Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 63 / 386,145, filed December 5, 2022, which is incorporated by reference herein in its entirety. Reference to an electronically submitted sequence listing

[0002] An official copy of the Sequence Listing has been submitted electronically as a Sequence Listing in WIPO ST26 compliant XML format with filename 22043_SeqListing.xml, created on November 30, 2023, and having a size of 625,708 bytes, and is being filed concurrently herewith. The Sequence Listing contained in this document is a part of the present specification and is incorporated herein by reference in its entirety.

[0003] The present disclosure relates to isolated, biologically pure microorganisms, particularly for agricultural applications. The disclosed microorganisms can be utilized in their isolated, biologically pure state or can be formulated into agriculturally acceptable compositions. Methods of using the isolated microorganisms or agriculturally acceptable compositions in agricultural applications are also disclosed. [Background technology]

[0004] According to the United Nations World Food Programme, there are nearly 900 million malnourished people in the world. The prevalence of malnutrition is particularly pronounced in the world's developing countries, where one in six children is underweight. The lack of available food can be attributed to many socioeconomic factors. However, whatever the ultimate cause, the fact remains that there is insufficient food to feed the growing world population, which is expected to reach 9 billion by 2050. The United Nations estimates that agricultural yields must increase by 70 to 100 percent to feed the projected world population in 2050.

[0005] These staggering global population and malnutrition figures highlight the importance of agricultural efficiency and productivity to sustain a growing world population. The technological advances achieved by modern row-crop agriculture are impressive, resulting in crop yields never before seen. However, despite advances made through technological innovations such as genetically modified crops and new novel insecticidal and herbicidal compounds, there remains a need for improved crop yields to meet the demands of an exponentially growing world population.

[0006] Scientists estimate that global crop production could increase by 45-70% if the world's agricultural "yield gap" (the difference between the most commonly observed yields and results elsewhere) could be closed. In other words, if all farmers, regardless of location, could achieve the highest yields expected in their region, a large portion of the world's food production shortfall could be addressed. However, the problem of how to achieve high yields in different parts of the world is difficult.

[0007] In many cases, yield disparities can be explained by insufficient water, substandard agricultural practices, inadequate fertilizer, or the failure to use herbicides or pesticides. However, significantly increasing global use of water, fertilizer, herbicides, and pesticides would not only be economically unfeasible for much of the world, but would also have adverse environmental effects.

[0008] Therefore, it is simply not feasible to meet agricultural production expectations by simply scaling up the current high-input agricultural systems used in most developed countries.

[0009] Thus, there is an urgent need in the art for improved methods for increasing crop yields and imparting beneficial traits to desired plant species.

[0010] The technology described herein is for the use of environmental nitrogen-fixing bacteria, particularly the genus Paenibacillus, to improve plants by increasing the amount of nitrogen fixed, enhancing the amount of nitrogen available to plants, and increasing final yield.Spore-forming bacteria such as Paenibacillus are known to be difficult to work with compared to more docile gram-negative bacteria such as Klebsiella, so the successful isolation, stable composition containing the bacteria that provides improved benefits to plants, and successful association with the plants are surprising and unexpected. Summary of the Invention

[0011] The disclosed microorganisms include isolated and biologically pure microorganisms, particularly for agricultural applications. The disclosed microorganisms can be utilized in their isolated and biologically pure state or can be formulated into agriculturally acceptable compositions. Additionally, agriculturally beneficial microbial consortia comprising at least two members of the disclosed microorganisms are provided, as well as methods for utilizing the consortia in agricultural applications.

[0012] Presented herein are strains of the spore-forming bacterium Paenibacillus, spanning multiple different species across both subgroups I and II of the genus, that contain a cluster of genes known to confer nitrogen fixation ability.

[0013] In one aspect, the novel strains of Paenibacillus described herein improve plant yield by enabling an increase and / or improvement in plant nitrogen availability, fixation, uptake, acquisition, tolerance, distribution, regulation, treatment, and / or any number of the foregoing and / or any combination of the foregoing.

[0014] In some embodiments, the plant is a non-legume crop plant.

[0015] In some embodiments, the plant is a dicotyledonous plant. In some embodiments, the plant is a vegetable, a medicinal herb, an ornamental plant, or a fruit plant. In some embodiments, the plant is selected from the group consisting of soybean, cotton, canola, rapeseed, kale, spinach, lettuce, carrot, potato, beet, radish, tomato, broccoli, cauliflower, pumpkin, mustard, berries, peppers, green leafy vegetables, climbing beans, cantaloupe, cucumber, basil, grapes, and okra.

[0016] In some embodiments, the plant is a monocotyledon. In some embodiments, the plant is a C3 monocotyledon. In some embodiments, the plant is a C4 monocotyledon. In some embodiments, the plant is selected from the group consisting of corn, 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, chive, forage grass, turf grass, buckwheat, quinoa, chia, and millet.

[0017] The solutions provided by the present disclosure to increasing crop yields and productivity are not detrimental to global resources because they do not rely on increased water consumption or increased synthetic chemical inputs to production systems. Rather, the present disclosure utilizes microorganisms to impart beneficial traits, including increased yield, to desirable plants.

[0018] Thus, the present disclosure provides an environmentally sustainable solution that enables farmers to increase yields of important crops and does not rely on increased use of synthetic herbicides and pesticides.

[0019] In embodiments, the present disclosure provides an efficient and broadly applicable agricultural platform that utilizes microorganisms and microbial consortia (multiple microorganisms, in some aspects multiple microorganisms that improve the health or desirable phenotype of the plant, such as an agronomic trait, with which it is associated) that promote one or more desirable plant characteristics.

[0020] The microorganisms disclosed herein improve plant yield, such as crop plants, through both direct and indirect mechanisms. In some embodiments, the microorganisms are symbiotic with the plant. In some embodiments, the microorganisms produce compounds (e.g., metabolites, toxins, proteins, lipopeptides, or other compositions) that confer a benefit to the plant or that the plant can use for improved characteristics. In some embodiments, the microorganisms improve the solubility of one or more compositions, such as nutrients, thereby benefiting the plant. In some embodiments, the microorganisms confer resistance to exogenous substances, such as herbicides or insecticides, on the plant. In some embodiments, the microorganisms produce compositions that are harmful to plant pests, such as insects. In some embodiments, the microorganisms fix nitrogen, thereby improving the nutritional status of the plant. Other embodiments beyond the exemplary, non-limiting embodiments listed above are also contemplated.

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

[0022] In some embodiments, the single microorganism, whether a taxonomically identifiable species or a taxonomically identifiable strain, is mixed with one or more other microorganisms of different species or strains. In certain embodiments, the combination of two or more microorganisms forms a consortium. The terms consortium and consortium are used interchangeably.

[0023] In certain aspects, the present disclosure provides for the development of highly functional microbial consortia that are useful for promoting the development and expression of desirable phenotypic or genotypic plant traits. In some embodiments, the consortia of the present disclosure possess functional properties not found in nature when individual microorganisms live alone. That is, in various embodiments, mixing specific microbial species into a consortium results in a mixture of microorganisms that possess functional properties not possessed by any single member of the consortium when viewed individually.

[0024] In some embodiments, the functional property possessed by the microbial consortium is the ability to confer one or more beneficial properties to a plant species, such as increased growth, increased yield, increased nutrient utilization (e.g., nitrogen, phosphate, etc.), improved nitrogen use efficiency, increased stress tolerance, increased drought tolerance, increased photosynthetic rate, enhanced water use efficiency, increased pathogen resistance, modifications to plant architecture that do not necessarily affect plant yield, but rather address plant functionality, etc. Additionally, beneficial properties of pest resistance and / or tolerance, including adverse effects on nematodes, insects, or other pests, are also contemplated.

[0025] In some embodiments, these individual microorganisms do not have the ability to confer these beneficial properties to plants when they exist in nature. Rather, in some embodiments, humans combine these microorganisms into consortia to develop functional compositions that possess attributes and functional properties not found in nature.

[0026] However, in other embodiments, the present disclosure provides isolated and biologically pure individual microorganisms that can impart beneficial traits to desired plant species and do not require mixing into a consortium.

[0027] Thus, the present disclosure provides an environmentally sustainable solution that enables farmers to increase yields of important crops without relying on increased use of synthetic fertilizers, herbicides, and / or pesticides.

[0028] The present disclosure further relates to agricultural compositions comprising one or more strains of the isolated microorganisms disclosed herein and an agriculturally acceptable carrier. In some embodiments, the agricultural composition comprises one or more additional agriculturally beneficial agents (e.g., fertilizers, biofertilizers, bionematicides, biostimulants, synthetic insecticides, and / or synthetic herbicides).

[0029] Also disclosed herein are methods for imparting one or more beneficial traits to a plant, the methods comprising applying an agriculturally effective amount of one or more of the microorganisms or agricultural compositions disclosed herein.

[0030] In some embodiments, the Paenibacillus strain is listed in Table 1. In some embodiments, the Paenibacillus strain comprises a polynucleotide sequence sharing at least 90% identity with any one or more of SEQ ID NOs: 1-293. In some embodiments, the Paenibacillus strain is a species selected from the group consisting of albidus, amylolyticus, anaericanus, azotifigens, borealis, chondroitinus, donghaensis, durus, graminis, helianthi, jilunlii, macerans, odorifer, panacisoli, peoriae, phoenicis, phytohabitans, polymyxa, rhizoplanae, silagei, sonchi, taohuashanense, thermophilus, tritici, typhae, wynnii, xylanexedens, and yonginensis. In some embodiments, the Paenibacillus strain is of subgroup I. In some embodiments, the Paenibacillus strain is of subgroup II.

[0031] Any strain disclosed herein can be further combined with one or more additional microorganisms to form a microbial consortium. A microbial consortium can be any combination of one or more individual microorganisms. In certain embodiments, the microbial consortium comprises two types of microorganisms, or three types of microorganisms, or four types of microorganisms, or five types of microorganisms, or six types of microorganisms, or seven types of microorganisms, or eight types of microorganisms, or nine types of microorganisms, or ten types of microorganisms, or more than ten types of microorganisms.

[0032] Another objective of the present disclosure is to design a microbial consortium that can perform multidimensional activities in the same way. In certain embodiments, the microorganisms that make up the consortium act synergistically. In certain embodiments, the effect that the microbial consortium has on a particular plant trait is greater than the effect observed when any one specific microbial member of the consortium is used alone. That is, in some embodiments, the consortium exhibits an effect on a desired plant trait that is greater than the sum of the effects seen when any one specific member of the consortium is used alone.

[0033] In some embodiments, the consortium establishes other plant-microbe interactions, for example, by serving as primary colonizers or founder populations that set the trajectory for future microbiome development.

[0034] In embodiments, the present 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 improved grain, fruit, and flower yields, improved plant part growth, improved ability to utilize nutrients (e.g., nitrogen, phosphate, and the like), improved disease resistance, biopesticidal effects including improved resistance to fungi, insects, and nematodes, increased ability to survive in extreme climates, and other desirable plant phenotypic characteristics. Importantly, such plant benefits and / or adverse effects against targeted pests and / or pathogens are obtained without any harmful side effects to the environment.

[0036] In some aspects, individual microorganisms or consortia comprising microorganisms of the present disclosure can be combined into agriculturally acceptable compositions.

[0037] In some embodiments, agricultural compositions of the present disclosure include, but are not limited to, wetting agents, compatibilizers, defoamers, detergents, sequestering agents, drift reducing agents, neutralizing agents, buffers, corrosion inhibitors, dyes, odorants, spreading agents, penetration aids, tackifiers, binders, dispersants, thickeners, stabilizers, emulsifiers, freezing point depressants, antimicrobials, fertilizers, pesticides, nematicides, insecticides, herbicides, inert carriers, polymers, and the like.

[0038] In one embodiment of the present disclosure, the microorganism (including an isolated single species, or strain, consortium, or composition thereof, such as metabolites) is provided to seeds in the form of a seed coating or other application. In embodiments, the seed coating may be applied to bare, untreated seeds. In other embodiments, the seed coating may be applied to previously treated seeds. Thus, in some embodiments, the present disclosure teaches a method of treating seeds comprising applying an isolated bacterial strain or microbial consortium to seeds. In certain embodiments, the isolated bacterial strain or microbial consortium is applied as an agricultural composition comprising an agriculturally acceptable carrier. In some embodiments, the agricultural composition may be formulated as a soil drench, foliar spray, dip treatment, in-furrow treatment, soil amendment, granule, broad-spectrum treatment, post-harvest disease control treatment, or seed treatment. In some embodiments, the agricultural composition may be applied alone or in a rotational application program with other agricultural products. In some embodiments, the agricultural composition may be compatible with tank-mixing. In some embodiments, the agricultural composition may be compatible with tank-mixing with other agricultural products. In some embodiments, the agricultural compositions may be compatible with equipment used in ground, aerial, and irrigation applications.

[0039] In some embodiments, the applied microorganisms may be endophytic, resulting in their presence on the growing treated plants and their progeny, while in other embodiments, the microorganisms may be applied simultaneously as a co-treatment with the seed treatment.

[0040] In one embodiment of the present disclosure, the microorganisms are provided in the form of granules, plugs, or soil drench applied to the plant growth medium. In other embodiments, the microorganisms are provided in the form of a foliar treatment, such as a foliar spray composition or a foliar liquid composition.

[0042] In other embodiments of the present disclosure, the microorganisms (including isolated single species or strains, or consortia) and / or compositions thereof (e.g., metabolites) are provided in the form of post-harvest disease control agents.

[0043] In embodiments, the agricultural compositions of the present disclosure may be formulated as, inter alia, (1) solutions, (2) wettable powders, (3) dusts, (4) soluble powders, (5) emulsifiable concentrates or suspensions, (6) seed dressings, (7) tablets, (8) water-dispersible granules, (9) water-soluble granules (slow-release or fast-release), (10) microencapsulated granules or suspensions, (11) irrigation components, and (12) components of fertilizers, pesticides, and other compatibility improvers. In certain aspects, the compositions may be diluted in an aqueous medium before conventional spray applications. The compositions of the present disclosure may be applied to soil, plants, seeds, the rhizosphere, rhizosheath, or other areas where applying a microbial composition is beneficial.

[0044] Yet another object of the present disclosure relates to agricultural compositions formulated to provide a bacterial population or consortium with a high colony forming unit (CFU). In some aspects, these agricultural compositions have an adjuvant that provides a suitable shelf life. In embodiments, the CFU concentration of the agricultural compositions of the present teachings is higher than the concentration of the microorganisms present in nature, i.e., outside of the methods of the present disclosure. In another embodiment, the agricultural composition includes microbial cells at a concentration of 10^2 to 10^12 CFU per gram of carrier or 10^5 to 10^9 CFU per gram of carrier. In one aspect, the microbial cells are applied directly to seeds as a seed coating at a concentration of 10^5 to 10^9 CFU. In another aspect, the microbial cells are applied over another seed coating as a seed overcoating at a concentration of 10^5 to 10^9 CFU. In another aspect, the microbial cells are applied as a co-treatment with another seed treatment at a rate of 10^5 to 10^9 CFU.

