of the microbe. In some embodiments, an endogenous m' / 'gcnc of the isolated microbes, particularly one more regions between known genes (“intergenic regions”), is / are genetically modified to alter the nitrogen fixation capability of the microbe.

[0029] The present disclosure further relates to agricultural compositions that include one or more strains of the isolated, genetically modified microbes disclosed herein and an agriculturally acceptable carrier. In some embodiments, the agricultural compositions include one or moreadditional agriculturally beneficial agents (e.g. fertilizers, biofertilizers, bionematicides, bio stimulants, synthetic pesticides, and / or synthetic herbicides).

[0030] Also disclosed herein are methods of imparting one or more beneficial traits to a plant, where the methods include applying an agriculturally effective amount of one or more of the isolated, genetically modified microbes or agricultural compositions disclosed herein.

[0031] Any strain disclosed herein may further be combined with one or more additional microbes, which may form a microbial consortia. The microbial consortia can be any combination of one or more individual microbes. In certain embodiments, the microbial consortia comprise two microbes, or three microbes, or four microbes, or five microbes, or six microbes, or seven microbes, or eight microbes, or nine microbes, or 10 microbes, or more than 10 microbes.

[0032] Another object of the disclosure is to design a microbial consortium, which is able to perform multidimensional activities in common. In certain aspects, the microbes comprising the consortium act synergistically. In aspects, the effect that the microbial consortium has on a certain plant characteristic is greater than the effect that would be observed had any one individual microbial member of the consortium been utilized singularly. That is, in some aspects, the consortium exhibits a greater than additive effect upon a desired plant characteristic, as compared to the effect that would be found if any individual member of the consortium had been utilized by itself.

[0033] In some aspects, the consortia lead to the establishment of other plant-microbe interactions, e.g., by acting as primary colonizers or founding populations that set the trajectory for the future microbiome development.

[0034] In embodiments, the disclosure is directed to synergistic combinations (or mixtures) of microbial isolates.

[0035] In some aspects, the consortia taught herein provide a wide range of agricultural applications, including: improvements in yield of grain, fruit, and flowers; improvements in growth of plant pails; improved ability to utilize nutrients (e.g., nitrogen, phosphate, and the like), improved resistance to disease; biopesticidal effects including improved resistance to fungi, insects, and nematodes; improved survivability in extreme climate; and improvements in other desired plant phenotypic characteristics. Significantly, these benefits to plants and / oradverse effect on targeted pests and / or pathogens can be obtained without any hazardous side effects to the environment.

[0036] In some aspects, the individual microbes of the disclosure, or consortia comprising same, can be combined into an agriculturally acceptable composition.

[0037] In some embodiments, the agricultural compositions of the present disclosure include, but are not limited to: wetters, compatibilizing agents, antifoam agents, cleaning agents, sequestering agents, drift reduction agents, neutralizing agents, buffers, corrosion inhibitors, dyes, odorants, spreading agents, penetration aids, sticking agents, binders , dispersing agents, thickening agents, stabilizers, emulsifiers, freezing point depressants, antimicrobial agents, fertilizers, pesticides, nematicides, insecticides, herbicides, inert carriers, polymers, and the like.

In embodiments, the seed coating may be applied to a naked and untreated seed. In other embodiments, the seed coating may be applied to a previously treated seed. Thus, in some embodiments, the present disclosure teaches a method of treating a seed comprising applying an isolated bacterial strain or a microbial consortium to a seed. In certain embodiments, the isolated bacterial strain or microbial consortium is applied as an agricultural composition including an agriculturally acceptable carrier. In some embodiments, the agricultural compositions may be formulated as: a soil drench, a foliar spray, a dip treatment, an in-furrow treatment, a soil amendment, granules, a broadcast treatment, a post-harvest disease control treatment, or a seed treatment. In some embodiments, the agricultural compositions may be applied alone in or in rotation spray programs with other agricultural products. In some embodiments, the agricultural compositions may be compatible with tank mixing. In some embodiments, the agricultural compositions may be compatible with tank mixing with other agricultural products. In some embodiments, the agricultural compositions may be compatible with equipment used for ground, aerial, and irrigation applications.

[0039] In some embodiments, the applied microbes may become endophytic and consequently may be present in the growing plant that was treated and its subsequent offspring. In other embodiments the microbes might be applied at the same time as a co-treatment with seed treatments.

[0040] In one embodiment of the present disclosure, the microbes are supplied in the form of granules, or plug, or soil drench that is applied to the plant growth media.

[0044] Still another object of the disclosure relates to the agricultural compositions being formulated to provide a high colony forming units (CFU) bacterial population or consortia. In some aspects, the agricultural compositions have adjuvants that provide for a pertinent shelf life. In embodiments, the CFU concentration of the taught agricultural compositions is higher than the concentration at which the microbes would exist naturally, outside of the disclosed methods. In another embodiment, the agricultural composition contains the microbial cells in a concentration of 10A2-10A12 CFU per gram of the carrier or 10A5-10A9 CFU per gram of the carrier.

In other aspects, the microbial cells are applied as a co-treatment together with another seed treatment at a rate of 10A5-10A9 CFU.

[0045] In aspects, the disclosure is directed to agricultural microbial formulations that promote plant growth. In aspects, the disclosure provides for the taught isolated microbes, and consortia comprising same, to be formulated as an agricultural bioinoculant. The taught bioinoculants can be applied to plants, seeds, or soil, or combined with fertilizers, pesticides, and other compatible amendments. Suitable examples of formulating bioinoculants comprising isolated microbes can be found in U.S. Pat. NO 7,097,830.

[0046] The disclosed microbial formulations can: lower the need for nitrogen containing fertilizers, solubilize minerals, provide biopesticidal protection of the plants, protect plants against pathogens (e.g., fungi, insects, and nematodes), and make available to the plant valuable nutrients, such as nitrogen and / or phosphate, thus reducing and eliminating the need for using chemical pesticides and chemical fertilizers.

[0051] The present disclosure provides that a plant element or plant part can be effectively augmented, by coating said plant element or plant part with an isolated microbe or microbial consortia, in an amount that is not normally found on the plant element or plant part.

[0052] Some embodiments described herein are methods for preparing an agricultural seed composition, or seed coating, comprising: contacting the surface of a seed with a formulationcomprising a purified microbial population that comprises at least one isolated microbe that is heterologous to, or rarely present on the seed.

[0129] While the following terms arc believed to be well understood by one of ordinary skill in the art, the following are set forth to facilitate explanation of the presently disclosed subject matter.

[0130] The term “a” or “an” refers to one or more of that entity, i.e., can refer to a plural referent. As such, the terms “a” or “an”, “one or more” and “at least one” are used interchangeably herein. In addition, reference to “an element” by the indefinite article “a” or “an” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there is one and only one of the elements.

[0131] As used herein the terms “microorganism” or “microbe” should be taken broadly. These terms are used interchangeably and include, but are not limited to, the two prokaryotic domains, Bacteria and Archaea, as well as eukaryotic Fungi and Protists. In some embodiments, the disclosure refers to the “microbes” of paragraphs present in the disclosure. This characterization can refer to not only the identified taxonomic bacterial genera of the tables, but also the identified taxonomic species, as well as the various novel and newly identified bacterial strains of said tables.

[0132] As used herein, the term "microbe" or "microorganism" refers to any species or taxon of microorganism, including, but not limited to, archaea, bacteria, microalgae, fungi (including mold and yeast species), mycoplasmas, microspores, nanobacteria, oomycetes, and protozoa. In some embodiments, a microbe or microorganism encompasses individual cells (e.g., unicellular microorganisms) or more than one cell e.g., multi-cellular microorganism). A "population of microorganisms" may thus refer to a multiple cells of a single microorganism, in which the cells share common genetic derivation.

[0133] As used herein, the term "bacterium" or "bacteria" refers in general to any prokaryotic organism, and may reference an organism from either Kingdom Eubacteria (Bacteria), Kingdom Archaebacteria (Archaea), or both. In some cases, bacterial genera or other taxonomic classifications may be in taxonomic flux, have been reassigned due to various reasons (such as but not limited to the evolving field of whole genome sequencing), and / or may be variable based on methodology, and it is understood that such nomenclature variabilities are within the scope of any claimed taxonomy. For example, certain species of the genus Erwinia have been described in the literature as belonging to genus Pantoea (Zhang, Y., Qiu, S. Examining phylogeneticrelationships of Erwinia and Pantoea species using whole genome sequence data. Antonie van Leeuwenhoek 108, 1037-1046 (2015).).

[0134] The term “16S” refers to the DNA sequence of the 16S ribosomal RNA (rRNA) sequence of a bacterium. 16S rRNA gene sequencing is a well-established method for studying phylogeny and taxonomy of bacteria.

[0166] As used herein, the term "fungus" or "fungi" refers in general to any organism from Kingdom Fungi. Historical taxonomic classification of fungi has been according to morphological presentation. Beginning in the mid- 1800' s, it was recognized that some fungi have a pleomorphic life cycle, and that different nomenclature designations were being used for different forms of the same fungus. In 1981, the Sydney Congress of the International Mycological Association laid out rules for the naming of fungi according to their status as anamorph, teleomorph, or holomorph (Taylor, J.W. One Fungus = One Name: DNA and fungal nomenclature twenty years after PCR. IMA Fungus 2, 113-120 (2011).). With the development of genomic sequencing, it became evident that taxonomic classification based on molecular phylogenetics did not align with morphological-based nomenclature (Shenoy, B.D., Jeewon, R. and Hyde, K.D. (2007). Impact of DNA sequence-data on the taxonomy of anamorphic fungi. Fungal Diversity 26: 1-54.). As a result, in 2011 the International Botanical Congress adopted a resolution approving the International Code of Nomenclature for Algae, Fungi, and Plants (Melbourne Code) (2012), with the stated outcome of designating "One Fungus = One Name" (Hawksworth, D.L. Managing and coping with names of pleomorphic fungi in a period of transition. IMA Fungus 3, 15-24 (2012)).

[0135] The term "Internal Transcribed Spacer" (“ITS”) refers to the spacer DNA (non-coding DNA) situated between the small-subunit ribosomal RNA (rRNA) and largc-subunit (LSU) rRNA genes in the chromosome or the corresponding transcribed region in the polycistronic rRNA precursor transcript. ITS gene sequencing is a well-established method for studying phylogeny and taxonomy of fungi. In some cases, the "Large SubUnit" (“LSU”) sequence is used to identify fungi. LSU gene sequencing is a well-established method for studying phylogeny and taxonomy of fungi. Some fungal microbes of the present invention may be described by an ITS sequence and some may be described by an LSU sequence. Both are understood to be equally descriptive and accurate for determining taxonomy.

[0136] The term “microbial consortia” or “microbial consortium” refers to a subset of a microbial community of individual microbial species, or strains of a species, which can bedescribed as carrying out a common function, or can be described as participating in, or leading to, or correlating with, a recognizable parameter or plant phenotypic trait. The community may comprise one or more species, or strains of a species, of microbes. In some instances, the microbes coexist within the community symbiotically.

[0137] The term “microbial community” means a group of microbes comprising two or more species or strains. Unlike microbial consortia, a microbial community does not have to be carrying out a common function, or does not have to be participating in, or leading to, or correlating with, a recognizable parameter or plant phenotypic trait.

[0138] The term “accelerated microbial selection” or “AMS” is used interchangeably with the term “directed microbial selection” or “DMS” and refers to the iterative selection methodology that was utilized, in some embodiments of the disclosure, to derive the claimed microbial species or consortia of said species.

[0139] As used herein, “isolate,” “isolated,” “isolated microbe,” and like terms, are intended to mean that the one or more microorganisms has been separated from at least one of the materials with which it is associated in a particular environment (for example soil, water, plant tissue).

[0140] Thus, an “isolated microbe” does not exist in its naturally occurring environment; rather, it is through the various techniques described herein that the microbe has been removed from its natural setting and placed into a non-naturally occurring state of existence. Thus, the isolated strain may exist as, for example, a biologically pure culture, or as spores (or other forms of the strain) in association with an agricultural carrier.

[0141] In certain aspects of the disclosure, the isolated microbes exist as isolated and biologically pure cultures. It will be appreciated by one of skill in the art, that an isolated and biologically pure culture of a particular microbe, denotes that said culture is substantially free (within scientific reason) of other living organisms and contains only the individual microbe in question. The culture can contain varying concentrations of said microbe. The present disclosure notes that isolated and biologically pure microbes often “necessarily differ from less pure or impure materials.” See, e.g., In re Bergstrom, 427 F.2d 1394, (CCPA 1970) (discussing purified prostaglandins), see also, In re Bergy, 596 F.2d 952 (CCPA 1979) (discussing purified microbes), see also, Parke-Davis & Co. v. H.K. Mulford & Co., 189 F. 95 (S.D.N.Y. 1911) (Learned Hand discussing purified adrenaline), affirmed in part, reversed in pail, 196 F. 496 (2d Cir. 1912), each of which are incorporated herein by reference. Furthermore, in some aspects, thedisclosure provides for certain quantitative measures of the concentration, or purity limitations, that must be found within an isolated and biologically pure microbial culture. The presence of these purity values, in certain embodiments, is a further attribute that distinguishes the presently disclosed microbes from those microbes existing in a natural state. See, e.g., Merck & Co. v. Olin Mathieson Chemical Corp., 253 F.2d 156 (4th Cir. 1958) (discussing purity limitations for vitamin B12 produced by microbes).

[0142] As used herein, “individual isolates” should be taken to mean a composition, or culture, comprising a predominance of a single genera, species, or strain, of microorganism, following separation from one or more other microorganisms. The phrase should not be taken to indicate the extent to which the microorganism has been isolated or purified. However, “individual isolates” can comprise substantially only one genus, species, or strain, of microorganism.

[0143] With respect to microbes, the term “modified” means that the microbe has been changed in some way, as compared to the natural state in which it was found. In this context, “modified” is synonymous with “engineered”, and indicates that the hand of man was involved with creating the modification. In some cases, the modification includes the change of a polynucleotide within the microbe, for example in its genome. Modifications may include deletion, insertion, replacement, and / or chemical alteration of at least one nucleotide, and may result in a change in the phenotype of the microbe e.g., upregulation of a particular pathway, downregulation of a particular pathway, knockout of a gene or protein function) and / or a change in the phenotype of another, heterologous organism with which the microbe is or becomes associated.

[0144] By the term “associated”, it is meant that a microbe is physically in contact with another organism or component or composition.

[0145] The term “modulate” (or “modulated”, “modulating”, and the like) means that a particular characteristic has been changed from what was previously existing. For example, modulated nitrogen fixation ability (or capability) means that an organism has an increase in nitrogen fixation, a decrease in nitrogen fixation, a different temporal or spatial expression of nitrogen fixation, or other change from the previous nitrogen fixation capability.

[0146] The term “growth medium” as used herein, is any medium which is suitable to support growth of a plant. By way of example, the media may be natural or artificial including, but not limited to: soil, potting mixes, bark, vermiculite, hydroponic solutions alone and applied to solid plant support systems, and tissue culture gels. It should be appreciated that the media may beused alone or in combination with one or more other media. It may also be used with or without the addition of exogenous nutrients and physical support systems for roots and foliage.

[0147] In one embodiment, the growth medium is a naturally occurring medium such as soil, sand, mud, clay, humus, regolith, rock, or water. In another embodiment, the growth medium is artificial. Such an artificial growth medium may be constructed to mimic the conditions of a naturally occurring medium; however, this is not necessary. Artificial growth media can be made from one or more of any number and combination of materials including sand, minerals, glass, rock, water, metals, salts, nutrients, water. In one embodiment, the growth medium is sterile. In another embodiment, the growth medium is not sterile.

[0148] The medium may be amended or enriched with additional compounds or components, for example, a component which may assist in the interaction and / or selection of specific groups of microorganisms with the plant and each other. For example, antibiotics (such as penicillin) or sterilants (for example, quaternary ammonium salts and oxidizing agents) could be present and / or the physical conditions (such as salinity, plant nutrients (for example organic and inorganic minerals (such as phosphorus, nitrogenous salts, ammonia, potassium and micronutrients such as cobalt and magnesium), pH, and / or temperature) could be amended.

[0149] The term “plant” generically includes whole plants, plant organs, plant tissues, seeds, plant cells, seeds and progeny of the same. Plant cells include, without limitation, cells from seeds, suspension cultures, embryos, meristematic regions, callus tissue, leaves, roots, shoots, gametophytes, sporophytes, pollen and microspores. As used herein, the term “plant element” refers to plant cells, plant protoplasts, plant cell tissue cultures from which plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants such as embryos, pollen, ovules, seeds, leaves, flowers, branches, fruit, kernels, ears, cobs, husks, stalks, roots, root tips, anthers, and the like, as well as the parts themselves. Progeny, variants, and mutants of the regenerated plants are also included within the scope of the invention, provided that these parts comprise the introduced polynucleotides.