[0045] In an aspect, the present disclosure is directed to agricultural microbial formulations that promote plant growth. In an aspect, the present disclosure provides isolated microorganisms of the present teachings and consortia comprising the same, formulated as agricultural bioinoculants. The bioinoculants of the teachings can be applied to plants, seeds, or soil, or can be combined with fertilizers, pesticides, and other compatibility improvers. Suitable examples of bioinoculant formulations comprising isolated microorganisms can be found in U.S. Patent No. 7,097,830, incorporated herein by reference.

[0046] The disclosed microbial formulations can reduce the need for nitrogen-containing fertilizers, solubilize minerals, provide bio-pesticide protection for plants, protect plants from pathogens (e.g., fungi, insects, and nematodes), and make valuable nutrients such as nitrogen and / or phosphate available to plants, thus reducing and eliminating the need to use chemical pesticides and fertilizers.

[0051] In some embodiments, the isolated, biologically pure microorganisms of the present disclosure and / or the consortium of the present disclosure are obtained from an accelerated microbial selection process ("AMS" process). The AMS process utilized in some embodiments of the present disclosure is described, for example, in (1) International Patent Application No. PCT / NZ2012 / 000041, published on September 20, 2012 as WO 2012125050A1, and (2) International Patent Application No. PCT / NZ2013 / 000171, published on March 27, 2014 as WO 2014046553A1, each of which is incorporated herein by reference in its entirety for all purposes.

[0083] Although the following terms are believed to be well understood by those of ordinary skill in the art, the following are set forth to facilitate explanation of the subject matter of the present disclosure.

[0084] The term "a" or "an" refers to one or more of that entity, i.e., can refer to a plurality of referents. Thus, 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 a plurality of elements are present, unless the context clearly requires that there be only one of that element.

[0085] The term "substantially" means to a great extent and is intended to refer to conditions that are substantially optimal for the purpose to which it pertains. For example, "substantially purified" means that a desired component of a composition has been removed from most of the other components, making the desired component the primary component of the composition. In another example, "substantially isolated" means, for example, that a microorganism has been removed from its naturally occurring environment and from most or all of the other components that may be present with it.

[0086] As used herein, the terms "microorganism" or "microbe" should be interpreted broadly. These terms are used interchangeably and include, but are not limited to, the two prokaryotic domains, Bacteria and Archaea, and Eukaryotes and Protists. In some embodiments, the present disclosure refers to the "microorganisms" of Table 1 or various other tables or paragraphs present in this disclosure. This characterization can refer not only to the identified taxonomic bacterial genera of a table, but also to the identified taxonomic bacterial species, and to various novel and newly identified bacterial strains of the table.

[0087] As used herein, the terms "microbe" or "microorganism" refer to any microbial species or taxon, 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 an individual cell (e.g., a unicellular microorganism) or multiple cells (e.g., a multicellular microorganism). Thus, a "population of microorganisms" can refer to multiple cells of a single microorganism that share a common genetic origin.

[0088] As used herein, the term "bacterium" generally refers to any prokaryotic organism and may refer to organisms of either the kingdom Eubacteria (bacteria), the kingdom Archaea (archaea), or both. In some cases, bacterial genera or other taxonomic classifications may be in taxonomic flux, reassigned for 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 reassignments are within the scope of any claimed taxonomy. For example, certain species of the genus Erwinia are described in the literature as belonging to the genus Pantoea (Zhang, Y., Qiu, S. Examining phylogenetic relationships of Erwinia and Pantoea species using whole genome sequence data. Antonie van Leeuwenhoek 108, 1037-1046 (2015)). The genus Paenibacillus includes the species and strains described herein, although specific classification may change based on microbiological criteria and / or future developments in sequencing methodology.

[0089] The term "16S" refers to the DNA sequence of a bacterial 16S ribosomal RNA (rRNA) sequence. 16S rRNA gene sequencing is an established method for studying bacterial phylogeny and taxonomy.

[0166] As used herein, the term "fungus (or fungi)" generally refers to any organism from the kingdom Fungi. Historical taxonomic classification of fungi is by morphological presentation. Beginning in the mid-1800s, it was recognized that some fungi have pleomorphic life cycles, and different nomenclature designations are used for different forms of the same fungus. In 1981, the Sydney Congress of the International Mycological Association established rules for naming 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 genome sequencing, it became clear that taxonomic classification based on molecular phylogeny was incompatible with morphology-based nomenclature (Shenoy, B.D., Jewon, 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), which described the consequence 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)).

[0090] The term "internal transcribed spacer" (ITS) refers to the spacer DNA (non-coding DNA) located between the small subunit ribosomal RNA (rRNA) gene and the large subunit (LSU) rRNA gene in a chromosome, or the corresponding transcribed region in a polycistronic rRNA precursor transcript. ITS gene sequencing is an established method for studying fungal phylogeny and taxonomy. In some cases, the "large subunit" ("LSU") sequence is used to identify fungi. LSU gene sequencing is an established method for studying fungal phylogeny and taxonomy. Some fungal microorganisms of the present invention can be described by their ITS sequence, and some by their LSU sequence. It is understood that both are equally descriptive and accurate for determining taxonomy.

[0091] The term "microbial consortia" or "microbial consortium" refers to a subset of a microbial community consisting of individual microbial species or strains of species, which may be described as performing a common function or may be described as relating to, causing, or correlating with a recognizable parameter or plant phenotypic trait. A community may include one or more species or strains of species of microorganisms. In some cases, microorganisms coexist symbiotically within a community.

[0092] The term "microbial community" refers to a group of microorganisms comprising two or more species or strains. Unlike a microbial consortium, a microbial community does not necessarily perform a common function or relate to, cause, or correlate with a discernible parameter or plant phenotypic trait.

[0093] The term "rapid microbial sorting" or "AMS" is used interchangeably with the term "directional microbial sorting" or "DMS" and refers, in some embodiments of the present disclosure, to an iterative sorting method utilized to obtain the claimed microbial species or consortia of such species.

[0094] As used herein, "isolate," "isolated," "isolated microorganism," and similar terms are intended to mean that one or more microorganisms are separated from at least one of the substances with which they are associated in a particular environment (e.g., soil, water, plant tissue).

[0095] Thus, an "isolated microorganism" is not present in its naturally occurring environment. Rather, through various techniques described herein, the microorganism has been removed from its natural environment and placed in a non-naturally occurring state. Thus, the isolated strain may exist, for example, as a biologically pure culture or as spores (or other form of the strain) associated with an agricultural carrier.

[0096] In certain embodiments of the present disclosure, the isolated microorganism exists as an isolated, biologically pure culture. An isolated, biologically pure culture of a particular microorganism is understood by those skilled in the art to indicate that other organisms are substantially absent from the culture (for scientific reasons), and that only the individual microorganism in question is present in the culture. The culture may contain various concentrations of the microorganism. The present disclosure notes that an isolated, biologically pure microorganism is often "necessarily distinct from less pure or impure material." See, e.g., re. Bergstrom, 427 F.2d 1394, (CCPA 1970) (discussing purified prostaglandins); and re. Bergy, 596 F.2d 952 (CCPA 1979) (discussing purified microorganisms); and Parke-Davis & Co. v. HK Mulford & Co., 189 F.95 (SDNY 1911) (Learned Hand discussing purified adrenaline), partially affirmed and partially overturned, 196 F.496 (2d Cir. 1912), each of which is incorporated herein by reference. Furthermore, in some aspects, the present disclosure prescribes certain quantitative measures of concentration or purity limits that must be found in isolated, biologically pure microbial cultures. In certain embodiments, the presence of these purity values ​​is an additional attribute that distinguishes the microorganisms of the present disclosure from those present in nature. See, for example, Merck & Co. v. Olin Mathieson Chemical Corp., 253 F.2d 156 (4th Cir. 1958), which is incorporated herein by reference (discussing purity limits for microbially produced vitamin B12).

[0097] As used herein, "individual isolate" should be understood to mean a composition or culture that predominantly contains microorganisms of a single genus, species, or strain after separation from one or more other microorganisms. The phrase should not be understood to refer to the extent to which the microorganism has been isolated or purified. However, an "individual isolate" can contain microorganisms of substantially only one genus, species, or strain.

[0098] As used herein, the term "growth medium" refers to any medium suitable for supporting plant growth. By way of example, the medium may be a natural or artificial medium, including, but not limited to, soil, potting soil, bark, vermiculite, hydroponic solutions alone and applied to solid plant support systems, and tissue culture gels. It should be understood that these media may be used alone or in combination with one or more other media. These media may also be used with or without the addition of exogenous nutrients and physical support systems for the roots and leaves.

[0099] In one embodiment, the growth medium is a naturally occurring medium such as soil, sand, mud, clay, humus, topsoil, stone, or water. In another embodiment, the growth medium is artificial. Such artificial growth media may be constructed to mimic the conditions of naturally occurring media; 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, and water. In one embodiment, the growth medium is sterile. In another embodiment, the growth medium is not sterile.

[0100] The media may be amended or enriched with additional compounds or components, such as components that may aid in the interaction and / or selection of specific groups of microorganisms with plants and with each other. For example, antibiotics (such as penicillin) or sterilizing agents (e.g., quaternary ammonium salts and oxidizing agents) may be present, and / or physical conditions (salt, plant nutrients (e.g., organic and inorganic minerals, such as phosphorus, nitrogen-containing salts, ammonia, potassium, and micronutrients such as cobalt and magnesium), pH, and / or temperature) may be modified.

[0101] The term "plant" generally includes whole plants, plant organs, plant tissues, seeds, plant cells, seeds, and their progeny. Plant cells include, but are not limited to, cells derived from seeds, suspension cultures, embryos, meristematic regions, callus tissue, leaves, roots, shoots, gametophytes, sporophytes, pollen, and microspores. Progeny, variants, and mutants of regenerated plants are also included within the scope of the present invention, provided that these portions contain the introduced polynucleotide.

[0102] "Plant element" is intended to refer to either whole plants or plant components, which may include differentiated and / or undifferentiated tissues, such as, but not limited to, plant tissues, parts, and cell types. As used herein, the term "plant element" refers to plant cells, plant protoplasts, plant cell tissue cultures from which plants can be regenerated, plant callus, plant clumps, and intact plant cells in plants or parts of plants, such as embryos, pollen, ovules, seeds, leaves, flowers, branches, fruits, grains, ears, cobs, husks, stems, roots, root tips, anthers, and the like, as well as plants themselves. In one embodiment, the plant element is one of the following: whole plants, seedlings, meristems, ground tissues, vascular tissues, skin tissues, seeds, leaves, roots, shoots, stems, flowers, fruits, stolon, bulbs, tubers, corms, stems, shoots, buds, tumor tissue, and various forms of cells and cultures (e.g., single cells, protoplasts, embryos, callus tissue). The term "plant organ" refers to a plant tissue or group of tissues that constitutes a morphologically and functionally distinct part of a plant. As used herein, "plant part" is synonymous with "portion" of a plant, refers to any part of a plant, can include distinct tissues and / or organs, and can be used interchangeably with the term "tissue" throughout.

[0103] Similarly, "plant reproductive element" is generally intended to refer to any part of a plant that is capable of initiating another plant through either sexual or asexual reproduction of that plant, such as, but not limited to, a seed, seedling, root, shoot, cutting, scion, explant, stolon, bulb, tuber, corm, keiki, or sprout. A plant element can be in a plant, or in a plant organ, tissue culture, or cell culture.

[0104] "Progeny" includes any descendant of an organism produced through sexual or asexual reproduction.

[0105] "Grain" is intended to mean mature seed produced by commercial growers for purposes other than seed growth or reproduction.

[0106] The terms "monocotyledonous" or "monocotyledonous plant" refer to the subclass of angiosperms, also known as "monocotyledons," whose seeds typically contain only one germ leaf or cotyledon. The term includes reference to whole plants, plant elements, plant organs (e.g., leaves, stems, roots, etc.), seeds, plant cells, and their progeny.

[0107] The terms "dicotyledonous" or "dicot" refer to the subclass of angiosperms, also known as "dicots," whose seeds typically contain two germ leaves or cotyledons. The term includes reference to whole plants, plant elements, plant organs (e.g., leaves, stems, roots, etc.), seeds, plant cells, and their progeny.

[0108] As used herein, the term "cultivar" refers to a variety, strain, or variety of a plant created by horticultural or agronomic techniques and not normally found in natural populations.

[0109] As used herein, "improved" should be broadly understood to encompass an improvement in a characteristic of a plant compared to a control plant or compared to a known average amount associated with the characteristic in question. For example, "improved" plant biomass associated with application of the beneficial microorganisms or consortium of the present disclosure can be demonstrated by comparing the biomass of a plant treated with the microorganisms taught herein to the biomass of an untreated control plant. Alternatively, it is possible to compare the biomass of a plant treated with the microorganisms taught herein to the average biomass normally achieved by a given plant as shown in scientific or agricultural publications known to those of skill in the art. In the present disclosure, "improvement" does not necessarily require that the data be statistically significant (e.g., p<0.05). Rather, any quantifiable difference demonstrating that one value (e.g., the average treatment value) is different from another value (e.g., the average control value) can rise to the level of "improvement."

[0110] As used herein, "inhibiting and suppressing" and similar terms should not be construed as requiring complete inhibition or suppression, although this may be desirable in some embodiments.

[0111] As used herein, the term "genotype" refers to the genetic makeup of an individual cell, cell culture, tissue, organism (e.g., plant), or group of organisms.

[0112] The compositions and methods herein may provide improved "agronomic traits" or "agronomically important characteristics" or "traits of agronomic interest" in plants, which may include, but are not limited to, disease resistance, drought tolerance, heat tolerance, cold tolerance, salt tolerance, metal tolerance, herbicide tolerance, improved water use efficiency, improved nitrogen utilization, improved nitrogen fixation, pest and disease resistance, herbivore resistance, pathogen resistance, improved yield, improved health, improved vigor, improved growth, improved photosynthetic capacity, nutritional enhancement, altered protein content, altered oil content, increased biomass, increased shoot length, increased root length, improved root architecture, modulation of metabolites, modulation of the proteome, increased seed weight, altered seed carbohydrate composition, altered seed oil composition, altered seed protein composition, altered seed nutrient composition, compared to an isogenic plant that does not include the modification resulting from the methods or compositions herein.

[0113] "Agronomic trait potential" is intended to mean the ability of a plant element, at a certain point in its life cycle, to exhibit a phenotype, preferably an improved agronomic trait, or to transmit said phenotype to another plant element with which it is associated in the same plant.

[0114] As used herein, the terms "molecular marker," "marker," or "genetic marker" refer to indicators used in methods for visualizing differences in nucleic acid sequence characteristics. Examples of such indicators are restriction fragment length polymorphism (RFLP) markers, amplified fragment length polymorphism (AFLP) markers, single nucleotide polymorphisms (SNPs), insertion mutations, microsatellite markers (SSRs), sequence-specific amplified regions (SCARs), cleaved amplified polymorphic sequences (CAPS) markers, or isozyme markers, or combinations of markers described herein, which define specific genetic and chromosomal locations. Mapping molecular markers near an allele is a technique that can be performed by those skilled in the art of molecular biology.