[0150] A “plant element” is intended to reference either a whole plant or a plant component, which may comprise differentiated and / or undifferentiated tissues, for example but not limited to plant tissues, parts, and cell types. In one embodiment, a plant element is one of the following: whole plant, seedling, meristematic tissue, ground tissue, vascular tissue, dermal tissue, seed, leaf, root, shoot, stem, flower, fruit, stolon, bulb, tuber, corm, keiki, shoot, bud, tumor tissue, andvarious forms of cells and culture (e.g., single cells, protoplasts, embryos, callus tissue). The term “plant organ” refers to plant tissue or a group of tissues that constitute a morphologically and functionally distinct part of a plant. As used herein, a “plant part” is synonymous to a “portion” of a plant, and refers to any part of the plant, and can include distinct tissues and / or organs, and may be used interchangeably with the term “tissue” throughout.

[0151] Similarly, a “plant reproductive element” is intended to generically reference any part of a plant that is able to initiate other plants via either sexual or asexual reproduction of that plant, for example but not limited to: seed, seedling, root, shoot, cutting, scion, graft, stolon, bulb, tuber, corm, keiki, or bud. The plant element may be in plant or in a plant organ, tissue culture, or cell culture.

[0152] “Progeny” comprises any subsequent generation of an organism, produced via sexual or asexual reproduction.

[0153] “Grain” is intended to mean the mature seed produced by commercial growers for purposes other than growing or reproducing the species.

[0154] The term “monocotyledonous” or “monocot” refers to the subclass of angiosperm plants also known as “monocotyledoneae”, whose seeds typically comprise only one embryonic leaf, or cotyledon. The term includes references to whole plants, plant elements, plant organs (e.g., leaves, stems, roots, etc.), seeds, plant cells, and progeny of the same.

[0155] The term “dicotyledonous” or “dicot” refers to the subclass of angiosperm plants also knows as “dicotyledoneae”, whose seeds typically comprise two embryonic leaves, or cotyledons. The term includes references to whole plants, plant elements, plant organs e.g., leaves, stems, roots, etc.), seeds, plant cells, and progeny of the same.

[0156] As used herein, the term “cultivar” refers to a variety, strain, or race, of plant that has been produced by horticultural or agronomic techniques and is not normally found in wild populations.

[0157] As used herein, “improved” should be taken broadly to encompass improvement of a characteristic of a plant, as compared to a control plant, or as compared to a known average quantity associated with the characteristic in question. For example, “improved” plant biomass associated with application of a beneficial microbe, or consortia, of the disclosure can be demonstrated by comparing the biomass of a plant treated by the microbes taught herein to the biomass of a control plant not treated. Alternatively, one could compare the biomass of a planttreated by the microbes taught herein to the average biomass normally attained by the given plant, as represented in scientific or agricultural publications known to those of skill in the art. In the present disclosure, “improved” does not necessarily demand that the data be statistically sigm / icant (e.g., p < 0.05); rather, any quantifiable difference demonstrating that one value (e.g., the average treatment value) is different from another (e.g., the average control value) can rise to the level of “improved.”

[0158] As used herein, “inhibiting and suppressing” and like terms should not be construed to require complete inhibition or suppression, although this may be desired in some embodiments.

[0159] As used herein, the term “genotype” refers to the genetic makeup of an individual cell, cell culture, tissue, organism (e.g., a plant), or group of organisms.

[0160] The compositions and methods herein may provide for an improved “agronomic trait” or “trait of agronomic importance” or “trait of agronomic interest” to a plant, which may include, but not be limited to, the following: disease resistance, drought tolerance, heat tolerance, cold tolerance, salinity tolerance, metal tolerance, herbicide tolerance, improved water use efficiency, improved nitrogen utilization, improved nitrogen fixation, pest resistance, herbivore resistance, pathogen resistance, yield improvement, health enhancement, vigor improvement, growth improvement, photosynthetic capability improvement, nutrition enhancement, altered protein content, altered oil content, increased biomass, increased shoot length, increased root length, improved root architecture, modulation of a metabolite, modulation of the proteome, increased seed weight, altered seed carbohydrate composition, altered seed oil composition, altered seed protein composition, altered seed nutrient composition, as compared to an isoline plant not comprising a modification derived from the methods or compositions herein

[0161] “Agronomic trait potential” is intended to mean a capability of a plant element for exhibiting a phenotype, preferably an improved agronomic trait, at some point during its life cycle, or conveying said phenotype to another plant element with which it is associated in the same plant.

[0162] As used herein, the term “molecular' marker”, “marker”, or “genetic marker” refers to an indicator that is used in methods for visualizing differences in characteristics of nucleic acid sequences. Examples of such indicators are restriction fragment length polymorphism (RFLP) markers, amplified fragment length polymorphism (AFLP) markers, single nucleotide polymorphisms (SNPs), insertion mutations, micro satellite markers (SSRs), sequence-characterized amplified regions (SCARs), cleaved amplified polymorphic sequence (CAPS) markers or isozyme markers or combinations of the markers described herein which defines a specific genetic and chromosomal location. Mapping of molecular markers in the vicinity of an allele is a procedure which can be performed by the average person skilled in molecular- biological techniques.

[0163] As used herein, the term “trait” refers to a characteristic or phenotype. For example, in the context of some embodiments of the present disclosure, yield of a crop relates to the amount of marketable biomass produced by a plant (e.g., fruit, fiber, grain). Desirable traits may also include other plant characteristics, including but not limited to: water use efficiency, nutrient use efficiency, production, mechanical harvestability, fruit maturity, shelf life, pest / disease resistance, early plant maturity, tolerance to stresses, etc. A trait may be inherited in a dominant or recessive manner, or in a partial or incomplete-dominant manner. A trait may be monogenic (i.e., determined by a single locus) or polygenic (i.e., determined by more than one locus) or may also result from the interaction of one or more genes with the environment.

[0164] As used herein, the term “phenotype” refers to the observable characteristics of an individual cell, cell culture, organism (e.g., a plant), or group of organisms which results from the interaction between that individual’s genetic makeup (i.e., genotype) and the environment.

[0165] As used herein, a “synthetic nucleotide sequence” or “synthetic polynucleotide sequence” is a nucleotide sequence that is not known to occur in nature or that is not naturally occurring. Generally, such a synthetic nucleotide sequence will comprise at least one nucleotide difference when compared to any other naturally occurring nucleotide sequence.

[0166] As used herein, the term “nucleic acid” refers to a polymeric form of nucleotides of any length, either ribonucleotides or deoxyribonucleotides, or analogs thereof. This term refers to the primary structure of the molecule, and thus includes double- and single-stranded DNA, as well as double- and single-stranded RNA. It also includes modified nucleic acids such as methylated and / or capped nucleic acids, nucleic acids containing modified bases, backbone modifications, and the like. The terms “nucleic acid” and “nucleotide sequence” are used interchangeably.

[0167] As used herein, the term “gene” refers to any segment of DNA associated with a biological function. Thus, genes include, but are not limited to, coding sequences and / or the regulatory sequences required for their expression. Genes can also include non-expressed DNA segments that, for example, form recognition sequences for other proteins. Genes can beobtained from a variety of sources, including cloning from a source of interest or synthesizing from known or predicted sequence information, and may include sequences designed to have desired parameters.

[0168] As used herein, the term “homologous” or “homologue”, “homolog”, or “ortholog” is known in the art and refers to related sequences that share a common ancestor or family member and are determined based on the degree of sequence identity. The terms “homology,” “homologous,” “substantially similar” and “corresponding substantially” are used interchangeably herein. They refer to nucleic acid fragments wherein changes in one or more nucleotide bases do not affect the ability of the nucleic acid fragment to mediate gene expression or produce a certain phenotype. These terms also refer to modifications of the nucleic acid fragments of the instant disclosure such as deletion or insertion of one or more nucleotides that do not substantially alter the functional properties of the resulting nucleic acid fragment relative to the initial, unmodified fragment. It is therefore understood, as those skilled in the art will appreciate, that the disclosure encompasses more than the specific exemplary sequences. These terms describe the relationship between a gene found in one species, subspecies, variety, cultivar or strain and the corresponding or equivalent gene in another species, subspecies, variety, cultivar or strain. For purposes of this disclosure homologous sequences are compared.“Homologous sequences” or “homologues” or “orthologs” are thought, believed, or known to be functionally related. A functional relationship may be indicated in any one of a number of ways, including, but not limited to: (a) degree of sequence identity and / or (b) the same or similar biological function. Preferably, both (a) and (b) are indicated. Homology can be determined using software programs readily available in the art, such as those discussed in Current Protocols in Molecular Biology (F.M. Ausubel et al., eds., 1987) Supplement 30, section 7.718, Table 7.71. Some alignment programs are MacVector (Oxford Molecular Ltd, Oxford, U.K.), ALIGN Plus (Scientific and Educational Software, Pennsylvania) and AlignX (Vector NTI, Invitrogen, Carlsbad, CA). Another alignment program is Sequencher (Gene Codes, Ann Arbor, Michigan), using default parameters.

[0169] As used herein, the term “nucleotide change” refers to, e.g., nucleotide substitution, deletion, insertion, chemical alteration, or any of the preceding, as is well understood in the art.

[0170] As used herein, the term “protein modification” refers to, e.g., amino acid substitution, amino acid modification, deletion, and / or insertion, as is well understood in the art.

[0171] As used herein, the term “at least a portion” or “fragment” of a nucleic acid or polypeptide means a portion having the minimal size characteristics of such sequences, or any larger fragment of the full-length molecule, up to and including the full-length molecule. A fragment of a polynucleotide of the disclosure may encode a biologically active portion of a genetic regulatory element. A biologically active portion of a genetic regulatory element can be prepared by isolating a portion of one of the polynucleotides of the disclosure that comprises the genetic regulatory element and assessing activity as described herein. Similarly, a portion of a polypeptide may be 4 amino acids, 5 amino acids, 6 amino acids, 7 amino acids, and so on, going up to the full-length polypeptide. The length of the portion to be used will depend on the particular application. A portion of a nucleic acid useful as a hybridization probe may be as short as 12 nucleotides; in some embodiments, it is 20 nucleotides. A portion of a polypeptide useful as an epitope may be as short as 4 amino acids. A portion of a polypeptide that performs the function of the full-length polypeptide would generally be longer than 4 amino acids.

[0172] The term “primer” as used herein refers to an oligonucleotide which is capable of annealing to the amplification target allowing a DNA polymerase to attach, thereby serving as a point of initiation of DNA synthesis when placed under conditions in which synthesis of primer extension product is induced, i.e., in the presence of nucleotides and an agent for polymerization such as DNA polymerase and at a suitable temperature and pH. The (amplification) primer is preferably single stranded for maximum efficiency in amplification. Preferably, the primer is an oligodeoxyribonucleotide. The primer must be sufficiently long to prime the synthesis of extension products in the presence of the agent for polymerization. The exact lengths of the primers will depend on many factors, including temperature and composition (A / T vs. G / C content) of primer. A pair of bi-directional primers consists of one forward and one reverse primer as commonly used in the art of DNA amplification such as in PCR amplification.

[0173] The terms “stringency” or “stringent hybridization conditions” refer to hybridization conditions that affect the stability of hybrids, e.g., temperature, salt concentration, pH, formamide concentration and the like. These conditions are empirically optimized to maximize specific binding and minimize non-specific binding of primer or probe to its target nucleic acid sequence. The terms as used include reference to conditions under which a probe or primer will hybridize to its target sequence, to a delectably greater degree than other sequences (e.g., at least 2-fold over background). Stringent conditions are sequence dependent and will be different indifferent circumstances. Longer sequences hybridize specifically at higher temperatures.Generally, stringent conditions arc selected to be about 5° C lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength and pH. The Tm is the temperature (under defined ionic strength and pH) at which 50% of a complementary target sequence hybridizes to a perfectly matched probe or primer. Typically, stringent conditions will be those in which the salt concentration is less than about 1.0 M Na+ ion, typically about 0.01 to 1.0 M Na + ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30° C for short probes or primers (e.g., 10 to 50 nucleotides) and at least about 60° C for long probes or primers (e.g., greater than 50 nucleotides). Stringent conditions may also be achieved with the addition of destabilizing agents such as formamide. Exemplary low stringent conditions or “conditions of reduced stringency” include hybridization with a buffer solution of 30% formamide, 1 M NaCl, 1% SDS at 37° C and a wash in 2xSSC at 40° C. Exemplary high stringency conditions include hybridization in 50% formamide, IM NaCl, 1% SDS at 37° C, and a wash in O.lxSSC at 60° C. Hybridization procedures are well known in the ail and are described by e.g., Ausubel et al., 1998 and Sambrook et al., 2001. In some embodiments, stringent conditions are hybridization in 0.25 M Na2HPO4 buffer (pH 7.2) containing 1 mM Na2EDTA, 0.5-20% sodium dodecyl sulfate at 45°C, such as 0.5%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19% or 20%, followed by a wash in 5xSSC, containing 0.1% (w / v) sodium dodecyl sulfate, at 55°C to 65°C.

[0174] In some embodiments, the cell or organism has at least one heterologous trait. As used herein, the term “heterologous trait” refers to a phenotype imparted to a cell or organism by an exogenous molecule or other organism (e.g., a microbe), DNA segment, heterologous polynucleotide or heterologous nucleic acid.

[0175] Various changes in phenotype are of interest to the present disclosure, including but not limited to modifying the fatty acid composition in a plant, altering the amino acid content of a plant, altering a plant's pathogen defense mechanism, increasing a plant’s yield of an economically important trait (e.g., grain yield, forage yield, etc.) and the like. These results can be achieved by providing expression of heterologous products or increased expression of endogenous products in plants using the methods and compositions of the present disclosure

[0176] A “synthetic combination” can include a combination of a plant and a microbe of the disclosure. The combination may be achieved, for example, by coating the surface of a seed of aplant, such as an agricultural plant, or host plant tissue (root, stem, leaf, etc.), with a microbe of the disclosure. Further, a “synthetic combination” can include a combination of microbes of various strains or species. Synthetic combinations have at least one variable that distinguishes the combination from any combination that occurs in nature. That variable may be, inter alia, a concentration of microbe on a seed or plant tissue that does not occur naturally, or a combination of microbe and plant that does not naturally occur, or a combination of microbes or strains that do not occur naturally together. In each of these instances, the synthetic combination demonstrates the hand of man and possesses structural and / or functional attributes that are not present when the individual elements of the combination are considered in isolation.

[0177] In some embodiments, a microbe can be “endogenous” to a seed or plant. As used herein, a microbe is considered “endogenous” to a plant or seed, if the microbe is derived from the plant specimen from which it is sourced. That is, if the microbe is naturally found associated with said plant. In embodiments in which an endogenous microbe is applied to a plant, then the endogenous microbe is applied in an amount that differs from the levels found on the plant in nature. Thus, a microbe that is endogenous to a given plant can still form a synthetic combination with the plant, if the microbe is present on said plant at a level that does not occur naturally.

[0178] In some embodiments, a composition (such as a microbe) can be “heterologous” (also termed “exogenous”) to another composition (such as a seed or plant), and in some aspects is referred to herein as a “heterologous composition”. As used herein, a microbe is considered “heterologous” to a plant or seed, if the microbe is not derived from the plant specimen from which it is sourced. That is, if the microbe is not naturally found associated with said plant. For example, a microbe that is normally associated with leaf tissue of a maize plant is considered exogenous to a leaf tissue of another maize plant that naturally lacks said microbe. In another example, a microbe that is normally associated with a maize plant is considered exogenous to a wheat plant that naturally lacks said microbe. Similarly, a nucleotide or amino acid sequence may be considered “heterologous” to a locus within an organism, or in a different organism from which it was originally obtained. Broadly, “heterologous” means not naturally occurring in that particular location, or at that particular time, or with a particular additional component.

[0179] A composition is “heterologously disposed” when mechanically or manually applied, artificially inoculated, associated with, or disposed onto or into a plant element, seedling, plant or onto or into a plant growth medium or onto or into a treatment formulation so that the treatmentexists on or in the plant element, seedling, plant, plant growth medium, or formulation in a manner not found in nature prior to the application of the treatment, e.g., said combination which is not found in nature in that plant variety, at that stage in plant development, in that plant tissue, in that abundance, or in that growth environment (for example, drought). In some embodiments, such a manner is contemplated to be selected from the group consisting of: the presence of the microbe; presence of the microbe in a different number of cells, concentration, or amount; the presence of the microbe in a different plant element, tissue, cell type, or other physical location in or on the plant; the presence of the microbe at different time period, e.g., developmental phase of the plant or plant element, time of day, time of season, and combinations thereof. In some embodiments, “heterologously disposed” means that the microbe being applied to a different tissue or cell type of the plant element than that in which the microbe is naturally found. In some embodiments, “heterologously disposed” means that the microbe is applied to a developmental stage of the plant element, seedling, or plant in which said microbe is not naturally associated, but may be associated at other stages. For example, if a microbe is normally found at the flowering stage of a plant and no other stage, a microbe applied at the seedling stage may be considered to be heterologously disposed. In some embodiments, a microbe is heterologously disposed the microbe is normally found in the root tissue of a plant element but not in the leaf tissue, and the microbe is applied to the leaf. In another non-limiting example, if a microbe is naturally found in the mesophyll layer of leaf tissue but is being applied to the epithelial layer, the microbe would be considered to be heterologously disposed. In some embodiments, “heterologously disposed” means that the native plant element, seedling, or plant does not contain detectable levels of the microbe in that same plant element, seedling, or plant. In some embodiments, “heterologously disposed” means that the microbe being applied is at a greater concentration, number, or amount of the plant element, seedling, or plant, than that which is naturally found in said plant element, seedling, or plant. For example, a microbe is heterologously disposed when present at a concentration that is at least 1.5 times greater, between 1.5 and 2 times greater, 2 times greater, between 2 and 3 times greater, 3 times greater, between 3 and 5 times greater, 5 times greater, between 5 and 7 times greater, 7 times greater, between 7 and 10 times greater, 10 times greater, or even greater than 10 times higher number, amount, or concentration than the concentration that was present prior to the disposition of said microbe. In another non-limiting example, a microbe that is naturally found in a tissue of acupressaceous tree would be considered heterologous to tissue of a maize, wheat, cotton, soybean plant. In another example, a microbe that is naturally found in leaf tissue of a maize, spring wheat, cotton, soybean plant is considered heterologous to a leaf tissue of another maize, spring wheat, cotton, soybean plant that naturally lacks said microbe, or comprises the microbe in a different quantity.

[0180] Microbes can also be “heterologously disposed” on a given plant tissue. This means that the microbe is placed upon a plant tissue that it is not naturally found upon. For instance, if a given microbe only naturally occurs on the roots of a given plant, then that microbe could be exogenously applied to the above-ground tissue of a plant and would thereby be “heterologously disposed” upon said plant tissue. As such, a microbe is deemed heterologously disposed, when applied on a plant that does not naturally have the microbe present or does not naturally have the microbe present in the number that is being applied.

[0181] The compositions and methods herein may provide for a “modulated” “agronomic trait” or “trait of agronomic importance” to a host plant, which may include, but not be limited to, the following: altered oil content, altered protein content, altered seed carbohydrate composition, altered seed oil composition, and altered seed protein composition, chemical tolerance, cold tolerance, delayed senescence, disease resistance, drought tolerance, ear weight, growth improvement, health enhancement, heat tolerance, herbicide tolerance, herbivore resistance, improved nitrogen fixation, improved nitrogen utilization, improved root architecture, improved water use efficiency, increased biomass, increased root length, increased seed weight, increased shoot length, increased yield, increased yield under water-limited conditions, kernel mass, kernel moisture content, metal tolerance, number of ears, number of kernels per ear, number of pods, nutrition enhancement, pathogen resistance, pest resistance, photosynthetic capability improvement, salinity tolerance, stay-green, vigor improvement, increased dry weight of mature seeds, increased fresh weight of mature seeds, increased number of mature seeds per plant, increased chlorophyll content, increased number of pods per plant, increased length of pods per plant, reduced number of wilted leaves per plant, reduced number of severely wilted leaves per plant, and increased number of non- wilted leaves per plant, a detectable modulation in the level of a metabolite, a detectable modulation in the level of a transcript, and a detectable modulation in the proteome, compared to an isoline plant grown from a seed without said seed treatment formulation. By the term “modulated”, it is intended to refer to a change in an agronomic traitthat is changed by virtue of the presence of the microbe(s), exudate, broth, metabolite, etc. In aspects, the modulation provides for the imparting of a beneficial trait.Microbes and Microorganisms

[0182] As used herein the term “microorganism” should be taken broadly. It includes, but is not limited to, prokaryotic Bacteria and Archaea, as well as eukaryotic Fungi and Protists.

[0183] In a particular embodiment, the microorganism is an endophyte, or an epiphyte, or a microorganism inhabiting the plant rhizosphere or rhizosheath. That is, the microorganism may be found present in the soil material adhered to the roots of a plant or in the area immediately adjacent a plant’s roots.

[0184] In one embodiment, the microorganism is an endophyte. Endophytes may benefit host plants by preventing pathogenic organisms from colonizing them. Extensive colonization of the plant tissue by endophytes creates a “barrier effect,” where the local endophytes outcompete and prevent pathogenic organisms from taking hold. Endophytes may also produce chemicals which inhibit the growth of competitors, including pathogenic organisms.

[0185] In certain embodiments, the microorganism is unculturable. This should be taken to mean that the microorganism is not known to be culturable or is difficult to culture using methods known to one skilled in the art.

[0186] Microorganisms of the present disclosure may be collected or obtained from any source or contained within and / or associated with material collected from any source.

[0187] In one embodiment, a microorganism or a combination of microorganisms, may provide likely or predicted benefit to a plant. For example, the microorganism may be predicted to: improve nitrogen fixation; release phosphate from the soil organic matter; release phosphate from the inorganic forms of phosphate (e.g., rock phosphate); “fix carbon” in the root microsphere; live in the rhizosphere of the plant thereby assisting the plant in absorbing nutrients from the surrounding soil and then providing these more readily to the plant; increase the number of nodules on the plant roots and thereby increase the number of symbiotic nitrogen fixing bacteria (e.g., Rhizobiuni species) per plant and the amount of nitrogen fixed by the plant; elicit plant defensive responses such as ISR (induced systemic resistance) or SAR (systemic acquired resistance) which help the plant resist the invasion and spread of pathogenic microorganisms; compete with microorganisms deleterious to plant growth or health by antagonism, or competitive utilization of resources such as nutrients or space; change the color of one or morepart of the plant, or change the chemical profile of the plant, its smell, taste or one or more other quality.

[0188] The microorganisms of the disclosure may be isolated in substantially pure or mixed cultures. They may be concentrated, diluted, or provided in the natural concentrations in which they are found in the source material. For example, microorganisms from saline sediments may be isolated for use in this disclosure by suspending the sediment in fresh water and allowing the sediment to fall to the bottom. The water containing the bulk of the microorganisms may be removed by decantation after a suitable period of settling and either applied directly to the plant growth medium, or concentrated by filtering or centrifugation, diluted to an appropriate concentration and applied to the plant growth medium with the bulk of the salt removed. By way of further example, microorganisms from mineralized or toxic sources may be similarly treated to recover the microbes for application to the plant growth material to minimize the potential for damage to the plant.

[0189] In some embodiments, a mixed population of microorganisms is used in the methods of the disclosure.Nitrogen Fixation in Bacteria

[0190] Glutamine (Gin) is the universal nitrogen signal in all free-living diazotrophs (see, for example, Wang et al., PLOS Genetics, 2018). Gram-negative bacteria, such as Klebsiella and Pseudomonas, have well-elucidated nitrogen pathways, and have easier, more predictable gene delivery and expression for genome modified strains. In the gram-negative bacterium Klebsiella variicola, NifL is the negative regulator of the m / opcron. When intracellular glutamine is high (nitrogen excess), NifL forms a repressor complex to inactivate the m / ’operon expression.

[0191] In the gram-negative bacterium Azospirillum, NifA activates transcription of the nif operon. Expression of nifA is regulated by glutamine through NtrB phosphorylation of NtrC. Nitrogenase is inactivated post-transcriptionally.

[0192] In contrast, gram-positive bacteria, such as Paenibacillus, are more difficult to transform and have less-studied nitrogen fixation pathways.

[0193] In gram-positive bacteria, thecluster encodes the nitrogen fixation genes which are regulated by GlnR. Binding of GlnR to Site I activates Nif expression, while binding of GlnR to Site II represses Nif expression. The nitrogenase enzyme complex in gram positive bacteria isencoded by 9-10 genes (e.g., in nitrogen-fixing Paenibacillus species) and activated / repressed by binding of GlnR to Site VII, respectively.

[0194] Thus, successful genome modification that results in greater nitrogen fixation capability for a gram-positive bacterium like Paenibacillus is not only surprising, but greatly needed in agricultural biotechnology. Because of the spore-forming capabilities of Paenibacillus, there is increased commercial potential for a product comprising a gene-edited Paenibacillus strain that improves nitrogen fixation for crop plants.

[0195] Thus, a gene target for improving nitrogen fixation in Paenibacillus is the Nif activator / repressor GlnR and its binding sites.

[0196] In Paenibacillus, the nz ’operon (cluster) comprises a number of genes, including: nifB, nifH, nifD, nifK, nifE, nifN, nifK, hesA and nifV. Although highly conserved among the Ni-fixing Paenibacillus strains, there are some variations in DNA sequences of the nif clusters, which can be divided into two sub-groups: Subgroup I and Subgroup II. The nine genes nifBHDKENKhesAnifV of the nif gene cluster within Sub-group I are contiguous, while there is an ORF of 261-561 bp, whose predicted product is unknown, between nifK and hesA within Sub-group II. Paenibacillus species P. polymyxa and P. tritici are examples of Subgroup I. Paenibacillus species P. albidus, P. anaericanus, P. azotifigens, P. borealis, P. donghaensis, P. ehimensis, P. graminis, P. jilunlii, P. odorifer, P. panacisoli, P. phoenicis, P. pocheonensis, P. rhizoplanae, P. silage, P. taohuashanense, P. thermophilus, P. typhae, and P. wynnii are examples of Subgroup II. Within the Paenibacillus genus, are two distinct Subgroups, Subgroup I and Subgroup II, each comprising a different operon composition. Subgroup I Paenibacillus, such as Paenibacillus polymyxa, comprise in this order: nifB, nifEl, nifD, nifK nifE, nifN, nifK, hesA, nifV. Subgroup II Paenibacillus, such as Paenibacillus graminis, comprise in this order: nifB, nifH, nifD, nifK, nifE, nifV, nifK, orfl, hesA, nifV.

[0197] Most biological nitrogen fixation is catalyzed by molybdenum-dependent nitrogenase, which is distributed within bacteria and archaea. This enzyme is composed of two component proteins, MoFe protein and Fe protein. The MoFe protein component is an a2p2 heterotetramer (encoded by nifD and nifK) that contains two metalloclusters; FeMo-co, a [Mo-7Fe-9S-C- homocitrate] cluster which serves as the active site of substrate binding and reduction and the P- cluster, a [8Fe-7S] cluster which shuttles electrons to FeMo-co. The Fe protein (encoded by nifH) is a homodimer bridged by an intersubunit [4Fe-4S] cluster that serves as the obligateelectron donor to the MoFe protein. The assembly pathway for the biosynthesis of nitrogenase is complex. Apart from the structural subunits encoded by nifH, nifD and nifK, several genes arc required for the biosynthesis of the metalloclusters, in addition to other gene products necessary to produce a fully functional enzyme. It is now well established from genetic and biochemical analysis that nifE, nifN, nifX nifB, nifQ, nifV, nifY and nifH contribute to the synthesis and insertion of FeMo-co into nitrogenase, that nifU, nifS, and nifZ play an important role in synthesis of metalloclusters and that nifM is required for proper folder of nitrogenase Fe protein. (Wang et al., PLoS Genet. 2013 Oct; 9(10): el003865).

[0198] Although the majority of present-day biological N2 reduction is catalyzed by the Mo- nitrogenase, two homologous alternative nitrogenases exist: V- and Fe-nitrogenase are important biological sources of fixed nitrogen in environments where Mo is limiting. V- and Fe- nitrogenase are encoded by the vzz / and anf genes. The Mo-, V- and Fe-nitrogenases are not equally distributed in nature. Most diazotrophs, such as K. pneumoniae, possesses only the Mo- nitrogenase, while some organisms, like A. vinelandii, possess all three types of nitrogenases, and other organisms, like Rhodobacter capsulatus and Rhodospirillum rubrum, carry the Mo- and Fe-nitrogenases (Xie et al., 2014, PLoS Genetics 10(3):el004231).

[0199] The nitrogenase enzyme complex consists of the following two conserved proteins: the MoFe protein, composed of subunits encoded by the nifD and nifK genes; and the Fe protein, encoded by the nifH gene. The nitrogenase iron protein gene, nifH, is one of the oldest existing functional genes in the history of gene evolution. The nucleotide sequences for coding regions of nifHDK genes among all nitrogen-fixing organisms are highly conserved. However, the copy numbers and arrangement of nifH, nifD, and nifK are different among the different diazotrophic bacteria.

[0200] According to the literature, the m / ' opcron is a cluster of components of genes that are transcribed as a single unit (monocistronic) under the regulation of GlnR binding to Binding Site I, upstream of the zz / / ' opcron.Novel Gene Editing Targets in Nitrogen Fixing Bacteria

[0201] Investigation of nitrogenase expression and activity in Paenibacillus species has revealed a conserved region of homology across strains / species that comprised a particular motif, that may be important for gene expression or activity, for example the expression of genes in a nitrogen fixation cluster.

[0202] This motif comprises 6- 14 nucleotides that comprise a consensus sequence of xTxTC, where “x” represents any nucleotide. The motif may be present on cither strand of the doublestranded polynucleotide. In some aspects, the motif comprises at least six, at least seven, at least eight, at least nine, at least ten, at least eleven, at least twelve, at least thirteen, or at least fourteen nucleotides.

[0203] All nitrogen-fixing Paenibacillus strains that were evaluated (over one hundred strains encompassing many different species) comprised this motif.

[0204] Exemplary polynucleotides that comprise this motif, in a region 5’ (upstream) of the canonical nif cluster, are given as SEQ ID NOs. 1-158. Exemplary species of Paenibacillus that comprise these sequences include, but are not limited to: donghaensis, durus, graminis, odorifer, panacisoli, phytohabitans, polymyxa, silagei, and typhae.

[0205] The region of homology may be enriched in adenine and thymine residues (AT-rich) and may, for example, provide sites for nucleoid-associated or other DNA-binding proteins to bind.

[0206] This motif region may share similarity to a noc binding site. The Paenibacillus consensus sequence for a noc binding site is ATTTCCCAAAATAT (SEQ ID NO: 164). The Bacillus consensus sequence for a noc binding site is ATTTCCCGGGAAAT (SEQ ID NO: 163).Genome Modification of Microbes

[0207] In some embodiments, the microorganism may have its genome altered in some way to provide an improved trait of interest, for example improvement of nitrogen fixation for non- leguminous crops.

[0208] Various methods are known in the art for modification of polynucleotides in a cell (which includes, without limitation, any polynucleotide sequence comprised within the cell, including genomic, chromosomal, and plasmid DNA). Briefly, a single- or double-strand break is introduced into a target polynucleotide (the subject of the modification), the result of which may be an insertion of at least one nucleotide, the deletion of at least one nucleotide, the replacement of at least one nucleotide, or any combination of the preceding, according to the desire of the practitioner.

[0209] The single- or double-strand break (SSB or DSB) may be accomplished by any of a number of methods, including the utilization of chemicals or radiation, a result of the process of homologous recombination, by the introduction of a specific or non-specific nuclease, or by any combination of the preceding.

[0210] Enzymes that effect polynucleotide cleavage are known in the art, and may include (without limitation): restriction endonucleases, mcganuclcascs, TALENs, Zinc Fingers, or Cas endonucleases.

[0211] Alternatively, homologous recombination may be utilized, leveraging identical or nearly- identical sequences flanking a polynucleotide of interest to insert or remove.

[0212] In some aspects, the present disclosure relates to isolated, genetically-modified microbes that have improved nitrogen fixing activity, as compared to non-genetically modified variants of the same species or strain of microbe.Microbial Consortia

[0213] In aspects, the disclosure provides microbial consortia comprising a combination of at least any two microbes, wherein one is a strain with a modified nif cluster. In some embodiments, the microbe is a Paenibacillus strain, in some cases a species selected from the group consisting of: polymyxa, tritici, albidus, anaericanus, azotifigens, borealis, donghaensis, ehimensis, graminis , jilunlii, odorifer, panacisoli, phoenicis, pocheonensis, rhizoplanae, silage, taohuashanense , thermophilus, typhae, and wynnii. In some embodiments, the Paenibacillus strain is of Subgroup I. In some embodiments, the Paenibacillus strain is of Subgroup II.

[0214] In certain embodiments, the consortia of the present disclosure comprise two microbes, or three microbes, or four microbes, or five microbes, or six microbes, or seven microbes, or eight microbes, or nine microbes, or ten or more microbes. Said microbes of the consortia are different microbial species, or different strains of a microbial species.Microbial-produced Compositions

[0215] In some cases, the microbes of the present disclosure may produce one or more compounds and / or have one or more activities, e.g., one or more of the following: production of a metabolite, production of a phytohormone such as auxin, production of acetoin, production of an antimicrobial compound, production of a siderophore, production of a polyketide, production of a phenazine, production of a cellulase, production of a pectinase, production of a chitinase, production of a glucanase, production of a xylanase or protease or organic acid or lipopeptide or polynucleotide or polypeptide, nitrogen fixation, mineral phosphate solubilization, or any combination and / or plurality of the preceding.

[0216] For example, a microbe of the disclosure may produce a phytohormone selected from the group consisting of an auxin, a cytokinin, a gibberellin, ethylene, a brassinostcroid, and abscisic acid.