[0115] As used herein, the term "trait" refers to a characteristic or phenotype. For example, in the context of some embodiments of the present disclosure, crop yield relates to the amount of marketable biomass (e.g., fruit, fiber, grain) produced by a plant. Desirable traits may also include other characteristics of a plant, including, but not limited to, water use efficiency, nutrient use efficiency, yield, feasibility of mechanical harvesting, fruit maturity, storage life, pest / disease resistance, early plant maturity, stress tolerance, etc. Traits may be dominantly or recessively inherited, or may be partially or incompletely dominantly inherited. Traits may be monogenic (i.e., determined by a single locus) or polygenic (i.e., determined by multiple loci), or may result from the interaction of one or more genes with the environment.

[0116] As used herein, the term "phenotype" refers to the observable characteristics of an individual cell, cell culture, organism (e.g., plant), or group of organisms that result from the interaction between the genetic constitution (i.e., genotype) of the individual and the environment.

[0117] 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 contain at least one nucleotide difference compared to any other naturally occurring nucleotide sequence.

[0118] As used herein, the term "nucleic acid" refers to a polymeric form of nucleotides of any length, either ribonucleotides or deoxyribonucleotides, or their analogs. The 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. The term also includes modified nucleic acids, such as methylated and / or capped nucleic acids, nucleic acids containing modified bases, nucleic acids containing backbone modifications, etc. The terms "nucleic acid" and "nucleotide sequence" are used interchangeably.

[0119] As used herein, the term "gene" refers to any segment of DNA associated with a biological function. Thus, a gene includes, but is not limited to, a coding sequence and / or regulatory sequences required for expression of the coding sequence. Genes can also include non-expressed DNA segments that form, for example, recognition sequences for other proteins. Genes can be obtained from a variety of sources, including cloning from a source of interest or synthesis from known or predicted sequence information, and can include sequences designed to have desired parameters.

[0120] As used herein, the terms "homologous," "homologue," "homolog," or "ortholog" are known in the art and refer 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. These terms refer to nucleic acid fragments whose ability to mediate gene expression or to produce a particular phenotype is unaffected by changes in one or more nucleotide bases. Therefore, as one of skill in the art will appreciate, it is understood that the present disclosure encompasses sequences other 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 "homologs" or "orthologs" are thought, believed, or known to be functionally related. Functional relationship can be expressed in any one of a number of ways, including, but not limited to, (a) degree of sequence identity and / or (b) identical or similar biological function. Preferably, both (a) and (b) are expressed. Homology can be determined using software programs readily available in the art, such as those discussed in Current Protocols in Molecular Biology (F.M.A. Usubel et al., eds., 1987), Supplement 30, section 7.718, Table 7.71. Some alignment programs are MacVector (Oxford Molecular Ltd, Oxford, UK), 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.

[0121] As used herein, the term "nucleotide change" refers to, for example, a nucleotide substitution, deletion, insertion, chemical modification, or any of the foregoing, as is well understood in the art.

[0122] As used herein, the term "protein modification" refers to, for example, amino acid substitutions, amino acid modifications, deletions, and / or insertions, as is well understood in the art.

[0123] As used herein, the term "at least a portion" or "fragment" of a nucleic acid or polypeptide refers to a minimum size characteristic of such a sequence, or any larger fragment of a full-length molecule, up to and including the full-length molecule. Fragments of polynucleotides of the present disclosure may encode biologically active portions of gene regulatory factors. Biologically active portions of gene regulatory factors can be prepared by isolating a portion of one of the polynucleotides of the present disclosure that contains a gene regulatory factor and assessing activity, as described herein. Similarly, portions of a polypeptide can be four amino acids, five amino acids, six amino acids, seven amino acids, etc., up to the full-length polypeptide. The length of the portion used will depend on the particular application. A portion of a nucleic acid useful as a hybridization probe can be as short as 12 nucleotides. In some embodiments, this is 20 nucleotides. A portion of a polypeptide useful as an epitope can be as short as four amino acids. A portion of a polypeptide that performs the function of a full-length polypeptide will generally be longer than four amino acids.

[0124] As used herein, the term "primer" refers to an oligonucleotide capable of annealing to an amplification target, serving as a starting point for DNA synthesis, when placed under conditions conducive to the synthesis of a primer extension product, i.e., in the presence of nucleotides and a polymerization agent, such as a DNA polymerase, and a suitable temperature and pH, allowing the DNA polymerase to attach and thereby serving as a starting point for DNA synthesis. (Amplification) primers are preferably single-stranded to maximize amplification efficiency. The primer is preferably an oligodeoxyribonucleotide. The primer must be sufficiently long to initiate the synthesis of an extension product in the presence of a polymerization agent. The exact length of the primers depends on many factors, including temperature and primer composition (A / T vs. G / C content). A bidirectional primer pair consists of one forward and one reverse primer, as commonly used in the art of DNA amplification, such as primers in PCR amplification.

[0125] The terms "stringency" or "stringent hybridization conditions" refer to hybridization conditions, such as temperature, salt concentration, pH, and formamide concentration, that affect hybrid stability. These conditions are empirically optimized to maximize specific binding of a primer or probe to its target nucleic acid sequence and minimize nonspecific binding. As used herein, the terms include reference to conditions under which a probe or primer hybridizes to its target sequence at a detectable level (e.g., at least 2-fold over background) relative to other sequences. Stringent conditions are sequence-dependent and will vary under various circumstances. Larger sequences hybridize specifically at higher temperatures. Stringent conditions are generally selected to be approximately 5°C lower than the melting temperature (Tm) of a 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. Stringent conditions typically involve a pH of 7.0-8.3, a salt concentration of less than about 1.0 M Na+ ions, typically about 0.01-1.0 M Na+ ions (or other salts), and a temperature of at least about 30°C for short probes or primers (e.g., 10-50 nucleotides) and at least about 60°C for long probes or primers (e.g., greater than 50 nucleotides). Stringent conditions can also be achieved by the addition of destabilizing agents such as formamide. Exemplary low-stringency or reduced-stringency conditions include hybridization with a buffer of 30% formamide, 1 M NaCl, and 1% SDS at 37°C, followed by a wash in 2×SSC at 40°C. Exemplary high-stringency conditions include hybridization in 50% formamide, 1 M NaCl, and 1% SDS at 37°C, followed by a wash in 0.1×SSC at 60°C. Hybridization procedures are well known in the art and are described, for example, in Ausubel et al., 1998 and Sambrook et al., 2001.In some embodiments, stringent conditions are hybridization in 0.25 M NaHPO buffer (pH 7.2) containing 1 mM NaEDTA, 0.5-20%, e.g., 0.5%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, or 20% sodium dodecyl sulfate at 45°C, followed by washing in 5x SSC containing 0.1% (weight / volume) sodium dodecyl sulfate at 55°C to 65°C.

[0126] In some embodiments, the cell or organism has at least one heterologous trait. As used herein, the term "heterologous trait" refers to a phenotype conferred on a cell or organism by an exogenous molecule or another organism (e.g., a microorganism), DNA segment, heterologous polynucleotide, or heterologous nucleic acid.

[0127] A variety of phenotypic changes are of interest to the present disclosure, including, but not limited to, modifying the fatty acid composition in plants, altering the amino acid content of plants, altering the pathogen defense mechanisms of plants, increasing plant yield for economically important traits (e.g., grain yield, forage yield, etc.), etc. These results can be achieved by expressing heterologous products or by increasing the expression of endogenous products in plants using the methods and compositions of the present disclosure.

[0128] A "synthetic combination" can include a mixture of a plant and a microorganism of the present disclosure. The mixture can be achieved, for example, by coating the surface of a seed of a plant, such as an agricultural plant, or host plant tissue (roots, stems, leaves, etc.) with a microorganism of the present disclosure. Furthermore, a "synthetic combination" can include a combination of different strains or species of microorganisms. A synthetic combination has at least one variable that distinguishes it from any combination that occurs in nature. That variable may be, in particular, a concentration of microorganisms on the seed or plant tissue that does not occur in nature, or a combination of microorganisms and plants that does not occur in nature, or a combination of microorganisms or strains that does not occur in nature. In each of these examples, the synthetic combination exhibits artificiality and possesses structural and / or functional properties that are not present when the individual components of the mixture are considered in isolation.

[0129] In some embodiments, a microorganism may be "endogenous" to a seed or plant. As used herein, a microorganism is considered "endogenous" to a plant or seed if it originates from the herbarium specimen from which it is procured; that is, if the microorganism is found naturally in association with the plant. In embodiments in which an endogenous microorganism is applied to a plant, the endogenous microorganism is applied in an amount that differs from the level found on the plant in nature. Thus, if a microorganism that is endogenous to a given plant is present on the plant at a level that does not occur naturally, the microorganism may still form a synthetic combination with the plant.

[0130] In some embodiments, a composition (such as a microorganism) can be "heterologous" (also referred to as "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 microorganism is considered "heterologous" to a plant or seed if it is not native to the plant specimen from which it is obtained; that is, if the microorganism is not naturally found in association with that plant. For example, a microorganism normally associated with the leaf tissue of one corn plant would be considered foreign to the leaf tissue of another corn plant that does not naturally harbor that microorganism. In another example, a microorganism normally associated with a corn plant would be considered foreign to a wheat plant that does not naturally harbor that microorganism.

[0131] A composition is "heterologously disposed" when it is mechanically or manually applied, artificially inoculated, associated, or disposed on or in a plant element, seedling, plant, plant growth medium, or treatment formulation in a manner not found in nature prior to application of the treatment, e.g., such that the treatment is present on or in a plant element, seedling, plant, plant growth medium, or treatment formulation in a manner not found in nature prior to application of the treatment, e.g., such that the combination is not found in nature in that plant variety, at that plant developmental stage, in that plant tissue, in that abundance, or in that growth environment (e.g., drought). In some embodiments, such a manner is contemplated to be selected from the group consisting of the presence of a microorganism; the presence of a microorganism in a different number of cells, concentration, or amount; the presence of a microorganism in different plant elements, tissues, cell types, or other physical locations within or on a plant; the presence of a microorganism at a different time period, e.g., developmental stage, time of day, or season of the plant or plant element; and combinations thereof. In some embodiments, "heterologously disposed" means that the microorganism is applied to a tissue or cell type of a plant element that is different from that in which the microorganism is found in nature. In some embodiments, "heterologously located" means that a microorganism is applied to a plant element, seedling, or developmental stage of a plant with which the microorganism is not naturally associated, but may be associated at other stages. For example, if a microorganism is normally found at the flowering stage of a plant but not at other stages, the microorganism applied at the seedling stage would be considered heterologously located. In some embodiments, a microorganism is heterologously located where the microorganism is normally found in the root tissue of a plant element but not in the leaf tissue, and the microorganism is applied to the leaf. In another non-limiting example, if a microorganism is naturally found in the mesophyll layer of leaf tissue but is applied to the epidermis layer, the microorganism would be considered heterologously located. In some embodiments, "heterologously located" means that a native plant element, seedling, or plant does not contain detectable levels of the microorganism in that same plant element, seedling, or plant. In some embodiments, "heterologously located" means that the microorganism being applied is in a concentration, number, or amount in the plant element, seedling, or plant that exceeds the concentration, number, or amount naturally found in the plant element, seedling, or plant.For example, a microorganism is heterologously disposed if it is present in a number, amount, or concentration that is at least 1.5-fold higher, 1.5-2-fold higher, 2-fold higher, 2-3-fold higher, 3-fold higher, 3-5-fold higher, 5-fold higher, 5-7-fold higher, 7-fold higher, 7-10-fold higher, 10-fold higher, or even greater than 10-fold higher than the concentration present prior to disposition of the microorganism. In another non-limiting example, a microorganism naturally found in the tissue of a tree of the Cupressaceae family would be considered heterologous to the tissue of a corn, wheat, cotton, or soybean plant. In another example, a microorganism naturally found in the leaf tissue of a corn, spring wheat, cotton, or soybean plant would be considered heterologous to the leaf tissue of another corn, spring wheat, cotton, or soybean plant that naturally lacks the microorganism or contains the microorganism in a different amount.

[0132] A microorganism can also be "heterologously distributed" on a given plant tissue. This means disposing the microorganism on plant tissue where it is not naturally found. For example, if a given microorganism naturally occurs only in the roots of a given plant, the microorganism can be exogenously applied to the above-ground tissue of the plant, thereby "heterologously disposing" the microorganism on the plant tissue. Thus, a microorganism is considered to be heterologously distributed when it does not naturally have any other microorganisms present, or when it does not naturally have any other microorganisms present in the numbers being applied.

[0133] The compositions and methods herein may provide a host plant with "modulated" "agronomic traits" or "agronomically important traits," including, but not 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, improved growth, improved health, 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, compared to an isogenic plant grown from seed without the use of the seed treatment formulation. , increased yield, increased yield under limited water conditions, grain mass, grain moisture content, metal tolerance, panicle number, kernel number per panicle, pod number, nutritional enhancement, pathogen resistance, pest and disease resistance, improved photosynthetic capacity, salt tolerance, greening, improved plant vigor, increased mature seed dry weight, increased mature seed fresh weight, increased number of mature seeds per plant, chlorophyll content, increased pod number per plant, increased pod length per plant, reduced number of wilted leaves per plant, reduced number of severely wilted leaves per plant, and increased number of unwilted leaves per plant, a detectable change in the level of a metabolite, a detectable change in the level of a transcript, and a detectable change in the proteome. By the term "modulated" it is intended to refer to a change in an agronomic trait that is modulated by the presence of a microorganism, exudate, broth, metabolite, etc. In an aspect, the modulation provides for the impartation of a beneficial trait. Microbe and microorganism

[0134] As used herein, the term "microorganism" should be interpreted broadly and includes, but is not limited to, prokaryotic bacteria and archaea, as well as eukaryotic bacteria and protists.

[0135] In certain embodiments, the microorganism is an endophyte or epiphyte, or a microorganism that resides in the plant rhizosphere or rhizocteth, i.e., the microorganism may be found present in soil material attached to the roots of the plant or in the area immediately adjacent to the roots of the plant.

[0136] In one embodiment, the microorganism is an endophyte. Endophytes can benefit the host plant by preventing pathogenic organisms from infecting the host plant. The widespread infection of plant tissues by endophytes creates a "barrier effect" in which the endophytes in that area outcompete pathogenic organisms and prevent pathogenic organisms from establishing themselves. Endophytes can also produce chemicals that inhibit the growth of competitors, including pathogenic organisms.

[0137] In certain embodiments, the microorganism is non-culturable, which should be understood to mean that the microorganism is not known to be culturable or that it is difficult to cultivate the microorganism using methods known to those skilled in the art.

[0138] The microorganisms of the present disclosure may be collected or obtained from any source, or may be contained within and / or associated with material collected from any source.