[0217] Thus, a “metabolite produced by” a microbe of the disclosure, is intended to capture any molecule (small molecule, vitamin, mineral, protein, nucleic acid, lipid, fat, carbohydrate, etc.) produced by the microbe. Often, the exact mechanism of action, whereby a microbe of the disclosure imparts a beneficial trait upon a given plant species is not known. It is hypothesized, that in some instances, the microbe is producing a metabolite that is beneficial to the plant. Thus, in some aspects, a cell-free or inactivated preparation of microbes is beneficial to a plant, as the microbe does not have to be alive to impart a beneficial trait upon the given plant species, so long as the preparation includes a metabolite that was produced by said microbe and which is beneficial to a plant.

[0218] In one embodiment, the microbes of the disclosure may produce auxin (e.g., indole-3- acetic acid (IAA)). Production of auxin can be assayed. Many of the microbes described herein may be capable of producing the plant hormone auxin indole-3-acetic acid (IAA) when grown in culture. Auxin plays a key role in altering the physiology of the plant, including the extent of root growth.

[0219] Therefore, in an embodiment, the microbes of the disclosure are present as a population disposed on the surface or within a tissue of a given plant species. The microbes may produce a composition, such as a metabolite, in an amount effective to cause a detectable increase in the amount of composition that is found on or within the plant, when compared to a reference plant not treated with the microbes or cell-free or inactive preparations of the disclosure. The composition produced by said microbial population may be beneficial to the plant species.

[0220] Such microbial-produced compositions may be present in the cell culture broth or medium / a in which the microbes are grown, or may encompass an exudate produced by the microbes. As used herein, “exudate” refers to one or more compositions excreted by or extracted from one or more microbial cell(s). As used herein, “broth” refers to the collective composition of a cell culture medium after microbial cells are placed in the medium. The composition of the broth may change over time, during different phases of microbial growth and / or development. Broth and / or exudate may improve the traits of plants with which they become associated.Microbial-induced Traits in Plants

[0221] The present disclosure utilizes microbes to impart beneficial properties (or beneficial traits) to desirable plant species, such as agronomic species of interest. In the current disclosure, the terminology “beneficial property”, “beneficial trait”, or “trait of interest”, is used interchangeably and denotes that a desirable plant phenotypic or genetic property of interest is modulated, by the application of a microbe or microbial consortia as described herein. As aforementioned, in some aspects, it may very well be that a metabolite produced by a given microbe is ultimately responsible for modulating or imparling a beneficial trait to a given plant.

[0222] There are a vast number of beneficial traits that can be modulated by the application of microbes of the disclosure. For instance, the microbes may have the ability to impart one or more beneficial properties to a plant species, for example: increased growth, increased yield, increased nitrogen utilization efficiency, increased stress tolerance, increased drought tolerance, increased photosynthetic rate, enhanced water use efficiency, increased pathogen resistance, modifications to plant architecture that don’t necessarily impact plant yield, but rather address plant functionality, causing the plant to increase production of a metabolite of interest, etc.

[0223] In aspects, the microbes taught herein provide a wide range of agricultural applications, including: improvements in yield of grain, fruit, and Howers, improvements in growth of plant parts, improved ability to utilize nutrients (e.g., nitrogen, phosphate, and the like), improved resistance to disease, biopesticidal effects including improved resistance to fungi, insects, and / or nematodes; improved survivability in extreme climate, and improvements in other desired plant phenotypic characteristics.

[0224] In some aspects, the isolated microbes, consortia, and / or agricultural compositions of the disclosure can be applied to a plant, in order to modulate or alter a plant characteristic such as altered oil content, altered protein content, altered seed carbohydrate composition, altered seed oil composition, altered seed protein composition, chemical tolerance, cold tolerance, delayed senescence, disease resistance, drought tolerance, ear weight, growth improvement, health enhancement, heat tolerance, herbicide tolerance, herbivore resistance, improved nitrogen fixation, improved nitrogen utilization, improved nutrient utilization (e.g., phosphate, potassium, and the like), improved root architecture, improved water use efficiency, increased biomass, increased root length, increased seed weight, increased shoot length, increased yield, increased yield under water-limited conditions, kernel mass, kernel moisture content, metal tolerance,number of ears, number of kernels per ear, number of pods, nutrition enhancement, pathogen resistance, reduced pathogen levels (e.g., via the excretion of metabolites that impair pathogen survival), pest resistance, photosynthetic capability improvement, salinity tolerance, stay-green, vigor improvement, increased dry weight of mature seeds, increased fresh weight of mature seeds, increased number of mature seeds per plant, increased chlorophyll content, increased number of pods per plant, increased length of pods per plant, reduced number of wilted leaves per plant, reduced number of severely wilted leaves per plant, and increased number of nonwilted leaves per plant, a detectable modulation in the level of a metabolite, a detectable modulation in the level of a transcript, and a detectable modulation in the proteome relative to a reference plant.

[0225] In some aspects, the isolated microbes, consortia, and / or agricultural compositions of the disclosure can be applied to a plant, in order to modulate in a negative way, a particular plant characteristic. For example, in some aspects, the microbes of the disclosure are able to decrease a phenotypic trait of interest, as this functionality can be desirable in some applications. For instance, the microbes of the disclosure may possess the ability to decrease root growth or decrease root length. Or the microbes may possess the ability to decrease shoot growth or decrease the speed at which a plant grows, as these modulations of a plant trait could be desirable in certain applications.

[0226] In some embodiments, the isolated microbes, consortia, and / or agricultural compositions of the disclosure can be applied to a plant, in order to impart nematode stress tolerance to plants.

[0227] In some embodiments, the isolated microbes, consortia, and / or agricultural compositions of the disclosure can be applied to a plant, in order to provide bio stimulation (biostimulant effects) to plants. In some embodiments, the isolated microbes, consortia, and / or agricultural compositions of the disclosure can be applied to a plant, in order to provide disease tolerance to plants.Agricultural Compositions

[0228] In some embodiments, the microbes of the disclosure are combined with agricultural compositions. Agricultural compositions generally refer to organic and inorganic compounds that can include compositions that promote the cultivation of the microbe and / or the plant element; compositions involved in formulation of microbes for application to plant elements (for example, but not limited to: wetters, compatibilizing agents (also referred to as “compatibilityagents”), antifoam agents, cleaning agents, sequestering agents, drift reduction agents, neutralizing agents and buffers, corrosion inhibitors, dyes, odorants, spreading agents (also referred to as “spreaders”), penetration aids (also referred to as “penetrants”), sticking agents (also referred to as “stickers” or “binders”), dispersing agents, thickening agents (also referred to as “thickeners”), stabilizers, emulsifiers, freezing point depressants, antimicrobial agents, and the like); compositions involved in conferring protection to the plant element or plant (for example, but not limited to: pesticides, nematicides, fungicides, bactericides, herbicides, and the like); as well as other compositions that may be of interest for the particular’ application.

[0229] In some embodiments, the agricultural compositions of the present disclosure are solid. Where solid compositions are used, it may be desired to include one or more carrier materials with the active isolated microbe or consortia. In some embodiments, the present disclosure teaches the use of carriers including, but not limited to: mineral earths such as silicas, silica gels, silicates, talc, kaolin, attaclay, limestone, chalk, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, thiourea and urea, products of vegetable origin such as cereal meals, tree bark meal, wood meal and nutshell meal, cellulose powders, attapulgites, montmorillonites, mica, vermiculites, synthetic silicas and synthetic calcium silicates, or compositions of these.Growth Compositions

[0230] In some embodiments, a composition is provided to the microbe and / or the plant element that promotes the growth and development. Exemplary compositions include liquid (such as broth, media) and / or solid (such as soil, nutrients). Various organic or inorganic compounds may be added to the growth composition to facilitate the health of the microbe, alone or in combination with the plant element, for example but not limited to: amino acids, vitamins, minerals, carbohydrates, simple sugars, lipids.Formulation Compositions

[0231] One or more compositions, in addition to the microbe(s) or microbial-produced composition, may be combined for various application, stability, activity, and / or storage reasons. The additional compositions may be referred to as “formulation components”.

[0232] In some embodiments, the agricultural compositions disclosed herein may be formulated as a liquid, a solid, a gas, or a gel.

[0233] Thus in some embodiments, the present disclosure teaches that the agricultural compositions disclosed herein can include compounds or salts such as monocthanolaminc salt, sodium sulfate, potassium sulfate, sodium chloride, potassium chloride, sodium acetate, ammonium hydrogen sulfate, ammonium chloride, ammonium acetate, ammonium formate, ammonium oxalate, ammonium carbonate, ammonium hydrogen carbonate, ammonium thiosulfate, ammonium hydrogen diphosphate, ammonium dihydrogen monophosphate, ammonium sodium hydrogen phosphate, ammonium thiocyanate, ammonium sulfamate or ammonium carbamate.

[0234] In some embodiments, the present disclosure teaches that agricultural compositions can include binders such as: polyvinylpyrrolidone, polyvinyl alcohol, partially hydrolyzed polyvinyl acetate, carboxymethylcellulose, starch, vinylpyrrolidone / vinyl acetate copolymers and polyvinyl acetate, or compositions of these; lubricants such as magnesium stearate, sodium stearate, talc or polyethylene glycol, or compositions of these; antifoams such as silicone emulsions, long-chain alcohols, phosphoric esters, acetylene diols, fatty acids or organofluorine compounds, and complexing agents such as: salts of ethylenediaminetetraacetic acid (EDTA), salts of trinitrilotriacetic acid or salts of polyphosphoric acids, or compositions of these.

[0235] In some embodiments, the agricultural compositions comprise surface- active agents. In some embodiments, the surface-active agents are added to liquid agricultural compositions. In other embodiments, the surface-active agents are added to solid formulations, especially those designed to be diluted with a carrier before application. Thus, in some embodiments, the agricultural compositions comprise surfactants. Surfactants are sometimes used, either alone or with other additives, such as mineral or vegetable oils as adjuvants to spray-tank mixes to improve the biological performance of the microbes on the target. The types of surfactants used for bioenhancement depend generally on the nature and mode of action of the microbes. The surface-active agents can be anionic, cationic, or nonionic in character, and can be employed as emulsifying agents, wetting agents, suspending agents, or for other purposes. In some embodiments, the surfactants are non-ionics such as: alky ethoxylates, linear aliphatic alcohol ethoxylates, and aliphatic amine ethoxylates. Surfactants conventionally used in the art of formulation and which may also be used in the present formulations are described, in McCutcheon's Detergents and Emulsifiers Annual, MC Publishing Corp., Ridgewood, N.J., 1998, and in Encyclopedia of Surfactants, Vol. I-III, Chemical Publishing Co., New York, 1980-81 . In some embodiments, the present disclosure teaches the use of surfactants including alkali metal, alkaline earth metal or ammonium salts of aromatic sulfonic acids, for example, ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids of arylsulfonates, of alkyl ethers, of lauryl ethers, of fatty alcohol sulfates and of fatty alcohol glycol ether sulfates, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene or of the naphthalenesulfonic acids with phenol and formaldehyde, condensates of phenol or phenolsulfonic acid with formaldehyde, condensates of phenol with formaldehyde and sodium sulfite, polyoxyethylene octylphenyl ether, ethoxylated isooctyl-, octyl- or nonylphenol, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, ethoxylated castor oil, ethoxylated triarylphenols, salts of phosphated triarylphenolethoxylates, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin- sulfite waste liquors or methylcellulose, or compositions of these.

[0236] In some embodiments, the present disclosure teaches other suitable surface-active agents, including salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; alkylarylsulfonate salts, such as calcium dodecylbenzenesulfonate; alkylphenol-alkylene oxide addition products, such as nonylphenol-C18 ethoxylate; alcohol-alkylene oxide addition products, such as tridecyl alcohol-C16 ethoxylate; soaps, such as sodium stearate; alkylnaphthalene- sulfonate salts, such as sodium dibutyl-naphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2- ethylhexyl)sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryl trimethylammonium chloride; polyethylene glycol esters of fatty acids, such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; salts of mono and dialkyl phosphate esters; vegetable oils such as soybean oil, rapeseed / canola oil, olive oil, castor oil, sunflower seed oil, coconut oil, corn oil, cottonseed oil, linseed oil, palm oil, peanut oil, safflower oil, sesame oil, tung oil and the like; and esters of the above vegetable oils, particularly methyl esters.

[0237] In some embodiments, the agricultural compositions comprise wetting agents. A wetting agent is a substance that when added to a liquid increases the spreading or penetration power of the liquid by reducing the interfacial tension between the liquid and the surface on which it is spreading. Wetting agents are used for two main functions in agrochemical formulations: during processing and manufacture to increase the rate of wetting of powders in water to make concentrates for soluble liquids or suspension concentrates; and during mixing of a product withwater in a spray tank or other vessel to reduce the wetting time of wettable powders and to improve the penetration of water into watcr-dispcrsiblc granules. In some embodiments, examples of wetting agents used in the agricultural compositions of the present disclosure, including wettable powders, suspension concentrates, and water-dispersible granule formulations are: sodium lauryl sulphate; sodium dioctyl sulpho succinate; alkyl phenol ethoxylates; and aliphatic alcohol ethoxylates.

[0238] In some embodiments, the agricultural compositions of the present disclosure comprise dispersing agents. A dispersing agent is a substance which adsorbs onto the surface of particles and helps to preserve the state of dispersion of the particles and prevents them from reaggregating. In some embodiments, dispersing agents are added to agricultural compositions of the present disclosure to facilitate dispersion and suspension during manufacture, and to ensure the particles redisperse into water in a spray tank. In some embodiments, dispersing agents are used in wettable powders, suspension concentrates, and water-dispersible granules.Surfactants that are used as dispersing agents have the ability to adsorb strongly onto a particle surface and provide a charged or steric barrier to re-aggregation of particles. In some embodiments, the most commonly used surfactants are anionic, non-ionic, or mixtures of the two types.

[0239] In some embodiments, for wettable powder formulations, the most common dispersing agents are sodium lignosulphonates. In some embodiments, suspension concentrates provide very good adsorption and stabilization using poly electrolytes, such as sodium naphthalene sulphonate formaldehyde condensates. In some embodiments, tristyrylphenol ethoxylate phosphate esters are also used. In some embodiments, such as alkylarylethylene oxide condensates and EO-PO block copolymers are sometimes combined with anionics as dispersing agents for suspension concentrates.

[0240] In some embodiments, the agricultural compositions of the present disclosure comprise polymeric surfactants. In some embodiments, the polymeric surfactants have very long hydrophobic ‘backbones’ and a large number of ethylene oxide chains forming the ‘teeth’ of a ‘comb’ surfactant. In some embodiments, these high molecular weight polymers can give very good long-term stability to suspension concentrates, because the hydrophobic backbones have many anchoring points onto the particle surfaces. In some embodiments, examples of dispersing agents used in agricultural compositions of the present disclosure are: sodium lignosulphonates;sodium naphthalene sulphonate formaldehyde condensates; tri styrylphenol ethoxylate phosphate esters; aliphatic alcohol ethoxylates; alky ethoxylates; EO-PO block copolymers; and graft copolymers.

[0241] In some embodiments, the agricultural compositions of the present disclosure comprise emulsifying agents. An emulsifying agent is a substance, which stabilizes a suspension of droplets of one liquid phase in another liquid phase. Without the emulsifying agent the two liquids would separate into two immiscible liquid phases. In some embodiments, the most commonly used emulsifier blends include alkylphenol or aliphatic alcohol with 12 or more ethylene oxide units and the oil-soluble calcium salt of dodecylbenzene sulphonic acid. A range of hydrophile-lipophile balance (“HLB”) values from 8 to 18 will normally provide good stable emulsions. In some embodiments, emulsion stability can sometimes be improved by the addition of a small amount of an EO-PO block copolymer surfactant.

[0242] In some embodiments, the agricultural compositions of the present disclosure comprise solubilizing agents. A solubilizing agent is a surfactant, which will form micelles in water at concentrations above the critical micelle concentration. The micelles are then able to dissolve or solubilize water-insoluble materials inside the hydrophobic part of the micelle. The types of surfactants usually used for solubilization are non-ionics: sorbitan monooleates; sorbitan monooleate ethoxylates; and methyl oleate esters.

[0243] In some embodiments, the agricultural compositions of the present disclosure comprise organic solvents. Organic solvents are used mainly in the formulation of emulsifiable concentrates, ULV formulations, and to a lesser extent granular formulations. Sometimes mixtures of solvents are used. In some embodiments, the present disclosure teaches the use of solvents including aliphatic paraffinic oils such as kerosene or refined paraffins. In other embodiments, the present disclosure teaches the use of aromatic solvents such as xylene and higher molecular weight fractions of C9 and CIO aromatic solvents. In some embodiments, chlorinated hydrocarbons are useful as co-solvents to prevent crystallization of pesticides when the formulation is emulsified into water. Alcohols are sometimes used as co- solvents to increase solvent power.

[0244] In some embodiments, the agricultural compositions comprise gelling agents. Thickeners or gelling agents are used mainly in the formulation of suspension concentrates, emulsions, and suspoemulsions to modify the rheology or flow properties of the liquid and to prevent separationand settling of the dispersed particles or droplets. Thickening, gelling, and anti-settling agents generally fall into two categories, namely water-insoluble particulates and water-soluble polymers. It is possible to produce suspension concentrate formulations using clays and silicas. In some embodiments, the agricultural compositions comprise one or more thickeners including, but not limited to: montmorillonite, e.g., bentonite; magnesium aluminum silicate; and attapulgite. In some embodiments, the present disclosure teaches the use of polysaccharides as thickening agents. The types of polysaccharides most commonly used are natural extracts of seeds and seaweeds or synthetic derivatives of cellulose. Some embodiments utilize xanthan and some embodiments utilize cellulose. In some embodiments, the present disclosure teaches the use of thickening agents including, but are not limited to: guar gum; locust bean gum; carrageenan; alginates; methyl cellulose; sodium carboxymethyl cellulose (SCMC); hydroxyethyl cellulose (HEC). In some embodiments, the present disclosure teaches the use of other types of anti-settling agents such as modified starches, polyacrylates, polyvinyl alcohol, and polyethylene oxide. Another good anti-settling agent is xanthan gum.

[0245] In some embodiments, the presence of surfactants, which lower interfacial tension, can cause water-based formulations to foam during mixing operations in production and in application through a spray tank. Thus, in some embodiments, in order to reduce the tendency to foam, anti-foam agents are often added either during the production stage or before filling into bottles / spray tanks. Generally, there are two types of anti-foam agents, namely silicones and nonsilicones. Silicones are usually aqueous emulsions of dimethyl poly siloxane, while the nonsilicone anti-foam agents are water-insoluble oils, such as octanol and nonanol, or silica. In both cases, the function of the anti-foam agent is to displace the surfactant from the air-water interface.

[0246] In some embodiments, the agricultural compositions comprise a preservative.

[0247] In some embodiments, the agricultural compositions may be formulated as: a soil drench, a foliar spray, a dip treatment, an in-furrow treatment, a soil amendment, granules, a broadcast treatment, a post-harvest disease control treatment, or a seed treatment. In some embodiments, the agricultural compositions may be applied alone in or in rotation spray programs with other agricultural products.

[0248] In some embodiments, the agricultural compositions may be compatible with tank mixing. In some embodiments, the agricultural compositions may be compatible with tankmixing with other agricultural products. In some embodiments, the agricultural compositions may be compatible with equipment used for ground, aerial, and irrigation applications.

[0249] In some embodiments, the agricultural compositions may be applied to genetically modified seeds or plants.Protective Compositions

[0271] In some embodiments, the present invention teaches a synergistic use of the presently disclosed microbes or microbial consortia with plant growth regulators and / or stimulants such as phytohormones or chemicals that influence the production or disruption of plant growth regulators.

[0272] In some embodiments, the present invention teaches that phytohormones can include: Auxins (e.g., Indole acetic acid IAA), Gibberellins, Cytokinins (e.g., Kinetin), Abscisicacid, Ethylene (and its production as regulated by ACC synthase and disrupted by ACC deaminase).

[0273] In some embodiments, the individual microbes, or microbial consortia, or microbial communities, developed according to the disclosed methods can be combined with bio stimulants. Such biostimulants may be, but are not limited to, microbial organisms, plant extracts, seaweeds, acids, biochar, and the like.

[0274] In some embodiments, the individual microbes, or microbial consortia, or microbial communities, developed according to the disclosed methods can be combined with fertilizers, which may be organic (e.g., manure, blood, fish, and the like), nitrogen-based (e.g., nitrate, ammonium, urea, and the like), phosphate, and potassium. Such fertilizers may also contain micronutrients including, but not limited to, sulfur, iron, zinc, and the like.

[0275] In some embodiments, the present invention teaches additional plant- growth promoting chemicals that may act in synergy with the microbes and microbial consortia disclosed herein, such as: humic acids, fulvic acids, amino acids, polyphenols and protein hydrolysates.

[0276] Thus, in some embodiments, the disclosure provides for the application of the taught microbes in combination with Ascend® upon any crop. Further, the disclosure provides for the application of the taught microbes in combination with Ascend® upon any crop and utilizing any method or application rate.

[0277] In some embodiments, the present disclosure teaches agricultural compositions with biostimulants.

[0278] As used herein, the term “biostimulant” refers to any substance that acts to stimulate the growth of microorganisms that may be present in soil or other plant growing medium.

[0279] The level of microorganisms in the soil or growing medium is directly correlated to plant health. Microorganisms feed on biodegradable carbon sources, and therefore plant health is also correlated with the quantity of organic matter in the soil. While fertilizers provide nutrients to feed and grow plants, in some embodiments, biostimulants provide biodegradable carbon, e.g., molasses, carbohydrates, e.g., sugar's, to feed and grow microorganisms. Unless clearly stated otherwise, a biostimulant may comprise a single ingredient, or a combination of several different ingredients, capable of enhancing microbial activity or plant growth and development, due to the effect of one or more of the ingredients, either acting independently or in combination.

[0280] In some embodiments, biostimulants are compounds that produce non-nutritional plant growth responses. In some embodiments, many important benefits of biostimulants arc based on their ability to influence hormonal activity. Hormones in plants (phytohormones) are chemical messengers regulating normal plant development as well as responses to the environment. Root and shoot growth, as well as other growth responses are regulated by phytohormones. In some embodiments, compounds in biostimulants can alter the hormonal status of a plant and exert large influences over its growth and health. Thus, in some embodiments, the present disclosure teaches sea kelp, humic acids, fulvic acids, and B Vitamins as common components of biostimulants. In some embodiments, the biostimulants of the present disclosure enhance antioxidant activity, which increases the plant's defensive system. In some embodiments, vitamin C, vitamin E, and amino acids such as glycine arc antioxidants contained in biostimulants.

[0281] In other embodiments, biostimulants may act to stimulate the growth of microorganisms that are present in soil or other plant growing medium. Prior studies have shown that when certain biostimulants comprising specific organic seed extracts (e.g., soybean) were used in combination with a microbial inoculant, the biostimulants were capable of stimulating growth of microbes included in the microbial inoculant. Thus, in some embodiments, the present disclosure teaches one or more biostimulants that, when used with a microbial inoculant, is capable of enhancing the population of both native microbes and inoculant microbes. For a review of some popular uses of biostimulants, please see Calvo et al., 2014, Plant Soil 383:3-41.Combinations of Plant Elements, Microbes, and Agricultural Compositions

[0282] In some embodiments, the present disclosure teaches that the individual microbes, or microbial consortia, or microbial communities, or any combination of the preceding, for example comprising any one or a plurality of microorganisms that include a genome-edited Paenibacillus strain described herein, may be applied to a plant element, optionally in combination with any agricultural composition, for the improvement of a plant phenotype.

[0283] Isolated microbes or communities or consortia (generally “microbes” or “microbe”, interchangeably) may be applied to a heterologous plant element, creating a synthetic combination. Microbes are considered heterologous to a plant element if they are not normally associated with the plant element in nature, or if found, are applied in amounts different than that found in nature. In some embodiments, the microbes may be found naturally in one part of aplant but not another, and introduction of the microbes to another part of the plant is considered a heterologous association.

[0284] It is further contemplated that the microbe, either isolated or in combination with a plant or plant element, may be further associated with one or more agricultural compositions, such as those described above.

[0285] Synthetic combinations of microbes and plant elements, microbes and agricultural compositions, and microbes and plant elements and agricultural compositions are contemplated (generally “synthetic compositions”, compositions that comprise components not typically found associated in nature).Plant Element Treatments

[0286] In some embodiments, the present disclosure also concerns the discovery that treating plant elements before they are sown or planted with a combination of one or more of the microbes or agricultural compositions of the present disclosure can enhance a desired plant trait, e.g., plant growth, plant health, and / or plant resistance to pests.

[0287] Thus, in some embodiments, the present disclosure teaches the use of one or more of the microbes or microbial consortia as plant element treatments. The plant element treatment can be a plant element coating applied directly to an untreated and “naked” plant element. However, the plant element treatment can be a plant element overcoat that is applied to a plant element that has already been coated with one or more previous plant element coatings or plant element treatments. The previous plant element treatments may include one or more active compounds, either chemical or biological, and one or more inert ingredients.

[0288] The term “plant element treatment” generally refers to application of a material to a plant element prior to or during the time it is planted in soil. Plant element treatment with microbes, and other agricultural compositions of the present disclosure, has the advantages of delivering the treatments to the locus at which the plant elements are planted shortly before germination of the plant element and emergence of a plant element.

[0289] In other embodiments, the present disclosure also teaches that the use of plant element treatments minimizes the amount of microbe or agricultural composition that is required to successfully treat the plants, and further limits the amount of contact of workers with the microbes and compositions compared to application techniques such as spraying over soil or over emerging plant element.

[0290] Moreover, in some embodiments, the present disclosure teaches that the microbes disclosed herein arc important for enhancing the early stages of plant life (e.g., within the first thirty days following emergence of the plant element). Thus, in some embodiments, delivery of the microbes and / or compositions of the present disclosure as a plant element treatment places the microbe at the locus of action at a critical time for its activity.

[0291] In some embodiments, the microbial compositions of the present disclosure are formulated as a plant element treatment. In some embodiments, it is contemplated that the plant elements can be substantially unz / ormly coated with one or more layers of the microbes and / or agricultural compositions disclosed herein, using conventional methods of mixing, spraying, or a combination thereof through the use of treatment application equipment that is specifically designed and manufactured to accurately, safely, and efficiently apply plant element treatment products to plant elements. Such equipment uses various types of coating technology such as rotary coaters, drum coaters, fluidized bed techniques, spouted beds, rotary mists, or a combination thereof. Liquid plant element treatments such as those of the present disclosure can be applied via either a spinning “atomizer” disk or a spray nozzle, which evenly distributes the plant element treatment onto the plant element as it moves though the spray pattern. In aspects, the plant element is then mixed or tumbled for an additional period of time to achieve additional treatment distribution and drying.

[0292] The plant elements can be primed or unprimed before coating with the microbial compositions to increase the uniformity of germination and emergence. In an alternative embodiment, a dry powder formulation can be metered onto the moving plant element and allowed to mix until completely distributed.

[0293] In some embodiments, the plant elements have at least part of the surface area coated with a microbiological composition, according to the present disclosure. In some embodiments, a plant element coat comprising the microbial composition is applied directly to a naked plant element. In some embodiments, a plant element overcoat comprising the microbial composition is applied to a plant element that already has a plant element coat applied thereon. In some aspects, the plant element may have a plant element coat comprising, e.g., clothianidin and / or Bacillus firmus-L1582, upon which the present composition will be applied on top of, as a plant element overcoat. In some aspects, the taught microbial compositions are applied as a plant element overcoat to plant elements that have already been treated with PONCHO™ VOTiVO™.In some aspects, the plant element may have a plant element coat comprising, e.g., Metalaxyl, and / or clothianidin, and / or Bacillus firmus-I-1582, upon which the present composition will be applied on top of, as a plant element overcoat. In some aspects, the taught microbial compositions are applied as a plant element overcoat to plant elements that have already been treated with ACCELERON™.

[0294] In some embodiments, the microorganism-treated plant elements have a microbial spore concentration, or microbial cell concentration, from about: 10A2 to 10A12, 10A2 to 10A11 , 10A2 to 10 10, 10A2 to 10A9, lA02 to 10A8, 10A2 to 10A7, 10A2 to 10A6, 10A2 to 10A5, 10A2 to 10A4, or 10A2 to 10A3 per plant element.

[0296] In some embodiments, the microorganism-treated plant elements have a microbial spore concentration, or microbial cell concentration, from about: 10A4 to 10A12, 10A4 to 10Al 1, 10A4 to 10A10, 10A4 to 10A9, 10A4 to 10A8, 10A4 to 10A7, 10A4 to 10A6, or 10A4 to 10A5 per plant element.

[0297] In some embodiments, the microorganism-treated plant elements have a microbial spore concentration, or microbial cell concentration, from about: 10A5 to 10A12, 10A5 to 10Al 1, 10A5 to 10A10, 10A5 to 10A9, 10A5 to 10A8, 10A5 to 10A7, or 10A5 to 10A6 per plant element.

[0298] In some embodiments, the microorganism-treated plant elements have a microbial spore concentration, or microbial cell concentration, from about: 10A5 to 10A9 per plant element.

[0299] In some embodiments, the microorganism-treated plant elements have a microbial spore concentration, or microbial cell concentration, of at least about: 1 x 10A3, or 1 x 10A4, or 1 x 10A5, or 1 x 10A6, or 1 x 10A7, or 1 x 10A8, or 1 x 10A9 per plant element.

[0300] In some embodiments, the amount of one or more of the microbes and / or agricultural compositions applied to the plant element depend on the final formulation, as well as size or type of the plant or plant element utilized. In some embodiments, one or more of the microbes are present in about 2% w / w / to about 80% w / w of the entire formulation. In some embodiments, the one or more of the microbes employed in the compositions is about 5% w / w to about 65% w / w, or 10% w / w to about 60% w / w by weight of the entire formulation.

[0301] In some embodiments, the plant elements may also have more spores or microbial cells per plant clement, such as, for example about 10A2, 10A3, 10A4, 10A5, 10A6, 10A7, 10A8, 10A9, 10A10, 10Al l, 10A12, 10A13, 10A14, 10A15, 10A16, or 10A17 spores or cells per plant element.

[0304] In some embodiments, the plant element coats of the present disclosure can be at least 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15%, 15.5%, 16%, 16.5%, 17%, 17.5%, 18%, 18.5%, 19%, 19.5%, 20%, 20.5%, 21%, 21.5%, 22%, 22.5%, 23%, 23.5%, 24%, 24.5%, 25%, 25.5%, 26%, 26.5%, 27%, 27.5%, 28%, 28.5%, 29%, 29.5%, 30%, 30.5%, 31%, 31.5%, 32%, 32.5%, 33%, 33.5%, 34%, 34.5%, 35%, 35.5%, 36%, 36.5%, 37%, 37.5%, 38%, 38.5%, 39%, 39.5%, 40%, 40.5%, 41%, 41.5%, 42%, 42.5%, 43%, 43.5%, 44%, 44.5%, 45%, 45.5%, 46%, 46.5%, 47%, 47.5%, 48%, 48.5%, 49%, 49.5%, or 50% of the uncoated plant element weight.

[0305] In some embodiments, the microbial spores and / or cells can be coated freely onto the plant elements or they can be formulated in a liquid or solid composition before being coated onto the plant elements. For example, a solid composition comprising the microorganisms can be prepared by mixing a solid carrier with a suspension of the spores until the solid carriers are impregnated with the spore or cell suspension. This mixture can then be dried to obtain the desired particles.

[0306] In some other embodiments, it is contemplated that the solid or liquid microbial compositions of the present disclosure further contain functional agents e.g., activated carbon, nutrients (fertilizers), and other agents capable of improving the germination and quality of the products or a combination thereof.

[0307] Plant element coating methods and compositions that are known in the art can be particularly useful when they are modified by the addition of one of the embodiments of the present disclosure. Such coating methods and apparatus for their application are disclosed in, for example; U.S. Pat. Nos. 5,916,029; 5,918,413; 5,554,445; 5,389,399; 4,759,945; 4,465,017, and U.S. Pat. App. No. 13 / 260,310.

[0308] Plant element coating compositions are disclosed in, for example: U.S. Pat. Nos. 5,939,356; 5,876,739, 5,849,320; 5,791,084, 5,661,103; 5,580,544, 5,328,942; 4,735,015; 4,634,587; 4,372,080, 4,339,456; and 4,245,432.

[0309] In some embodiments, a variety of additives can be added to the plant element treatment formulations comprising the inventive compositions. Binders can be added and include those composed of an adhesive polymer that can be natural or synthetic without phytotoxic effect on the plant element to be coated. The binder may be selected from polyvinyl acetates; polyvinyl acetate copolymers; ethylene vinyl acetate (EVA) copolymers; polyvinyl alcohols; polyvinyl alcohol copolymers; celluloses, including ethylcelluloses, methylcelluloses, hydroxymethylcelluloses, hydroxypropylcelluloses and carboxymethylcellulose; polyvinylpyrolidones; polysaccharides, including starch, modified starch, dextrins, maltodextrins, alginate and chitosans; fats; oils; proteins, including gelatin and zeins; gum arabics; shellacs; vinylidene chloride and vinylidene chloride copolymers; calcium lignosulfonates; acrylic copolymers; polyvinylacrylates; polyethylene oxide; acrylamide polymers and copolymers; polyhydroxyethyl acrylate, methylacrylamide monomers; and poly chloroprene .

Other additives that can be added include trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

[0311] A polymer or other dust control agent can be applied to retain the treatment on the plant element surface.