[0139] In one embodiment, a microorganism or combination of microorganisms may provide a possible or predicted benefit to a plant. For example, a microorganism may be predicted to improve nitrogen fixation, release phosphate from soil organic matter, release phosphate from inorganic forms of phosphate (e.g., phosphate rock), "fix carbon" in root microspheres, reside in the plant's rhizosphere, thereby helping the plant absorb nutrients from the surrounding soil and then more easily provide them to the plant, increase the number of nodules on the plant's roots, thereby increasing the number of symbiotic nitrogen-fixing bacteria (e.g., Rhizobium species) per plant and the amount of nitrogen fixed by the plant, trigger a plant defense response such as ISR (induced systemic resistance) or SAR (systemic acquired resistance) that helps plants resist the invasion and spread of pathogenic microorganisms, compete with microorganisms harmful to plant growth or health through antagonism or competitive use of resources such as nutrients or space, change the color of one or more parts of the plant, or change the plant's chemical profile, its odor, taste, or one or more other qualities.

[0140] The microorganisms of the present disclosure may be isolated in the form of substantially pure cultures or mixed cultures. They may be concentrated, diluted, or provided at the natural concentrations at which they are found in the source material. For example, microorganisms derived from saline sediments may be isolated for use in the present disclosure by suspending the sediment in fresh water and allowing the sediment to settle to the bottom. After a suitable period of settling, the water containing most of the microorganisms may be decanted and applied directly to plant growth medium, or it may be concentrated by filtering or centrifugation, diluted to an appropriate concentration to remove most of the salts, and then applied to plant growth medium. As a further example, microorganisms derived from mineralized or toxic sources may be similarly treated to minimize potential damage to plants and recovered for application to plant growth material.

[0141] In some embodiments, a mixed population of microorganisms is used in the methods of the present disclosure.

[0142] Nitrogen fixation in Paenibacillus. Gram staining is an imperfect method of taxonomically differentiating bacteria because clades generally accepted as either Gram-positive or Gram-negative may contain species or taxa that produce the opposite reaction in Gram strains. Some genera of Bacillata, primarily in the class Negativicutes, are known to be Gram-staining Gram-negative due to the presence of a porous pseudoexternal membrane. The family Paenibacillaceae is known to contain Gram diversity. The genera Ammoniphilus and Saccharibacillus of the Paenibacillaceae are Gram-variable, while the genera Longirhabdus and Thermobacillus are Gram-negative.

[0143] In nitrogen-fixing, spore-forming bacteria, the nif operon controls the nitrogen fixation pathway through GlnR. Binding of GlnR to site I activates Nif expression, whereas binding of GlnR to site II represses Nif expression.

[0144] Within the genus Paenibacillus, there are two distinct subgroups, subgroup I and subgroup II, each containing a different operon composition. Subgroup I Paenibacillus, such as Paenibacillus polymyxa, contains nifB, nifH, nifD, nifK, nifE, nifN, nifX, hesA, and nifV, in that order. Subgroup II Paenibacillus, such as Paenibacillus graminis, contains nifB, nifH, nifD, nifK, nifE, nifX, orf1, hesA, and nifV, in that order.

[0145] Most Paenibacillus bacteria utilize components of the canonical nif cluster to carry out various aspects of nitrogen fixation through protein complexes of NifD / NifK and NifE / NifN with the cofactors molybdenum and iron, as described above. Some bacteria are known to contain other nitrogen fixation cluster components, such as anf (which uses only iron) or vnf (which uses vanadium), forming protein complexes of six components instead of four. Some Paenibacillus species described herein utilize both the canonical nif cluster and the anf cluster.

[0146] nifH The nitrogenase enzyme complex consists of two conserved proteins: the MoFe protein, which consists of subunits encoded by the nifD and nifK genes, and the Fe protein, which is encoded by the nifH gene. The nitrogenase iron protein gene, nifH, is one of the oldest existing functional genes in the history of genetic evolution. The protein encoded by nifH is a dinitrogenase reductase that provides electrons to NifDK for nitrogen reduction.

[0147] The nucleotide sequences for the coding regions of the nifHDK genes are highly conserved among all nitrogen-fixing organisms, however, the copy number and arrangement of nifH, nifD, and nifK differ among various diazotrophic bacteria.

[0148] glnR In Paenibacillus bacteria, the nif operon controls the nitrogen fixation pathway via GlnR, and nif operon gene transcription is regulated by ammonium and oxygen. The protein encoded by glnR is a nitrogen-responsive helix-turn-helix transcription factor that regulates the expression of many targets, including nif genes.

[0149] Binding of GlnR to site I activates Nif expression, whereas binding of GlnR to site II represses Nif expression. Furthermore, GlnR has a high affinity for binding to site II.

[0150] cueR Structurally similar to GlnR, CueR is an HTH-type transcriptional regulator. CueR is also located immediately upstream of the nrgA (ammonium transporter) gene and shares the same bidirectional transporter.

[0151] In many bacterial species, CueR is generally recognized as a regulator of the Cue copper efflux system, activating gene expression in response to high levels of intracellular copper. In Paenibacillus polymyxa, the CueR ORF shares a bidirectional promoter with the ammonium transporter NrgA. CueR, like GlnR, is an HTH-type transcriptional regulator, and its proximity to NrgA in Paenibacillus polymyxa suggests that it may also be involved in the transcription of the ammonium transporter.

[0152] orf1 In the native nif cluster of Paenibacillus odorifer strain 17899, the orf1 gene overlaps the downstream sequence of nifX with the first 17 nucleotides of orf1.

[0153] P-II gene and glnB The protein encoded by glnB is a P-II protein that transduces the nitrogen status of the cell and indirectly affects the expression of nitrogen assimilation genes in some bacteria.

[0154] nifB The protein encoded by nifB, the FeMo cofactor biosynthesis protein, acts as a molecular scaffold to produce iron-sulfur clusters, which are cofactors for nitrogenase activity.

[0155] nifS The protein encoded by nifS is a cysteine ​​desulfurase that removes elemental sulfur from cysteine ​​for donation to the iron-sulfur cluster required for nitrogenase activity.

[0156] nifK The protein encoded by nifK is one subunit of dinitrogenase that contains the molybdenum-iron catalytic site for nitrogen fixation together with NifD.

[0157] nifD The protein encoded by nifD is one subunit of dinitrogenase that contains the molybdenum-iron catalytic site for nitrogen fixation together with NifK.

[0158] nifX The NifX protein is known to bind to NifB-co and to be involved in NifB-co translocation.

[0159] nifS The protein encoded by the nifS gene is a putative cysteine ​​desulfurase, NifS.

[0160] nifE and nifN The proteins encoded by nifE and nifN constitute the iron-molybdenum cofactor (FeMo-Co), which is important for nitrogen fixation. The FeMo-Co complex binds to the active site (nifB), where dinitrogen is converted to ammonia. NifEN is a 200 kDa α2β2 heterotetramer containing an [Fe-S] cluster. NifEN function is essential for FeMo-Co biosynthesis. Due to the amino acid sequence similarity between NifEN and NifDK and the observation that NifDK was not required for FeMo-Co biosynthesis, it has been proposed that NifEN may be a molecular scaffold for assembling FeMo-Co.

[0161] hesA The HesA protein is encoded by two different genes, hesA1 (heterois) and hesA2 (trophic), and is a shuttle for transporting sulfur and molybdenum cofactors to the NifHDKEN complex for FeMoco synthesis and maturation.

[0162] anf gene The anf nuclease is a nitrogenase iron-iron protein with a hexameric subunit structure containing two alpha subunits, two beta subunits, and two gamma subunits.

[0163] The protein encoded by anfG is the delta subunit of the dinitrogenase enzyme, which utilizes only iron as a cofactor.

[0164] The protein encoded by anfD is the alpha subunit of the dinitrogenase enzyme, which utilizes only iron as a cofactor.

[0165] The protein encoded by anfK is the beta subunit of the dinitrogenase enzyme, which utilizes only iron as a cofactor.

[0166] vnf gene The protein encoded by vnfA is a transcriptional regulator that activates the expression of the vnf genes required for producing vanadium-dependent nitrogenase.

[0167] The protein encoded by vnfD is the alpha subunit of vanadium-dependent dinitrogenase.

[0168] Microbial Consortium In aspects, the present disclosure provides a microbial consortium comprising a combination of at least any two microorganisms, one of which is a Paenibacillus strain listed in Table 1. In some embodiments, the Paenibacillus strain comprises a polynucleotide sequence that shares at least 90% identity with any one or more of SEQ ID NOs: 1-293. In some embodiments, the Paenibacillus strain is a species selected from the group consisting of albidus, amylolyticus, anaericanus, azotifigens, borealis, chondroitinus, donghaensis, durus, graminis, helianthi, jilunlii, macerans, odorifer, panacisoli, peoriae, phoenicis, phytohabitans, polymyxa, rhizoplanae, silagei, sonchi, sp000159955, sp000758525, sp000758605, sp001517085, sp001955925, taohuashanense, thermophilus, tritici, typhae, wynnii, xylanexedens, and yonginensis. In some embodiments, the Paenibacillus strain is of subgroup I. In some embodiments, the Paenibacillus strain is of subgroup II.

[0169] In certain embodiments, a consortium of the present disclosure includes two, three, four, five, six, seven, eight, nine, ten, or more microorganisms, wherein the microorganisms of the consortium are different microbial species or different strains of a microbial species.

[0170] Microbial production composition In some cases, a microorganism of the present disclosure may produce one or more compounds and / or may have one or more activities, for example, one or more of: production of a metabolite, production of a plant hormone such as an 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 a protease or an organic acid or a lipopeptide or a polynucleotide or a polypeptide, nitrogen fixation, phosphate mineral solubilization, or any combination and / or plurality of the foregoing.

[0171] For example, the microorganisms of the present disclosure may produce a plant hormone selected from the group consisting of auxin, cytokinin, gibberellin, ethylene, brassinosteroids, and abscisic acid.

[0172] Thus, "metabolites produced" by the microorganisms of the present disclosure are intended to refer to any molecules (such as small molecules, vitamins, minerals, proteins, nucleic acids, lipids, fats, carbohydrates, etc.) produced by the microorganisms. The exact mechanism by which the microorganisms of the present disclosure confer beneficial traits to a given plant species is often unknown. In some instances, it is hypothesized that the microorganisms produce metabolic products that are beneficial to the plant. Thus, in some embodiments, a cell-free or inactivated preparation of a microorganism is beneficial to a plant because the microorganism need not be viable to confer beneficial traits to a given plant species, as long as the preparation is produced by the microorganism and contains metabolic products that are beneficial to the plant.

[0173] In one embodiment, the microorganisms of the present disclosure can produce auxin (e.g., indole-3-acetic acid (IAA)). Auxin production can be assayed. Many of the microorganisms described herein can be capable of producing the plant hormone auxin, indole-3-acetic acid (IAA), when grown in culture. Auxin plays an important role in altering plant physiology, including the extent of root growth.

[0174] Thus, in one embodiment, the microorganisms of the present disclosure are present as a population located on the surface or within the tissues of a given plant species. The microorganisms may produce a composition, such as a metabolite, in an amount effective to cause a detectable increase in the amount of the composition found on or within the plant compared to a reference plant that has not been treated with the microorganisms of the present disclosure or a cell-free or inert preparation. The composition produced by the microbial population may be beneficial to the plant species.

[0175] Such microbially produced compositions may be present in the cell culture broth or medium in which the microorganisms grow, or may include exudates produced by the microorganisms. As used herein, "exudate" refers to one or more compositions excreted by or extracted from one or more microbial cells. As used herein, "broth" refers to the aggregate composition of the cell culture medium after microbial cells have been placed in the medium. The composition of the broth may change over time during different stages of microbial growth and / or development. Broths and / or exudates may improve the traits of the plants with which they are associated. Microbial-induced traits in plants

[0176] The present disclosure utilizes microorganisms to impart beneficial properties (or beneficial traits) to desirable plant species, such as agronomic species of interest. In this disclosure, the terms "beneficial property," "beneficial trait," or "trait of interest" are used interchangeably to refer to a phenotype or genetic characteristic of a desired plant of interest that is modulated by application of a microorganism or microbial consortium described herein. As noted above, in some embodiments, it is highly likely that a metabolic product produced by a given microorganism is ultimately responsible for modulating or imparting a beneficial trait to a given plant.

[0177] There are numerous beneficial traits that can be modulated by application of the microorganisms of the present disclosure. For example, the microorganisms may have the ability to confer one or more beneficial properties to a plant species, such as enhanced growth, increased yield, increased nitrogen use efficiency, increased stress tolerance, increased drought tolerance, increased photosynthetic rate, improved water use efficiency, increased pathogen resistance, modification of plant architecture that does not necessarily affect plant yield but rather is related to plant functionality, increasing the production of a metabolite of interest in the plant, etc.

[0178] In aspects, the microorganisms taught herein provide a wide range of agricultural applications, including improved grain, fruit, and flower yield, improved growth of plant parts, improved ability to utilize nutrients (e.g., nitrogen, phosphate, and the like), improved disease resistance, bio-pesticidal effects including improved resistance to fungi, insects, and / or nematodes, improved survivability in extreme climates, and improved phenotypic characteristics of other desirable plants.

[0179] In some embodiments, the genetically modified plant relative to a reference plant may exhibit 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, improved growth, improved health, heat tolerance, herbicide tolerance, herbivore resistance, improved nitrogen fixation, improved nitrogen utilization, improved nutrient utilization (e.g., phosphate, potassium, etc.), 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, grain mass, grain moisture content, metal tolerance, number of ears, number of grains per ear, number of pods, nutritional enhancement, pathogen resistance (e.g., to impair pathogen survival), The isolated microorganisms, consortia, and / or agricultural compositions of the present disclosure can be applied to plants to regulate or modify plant characteristics such as reduced pathogen levels (via excretion of metabolites), pest resistance, improved photosynthetic capacity, salt tolerance, greening, improved plant vigor, increased mature seed dry weight, increased mature seed fresh weight, increased number of mature seeds per plant, increased chlorophyll content, increased number of pods per plant, increased pod length 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, detectable modulation of metabolite levels, detectable modulation of transcript levels, and detectable modulation of the proteome.

[0180] In some embodiments, the isolated microorganisms, consortia, and / or agricultural compositions of the present disclosure can be applied to plants to negatively regulate certain plant characteristics. For example, in some embodiments, the microorganisms of the present disclosure can reduce a phenotypic trait of interest, as this functionality may be desirable in some applications. For example, the microorganisms of the present disclosure may have the ability to reduce root growth or reduce root length. Or, the microorganisms may have the ability to reduce shoot growth or slow the rate at which a plant grows, as these modulations of plant traits may be desirable in certain applications.

[0181] In some embodiments, the isolated microorganisms, consortia, and / or agricultural compositions of the present disclosure can be applied to plants to confer resistance to nematode stress to the plants.

[0182] In some embodiments, the isolated microorganisms, consortia, and / or agricultural compositions of the present disclosure can be applied to plants to provide a biostimulant effect to the plants, hi some embodiments, the isolated microorganisms, consortia, and / or agricultural compositions of the present disclosure can be applied to plants to provide disease resistance to the plants.