[0312] In some specific embodiments, in addition to the microbial cells or spores, the coating can further comprise a layer of adherent. The adherent should be non-toxic, biodegradable, and adhesive. Examples of such materials include, but are not limited to, polyvinyl acetates; polyvinyl acetate copolymers; polyvinyl alcohols; polyvinyl alcohol copolymers; celluloses, such as methyl celluloses, hydroxymethyl celluloses, and hydroxymethyl propyl celluloses; dextrins; alginates; sugars; molasses; polyvinyl pyrrolidones; polysaccharides; proteins; fats; oils; gum arabics; gelatins; syrups; and starches. More examples can be found in, for example, U.S. Pat. NO 7,213,367.

[0313] Various additives, such as adherents, dispersants, surfactants, and nutrient and buffer ingredients, can also be included in the plant element treatment formulation. Other conventional plant element treatment additives include, but are not limited to: coating agents, wetting agents,buffering agents, and polysaccharides. At least one agriculturally acceptable carrier can be added to the plant element treatment formulation such as water, solids, or dry powders. The dry powders can be derived from a variety of materials such as calcium carbonate, gypsum, vermiculite, talc, humus, activated charcoal, and various phosphorous compounds.

[0314] In some embodiments, the plant element coating composition can comprise at least one filler, which is an organic or inorganic, natural or synthetic component with which the active components are combined to facilitate its application onto the plant element. In aspects, the filler is an inert solid such as clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers (for example ammonium salts), natural soil minerals, such as kaolins, clays, talc, lime, quartz, attapulgite, montmorillonite, bentonite or diatomaceous earths, or synthetic minerals, such as silica, alumina or silicates, in particular aluminum or magnesium silicates.

[0315] In some embodiments, the plant element treatment formulation may further include one or more of the following ingredients: other pesticides, including compounds that act only below the ground; fungicides, such as captan, thiram, metalaxyl, fludioxonil, oxadixyl, and isomers of each of those materials, and the like; herbicides, including compounds selected from glyphosate, carbamates, thiocarbamates, acetamides, triazines, dinitroanilines, glycerol ethers, pyridazinones, uracils, phenoxys, ureas, and benzoic acids; herbicidal safeners such as benzoxazine, benzhydryl derivatives, N,N-diallyl dichloroacetamide, various dihaloacyl, oxazolidinyl and thiazolidinyl compounds, ethanone, naphthalic anhydride compounds, and oxime derivatives; chemical fertilizers; biological fertilizers; and biocontrol agents such as other naturally-occurring or recombinant bacteria and fungi from the genera Rhizobium, Bacillus, Pseudomonas, Serratia, Trichoderma, Glomus, Gliocladium and mycorrhizal fungi. These ingredients may be added as a separate layer on the plant element, or alternatively may be added as part of the plant element coating composition of the disclosure.

[0316] In some embodiments, the formulation that is used to treat the plant element in the present disclosure can be in the form of a suspension; emulsion; slurry of particles in an aqueous medium (e.g., water); wettable powder; wettable granules (dry flowable); and dry granules. If formulated as a suspension or slurry, the concentration of the active ingredient in the formulation can be about 0.5% to about 99% by weight (w / w), or 5-40%, or as otherwise formulated by those skilled in the ail.

[0317] As mentioned above, other conventional inactive or inert ingredients can be incorporated into the formulation. Such inert ingredients include, but arc not limited to: conventional sticking agents; dispersing agents such as methylcellulose, for example, serve as combined dispersant / sticking agents for use in plant element treatments; polyvinyl alcohol; lecithin, polymeric dispersants (e.g., polyvinylpyrrolidone / vinyl acetate); thickeners (e.g., clay thickeners to improve viscosity and reduce settling of particle suspensions); emulsion stabilizers; surfactants; antifreeze compounds (e.g., urea), dyes, colorants, and the like. Further inert ingredients useful in the present disclosure can be found in McCutcheon’s, vol. 1, “Emulsifiers and Detergents,” MC Publishing Company, Glen Rock, N.J., U.S.A., 1996.

[0318] The plant element coating formulations of the present disclosure can be applied to plant elements by a variety of methods, including, but not limited to: mixing in a container (e.g., a bottle or bag), mechanical application, tumbling, spraying, and immersion. A variety of active or inert material can be used for contacting plant elements with microbial compositions according to the present disclosure.

[0319] In some embodiments, the amount of the microbes or agricultural composition that is used for the treatment of the plant element will vary depending upon the type of plant element and the type of active ingredients, but the treatment will comprise contacting the plant elements with an agriculturally effective amount of the inventive composition.

[0320] As discussed above, an effective amount means that amount of the inventive composition that is sufficient to affect beneficial or desired results. An effective amount can be administered in one or more administrations.

[0321] In some embodiments, in addition to the coating layer, the plant element may be treated with one or more of the following ingredients: other pesticides including fungicides and herbicides; herbicidal safeners; fertilizers and / or biocontrol agents. These ingredients may be added as a separate layer or alternatively may be added in the coating layer.

[0322] In some embodiments, the plant element coating formulations of the present disclosure may be applied to the plant elements using a variety of techniques and machines, such as fluidized bed techniques, the roller mill method, rotostatic plant element treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The plant elements may be presized before coating. After coating, the plant elements are typically dried and then transferred to a sizing machine for sizing. Such procedures are known in the art.

[0323] In some embodiments, the microorganism-treated plant elements may also be enveloped with a film overcoating to protect the coating. Such overcoatings arc known in the art and may be applied using fluidized bed and drum film coating techniques.

[0324] In other embodiments of the present disclosure, compositions according to the present disclosure can be introduced onto a plant element by use of solid matrix priming. For example, a quantity of an inventive composition can be mixed with a solid matrix material and then the plant element can be placed into contact with the solid matrix material for a period to allow the composition to be introduced to the plant element. The plant element can then optionally be separated from the solid matrix material and stored or used, or the mixture of solid matrix material plus plant element can be stored or planted directly. Solid matrix materials which are useful in the present disclosure include polyacrylamide, starch, clay, silica, alumina, soil, sand, polyurea, polyacrylate, or any other material capable of absorbing or adsorbing the inventive composition for a time and releasing that composition into or onto the plant element. It is useful to make sure that the inventive composition and the solid matrix material are compatible with each other. For example, the solid matrix material should be chosen so that it can release the composition at a reasonable rate, for example over a period of minutes, hours, or days.

[0325] In some embodiments, the present disclosure teaches that the individual microbes, or microbial consortia, or microbial communities, developed according to the disclosed methods can be combined with any plant biostimulant.

[0326] In some embodiments, the present disclosure teaches agricultural compositions comprising one or more commercially available biostimulants, including but not limited to: Vitazyme®, Diehard™ Biorush®, Diehard™ Biorush® Fe, Diehard™ Soluble Kelp, Diehard™ Humate SP, Phocon®, Foliar Plus™, Plant Plus™, Accomplish LM®, Titan®, Soil Builder™, Nutri Life, Soil Solution™, Seed Coat™, PercPlus™, Plant Power®, CropKarb®, Thrust™, Fast2Grow®, Baccarat®, and Potente® among others.

[0327] In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with an active chemical agent one witnesses an additive effect on a plant phenotypic trait of interest. In other embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with an active chemical agent one witness a synergistic effect on a plant phenotypic trait of interest.

[0328] In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a fertilizer one witnesses an additive effect on a plant phenotypic trait of interest. In other embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a fertilizer one witness a synergistic effect on a plant phenotypic trait of interest.

[0329] In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a plant growth regulator, one witnesses an additive effect on a plant phenotypic trait of interest. In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a plant growth regulator, one witnesses a synergistic effect. In some aspects, the microbes of the present disclosure are combined with Ascend® and a synergistic effect is observed for one or more phenotypic traits of interest.

[0330] In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a biostimulant, one witnesses an additive effect on a plant phenotypic trait of interest. In some embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a biostimulant, one witnesses a synergistic effect.

[0331] The synergistic effect obtained by the taught methods can be quantified according to Colby’s formula (i.e., (E) =X+Y-(X*Y / 100). See Colby, R. S., “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations,” 1967 Weeds, vol. 15, pp. 20-22. Thus, by “synergistic” is intended a component which, by virtue of its presence, increases the desired effect by more than an additive amount.

[0332] The isolated microbes and consortia of the present disclosure can synergistically increase the effectiveness of agricultural active compounds and also agricultural auxiliary compounds.

[0333] In other embodiments, when the microbe or microbial consortia identified according to the taught methods is combined with a fertilizer one witnesses a synergistic effect.

[0334] Furthermore, in certain embodiments, the disclosure utilizes synergistic interactions to define microbial consortia. That is, in certain aspects, the disclosure combines together certain isolated microbial species, which act synergistically, into consortia that impart a beneficial trait upon a plant, or which are correlated with increasing a beneficial plant trait.

[0335] The agricultural compositions developed according to the disclosure can be formulated with certain auxiliaries, in order to improve the activity of a known active agricultural compound. This has the advantage that the amounts of active ingredient in the formulation may be reduced while maintaining the efficacy of the active compound, thus allowing costs to be kept as low as possible and any official regulations to be followed. In individual cases, it may also possible to widen the spectrum of action of the active compound since plants, where the treatment with a particular active ingredient without addition was insufficiently successful, can indeed be treated successfully by the addition of certain auxiliaries along with the disclosed microbial isolates and consortia. Moreover, the performance of the active may be increased in individual cases by a suitable formulation when the environmental conditions are not favorable.

[0336] Such auxiliaries that can be used in an agricultural composition can be an adjuvant.Frequently, adjuvants take the form of surface-active or salt-like compounds. Depending on their mode of action, they can roughly be classified as modifiers, activators, fertilizers, pH buffers, and the like. Modifiers affect the wetting, sticking, and spreading properties of a formulation. Activators break up the waxy cuticle of the plant and improve the penetration of the active ingredient into the cuticle, both short-term (over minutes) and long-term (over hours). Fertilizers such as ammonium sulfate, ammonium nitrate or urea improve the absorption and solubility of the active ingredient and may reduce the antagonistic behavior of active ingredients. pH buffers are conventionally used for bringing the formulation to an optimal pH.

[0337] In some embodiments, the plant element is a plant reproductive element (e.g., seed, tuber, bulb, and / or shoot). In some embodiments, the plant element is other than a plant reproductive element (e.g., leaf, stem, and / or root). In some embodiments, a plurality of plant elements are associated with the microbe(s) described herein.

[0338] In some embodiments, the plant or plant element becomes associated with one or more microbes described herein via an indirect method, such as but not limited to treatment of the growth medium in which the plant or plant element is placed.

[0339] For further embodiments of agricultural compositions of the present disclosure, See “Chemistry and Technology of Agrochemical Formulations,” edited by D. A. Knowles, copyright 1998 by Kluwer Academic Publishers.Plants and Agronomic Benefits

[0412] While the invention has been particularly shown and described with reference to a preferred embodiment and various alternate embodiments, it will be understood by persons skilled in the relevant art that various changes in form and details can be made therein without departing from the spirit and scope of the invention. Various alterations, modifications, and improvements of the present disclosure that readily occur to those skilled in the art, including certain alterations, modifications, substitutions, and improvements are also part of this disclosure. For instance, while the particular examples below may illustrate the methods and embodiments described herein using a specific plant, the principles in these examples may be applied to any plant. Therefore, it will be appreciated that the scope of this invention is encompassed by the embodiments recited herein rather than solely by the specific examples that are exemplified below.

[0413] All cited publications, patents, patent applications, patent application publications, and non-patcnt literature referred to in this application arc herein incorporated by reference in their entirety, for all purposes, to the same extent as if each were individually and specifically incorporated by reference.EXAMPLES

[0414] The methods and compositions presented herein - based upon utilizing the disclosed isolated microbes, communities, consortia, and / or compositions comprising and / or produced by microbes or consortia or communities - improve one or more characteristics of plants, for example nitrogen fixation in agricultural crops. The abbreviation “uL” means “microliters”, “ug” means “micrograms”.Example 1: Microbe Culture and Sequencing

[0415] Paenibacillus strains were grown in culture media to obtain sufficient cellular' growth.

[0416] A subsample of each of the strains were then aseptically transferred to growth media and incubated under microaerophilic conditions for 72 hours.

[0417] Isolates of interest were grown to mid-log phase in R2A media. DNA was extracted with the Qiagen Powersoil DNA extraction kit and sequencing libraries were constructed with the Twist 96-Plex Library Prep Kit (formerly iGenomix RipTide kit) as per manufacturer instructions. Sequencing was performed on an Illumina HiSeq with PE150. Raw Illumina reads were trimmed, assembled, and annotated using the Bactopia nextflow pipeline with phiX removed, reads trimmed to Q20 and a minimal assembly of 3Mb. All assemblies passed through checkM for Quality control. Only assemblies with greater than 95% completeness and less than 5% contamination were used for this analysis. Taxonomy was assigned by GTDB-tk using default parameters with the April 2023 database (Pierre-Alain Chaumeil, Aaron J Mussig, Philip Hugenholtz, Donovan H Parks, GTDB-Tk: a toolkit to classify genomes with the Genome Taxonomy Database, Bioinformatics, Volume 36, Issue 6, 15 March 2020, Pages 1925-1927).

[0418] Bioinformatic analysis of nif gene clusters (components of the canonical nif operon), as well as upstream and downstream sequences, were performed to assess the presence of putative novel regulatory elements, including promoters. Phylogenetic analyses were performed to determine relative relationships between strains, species, and genera.Example 2: Novel Region Upstream (5’) from nifB and the GlnR binding site(s)

[0419] Results from promoter swaps prompted further examination of the known promoter driving expression of the nif cluster. A region of conserved sequence with high homology across multiple Paenibacillus species, upstream from nifB and the GlnR Binding Sites (FIG. 1), suggested other factors that may influence nitrogenase expression and / or activity.

[0420] Alignment of four Paenibacillus strains (8619, 77155, 103408, 17899) from three species (P. polymyxa, P. durus, P. odorifer) showed a high degree of conservation of a region that is 5’ distal to GlnR binding sites and nifB open reading frame (FIGs. 2 and 3), that appears to be A-T rich (indicated by the black box in FIG. 3).

[0421] A broader analysis of 154 strains revealed that there are similarities consistent with Subgroup designation. Subgroup I Paenibacillus, such as Paenibacillus polymyxa, comprise in this order: nifB, nifH, nifD, nifK nifE, nifN, nifX, hesA, nifV. Subgroup II Paenibacillus, such as Paenibacillus graminis, comprise in this order: nifB, nifH, nifD, nifK, nifE, nifN, nifX, orfl, hesA, niJV.

[0422] The upstream polynucleotide region of Subgroup I Paenibacillus are given as SEQID NOs. 1-57. The upstream polynucleotide region of Subgroup II Paenibacillus are given as SEQID NOs. 58-154. These sequences comprise polynucleotides that are upstream of the nifB coding region and GlnR Binding Site II, inclusive of GlnR Binding Site I. In some cases, the polynucleotide may further include a canonical Shine-Dalgamo sequence (e.g., AGGAGG) and / or an ATG start codon.

[0423] The Open Reading Frame (ORF) immediately 5’ adjacent to this region is variable among different species. For example, in Strains 8619 AND 77155 (P. polymyxa), the ORF runs in the same direction as the nif cluster. In Strains 17899 (P. odorifer), the ORF runs in the opposite direction as the nif cluster.

[0424] In Subgroup II strains, there appears to be a putative promoter immediately 5’ of the upstream region described herein e.g., some of the strains shown in FIG. 3).

[0425] The core motif sequences upstream of the GlnR Binding Site I and nifB, and downstream of the adjacent ORF, in several Paenibacillus strains are shown in Tables 2 & 3. Polynucleotides corresponding to these may be found in any Paenibacillus strain by bioinformatics methods known in the ail. Upstream sequences from other Paenibacillus strains, which comprise this motif, are given as SEQ ID Nos. 1-154. The motif may be found on either strand.Table 2: Example Paenibacillus “Upstream” core motif sequencesTable 3: Motifs in selected Paenibacillus strains

[0426] The core consensus sequence for this motif is xTxTC, wherein x represents any nucleotide. The length of the motif is approximately 6- 16 nucleotides. Two main variants of the motif were identified (one comprising ATTTCC, the other comprising GTCTC), both comprising the core motif of xTxTC.Example 3: Editing of Paenibacillus strains

[0427] Edits of Paenibacillus microbes to produce engineered strains that impart improved characteristics to plants with which they are associated may be accomplished by nucleotide insertion, nucleotide deletion, nucleotide replacement, and / or any combination or plurality of the preceding. The net effect may be one of upregulation, downregulation, knockout (of the target polynucleotide and / or the function of its encoded RNA or protein), and / or any combination or plurality of the preceding.

[0428] Because of the known challenges of working with Gram Positive bacteria such as Paenibacillus, as compared to more amenable gram-negative bacteria such as Klebsiella, successful edits and successful associations with plants that impart improved benefits to the plants are surprising and unexpected.

[0429] The gram-positive gene editing vector pMiniMad2 was obtained from the B cillus Genetic Stock Center, and modified by the insertion of the TraJ origin of transfer, originally from vector pKVM4, between the Sall and BamHl restriction sites, yielding the mobilizable Gram-Positive gene editing vector pMMmob.Assembly of Editing Vectors

[0430] Polymerase Chain Reaction (PCR) was run using the appropriate primers with Q5 high- fidelity polymerase to amplify the upstream and downstream homology arms with the appropriate Gibson assembly overhangs from purified genomic DNA from the target strain. The PCR products were run on an agarose gel to confirm the appropriate size. The bands were excised and purified from the gel.

[0431] The backbone vector pMMmob was digested with the restriction enzymes EcoRI and BamHI for at least 30 minutes at 37C in Cutsmart buffer. The digest was run on an agarose gel to confirm the appropriate size. The digested backbone was purified from the gel.

[0432] Gibson assembly was performed by combining approximately lOOng of digested pMMmob with the insert fragments in a 1:3:3 backbone:insert:insert molar ratio in a lOul volume, then adding lOul 2x Gibson Reagent. The reaction was incubated at 50C for 60 minutes then used for transformation into E. coli DH5a.

[0433] l-5ul of the Gibson assembly mixture was added to 50ul of freshly thawed, chemically competent E. coli DH5a cells and finger vortexed. The cell-plasmid mixture was incubated on ice for 30 minutes, heat shocked at 42C for 30 seconds, then moved back to ice for a further 5 minutes. ImL SOC (Super-Optimal Catabolism) medium was added, and the cells were incubated at 37C with 200RPM shaking for 60-90 minutes for recovery. Dilutions of the recovery culture were plated onto LB agar plates supplemented with lOOng / uL Ampicillin and incubated overnight at 37C.

[0434] The plasmid region comprising the assembled inserts was amplified from several recovered colonies via colony PCR using GoTaq polymerase, and the PCR products were run on an agarose gel to confirm the expected sized product. Appropriately-sized PCR products were sent for Sanger sequencing to confirm proper assembly and lack of any off-target mutations in the editing cassette.

[0435] Colonies confirmed to harbor the correct plasmid were inoculated into LB broth supplemented with lOOng / uL Ampicillin and grown overnight at 37C and 200RPM shaking. The plasmid was purified from the overnight culture and transformed into conjugation donor strain E. coli BW29472 via electroporation.

[0436] lul of the purified plasmid was combined with 50ul of freshly thawed E. coli BW29472 electrocompetent cells and incubated for 5 minutes on ice. The cell-plasmid mixture wastransferred into a pre-chilled 1mm electroporation cuvette on ice. Using an electroporator, a 1800V, 25uF, 200Q charge as applied to the cuvette, and the sample was immediately resuspended in ImL SOC medium supplemented with 0.3mM 2,6-diaminopimelic acid (DAP). The resuspended cells were incubated at 37C with 200RPM shaking for 60-90 minutes for recovery. Dilutions of the recovery culture were plated onto LB agar plates supplemented with lOOng / uL Ampicillin and 0.3mM 2,6-diaminopimelic acid and incubated overnight at 37C. Recovered transformants were used as donor strains for conjugation.Conjugation

[0437] Recipient strains were inoculated into 5mL Tryptic Soy Broth (TSB) medium in 50mL conical tubes and grown overnight at 30C and 200RPM shaking. Donor E. coli BW29427 harboring the plasmid to be mobilized was inoculated into 5mL LB medium supplemented with lOOug / uL Ampicillin and 0.3mM 2,6-diaminopimelic acid (DAP) and grown overnight at 37C and 200RPM shaking.

[0438] 1ml aliquots of the overnight donor and recipient cultures were spun down, washed in sterile water, combined and spotted onto the surface of LB agar plates supplemented with 0.3mM DAP for conjugative mating. Mating plates were incubated overnight at 25C, the permissive temperature for replication of pMMmob in Gram-Positive recipient strains.

[0439] Mating mixtures were resuspended by the addition of 1ml sterile water over the top of the spot and agitation with a sterile L-spreader. Resuspensions were collected in microcentrifuge tubes, washed, and resuspended in lOOul of sterile water. The concentrated cells were spread over TSA plates supplemented with MLS (25ug / ml Lincomycin, lug / ml Erythromycin) with no DAP added and incubated for 48-72 hours at 25C until the appearance of transconjugant colonies.Plasmid Integration

[0440] Recovered transconjugants were inoculated into 5mL TSB medium supplemented with MLS and grown for 48 hours at 25C with 200RMP shaking, or until turbid. Dilutions of the culture were plated onto TSA + MLS plates and incubated overnight at 37C, the restrictive temperature for plasmid replication, until the appearance of integrated colonies.Plasmid Excision

[0441] Integrated colonies were inoculated into 5mL TSB medium supplemented with MLS and incubated overnight at 37C with 200RPM shaking. 5ul of the overnight culture was diluted into5mL fresh TSB medium without antibiotics and grown overnight at 25C, 200RPM shaking. Subculturing of 5ul overnight culture into 5mL fresh TSB qt25C, 200RPM shaking was repeated twice, for a total of three rounds of subculturing. Dilutions of the round three overnight culture were plated onto R2A plates lacking antibiotics and incubated at 30C overnight.

[0442] Excision of the plasmid was confirmed by picking individual colonies from the R2A plate and re -plating them in a grid format onto agar plates with and without MLS. Both plates were incubated at 30C for 24-48 hours, until the appearance of colonies. Colonies that grew when plated onto the plate without MLS, but not on the plate containing MLS, we confirmed to have excised and lost the plasmid.Confirmation of editing

[0443] The edit region was amplified from putative edited strains via colony PCR, and the presence of the proper edit was confirmed by the size of the band when run on an agarose gel (when possible), and / or by sanger sequencing. The absence of the plasmid backbone was confirmed by PCR assaying of the MLS resistance cassette. Colonies yielding a band for the MLS cassette were confirmed to not be proper edits.

[0444] Sequence results were analyzed to differentiate colonies that had excised to wild type from properly edited colonies, and the sequences were checked for off-target mutations.Other Methods

[0445] Alternatively, any other method known in the ail may be employed to effect any one or more of the polynucleotide edits described herein, for example but not limited to: targeting and / or homing nucleases, restriction endonucleases, zinc finger nucleases, meganucleases, Cas endonucleases, TAL effector nucleases, guided nucleases, random site mutations, blind editing (WO2023039463 published 16 March 2023), chemical mutagenesis, or radiation mutagenesis. Generally, a double-strand break is created at or near the target site to be edited, which is repaired by intracellular processes such as non-homologous end joining, homologous recombination, or homology-directed repair. The net effect can be any one or more of the following: insertion of at least one nucleotide, deletion of at least one nucleotide, replacement of at least one nucleotide, chemical alteration of at least one nucleotide. For the purposes of the edits of Paenibacillus strains described herein, any technique that is desired by the practitioner may be used to achieve the end result.Example 4: Polynucleotide Editing and Targets

[0446] To assess the function of the upstream regions described herein, various deletions were introduced into the genome of different species and strains of Paenbacillus, as shown in FIG. 4 and described in Tables 4-6. The edits were created by either a targeted homologous recombination method or by blind editing (WO2023039463 published 16 March 2023), into either a wild-type parental strain or a previously-edited strain, as described.

[0447] The sequences that were deleted in the exemplary strains are given in Table 4 as SEQID NOs. 155-158. The Delta-95 (A95) mutation is a deletion of 94 nucleotides. The Delta- 105 (A105) mutation in P. odorifer is a deletion of 105 nucleotides which are located in a similar position to the Delta-95 fragment in P. polymyxa. Both the Delta-95 and Delta- 105 fragments are upstream from and distal to the nifB coding sequence. The Delta- 150 (A150) mutation is a deletion of 149 nucleotides adjacent to and downstream from A105.

[0448] Some of the deletion mutations were also stacked with other types of mutations, as described herein. The methods and compositions for the previously-edited parental strains are described in W02022204062 published 29 September 2022, PCT / US2023 / 074808 filed 21 September 2023, and WO2023225117 published 23 November 2023.Table 4: Paenibacillus Parental StrainsTable 5: EditsTable 6: Deleted sequences in exemplary strainsGlnR knockout

[0449] GlnR is the primary known regulator of nif expression in Paenibacillus, and its interaction with glutamine synthase is how the cell regulates Nif expression based on the level of nitrogen in the environment. By removing this regulator, Nif expression becomes unregulated relative to the level of environmental nitrogen and may instead be driven by unknown transcription factors not regulated by nitrogen level. This may result in an increase in nif expression, particularly under nitrogen excess conditions.

[0450] The editing cassette was constructed by inserting the native genomic sequence approximately 700 basepairs upstream of and not including the start codon of the glnR open reading frame was assembled with the native genomic sequence 700 basepairs downstream of and including the stop codon of the glnR open reading frame.GlnR C25 truncation

[0451] The alpha helix C25 region if GlnR folds back on the dimerization site, causing GlnR to primarily exist as monomers in the cell. It is not until the feedback inhibited glutamine synthase (FBI-GS) interacts with the GlnR monomers under nitrogen excess conditions, that the C- terminal region is folded away to encourage dimerization. GlnR dimers are then able to tightly bind to binding Site II for tight repression of nif expression. By removing the C-terminal 25 amino acids, this regulatory interaction is disrupted, preventing GlnR dimerization and binding from being governed by nitrogen levels. This would allow for increased nif expression under excess nitrogen conditions.

[0452] The editing cassette was constructed by inserting the native genomic sequence approximately 500-1300 (depending on the strain) basepairs upstream of and not including the codon twenty five positions from the C-terminus of the glnR open reading frame was assembled with the native genomic sequence 500-900 (depending on the strain) basepairs downstream of and including the stop codon of the glnR open reading frame.GlnR Binding Site II duplication

[0453] This replacement of the native Site I sequence with the native Site II sequence is intended to increase nif expression increasing the binding affinity of the GlnR to the region responsible for activating nif expression. Under all conditions, GlnR has a higher binding affinity to the Site II sequence. Since the activation vs repression activity of GlnR seems to be dependent on the location of binding, having an increased binding affinity for the location responsible for activation resulted in increased nif expression.

[0454] The editing cassette was constructed by inserting the native GlnR binding Site II sequence between the native genomic sequence approximately 1000 basepairs upstream from and not including the first nucleotide of GlnR binding Site I, and the native genomic sequence approximately 1000 base pairs downstream of and not including the final basepair of GlnR binding Site I.GlnR Binding Site II inactivation and duplication

[0455] These edits are expected to work synergistically together by preventing GlnR dimers from binding to the Site II “off switch” and enhancing the “on switch” by increasing its binding efficiency. These edits together ensure that GlnR can only act as a strong positive influence of nif operon gene transcription.

[0456] The editing cassette was constructed by inserting the native GlnR binding Site II sequence between the genomic sequence of a strain previously edited with a GlnR binding Site II inactivation approximately 1000 basepairs upstream from and not including the first nucleotide of GlnR binding Site I, and the genomic sequence of a strain previously edited with a GlnR binding Site II inactivation approximately 1000 base pairs downstream of and not including the final basepair of GlnR binding Site I.GlnR C25 frame shift truncation and glnA SNP

[0457] A 76-nucleotide sequence between and not including nucleotide A332 and T409 of the glnR gene was deleted, resulting in the disruption of the native stop codon, and a frame shift mutation. The frame shift mutation results in the addition of 13 amino acids onto the GlnR protein before reaching a stop mutation. Concurrently, a single nucleotide in the neighboring glnA gene was altered. Nucleotide C164 was changed to an A, resulting in a Serine to Tyrosine mutation at amino acid position 55 of the GlnA protein.

[0458] Intending to design an editing cassette that would delete the last 25 amino acids, primers were designed with intention to amplify nucleotide arms approximately 500 nucleotides upstream of and including G333 and approximately 500 nucleotides downstream of and including T409 of glnR in Paenibacillus odorifer CM 17899, resulting in a clean 75 nucleotide deletion from the glnR gene and 25 amino acid deletion from the GlnR protein, with the native stop codon preserved. An error was made in the primer design, such that the upstream homology region instead extended from and including A332. This error resulted in an editing cassette that delivers a 76 nucleotide deletion, disrupting the native stop codon and causing a frame shift mutation.

[0459] During the construction of the editing cassette, a single nucleotide polymorphism (SNP) was introduced during the polymerase chain reaction (PCR) to amplify the downstream homology arm in the glnA gene. This SNP may have been introduced by a random error from the Q5 high fidelity polymerase used in the PCR reaction or by an SNP present in a copy of the P. polymyxa CM17899 genomic DNA used in the reaction. This nucleotide change was undirected and not based off known variation in the GlnA gene of Paenibacillus spp. During the integration and excision of the editing plasmid into P. polymyxa CM17899, this off-target modification was left in the resulting homology region. These edits provided surprisingly positive results for plants associated with the edited microbes.nzf PLH77 Promoter Insertion

[0460] The promoter PLH-77 was operably linked with the nif cluster of the target strain by inserting the promoter sequence upstream of the putative native ribosome binding site (RBS) without removing any of the native promoter sequence.

[0461] Using standard molecular cloning techniques and Gibson assembly, an editing cassette was assembled in which homology arms comprising the native sequences approximately 1000 nucleic acids upstream and downstream of the targeted promoter site were assembled into a scarless homologous recombination vector with the synthesized promoter sequence seamless assembled between them. The resulting editing vector was delivered, and the resulting transformant was cultured in a manner sufficient to induce the integration of the whole plasmid, and later excision of the unwanted genetic material, leaving only the desired edit. Sanger sequencing of the editing region confirmed the presence of the desired modification.A47.1

[0462] To delete the first 47 base pairs of the DNA fragment comprising the motif upstream from the nifB coding sequence, up- and downstream homology arms (~1 kilobase) were generated via polymerase chain reaction (PCR) with genomic DNA as template and appropriate primers. DNA fragments were purified from gel slices or PCR reactions and quantified by Nanodrop spectrophotometry. Homology arm fragments and editing vector were combined in proper ratio and assembled via Gibson Assembly. Editing vectors were sequenced via Oxford Nanopore sequencing to ensure there were no errors and were transformed into E. coli BW29427. The E. coli strain was used as donor to transfer editing vector into Paenibacillus for selection. Edits were installed in the chromosome via homologous recombination and proper edits were identified by screening with PCR. Genomes of edited strains were sequenced to ensure the proper edit was selected and off-target mutations were absent.A47.2To delete the second 47 base pairs of the DNA fragment comprising the motif upstream from the nifB coding sequence, up- and downstream homology arms (~1 kilobase) were generated via polymerase chain reaction (PCR) with genomic DNA as template and appropriate primers.

[0467] Sequencing preparation for microbe identification, and long-term storage, is performed by the following method:Day 1:

[0468] Use a 10 uL sterile tip to transfer a colony from a plate to a flask containing an appropriate liquid growth medium. Place the isolates on a shaker at room temperature and incubate for 2 days.Day 3:

[0469] Tubes may be cloudy after being on the shaker for 2 days. All samples are analyzed by PCR. Vortex each tube, collect a 50 uL sample from each vortexed tube, and dispense in a 96- well plate. Using a multichannel pipette, dispense 15 uL of the 50 uL samples into a new 96-well plate. The 96-well plate containing 35 uL of each sample will be used for phenotyping, and the 96-well plate containing 15 uL of each sample will be used for PCR analysis. 27F / 1492R primers are generally used for 16S PCR analysis, as they yield better results than PB36 / 38. Appropriate negative controls should be included with the plate and analyzed by PCR. The plate will be analyzed by PCR using an Eppendorf thermocycler. Once the PCR is finished, run a gel using standard gel electrophoresis techniques. This is important because most isolates are grown enough where they should ideally be put into long-term storage on day 3. The PCR and gel electrophoresis analysis are used to confirm that the isolates contain bacteria, rather than other microbes. For isolates that do not pass PCR or have clear broth, vortex tubes and use a loop to streak out onto a petri plate. Check after several days to see if anything grows, or if the tube is contaminated. For isolates that pass PCR, dispense 600 uU of 50% glycerol into a 2 ml screw cap tubes and add 1200 uU of the bacterial culture, such that the broth is stored in 20% glycerol. Store the glycerol stock at -80 °C and record an image of the gel of the PCR samples. Day 4:

[0470] Check the petri plates of the streaked isolates that failed PCR for growth. (During this time, the 2 ml broth tubes will remain on the shaker.) Once there is growth on the plate and the colonies appear to have been successfully isolated, dispense 600 uU of the broth-glycerol mixture in the small tube, and put both tubes in their respective -80 boxes. It is possible for isolates to fail the PCR check because of any of the following reasons: the primers may not work on all bacteria, the isolate is actually a fungus, the isolate is very adherent and therefore does not homogenize in the broth, the isolate produces too much EPS therefore needs dilution prior to PCR set-up, or the isolate is a slow grower. Over the next few days, continue checking the plate to confirm that only a single bacterial species was isolated. If contamination is observed, prepare a new isolate. Viability of the prepared glycerol stocks should be verified.Example 6: Formulation of Microbes

[0471] Microbes identified according to the previous examples may be formulated with additional components for application via methods such as, but not be limited to: seed treatment, root drench, root wash, seedling soak, foliar application, soil inocula, in-furrow application, sidedress application, soil pre-treatment, wound inoculation, drip tape irrigation, vectormediation via a pollinator, injection, osmopriming, hydroponics, aquaponics, aeroponics. The formulation comprising the microbes are prepared for agricultural application as a liquid, a solid, or a gas formulation. Application to the plant is achieved, for example, as a powder for surface deposition onto plant leaves, as a spray to the whole plant or selected plant element, as part of a drip to the soil or the roots, or as a coating onto the plant element prior to planting. Such examples are meant to be illustrative and not limiting to the scope of the invention.