[0183] Agricultural composition In some embodiments, the microorganisms of the present disclosure are combined with agricultural compositions. Agricultural compositions generally refer to organic and inorganic compounds, which may include compositions that promote the cultivation of microorganisms and / or plant elements; compositions involved in formulating microorganisms for application to plant elements (such as, but not limited to, wetting agents, compatibilizers (also referred to as "compatibilizers"), antifoaming agents, detergents, sequestering agents, drift reducing agents, neutralizing agents and buffers, corrosion inhibitors, dyes, odorants, spreading agents (also referred to as "spreading agents"), penetration aids (also referred to as "penetrating agents"), adhesives (also referred to as "stickers" or "binders"), dispersants, thickeners (also referred to as "thickeners"), stabilizers, emulsifiers, freezing point depressants, antimicrobial agents, etc.); compositions involved in providing protection to plant elements or plants (such as, but not limited to, insecticides, nematicides, fungicides, bactericides, herbicides, etc.), and other compositions that may be of interest for specific applications.

[0184] In some embodiments, the agricultural composition of the present disclosure is a solid. When a solid composition is used, it may be desirable to include one or more carrier materials with the isolated active microorganisms or consortia. In some embodiments, the present disclosure teaches the use of carriers including, but not limited to, silica, silica gel, silicates, talc, kaolin, attaclay, limestone, chalk, loess, clay, dolomite, diatomaceous earth, mineral earths such as calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, thiourea, and urea, vegetable-derived products such as cereals, bark, wood, and nut shells, cellulose powder, attapulgite, montmorillonite, mica, vermiculite, synthetic silica, and synthetic calcium silicate, or compositions thereof.

[0185] growth composition In some embodiments, a growth and development promoting composition is provided to the microorganisms and / or plant elements. Exemplary compositions include liquids (broths, media, etc.) and / or solids (soil, nutrients, etc.). Various organic or inorganic compounds, alone or in combination with plant elements, such as, but not limited to, amino acids, vitamins, minerals, carbohydrates, simple sugars, lipids, can be added to the growth composition to promote the health of the microorganisms.

[0186] Pharmaceutical Composition One or more compositions may be combined in addition to the microorganism or composition made from the microorganism for various use, stability, activity, and / or storage reasons. The additional compositions may be referred to as "formulation components."

[0187] In some embodiments, the agricultural compositions disclosed herein may be formulated as a liquid, solid, gas, or gel.

[0188] Thus, in some embodiments, the present disclosure teaches that the agricultural compositions disclosed herein can include compounds or salts such as monoethanolamine salts, 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, sodium ammonium hydrogen phosphate, ammonium thiocyanate, ammonium sulfamate, or ammonium carbamate.

[0189] In some embodiments, the present disclosure teaches that agricultural compositions can include binders such as polyvinylpyrrolidone, polyvinyl alcohol, partially hydrolyzed polyvinyl acetate, carboxymethyl cellulose, starch, vinylpyrrolidone / vinyl acetate copolymers and polyvinyl acetate, or compositions thereof; lubricants such as magnesium stearate, sodium stearate, talc, or polyethylene glycol, or compositions thereof; antifoaming agents such as silicone emulsions, long chain alcohols, phosphate esters, acetylenic 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 thereof.

[0190] In some embodiments, the agricultural composition comprises a surfactant. In some embodiments, the surfactant is added to a liquid agricultural composition. In other embodiments, the surfactant is added to a solid formulation, particularly a solid formulation designed to be diluted with a carrier before application. Thus, in some embodiments, the agricultural composition comprises a surfactant. Surfactants may be used alone or with other additives, such as mineral or vegetable oils, as adjuvants to spray tank mixtures to improve the biological performance of microorganisms on targets. The type of surfactant used for bioaugmentation generally depends on the nature and mode of action of the microorganism. Surfactants can be anionic, cationic, or nonionic in nature and can be employed as emulsifiers, wetting agents, suspending agents, or for other purposes. In some embodiments, the surfactant is a nonionic material, such as alkyl ethoxylates, linear fatty alcohol ethoxylates, and fatty amine ethoxylates. Surfactants conventionally used in the formulation art and which may be used in the present formulations are described in McCutcheon's Detergents and Emulsifiers Annual, MC Publishing Corp., Ridgewood, NJ, 1998 and Encyclopedia of Surfactants, Vol. I-III, Chemical Publishing Co., New York, 1980-81.In some embodiments, the present disclosure provides alkali metal, alkaline earth metal, or ammonium salts of aromatic sulfonic acids, such as lignosulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid, and dibutylnaphthalenesulfonic acid, as well as alkali metal, alkaline earth metal, or ammonium salts of fatty acids, alkyl ethers, lauryl ethers, fatty alcohol sulfates, and fatty alcohol glycol ether sulfates of arylsulfonic acids; condensates of sulfonated naphthalene with formaldehyde and derivatives thereof; condensates of phenol and formaldehyde with naphthalene or naphthalenesulfonic acid; condensates of formaldehyde with phenol or phenolsulfonic acid; condensation product of phenol with formaldehyde and sodium sulfite, polyoxyethylene octylphenyl ether, ethoxylated isooctylphenol, ethoxylated octylphenyl ether, or ethoxylated nonylphenol, tributylphenyl polyglycol ether, alkylaryl polyether alcohol, isotridecyl alcohol, ethoxylated castor oil, ethoxylated triarylphenol, salt of phosphoric acid-containing triarylphenol ethoxylate, lauryl alcohol polyglycol ether acetate, sorbitol ester, lignin sulfite waste liquor, or methylcellulose, or a composition thereof.

[0191] In some embodiments, the present disclosure provides salts of alkyl sulfates such as diethanolammonium lauryl sulfate, alkylaryl sulfonates such as calcium dodecylbenzene sulfonate, alkylphenol-alkylene oxide adducts such as nonylphenol-C18 ethoxylate, alcohol-alkylene oxide adducts such as tridecyl alcohol-C16 ethoxylate, soaps such as sodium stearate, alkylnaphthalene-sulfonates such as sodium dibutyl-naphthalene sulfonate, dialkyl esters of sulfosuccinates such as sodium di(2-ethylhexyl) sulfosuccinate. Other suitable surfactants are taught, including esters, sorbitol esters such as sorbitol oleate, quaternary amines such as lauryltrimethylammonium chloride, polyethylene glycol esters of fatty acids such as polyethylene glycol stearate, block copolymers of ethylene oxide and propylene oxide, salts of mono- and di-alkyl 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, particularly the methyl esters, of the above vegetable oils.

[0192] In some embodiments, the agricultural composition includes a wetting agent. 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 agricultural chemical formulations: to increase the wetting rate of powders in water during processing and manufacturing to create concentrates for soluble liquids or suspension concentrates, and to reduce the wetting time of wettable powders and improve water penetration into water-dispersible granules during mixing of the product with water in a spray tank or other container. In some embodiments, examples of wetting agents used in the agricultural compositions of the present disclosure, including wettable powders, suspension concentrates, and water-dispersible granules, are sodium lauryl sulfate, dioctyl sodium sulfonate, alkylphenol ethoxylates, and fatty alcohol ethoxylates.

[0193] In some embodiments, the agricultural composition of the present disclosure includes a dispersant. A dispersant is a substance that adsorbs to the surface of particles and helps maintain the dispersion of the particles and prevent them from reagglomerating. In some embodiments, dispersants are added to the agricultural composition of the present disclosure to facilitate dispersion and suspension during manufacturing and to ensure that the particles redisperse in water in the spray tank. In some embodiments, dispersants are used in wettable powders, suspension concentrates, and water-dispersible granules. Surfactants used as dispersants have the ability to strongly adsorb to particle surfaces and provide a charge or steric barrier against particle reagglomeration. In some embodiments, the most commonly used surfactants are anionic, nonionic, or a mixture of the two types.

[0194] In some embodiments of wettable powder formulations, the most common dispersants are sodium lignosulfonates. In some embodiments, suspension concentrates use polyelectrolytes such as sodium naphthalene sulfonate formaldehyde condensates to provide excellent adsorption and stabilization. In some embodiments, tristyrylphenol ethoxylate phosphate esters are also used. In some embodiments, alkylarylethylene oxide condensates and EO-PO block copolymers may be combined with anionic surfactants as dispersants in suspension concentrates.

[0195] In some embodiments, the agricultural compositions of the present disclosure include a polymeric surfactant. In some embodiments, the polymeric surfactant has a very long hydrophobic "backbone" and many ethylene oxide chains, forming the "teeth" of a "comb" surfactant. In some embodiments, these high molecular weight polymers can impart very good long-term stability to suspension concentrates because the hydrophobic backbone has many anchoring points on the particle surface. In some embodiments, examples of dispersants used in the agricultural compositions of the present disclosure include sodium lignosulfonate, sodium naphthalenesulfonate formaldehyde condensate, tristyrylphenol ethoxylate phosphate ester, fatty alcohol ethoxylate, alkyl ethoxylate, EO-PO block copolymer, and graft copolymer.

[0196] In some embodiments, the agricultural compositions of the present disclosure contain an emulsifier. An emulsifier is a substance that stabilizes the suspension of droplets of one liquid phase in another. Without an emulsifier, the two liquids would separate into two immiscible liquid phases. In some embodiments, the most commonly used emulsifier mixtures include an alkylphenol or aliphatic alcohol having 12 or more ethylene oxide units and an oil-soluble calcium salt of dodecylbenzenesulfonic acid. A hydrophile-lipophile balance (HLB) value in the range of 8 to 18 will usually provide a stable emulsion. In some embodiments, emulsion stability can be improved by the addition of a small amount of an EO-PO block copolymer surfactant.

[0197] In some embodiments, the agricultural compositions of the present disclosure include a solubilizing agent. A solubilizing agent is a surfactant that will form micelles in water at concentrations above the critical micelle concentration. The micelles can then dissolve or solubilize water-insoluble substances inside the hydrophobic portion of the micelle. The types of surfactants commonly used for solubilization are nonionic substances: sorbitan monooleate, sorbitan monooleate ethoxylate, and methyl oleate.

[0198] In some embodiments, the agricultural compositions of the present disclosure include an organic solvent. Organic solvents are primarily used in the formulation of emulsifiable concentrates, ULV formulations, and, to a lesser extent, granular formulations. Sometimes, solvent mixtures are used. In some embodiments, the present disclosure teaches the use of solvents including aliphatic paraffin oils, such as kerosene or refined paraffin. In other embodiments, the present disclosure teaches the use of aromatic solvents, such as xylene and the high molecular weight fractions of C9 and C10 aromatic solvents. In some embodiments, chlorinated hydrocarbons are useful as cosolvents to prevent crystallization of the formulation when the anti-pest agent is emulsified in water. Alcohols may be used as cosolvents to increase solvency.

[0199] In some embodiments, agricultural compositions include a gelling agent. Thickeners or gelling agents are primarily used in the formulation of suspension concentrates, emulsions, and suspoemulsions to modify the rheological or flow properties of the liquid and prevent separation and settling of dispersed particles or droplets. Thickeners, gelling agents, and anti-settling agents are broadly divided into two categories: water-insoluble particulates and water-soluble polymers. Clay and silica can be used to create suspension concentrate formulations. In some embodiments, agricultural compositions include one or more thickening agents, 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 most commonly used types of polysaccharides 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 not limited to, guar gum, locust bean gum, carrageenan, alginate, methylcellulose, sodium carboxymethylcellulose (SCMC), and hydroxyethylcellulose (HEC). In some embodiments, the present disclosure teaches the use of other types of anti-settling agents, such as modified starch, polyacrylic acid, polyvinyl alcohol, and polyethylene oxide. Another good anti-settling agent is xanthan gum.

[0200] In some embodiments, the presence of a surfactant that reduces interfacial tension can cause the aqueous formulation to foam during the mixing process in production and application through a spray tank. Therefore, in some embodiments, an antifoaming agent is often added either during the production stage or before filling into the bottle / spray tank to reduce the tendency to foam. There are generally two types of antifoaming agents: silicone antifoaming agents and non-silicone antifoaming agents. Silicones are usually aqueous emulsions of dimethylpolysiloxane, while non-silicone antifoaming agents are water-insoluble oils such as octanol and nonanol, or silica. In both cases, the function of the antifoaming agent is to displace the surfactant from the air-water interface.

[0201] In some embodiments, the agricultural composition comprises a preservative.

[0202] In some embodiments, the agricultural composition may be formulated as a soil drench, foliar spray, dip treatment, in-furrow treatment, soil amendment, granule, broad-spectrum treatment, post-harvest disease control treatment, or seed treatment. In some embodiments, the agricultural composition may be applied alone or in a rotational application program with other agricultural products.

[0203] 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 in ground, aerial, and irrigation applications.

[0204] In some embodiments, the agricultural composition may be applied to genetically modified seeds or plants.

[0213] In some embodiments, the present invention teaches the synergistic use of a microorganism, or microbial consortium, of the present disclosure with known pesticides in agricultural spaces, such as herbicides, fungicides, fungicides, insecticides, virucides, miticides, nematicides, acaricides, rodenticides, and / or algaecides.

[0214] In some embodiments, the present invention teaches the synergistic use of the microorganisms, or microbial consortia, of the present disclosure with known pesticides in agricultural spaces, such as biopesticides that function as herbicides, bactericides, fungicides, insecticides, virucides, acaricides, nematicides, miticides, rodenticides, and / or algaecides.

[0215] In some embodiments, when a microorganism or microbial consortium identified according to the methods taught is combined with a pesticide, an additive effect on the plant phenotypic trait of interest is observed. In other embodiments, when a microorganism or microbial consortium identified according to the methods taught is combined with a pesticide, a synergistic effect on the plant phenotypic trait of interest is observed.

[0220] In some embodiments, the agricultural compositions of the present disclosure include plant growth regulators and / or biostimulants used in combination with the microorganisms of the present teachings.

[0221] In some embodiments, individual microorganisms, or microbial consortia, or microbial communities developed according to the methods of the present disclosure can be combined with known plant growth regulators in the agricultural space, such as auxins, gibberellins, cytokinins, ethylene generators, growth inhibitors, and growth retardants.

[0222] For example, in some embodiments, the present disclosure teaches agricultural compositions comprising one or more of the following active ingredients: ancymidol, butralin, alcohol, chloromequat chloride, cytokinin, daminozide, etepohon, flurpurmidol, gibberellic acid, gibberellin mixtures, indole-3-butyric acid (IBA), maleic hydrazide, mefluidide, mepiquat chloride, mepiquat pentaborate, naphthaleneacetic acid (NAA), 1-napthaleneacetemide (NAD), n-decanol, placlobutrazol, prohexadione calcium, trinexapac-ethyl, uniconazole, salicylic acid, abscisic acid, ethylene, brassinosteroids, jasmonates, polyamines, nitric oxide, strigolactone, or karrikin, among others.

[0226] In some embodiments, the present invention teaches the synergistic use of a microorganism or microbial consortium of the present disclosure with a plant growth regulator and / or plant growth stimulant, such as a plant hormone or chemical that affects the production or disruption of a plant growth regulator.