[0472] Media components for an exemplary microbe preparation are shown below in Tables 7a- 7d. Add all contents with 50% of the final volume of water needed, and stir the solution at an elevated temperature until dissolved. After all contents have been dissolved, use sterile RO water to bring the solution to the final desired volume. Field trial preparations are typically performed using the 4x formulation.Table 7a: Exemplary media components and concentrations for microbe formulationTable 7b: Exemplary media components for microbe formulationTable 7c: Exemplary media components for microbe formulationTable 7d: Exemplary media components for microbe formulation

[0473] The procedure to mix TIX formulation is as follows: Measure all dry ingredients into a 50ml tube. Vortex the ingredients well to ensure xanthan gum is “separated” through the other carbon sources. Add about half of total sterile RO water to the mix, vortex. Use the long end of an L-spreader to break up chunks as much as you can. Heat some sterile RO water in the microwave to warm water bath temperature (45-50°C). Add the remaining sterile RO water to the mix, vortex. Repeat step 4 and vortex as needed until you have a clear solution with no lumps. Spin down the bubbles created in the process of mixing by using a centrifuge for 5-10 seconds on “fast spin”. Remember to have a balance to counter the formulation (TIX) tube. Allow formulation to cool to room temperature. 1. Mix in the microbial consortia. Vortex to ensure homogeneity. It is ideal to add microbes at a concentration of 10A9 CFU / ml to the formulation.

[0474] Apply the formulation to the plant or plant element for testing in field trial.Example 7: Application of Microbes to Plant Elements and Cultivation Thereof

[0475] A microbial composition (comprising one or more isolated microbes of a single strain, a consortium, a community, a combination, or any combination of the preceding) is prepared according to the previous Examples. The microbial composition comprises one or more microbes, optionally in combination with one or more additional microbes disclosed herein.Microbial Compositions for Application

[0476] In some methods, the microbial composition is dried and applied directly to a plant element.

[0477] In some methods, the microbial composition is suspended in a liquid formulation for application to a plant element.

[0478] In some methods, the microbial composition is combined with another composition, such as but not limited to: a carrier, a wetting agent, a stabilizer, a salt. In some methods, the other composition comprises a molecule that introduces additional agriculturally -beneficial outcomes to the plant to which the microbial composition is applied. The other composition includes, for example but not limited to: an herbicide, a fungicide, a bactericide, a pesticide, an insecticide, a nematicide, a biostimulant.Application Types

[0479] The microbial composition is applied to a plant element, at a time during development appropriate to the desired outcome, for example: in a formulation of a pre-planting soil drench / in-furrow application; as a seed or other reproductive element treatment; as a postplanting reproductive element application; as an in-furrow, drip, or drench application after planting; as a direct application to a plant element (e.g., root, leaf, stem); as an application to a harvested plant element e.g., a fruit or a grain). Combinations of application types are also tested.Application Methods

[0480] The microbial composition is applied to (inoculating) a plant or plant element or plant product (pre-planting, post planting, pre-harvest, or post-harvest). This can be accomplished, for example, by applying the agricultural composition to a hopper or spreader or tank, which contains the microbial composition and which is configured to broadcast the same.

[0481] A seed coating of the microbial composition is applied to one or more seeds of a crop plant. Upon applying the isolated microbe as a seed coating, the seed is planted and cultivated according to practices established for that crop.

[0482] Alternatively, the microbial composition is applied to the soil for the benefit of a plant existing in that soil. Methods of soil application include in-furrow treatment, drench, and drip applications.

[0483] Alternatively, the microbial composition is applied to the surface of a plant or plant part after germination.

[0484] Alternatively, the microbial composition is applied to material obtained from the plant after harvest.

[0485] A control plot of plants, which did not have the isolated microbe applied, are also planted. Plants associated with the microbial composition exhibit improved characteristics of interest.

[0486] Application methods may be performed according to any protocol known in the art.

[0487] Plant elements, plants, or growth medium (e.g., soil) may further be inoculated with a disease or pest, according to the purpose of the test.

[0488] An exemplary, non-limiting protocol for drenching tomato plants is given below:1. Ten days after planting carefully separate plants out into 6 reps for each treatment. Plants are delicate and leaves can tear easily. Ensure that the size and overall appearance of plants is as uniform as possible (The purpose of thinning is continuing with an homogenous plant population). Transplant if there are not enough plants per reps. See step 3 for guidelines on transplanting.2. Begin thinning pots down to one plant per pot. Remove the smaller plant, one that is unhealthy or deformed in some way. If there are 2 or more healthy plants per pot, the extras can be transplanted into another pot. Use leftover soil prepped from initial planting or from pots where seeds did not germinate.3. To transplant: If some pots didn’t germinate, they can be filled with a plant from another container. To do this simply scoop out the extra plant (trying to scoop out as much root mass as possible without disturbing the other plant) with a scoopula and place into a hole made in the empty pot. Firm the soil around the plant with slight finger pressure.4. Space out the pots into 6 pot lines (1 line of pots per treatment), will take 4 RL98 trays. Once done, have a look at all the treatments and consider making some pot switches to ensure some treatments don’t have all large plants and others have all large plants.5. Change gloves if necessary. Label each pot with your pre-prepared Avery Labels. Treatments should be labeled into rows of 6 replicates i.e., 1-1, 1-2, 1-3 to 1-6, etc. Makes it easier to find all replicates for each treatment6. Two weeks after planting (roughly 4 days after thinning and labeling), obtain treatments from the Microbiology team; set on the table with trays of prepped plants. Gather combitips, repeater, and RO water, (note: Plants should be watered lightly the day of treatment)7. Mix microbial solution by inverting tube / container (microbial treatment) 2-3 times or give a light shake. Set combitip to dispense 2ml. Collect treatment fluid into combitip, dispense first step back into the tube. Ensure the treatment you have corresponds to the row of plants to be treated. Once confirmed, gently dispense 2ml of treatment onto the surface soil of each pot, close to the stem but avoid direct contact with the stem and leaves.8. Dispose of combitip and repeat step 6 for all treatments. For the inoculated control (IC or InoCon) and untreated control (UTC), apply RO water in place of a treatment.Once all treatments have been applied, place plants back into growth chamber for (optional inoculation), growth, evaluation.Visualization of Microbes Associated with Plant Elements

[0489] Individual microbes can be tagged with a fluorescent protein according to methods known in the art. Microscopic image analysis demonstrated that the microbes disclosed herein were found associated with various plant tissues.Example 8: in vitro Testing

[0490] Wild Type and Genome-edited strains are assessed for root colonization, acetylene reduction activity, biofilm formation, turbidity (OD at 600 nm), oxygen tolerance, and gene expression. Unless otherwise specified, protocols are conducted using methods known in the art. ARA with GC-FID for Gram Positive Strains

[0491] Ensure all equipment and materials are sterilized. Wrap sealing equipment containers in foil prior to autoclaving so that they can be unwrapped in the Anaerobic chamber pass box and enter the Anaerobic chamber sterile. Seal vial openings with foil prior to sterilizing. Loose ‘seals’ are required to allow gas exchange in the pass box.1. Inoculate isolates from -80 C into broth culture and incubate at 30 C overnight.2. Cells from overnight cultures are harvested by centrifugation and washed in NF11 media.3. Washed cell suspension density (OD600) was measured by spectrophotometry.4. Prepare the Anaerobic chamber by cleaning the surfaces and passing the sealing equipment through - ensure containers allow for gas exchange.5. Add 30 mL NF11 1 vial - 2 reps / isolate.6. Cultures are inoculated to OD600 -0.05.7. Pass vials through Anaerobic chamber and seal under anaerobic conditions with and without Nitrogen - include an empty vial (with foil ‘cap’) to add an anaerobic indicator for QC purposes.8. Place vials in 30 C, 200 rpm for 5 hours.9. After 5 hours, working in the fume hood, remove 10% (4 mL) from the headspace of each vial and replace with the same volume of acetylene gas. NOTE: Acetylene gas is highly reactive and explosive thus the bag must be kept in the fume hood while working.10. Incubate at 30 C, 200 rpm for 48 hrs.11. At 48 hours (or other known timepoint), take 1 mL headspace sample and place into a GC collection tube.12. Run samples in GC using instrument method for ethylene analysis ‘split 4’ which measures acetylene peak and ethylene people13. Amount of gas is quantified by peak area.14. Take OD600 readings of 200ul of the culture and TVCs of culture.15. Analyze ethylene gas as a percentage conversion of acetylene to ethylene. This produces an estimate of total conversion.

[0492] The volume of gas produced (ethylene) can either be quantified using calibration points in Chromeleon or by calculation from the % peak area. Acetylene + Ethylene peak area % must = 100% for this. From the knows amount of Acetylene added, the ethylene produced can be determined in mL. IM of gas = 24 dm3 or 24,000 ml. Therefore ImM of gas = 24 ml.

[0493] To calculate how many mM ethylene produced, divide amount by 24: mM ET= ml / 24

[0494] To calculate RATE: mM per hour per CFU, calculate mM as described above, and need to know how much of the headspace you sampled (if using calibration calculation e.g., 1 mL of headspace sampled has x mM gas but there is 6 mL headspace total so total ethylene produced = 6x mM). If calculating using peak area % only the above step is not necessary, just need to know how much acetylene you added. Need to know the number of hours of incubation withIl lAcetylene. Need to do TVCs to calculate CFU / ml then multiple your CFU value by the number of ml cultured e.g., 4mL (gncg) or 30 mL (gpos).

[0496] Ensure all equipment and materials are sterilized.

Cultures are inoculated to OD600 -0.05.13. Pass vials through Anaerobic chamber and seal under anaerobic conditions with and without Nitrogen - include an empty vial (with foil ‘cap’) to add an anaerobic indicator for QC purposes.14.8. To adjust oxygen levels, after sealing the vial, take a thin needle syringe and remove the portion of anaerobic air from the via which will be replaced with 100% pure medical grade oxygen.9. The assay has been ran at various oxygen conditions from 0% oxygen to 22% oxygen and can be increased to much higher oxygen conditions due to manual addition of oxygen. For example, to achieve 5% oxygen, remove 2.2mL anaerobic gas by hand and add 2mL of 100% pure oxygen back at this condition.10. Place vials in 30 C incubator for 5 hours.11. After 5 hours, working in the fume hood, remove 10% (4mL) from the headspace of each vial and replace with the same volume of acetylene gas.

[0500] Results are given in Tables 8a - 8d.Table 8a: ARA ResultsTable 8b: ARA Results for Edited StrainsTable 8c: ARA Results for Upstream EditsResults are given as comparative to the wild-type parent strain with no edits (+ is higher, - is lower, = is equivalent).Table 8d: ARA Results for noc KnockoutsResults are given as comparative to the wild-type parent strain with no edits (+ is higher, - is lower, = is equivalent).

[0501] Removal of the upstream xTxTC motif resulted in greater nitrogen fixation activity.

[0502] Deletion of nucleotides between the motif and nifB resulted in repression of nitrogen fixation activity.

[0503] Deleting a portion of the upstream region increased activity significantly when stacked with GlnR C25 truncation; however, deletion of 95 bp from the upstream region of CM8619 did not have the same effect as that seen in PM77155 even though both are strains of P. polymyxa in high ammonia condition. However, this edit was produced via blind editing from PM77155 template which may have unknown effects when combined with these mutations.

[0504] These data indicate that the identified “upstream” region may include a repressor of nitrogen fixation in the presence of nitrogen, because when it is deleted, there is more conversion activity. Alternatively, another regulatory region, or cellular genome alteration site, may be present. Thus, mutation in this region may be a method of modulating the nitrogen fixation capability of a bacterium.Root Colonization

[0505] Bacterial strains are prepared with the GFP gene integrated into its genome, using techniques known in the art. Seeds are treated with the strain(s), and using sterile technique, inoculated seeds are dropped into phytagel tubes. Tubes are placed in appropriate grow rooms and cover for 5 days to allow germination. The root tissue is separated from the seed and shoot, using EtOH and flame sterilized tweezers and scalpels. The root tissue is cut to all be in the same focal plane and pressed at the same level on 0.8% water-agar in a square plate to image. The same is performed for shoot tissue. The plant tissue is imaged for bacterial colonization using fluorescence microscopy.Biofilm Assay Protocol

[0506] This protocol is based on literature: “Effects of an EPS Biosynthesis Gene Cluster of Paenibacillus polymyxa WLY78 on Biofilm Formation and Nitrogen Fixation under AerobicConditions” (Chen 2021). Materials: Sterile 3 mL glass tubes, ‘Biofilm Broth (BFB)’ media, 0.1% Crystal Violet (aqueous) Solution, 40% Acetic acid. 7 days gave best overall biofilm results; some isolates can give better results over 5 days and start to break down after this timepoint. Prepare using sterile technique.

[0507] The recipe for BFB includes: 5g / L KH2PO4, 5g / L K2HPO4, 0.86 g / L Mono sodium glutamate, 0.1 g / L yeast extract, Ig / L NH4C1 pH 7. Filter sterilizing after autoclaved: 36g / L glucose, 0.03g / L MgSO4.7H2O, 0.02g / L CaC12.2H2O, 1 ml / L Trace element solution.

[0508] The method steps are:1. Streak isolates from -80 C.2. Make spread plates of each isolate.3. Autoclave 3 mL glass tubes in tube rack (x3 / isolate), use foil as a cover4. Harvest spread plates and OD600 balance to ~0.35. Fill each tube with 1 mL BFB.6. Inoculate with 10 uL / tube of spread plate harvest.7. Place foil cover back over tubes and incubate at 30 C, stationary for 7 days.8. After 7 days, start by removing the culture from tubes using long (1250 uL) pipette tips - collect culture in 2 mL snap cap tubes.9. Add water to the culture to reach final volume of 1 mL - Take OD600 reading.10. Wash glass tubes using RO water; fill approx, half-way, hold tube, sealing the top and shake to dislodge excess cellular material. Rinse several times.11. Remove excess water using long pipette tips.12. Add 1 mL / tube of 0.1% Crystal Violet solution and incubate for 10 minutes at room temperature.13. Remove Crystal Violet solution by pipette into a waste container (e.g., 50 mL falcon tube) and dispose in the incineration waste bin.14. Rinse glass tubes until water runs clear.15. Dry glass tubes (usually overnight).16. Add 1 mL 40% acetic acid solution to dissolve stained biofilm ring.17. Take OD570 reading.18. Normalize OD570 by OD600 (if appropriate).Example 9: In planta testing

[0509] The edited microbes described above were tested in at least one species of plant, in replicate.

[0510] Plants were associated with the wild-type and / or edited microbes described above, and tested in the greenhouse as well as in larger-scale field trials. Association may be accomplished by any one or more of the following, without limitation: seed treatment, foliar treatment, infurrow application, drench, side-dress.

[0511] Plants were treated with the microbes described herein and grown in the greenhouse (wheat, com) and / or in field trials (wheat, tomato, sugarbeet, soybean, silage, rice, potato, lettuce, com, cotton, and canola), according to standard methods. Data collected included biomass, leaf area, plant height, root area, shoot Nitrogen, greenness, NDVI (capturing how much more near infrared light is reflected compared to visible red; a measure of the state of plant health based on how the plant reflects light at certain frequencies), NPCI (normalized pigment chlorophyll ratio index), PSRI (plant senescence reflectance index), and CCI (chlorophyll content index), and compared to an untreated control.

[0512] Results are shown in Tables 9a - 9c.Table 9a: Greenhouse Results: Edits of Paenibacllus polymyxa Applied to WheatIOC = Improvement Over ControlTable 9b: Greenhouse Results: Edits of Paenibacllus polymyxa Applied to CornIOC - Improvement Over Control

[0513] Data for crops with positive effect in field trials are shown in Table 9c, for edited strain PE77155-G239 (GlnR C25 truncation + upstream deletion (dclta95)).Table 9c: Field Trial Results: Edits of Paenibacillus polymyxa Applied to Various Crops IOC = Improvement Over Control; Bu - bushels; Ac = acre; Bu Ac = bushels per acre;

[0514] For the sugarbeet, soybean, silage, potato, and lettuce trials, the treatment effects could not be determined as those field trial plots did not respond to nitrogen at that location for that year.

[0515] These results confirm that deletion of the described motif upstream of the nif cluster in Paenibacillus results in greater nitrogen fixation capability of the microbe, and thus improved yields across multiple different crops.