[0227] In some embodiments, the present invention teaches that plant hormones can include auxins (e.g., indole acetic acid IAA), gibberellins, cytokinins (e.g., kinetin), abscisic acid, ethylene (and its production regulated by ACC synthase and disrupted by ACC deaminase).

[0228] In some embodiments, individual microorganisms, or microbial consortia or communities developed according to the disclosed methods can be combined with biostimulants, which can be, but are not limited to, microorganisms, plant extracts, seaweed, acids, biochar, etc.

[0229] In some embodiments, individual microorganisms, or microbial consortia, or microbial communities developed according to the disclosed methods can be combined with fertilizer, which can be organic (e.g., compost, blood, fish, etc.), nitrogenous (e.g., nitrate, ammonium, urea, etc.), phosphate, and potassium. Such fertilizers can also contain micronutrients, including, but not limited to, sulfur, iron, zinc, etc.

[0230] In some embodiments, the present invention teaches additional plant growth-promoting chemicals such as humic acid, fulvic acid, amino acids, polyphenols, and protein hydrolysates that can act synergistically with the microorganisms and microbial consortia disclosed herein.

[0231] Thus, in some embodiments, the present disclosure provides for applying a microorganism of the present teachings in combination with Ascend® to any crop. Further, the present disclosure provides for applying a microorganism of the present teachings in combination with Ascend® to any crop using any method or application rate.

[0232] In some embodiments, the present disclosure teaches agricultural compositions comprising biostimulants.

[0233] 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 growth media.

[0234] The level of microorganisms in the soil or growing medium directly correlates with plant health. Because microorganisms feed on biodegradable carbon sources, plant health also correlates with the amount of organic matter in the soil. While fertilizers provide nutrients to nourish and grow plants, in some embodiments, biostimulants provide biodegradable carbon, e.g., molasses, carbohydrates, e.g., sugars, to nourish and grow microorganisms. Unless otherwise expressly stated, biostimulants may include a single component or a combination of several different components that can enhance microbial activity or plant growth and development due to one or more of the components acting independently or in combination.

[0235] In some embodiments, biostimulants are compounds that generate non-nutritional plant growth responses. In some embodiments, many of the important benefits of biostimulants are based on their ability to affect hormonal activity. Plant hormones (phytohormones) are chemical messengers that regulate normal plant development and responses to the environment. Root and shoot growth, as well as other growth responses, are regulated by plant hormones. In some embodiments, compounds in biostimulants can alter the hormonal status of plants and have a significant impact on the growth and health of the plants. Thus, in some embodiments, the present disclosure teaches sea kelp, humic acid, fulvic acid, and B vitamins as common components of biostimulants. In some embodiments, the biostimulants of the present disclosure enhance antioxidant activity, thereby improving the plant's defense system. In some embodiments, antioxidants included in biostimulants include vitamin C, vitamin E, and amino acids such as glycine.

[0236] In other embodiments, biostimulants can act to stimulate the growth of microorganisms present in soil or other plant growth media. Previous studies have shown that certain biostimulants, including certain organic seed extracts (e.g., soybeans), can stimulate the growth of microorganisms contained in a microbial inoculant when used in combination with the inoculant. Thus, in some embodiments, the present disclosure teaches one or more biostimulants that, when used in conjunction with a microbial inoculant, can enhance the populations of both indigenous and inoculant microorganisms. For a review of some common uses of biostimulants, see Calvo et al., 2014, Plant Soil 383:3-41. Combinations of plant elements, microorganisms, and agricultural compositions

[0237] In some embodiments, the present disclosure teaches that individual microorganisms, or microbial consortia, or microbial communities, including any one or more microorganisms, including, for example, one or more Paenibacillus strains described herein, or any combination of the foregoing, optionally in combination with any agricultural composition, can be applied to plant elements for improvement of plant phenotype.

[0238] Isolated microorganisms or communities or consortia (generally, interchangeably, "microbes" or "microbes") may be applied to heterologous plant elements to create synthetic combinations. A microorganism is considered heterologous to a plant element if it is not normally associated with the plant element in nature, or if found at all, is applied in an amount different from that found in nature. In some embodiments, a microorganism may be naturally found in one part of a plant but not another, and the introduction of the microorganism into another part of the plant is considered a heterologous association.

[0239] It is contemplated that the microorganisms, either isolated or associated with plants or plant components, may be further associated with one or more agricultural compositions as described above.

[0240] Synthetic combinations of microorganisms and plant elements, microorganisms and agricultural compositions, and microorganisms and plant elements and agricultural compositions are contemplated (generally "synthetic compositions," which are compositions that include components not typically found in nature).

[0241] Plant Element Processing In some embodiments, the present disclosure also relates to the discovery that treating plant elements with one or more combinations of the microorganisms or agricultural compositions of the present disclosure before sowing or planting the plant elements can enhance desirable traits in the plant, such as plant growth, plant health, and / or plant resistance to pests and diseases.

[0242] Thus, in some embodiments, the present disclosure teaches the use of one or more microorganisms or microbial consortia as a plant element treatment. The plant element treatment can be a plant element coating applied directly to untreated and "bare" plant elements. However, the plant element treatment can also be a plant element protective film applied to plant elements that have already been coated with one or more previous plant element coatings or plant element treatments. The previous plant element treatments can include one or more active compounds, chemical or biological, and one or more inactive ingredients.

[0243] The term "plant element treatment" generally refers to the application of a substance to plant elements before or while the plant elements are planted in soil. Treating plant elements with the microorganisms and other agricultural compositions of the present disclosure has the advantage that the treatment occurs at the site where the plant elements will be planted shortly before the plant elements germinate and emerge.

[0244] In other embodiments, the present disclosure also teaches that the use of plant element treatments minimizes the amount of microorganisms or agricultural compositions required to successfully treat plants, and further limits worker contact with the microorganisms and compositions compared to application techniques such as application to the soil or application to emerged plant elements.

[0245] Additionally, in some embodiments, the present disclosure teaches that the microorganisms disclosed herein are important for enhancing the early stages of plant life (e.g., the first 30 days after emergence of plant elements). Thus, in some embodiments, delivery of the microorganisms and / or compositions of the present disclosure as plant element treatments positions the microorganisms at the site of action at a time critical for their activity.

[0246] In some embodiments, the microbial compositions of the present disclosure are formulated as plant element treatments. In some embodiments, it is believed that plant elements can be substantially uniformly coated with one or more of the microbial and / or agricultural compositions disclosed herein using conventional mixing, spraying, or a combination of these methods through the use of treatment application equipment specifically designed and manufactured to accurately, safely, and efficiently coat plant elements with the plant element treatment product. Such equipment uses various types of coating technologies, such as rotary coaters, drum coaters, fluidized bed technology, spouted beds, rotary misters, or combinations thereof. Liquid plant element treatments, such as those disclosed herein, can be applied through either a spinning "atomizer" disk or a spray nozzle, which distributes the plant element treatment evenly over the plant elements as it moves through the spray pattern. In some embodiments, the plant elements are then mixed or rolled for an additional period to further distribute the treatment and dry.

[0247] The plant elements may or may not be germinated before being coated with the microbial composition to increase uniformity of germination and seedling emergence. In an alternative embodiment, the dry powder formulation can be metered and sprinkled onto the moving plant elements and mixed until the dry powder formulation is completely distributed.

[0248] In some embodiments, a plant element has at least a portion of its surface area coated with a microbiological composition according to the present disclosure. In some embodiments, a plant element coating comprising a microbial composition is applied directly to a bare plant element. In some embodiments, a plant element protective film comprising a microbial composition is applied to a plant element already having a plant element coating applied thereon. In some aspects, a plant element can have a plant element coating comprising, for example, clothianidin and / or Bacillus firmus I-1582, onto which the present composition will be applied as a plant element protective film. In some aspects, a microbial composition of the present teachings is applied as a plant element protective film to a plant element that has already been treated with PONCHO™ VOTiVO™. In some aspects, a plant element can have a plant element coating comprising, for example, metalaxyl, and / or clothianidin, and / or Bacillus firmus I-1582, onto which the present composition will be applied as a plant element protective film. In some embodiments, the microbial composition of the present teachings is applied as a protective coating to plant elements that have already been treated with ACCELERON™.

[0249] In some embodiments, the plant elements treated with the microorganisms have a microbial spore concentration or microbial cell concentration of about 10^2 to 10^12, 10^2 to 10^11, 10^2 to 10^10, 10^2 to 10^9, 1^02 to 10^8, 10^2 to 10^7, 10^2 to 10^6, 10^2 to 10^5, 10^2 to 10^4, or 10^2 to 10^3 per plant element.

[0250] In some embodiments, the plant elements treated with the microorganisms have a microbial spore concentration or microbial cell concentration of about 10^3 to 10^12, 10^3 to 10^11, 10^3 to 10^10, 10^3 to 10^9, 10^3 to 10^8, 10^3 to 10^7, 10^3 to 10^6, 10^3 to 10^5, or 10^3 to 10^4 per plant element.

[0251] In some embodiments, the plant elements treated with the microorganisms have a microbial spore or microbial cell concentration of about 10^4 to 10^12, 10^4 to 10^11, 10^4 to 10^10, 10^4 to 10^9, 10^4 to 10^8, 10^4 to 10^7, 10^4 to 10^6, or 10^4 to 10^5 per plant element.

[0252] In some embodiments, the plant elements treated with the microorganisms have a microbial spore or microbial cell concentration of about 10^5 to 10^12, 10^5 to 10^11, 10^5 to 10^10, 10^5 to 10^9, 10^5 to 10^8, 10^5 to 10^7, or 10^5 to 10^6 per plant element.

[0253] In some embodiments, the microbially treated plant elements have a microbial spore concentration or microbial cell concentration of about 10^5 to 10^9 per plant element.

[0254] In some embodiments, the plant elements treated with the microorganisms have a microbial spore or microbial cell concentration of at least about 1x10^3, or 1x10^4, or 1x10^5, or 1x10^6, or 1x10^7, or 1x10^8, or 1x10^9 per plant element.

[0255] In some embodiments, the amount of one or more of the microorganisms and / or agricultural compositions applied to the plant elements depends on the final formulation and the size or type of plant or plant element being utilized. In some embodiments, one or more of the microorganisms are present in an amount of from about 2% w / w to about 80% w / w of the total formulation. In some embodiments, one or more of the microorganisms employed in the composition is from about 5% w / w to about 65% w / w or from 10% w / w to about 60% w / w by weight of the total formulation.

[0256] In some embodiments, the plant elements may also have more spores or microbial cells per plant element, such as, for example, about 10^2, 10^3, 10^4, 10^5, 10^6, 10^7, 10^8, 10^9, 10^10, 10^11, 10^12, 10^13, 10^14, 10^15, 10^16, or 10^17 spores or cells per plant element.

[0258] In some embodiments, the plant element coating of the present disclosure can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm thick.

[0259] In some embodiments, the plant element coating of the present disclosure comprises 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% of the weight of the uncoated plant element. ,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%.

[0260] In some embodiments, the microbial spores and / or cells can be coated freely onto the plant elements, or can be formulated in a liquid or solid composition before being coated onto the plant elements. For example, a solid composition containing the microorganisms can be prepared by mixing a solid carrier with a spore or cell suspension until the solid carrier is impregnated with the spore or cell suspension. This mixture can then be dried to obtain the desired particles.

[0261] In some other embodiments, the solid or liquid microbial compositions of the present disclosure are contemplated to further contain functional agents, such as activated carbon, nutrients (fertilizers), and other agents capable of improving the germination and quality of the produce, or combinations thereof.

[0262] Plant element coating methods and compositions 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, for example, in U.S. Patent Nos. 5,916,029, 5,918,413, 5,554,445, 5,389,399, 4,759,945, 4,465,017, and U.S. Patent Application No. 13 / 260,310, each of which is incorporated herein by reference.

[0268] Various additives, such as adhesives, dispersants, surfactants, and nutrients and buffering components, 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, a solid, or a dry powder. Dry powders can be derived from various materials, such as calcium carbonate, gypsum, vermiculite, talc, humus, activated carbon, and various phosphorus compounds.

[0269] In some embodiments, the plant element coating composition can include at least one filler, which is an organic or inorganic, natural or synthetic component, with which the active ingredient is combined to facilitate its application to the plant element. In an aspect, the filler is an inert solid such as a clay, a natural or synthetic silicate, silica, a resin, a wax, a solid fertilizer (e.g., an ammonium salt), a natural earth mineral such as kaolin, clay, talc, lime, quartz, attapulgite, montmorillonite, bentonite, or diatomaceous earth, or a synthetic mineral such as silica, alumina, or a silicate, particularly aluminum silicate or magnesium silicate.

[0270] In some embodiments, the plant element treatment agent may contain the following ingredients: other insecticides, including compounds that act only below ground; fungicides, such as captan, thiram, metalaxyl, fludioxonil, oxadixyl, and isomers of each of these materials; herbicides, including compounds selected from glyphosate, carbamates, thiocarbamates, acetamides, triazines, dinitroanilines, glycerol ethers, pyridazinones, uracils, phenoxy, urea, and benzoic acid; benzoxazines, benzhydryl derivatives, N,N - herbicide antidotes such as diallyldichloroacetamide, various dihaloacyl, oxazolidinyl and thiazolinyl 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 can be added as a separate layer on the plant element, or alternatively, can be added as part of the plant element coating composition of the present disclosure.

[0271] In some embodiments, the formulations used to treat plant elements of the present disclosure can be in the form of suspensions, emulsions, slurries of particles in an aqueous medium (e.g., water), wettable powders, wettable granules (dry flowable), and dry granules. When formulated as a suspension or slurry, the concentration of the active ingredient in the formulation can be from about 0.5% to about 99% by weight (w / w), or 5-40%, or as otherwise formulated by one of skill in the art.

[0272] As noted above, other conventional non-active or inactive ingredients can be incorporated into the formulation. Such inactive ingredients include, but are not limited to, conventional adhesives, e.g., dispersants such as methylcellulose, which act as hybrid dispersants / adhesives for use in treating plant elements, 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, etc. Additional inactive ingredients useful in the present disclosure can be found in McCutcheon's, Vol. 1, "Emulsifiers and Detergents," MC Publishing Company, Glen Rock, NJ, USA, 1996, incorporated herein by reference.

[0273] The plant element coating formulations of the present disclosure can be applied to the plant elements by a variety of methods, including, but not limited to, mixing in a container (e.g., a bottle or bag), mechanical dusting, tumbling, spraying, and dipping. A variety of active or inactive materials can be used to contact the plant elements with the microbial compositions according to the present disclosure.

[0274] In some embodiments, the amount of microorganism or agricultural composition used to treat the plant elements will vary depending on the type of plant element and the type of active ingredient, but the treatment involves contacting the plant element with an agriculturally effective amount of a composition of the present invention.

[0275] As discussed above, an effective amount refers to that amount of a composition of the invention sufficient to affect beneficial or desired results. An effective amount can be administered in one or more administrations.

[0276] In some embodiments, in addition to the coating layer, the plant elements may be treated with one or more of the following ingredients: fungicides and other pesticides, including herbicides, herbicide antidotes, fertilizers, and / or biocontrol agents. These ingredients may be added as a separate layer or may be added to the coating layer.

[0277] In some embodiments, the plant element coating agent of the present disclosure can be applied to the plant elements using various techniques and machines, such as fluidized bed technology, roller milling, rotary electrostatic plant element processors, and drum coaters. Other methods, such as spouted beds, can also be useful. The seed plant elements can be pre-sized before coating. After coating, the plant elements are typically dried and then sent to a sizing machine for sizing. Such techniques are known in the art.

[0278] In some embodiments, the microbially treated plant elements may be enveloped in an overcoating film to protect the coating. Such overcoatings are known in the art and may be applied using fluidized bed and drum film coating techniques.

[0279] In another embodiment of the present disclosure, a composition according to the present disclosure can be introduced into plant elements using solid matrix priming. For example, a certain amount of the composition of the present disclosure can be mixed with a solid matrix material, and then the plant elements can be contacted with the solid matrix material for a period of time to allow the composition to be introduced into the plant elements. The plant elements can then be separated from the solid matrix material and stored or used as desired, or the mixture of the solid matrix material and plant elements can be stored or planted as is. Solid matrix materials 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 composition of the present invention over a period of time and releasing the composition into or onto the plant elements. It is useful to ensure that the composition of the present disclosure and the solid matrix material are compatible with each other. For example, the solid matrix material should be selected so that it can release the composition at a reasonable rate, for example, over minutes, hours, or days.

[0280] In some embodiments, the present disclosure teaches that individual microorganisms, or microbial consortia, or microbial communities developed according to the disclosed methods can be combined with any plant biostimulant.

[0281] 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.

[0282] In some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits an additive effect on a desired phenotypic trait in a plant when combined with an active chemical, while in other embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits a synergistic effect on a desired phenotypic trait in a plant when combined with an active chemical.

[0283] In some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits an additive effect on a desired phenotypic trait in a plant when combined with a fertilizer, while in other embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits a synergistic effect on a desired phenotypic trait in a plant when combined with a fertilizer.

[0284] In some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure is combined with a plant growth regulator to exhibit an additive effect on a phenotypic trait of interest in the plant. In some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure is combined with a plant growth regulator to exhibit a synergistic effect. In some aspects, a synergistic effect is observed for one or more phenotypic traits of interest when Ascend® and a microorganism of the present disclosure are combined.

[0285] In some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits an additive effect on a desired phenotypic trait in a plant when combined with a biostimulant, hi some embodiments, a microorganism or microbial consortium identified according to the methods of the present disclosure exhibits a synergistic effect when combined with a biostimulant.

[0286] The synergistic effect obtained by the methods taught 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, which is incorporated herein by reference in its entirety. Thus, by "synergistic" is intended an ingredient whose presence increases the desired effect beyond the amount added.

[0287] The isolated microorganisms and consortia of the present disclosure can synergistically enhance the efficacy of agriculturally active compounds and can also synergistically enhance the efficacy of agriculturally adjunct compounds.

[0288] In other embodiments, a synergistic effect is observed when a microorganism or microbial consortium identified according to the methods of the present disclosure is combined with a fertilizer.

[0289] Furthermore, in certain embodiments, the present disclosure utilizes synergistic interactions to define microbial consortia, i.e., in certain aspects, the present disclosure mixes certain isolated microbial species that act synergistically together into consortia that confer beneficial traits to plants or that correlate with increased beneficial plant traits.

[0290] In order to improve the activity of known active agricultural compounds, agricultural compositions developed according to the present disclosure can be formulated with certain adjuvants. This has the advantage that the amount of active ingredient in the formulation can be reduced while maintaining the efficacy of the active compound, thereby keeping costs as low as possible and complying with any official regulations. In individual cases, if treatment with a specific active ingredient without the addition of a certain adjuvant is not successful, adding the specific adjuvant together with the microbial isolates and consortia disclosed herein can actually successfully treat plants, thereby broadening the spectrum of action of the active compound. Also, in individual cases, a suitable formulation can enhance the performance of the active compound when environmental conditions are not favorable.

[0291] Such adjuvants that can be used in agricultural compositions can be adjuvants. Adjuvants often take the form of surface-active compounds or salt-like compounds. Depending on their mechanism of action, adjuvants can be broadly classified as modifiers, activators, fertilizers, pH buffers, etc. Modifiers affect the wetting, adhesion, and spreading properties of the formulation. Activators break down the waxy cuticle of plants, improving both short-term (over minutes) and long-term (over hours) penetration of the active ingredient into the cuticle. Fertilizers such as ammonium sulfate, ammonium nitrate, or urea can improve the absorption and solubility of the active ingredient and reduce its antagonistic behavior. pH buffers are conventionally used to achieve an optimal pH in the formulation.

[0292] In some embodiments, the plant element is a plant reproductive element (e.g., a seed, tuber, bulb, and / or shoot). In some embodiments, the plant element is other than a plant reproductive element (e.g., a leaf, stem, and / or root). In some embodiments, a plurality of plant elements are associated with a microorganism described herein.

[0293] In some embodiments, the plant or plant element becomes associated with one or more microorganisms described herein through indirect methods, such as, but not limited to, treatment of the growth medium in which the plant or plant element is placed.

[0294] For further embodiments of the agricultural compositions of the present disclosure, see "Chemistry and Technology of Agrochemical Formulations," edited by DA Knowles, 1998, copyright Kluwer Academic Publishers, Inc., which is incorporated herein by reference.

[0314] While the present invention has been particularly shown and described with reference to preferred embodiments and various alternative embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Various modifications, alterations, substitutions, and improvements of the present disclosure that will readily occur to those skilled in the art, including certain alterations, alterations, substitutions, and improvements, are also part of this disclosure. For example, the following specific examples may illustrate the methods and embodiments described herein using specific plants, but the principles of these examples may be applied to any plant. Therefore, it will be understood that the scope of the present invention is encompassed not only by the specific examples exemplified below, but also by the embodiments listed herein.

[0315] All cited patents and publications referenced in this application are herein incorporated by reference in their entirety for all purposes to the same extent as if each was individually and specifically incorporated by reference. [Example]

[0316] The methods and compositions presented herein improve one or more characteristics of plants, e.g., nitrogen fixation in agricultural crops, based on utilizing the disclosed isolated microorganisms, consortia, communities, and / or compositions comprising and / or produced by the microorganisms or consortia or communities.

[0317] The abbreviation "uL" means "microliter" and "ug" means "microgram."

[0318] An exemplary protocol is detailed herein, however, it should be understood that alternative methods and / or variations may be employed. Example 1: Microbial Cultivation, Sequencing, and Target Selection

[0319] The Paenibacillus strains defined in Table 1 were grown in culture medium to obtain sufficient cell growth.

[0320] Subsamples of each of these strains were then aseptically transferred to nitrogen-free growth medium and incubated under microaerobic conditions for 72 hours.

[0321] Isolates of interest were grown to mid-logarithmic phase in R2A medium. DNA was extracted with the Qiagen Powersoil DNA Extraction Kit, and sequencing libraries were constructed with the iGenomix RipTide kit according to the manufacturer's instructions. Sequencing was performed on an Illumina HiSeq using PE150. Raw Illumina reads were trimmed to Q15 with Trimmomatic v38 (Bolger AM, Lohse M, and Usadel B. (2014). Trimmomatic: A flexible trimmer for Illumina Sequence Data. Bioinformatics, btu170) and assembled with SPAdes (Prjibelski A, Antipov D, Meleshko D, Lapidus A, and Korobeynikov A. (2020). Using the UniCycler de novo assembler. Curr. Protocol. Bioinform. 70, e102) using default parameters. Assembled contigs were analyzed for purity with a <5% contamination cutoff using BinSantity 0.5.4 (Graham ED, Heidelberg JF, and Tully BJ. (2017) BinSanity: unsupervised clustering of environmental microbial assemblies using coverage and affinity propagation. PeerJ 5:e3035). The largest bin was extracted and annotated with Prokka 1.14 (Seemann T. (2014) Prokka: rapid prokaryotic genome annotation. Bioinformatics 30(14):2068-9). 16S rDNA sequences were identified using Prokka 1.8, and sequences were extracted directly from the .ffn files.Taxonomy was assigned either by the top hits of BLAST matches of 16S rRNA DNA sequences and / or by GTDB-tk using default parameters on the April 2021 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).

[0322] A selection of Paenibacillus strains was characterized as subgroup I or subgroup II according to the method of Xie et al. (2014) (Comparative Genomic Analysis of N2-Fixing and Non-N2-Fixing Paenibacillus spp.: Organization, Evolution, and Expression of the Nitrogen Fixation Genes. 10(3)). The nif gene cluster, consisting of nifB, nifH, nifD, nifK, nifE, nifN, nifX, hesA, and nifV, is highly conserved among the 15 N2-fixing Paenibacillus strains, but there is some variation in the DNA sequence of the nif cluster, which can be divided into two subgroups: subgroup I and subgroup II. The nine genes of the nif gene cluster, nifBHDKENXhesAnifV, are contiguous within subgroup I, while a 261- to 561-bp ORF with an unknown predicted product is located between nifX and hesA within subgroup II. The Paenibacillus species P. polymyxa and P. tritici are examples of subgroup I. The 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.

[0323] Paenibacillus strains (Wang et al.) containing bioinformatically determined nitrogen fixation-related genes are detailed in Table 2. Not all Paenibacillus microorganisms contained the nitrogen fixation cluster genes required for nitrogen fixation capability (e.g., strain 4330 Paenibacillus agarexedens (provided by 16S as SEQ ID NO: 257)). Furthermore, not all Paenibacillus polymyxa microorganisms contained the nitrogen fixation cluster genes required for nitrogen fixation capability (e.g., strain 7228 (provided by 16S as SEQ ID NO: 258)).

[0324] In some cases, the annotator algorithm identified different variants of the same gene based on disclosures in the technical literature, for example, hesA has two different variants, hesA1 and hesA2.

[0325] As noted with an asterisk in Table 2 , assembly errors were encountered in two strains in the GlnR region.

[0326] Some strains contained more than one nif cluster in their genomes. Strain 17897 contained at least two nif clusters. Strain 17912 contained at least two nif clusters. Strain 17947 contained at least two nif clusters. Strain 17948 contained at least two nif clusters. Strain 77901 contained at least two nif clusters. Strain 102018 contained at least two nif clusters. Strain 102020 contained at least two nif clusters. Strain 102088 contained at least two nif clusters. Strain 17911 contained at least two nif clusters. Strain 103408 contained at least two nif clusters. Strain 104107 contained at least two nif clusters.

[0327] Several strains contain both the canonical nif cluster and the anf genes, including strains 17911, 103408, 104107, 104182, and 106252. [Table 2-1] [Table 2-2] [Table 2-3] [Table 2-4] [Table 2-5] [Table 2-6] [Table 2-7]

[0328] Example 2: Identification and storage of microorganisms Sequencing preparation and long-term storage for microbial identification was performed by the following method.

[0329] Day 1: Using a 10 uL sterile tip, transfer the colony from the plate to a flask containing the appropriate liquid growth medium. Place the isolate on a shaker at room temperature and incubate for 2 days.

[0330] Day 3: The tubes may become cloudy after 2 days on a shaker. All samples are analyzed by PCR. Vortex each tube and collect 50 μL of sample from each vortexed tube and dispense into a 96-well plate. Using a multichannel pipette, dispense 15 μL of the 50 μL sample into a new 96-well plate. The 96-well plate containing 35 μL of each sample will be used for phenotypic analysis, and the 96-well plate containing 15 μL of each sample will be used for PCR analysis. The 27F / 1492R primers generally are used for 16S PCR analysis because they yield better results than PB36 / 38. Appropriate negative controls should be included on the plate and analyzed by PCR. The plate is analyzed by PCR using an Eppendorf thermocycler. Once PCR is complete, run the gel using standard gel electrophoresis techniques. This is important because most isolates ideally grow well in their long-term storage location by day 3. PCR and gel electrophoresis analysis are used to confirm that the isolate contains bacteria and not other microorganisms. For isolates that do not pass PCR or have a clear broth, vortex the tube and streak it onto a Petri dish using a loop. After a few days, check to see if anything has grown or if the tube is contaminated. For isolates that pass PCR, dispense 600 μL of 50% glycerol into a 2 ml screw-cap tube and add 1200 μL of bacterial culture, so that the broth is stocked in 20% glycerol. Store the glycerol stock at -80°C and record a gel image of the PCR sample. Day 4:

[0331] Check the Petri dish for streaky isolates that failed PCR for growth. (During this time, the 2 ml broth tube will remain on the shaker.) If there is growth on the dish and the colonies appear to be successfully isolated, dispense 600 μL of the broth-glycerol mixture into a small tube and place both tubes in their respective -80 boxes. Isolates may fail the PCR check for 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 excessive EPS and therefore requires dilution before PCR setup; or the isolate grows slowly. Continue checking the dish over the next few days to ensure that only a single bacterial species has been isolated. If contamination is observed, prepare a new isolate. The viability of the prepared glycerol stock should be verified.

[0332] Example 3: Microbial formulation Microorganisms identified according to the preceding examples can be formulated with additional components for application via methods such as, but not limited to, seed treatment, root drench, root wash, seedling dip, foliar spray, soil inoculation, furrow application, lateral fertilization, soil pre-treatment, wound inoculation, drip tape irrigation, pollinator-mediated vector transfer, injection, osmotic priming, hydroponics, aquaponics, and aeroponics. Formulations containing the microorganisms are prepared for agricultural use as liquid, solid, or gas formulations. Application to plants can be accomplished, for example, as a powder for surface deposition on plant leaves, as a spray on the whole plant or selected plant elements, as part of a drip onto the soil or roots, or as a coating on plant elements prior to planting. Such examples are intended to be illustrative and not limiting of the scope of the present invention.

[0333] The media components for an exemplary microbial preparation are shown below: Add all contents along with 50% of the final volume of water required and stir the solution at elevated temperature until dissolved. After all contents are dissolved, use sterile RO water to bring the solution to the final desired volume. Field test preparations are typically performed using quadruplicate formulations. [Table 3] [Table 4] [Table 5] [Table 6]

[0334] The procedure for mixing the TIX formulation is as follows: Weigh all dry ingredients into a 50 mL tube. Vortex the ingredients well to ensure the xanthan gum is "separated" from the other carbon sources. Add approximately half of the total sterile RO water to the mixture and vortex. Use the long end of an L-shaped spreader to break up clumps as much as possible. Heat some sterile RO water in the microwave to hot water bath temperature (45-50°C). Add the remaining sterile RO water to the mixture and vortex. Repeat step 4 and vortex as necessary until a clear solution without lumps is obtained. Sediment any air bubbles created during the mixing process by using the centrifuge on "high speed spin" for 5-10 seconds. Remember to counterbalance the formulation (TIX) tube. Allow the formulation to cool to room temperature. 1. Mix in the microbial consortium. Vortex to ensure homogeneity. Ideally, add microorganisms at a concentration of 10^9 CFU / ml to the formulation.

[0335] For testing in field trials, the formulation is applied to plants or plant elements.

[0336] Example 4: Application of microorganisms to plant elements and their cultivation Microbial compositions (comprising one or more isolated microorganisms, whether single strain, consortium, community, combination, or any combination of the foregoing) are prepared according to the previous examples. The microbial compositions include one or more microorganisms, optionally in combination with one or more additional microorganisms disclosed herein.

[0337] Microbial compositions for application In some methods, the microbial composition is dried and applied directly to the plant elements.

[0338] In some methods, the microbial composition is suspended in a liquid formulation for application to the plant elements.

[0339] In some methods, the microbial composition is combined with another composition, such as, but not limited to, a carrier, a wetting agent, a stabilizer, or a salt. In some methods, the other composition comprises a molecule that induces additional agriculturally beneficial effects in the plant to which the microbial composition is applied. Examples of other compositions include, but are not limited to, herbicides, fungicides, bactericides, pesticides, insecticides, nematicides, and biostimulants.

[0340] Applicable Type The microbial composition is applied to the plant elements at a time during development appropriate for the desired result, for example, in a pre-plant soil drench / in-furrow formulation, as a seed or other reproductive element treatment, as a post-plant reproductive element application, as a post-plant in-furrow, drip, or drench application, as a direct application to the plant elements (e.g., roots, leaves, stems), or as an application to harvested plant elements (e.g., fruit or grain). Combinations of application types are also tested.

[0341] How to apply The microbial composition is applied (inoculated) to the plant or plant element or plant product (before planting, after planting, before harvest, or after harvest). This can be accomplished, for example, by applying the agricultural composition to a hopper, spreader, or tank that contains the microbial composition and is configured to spread it widely.

[0342] A seed coating of the microbial composition is applied to one or more seeds of a crop plant. Once the isolated microorganism has been applied as a seed coating, the seeds are planted and grown according to established practices for that crop.

[0343] Alternatively, the microbial composition is applied to the soil for the benefit of plants present in the soil. Methods of soil application include in-furrow treatment, drench, and drip application.

[0344] Alternatively, the microbial composition is applied to the surface of the plant or plant part after emergence.

[0345] Alternatively, the microbial composition is applied to material obtained from the plant after harvest.

[0346] Control plots of plants to which the isolated microorganisms were not applied are also planted. Plants associated with the microbial composition show improvement in the desired trait.

[0347] The application method may be carried out according to any protocol known in the art.

[0348] The plant elements, plants, or growth medium (eg, soil) can be further inoculated with a disease or pest depending on the purpose of the test.

[0349] An exemplary, non-limiting protocol for irrigating tomato plants is given below. 1. Ten days after planting, carefully separate the plants into six rows for each treatment. The plants are delicate and the leaves can tear easily. Ensure that the plants are as uniform as possible in size and overall appearance (the purpose of thinning is to maintain a homogenous plant population). If there are not enough plants per row, transplant them. See Step 3 for transplanting guidelines. 2. Begin thinning the pots down to one plant per pot. Remove any smaller plants, those that are unhealthy, or deformed in any way. If there are two or more healthy plants per pot, the excess can be transplanted into another pot. Use the remaining soil prepared from the initial planting or from pots where the seeds did not germinate. 3. To transplant: If some pots did not germinate, they can be filled with plants from another container. To do this, simply scoop out the excess plants with a scoop (trying to scoop out as much of the root mass as possible without disturbing the other plants) and place them in the hole made in the empty pot. Firm the soil around the plants with slight finger pressure. 4. Arrange the pots into 6 pot lines (one pot line per treatment) and take 4 RL98 trays. Once finished, look at all the treatments and allow for several pot rotations to ensure some treatments are free of all large plants and other treatments have all large plants. 5. Change gloves if necessary. Label each pot with the Avery labels you prepared in advance. Treatments should be labeled in columns of six replicates, i.e., 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, etc. This will make it easier to find all the replicates for each treatment. 6. Two weeks after planting (approximately four days after thinning and labeling), receive treatment from the microbiology team. Arrange the prepared plant trays on the table. Collect Combi-Tip, Repeater, and RO water. (Note: Plants should be lightly watered on the day of treatment) 7. Mix the microbial solution by inverting the tube / container (microbial treatment) 2-3 times or gently shaking. Set the Combitip to dispense 2 ml. Collect the treatment fluid in the Combitip and dispense the first step back into the tube. Ensure that the treatment corresponds to the row of plants being treated. Once confirmed, gently dispense 2 ml of treatment onto the topsoil of each pot, close to the stem, but avoiding direct contact with the stem and leaves. 8. Discard the Combitip and repeat step 6 for all treatments. For the inoculated controls (IC or InoCon) and untreated controls (UTC), apply RO water instead of treatment. Once all treatments have been applied, the plants are placed back into the growth chamber for (optional inoculation), growth and evaluation.

[0350] Visualization of microorganisms associated with plant elements Individual microorganisms can be tagged with fluorescent proteins according to methods known in the art. Microscopic image analysis demonstrated that the microorganisms disclosed herein can be found associated with various plant tissues.

[0351] Example 5: In vitro testing Strains are evaluated for root colonization, acetylene reduction activity, biofilm formation, turbidity (OD at 600 nm), oxygen tolerance, and gene expression. Strain IDs are provided as <strain number>. Protocols were performed using methods known in the art unless otherwise specified. Data are shown in Table 4.

[0352] ARA by GC-FID for Gram-positive strains All equipment and materials were ensured to be sterilized. The closure containers were wrapped in foil prior to autoclaving so that they could be unwrapped in the anaerobic chamber pass box and enter the anaerobic chamber sterile. The vial openings were sealed with foil prior to sterilization. A loose "seal" is required to allow gas exchange within the pass box. The protocol followed was as follows: 1. Streak the isolate from -80°C and incubate at 30°C or 25°C until colonies are observed. 2. Spread one plate per isolate and incubate at 25°C or 30°C until a bacterial lawn is observed. 3. Harvest plates and balance to approximately 0.3 OD600 for each isolate to normalize the inoculum. 4. Prepare the anaerobic chamber by cleaning the surface and passing a sealing device, ensuring the container allows gas exchange. Add 30 mL of NF11 to 5.70 mL vials - 3 times per isolate. 6. Add 150uL of inoculum / vial balanced to an OD600 of 0.3 using sterile water. 7. Pass the vials through the anaerobic chamber and seal under anaerobic conditions, and include an empty vial (with foil "cap") for adding an anaerobic indicator for QC purposes. 8. Place the vial at 30°C and 200 rpm for 5 hours. After 9.5 h, working in a fume hood, remove 10% (4 mL) from the headspace of each vial and replace it with an equal volume of acetylene gas. 10. Incubate at 30°C and 200 rpm for 48 hours. At 11.48 hours, a 1 mL headspace sample is taken and placed in a GC collection tube. 12. Run the sample on the GC using instrument method "Split 4" for ethylene analysis, which measures the acetylene and ethylene peaks. 13. Quantify the amount of gas by peak area. 14. Obtain an OD600 measurement of 200 ul of culture and TVC of the culture. 15. Analyze ethylene gas as the percentage conversion of acetylene to ethylene. This provides an estimate of total conversion.

[0353] The volume of gas (ethylene) produced can be quantified either by using calibration points in the Chromeleon or by calculating from the peak area %. In this case, the acetylene + ethylene peak area % should be 100%. From the known amount of acetylene added, the ethylene produced can be determined in mL. 1M gas is 24 dm3 or 24,000 ml. Therefore, 1 mM gas is 24 ml.

[0354] To calculate how many mM ethylene were produced, divide the amount by 24: mM ET = ml / 24.

[0355] To calculate the RATE: mM / hour / CFU, the mM must be calculated as above.

[0356] Rate = Total ethylene mM / (Time (hr) x Total CFU)

[0357] ARA with oxygen tolerance test protocol Ensure all equipment and materials are sterilized. Sealed device containers are wrapped in foil before autoclaving so that they can be unwrapped in the anaerobic chamber pass box and enter the anaerobic chamber sterile. Seal vial openings with foil before sterilization. A loose "seal" is required to allow gas exchange within the pass box. 1. Streak the isolate from -80°C and incubate at 30°C or 25°C until colonies are observed. 2. Spread one plate per isolate and incubate at 25°C or 30°C until a bacterial lawn is observed. 3. Harvest plates and balance to approximately 0.3 OD600 for each isolate to normalize the inoculum. 4. Prepare the anaerobic chamber by cleaning the surface and passing a sealing device, ensuring the container allows gas exchange. 5. After clarification, load NF11 medium into the anaerobic chamber. Add 20 g / L agar to the NF11 and place on a hot plate. Boil briefly to dissolve the agar. After the agar is dissolved, pour 30 mL of warmed agar into the 70 mL container, pouring it over its side and tilting it to maximize the surface area. 6. Add 150uL of inoculum / vial balanced to an OD600 of 0.3 using sterile water. Try to maximize the surface area exposed to the inoculum. 7. Pass the vials through the anaerobic chamber and seal under anaerobic conditions, and include an empty vial (with foil "cap") for adding an anaerobic indicator for QC purposes. 8. To adjust the oxygen level, after sealing the vial, remove a thin needle syringe and remove some of the anaerobic air from the vial, replacing it with 100% pure medical-grade oxygen. 9. This assay has been run under various oxygen conditions, ranging from 0% oxygen to 22% oxygen, and can be increased to much higher oxygen conditions by manually adding oxygen. For example, to achieve 5% oxygen, 2.2 mL of anaerobic gas is manually removed and 2 mL of 100% pure oxygen is added back into the assay. 10. Place the vial in a 30°C incubator for 5 hours. After 12.5 hours, working in a fume hood, remove 10% (4 mL) of the headspace from each vial and replace it with an equal volume of acetylene gas. Incubate at 30 °C for 48 hours. At 13.48 hours, a 1 mL headspace sample is taken and placed in a GC collection tube. 14. Run the sample on the GC using instrument method "Split 4" for ethylene analysis, which measures the acetylene peak and ethylene peak. 15. Quantify the amount of gas by peak area. 16. Analyze ethylene gas as the percentage conversion of acetylene to ethylene. This provides an estimate of total conversion.

[0358] The volume of gas (ethylene) produced can be quantified either by using calibration points in the Chromeleon or by calculating from the peak area %. In this case, the acetylene + ethylene peak area % should be 100%. From the known amount of acetylene added, the ethylene produced can be determined in mL. 1 M gas is 24 dm3 or 24,000 ml. Therefore, 1 mM gas is 24 ml. To calculate how many mM ethylene was produced, divide the volume by 24: mM ET = ml / 24.

[0359] To calculate the RATE: mM / hour / CFU, the mM must be calculated as above.

[0360] Rate = Total ethylene mM / (Time (hr) x Total CFU)

[0361] Root colonization Bacterial strains are prepared with a GFP gene integrated into their genome using techniques known in the art. Seeds are treated with the strain, and the inoculated seeds are dropped into phytagel tubes using sterile techniques. The tubes are placed in a suitable growth chamber, covered, and allowed to germinate for 5 days. Root tissue is separated from the seeds and shoots using EtOH and flame-sterilized tweezers and scalpels. All root tissues are cut at the same focal plane and pressed at the same level into 0.8% water agar in a square plate for imaging. The same is done for shoot tissue. Plant tissues are imaged for bacterial colonization using a fluorescent microscope.

[0362] Biofilm assay protocol This protocol is based on the publication "Effects of an EPS Biosynthesis Gene Cluster of Paenibacillus polymyxa WLY78 on Biofilm Formation and Nitrogen Fixation under Aerobic Conditions" (Chen 2021). Materials: Sterile 3 mL glass tubes, "biofilm broth (BFB)" medium, 0.1% crystal violet (water), and 40% acetic acid. Seven days provided the best overall biofilm results. Prepare using sterile technique.

[0363] The BFB recipe includes 5g / L KH2PO4, 5g / L K2HPO4, 0.86g / L monosodium glutamate, 0.1g / L yeast extract, and 1g / L NH4Cl (pH 7). Filter-sterilized after autoclaving: 36g / L glucose, 0.03g / L MgSO4.7H2O, 0.02g / L CaCl2.2H2O, 22.7mg / L MnSO4-H2O, 0.0785mg / L ZnSO4, 0.001mg / L CuSO4, 0.004mg / L Na2MoO4, and 5.4mg / L FeSO4.

[0364] The method steps were as follows: 1. Streak the isolate from -80°C. 2. Prepare spread plates for each isolate. Autoclave 3.3 mL glass tubes (3 per isolate) in a tube rack and use foil as a cover. 4. Collect the diffusion plate and balance to an OD600 of approximately 0.3. 5. Fill each tube with 1 mL of BFB. 6. Inoculate 10 uL / tube of spread plate harvest. 7. Place the foil cover back on the tube and incubate undisturbed at 30°C for 7 days. After 8.7 days, first remove the culture from the tube using a long (1250 uL) pipette tip and collect the culture into a 2 mL snap-cap tube. 9. Add water to the culture to reach a final volume of 1 mL. Take an OD600 reading. 10. Rinse the glass tube using RO water, filling it approximately halfway, holding the tube, sealing the top, and shaking to remove excess cellular material. Rinse several times. 11. Use a long pipette tip to remove excess water. Add 12.1 mL / tube of 0.1% crystal violet solution and incubate at room temperature for 10 minutes. 13. Remove the crystal violet solution by pipetting into a waste container (e.g., a 50 mL Falcon tube) and discard in an incineration waste bin. 14. Rinse the glass tube until the water runs clear. 15. Allow the glass tube to dry (usually overnight). Add 16.1 mL of 40% acetic acid solution to dissolve the stained biofilm ring. 17. Take an OD570 reading. 18. Normalize OD570 to OD600 (if applicable). [Table 7-1] [Table 7-2] [Table 7-3] [Table 7-4] [Table 7-5] [Table 7-6] [Table 7-7] [Table 7-8] [Table 7-9] [Table 7-10] [Table 7-11] [Table 7-12] [Table 7-13]

[0365] Example 6: In plant testing The above mentioned microorganisms are tested on different types of monocotyledonous crop plants, C3 monocotyledonous (wheat) and C4 monocotyledonous (corn), as well as dicotyledonous plants such as soybean, tomato, cotton, lettuce.

[0366] Plants are associated with the above-mentioned microorganisms and tested in greenhouse and large-scale field trials according to standard protocols. Association can be achieved by any one or more of seed treatment, foliar treatment, furrow application, irrigation, and lateral application.

[0367] Multiple replicates of plants are treated with the microorganisms described herein and grown. Data collected includes biomass, leaf area, plant height, root area, shoot nitrogen, greenness, NDVI (which captures how much near-infrared light is reflected compared to visible red light; a measure of plant health based on how the plant reflects light at a certain frequency), NPCI (Normalized Pigment Chlorophyll Ratio Index), PSRI (Plant Senescence Reflectance Index), and CCI (Chlorophyll Content Index), and yield, compared with untreated controls.

[0368] Taken together, these methods provide evidence that plants can benefit from improved nitrogen fixation capacity through association with the Paenibacillus strains described herein.
