[0058] Currently available commercial citrus plants and solanaccous crops lack tolerance or resistance to Huanglongbing (HLB) and Zebra Chip (ZC) disease. Due to the rapid spread of bacteria of genus Ca. Liberibacter, new methods to prevent infections are required. One of the ways Candidatus Liberibacter species may elicit the physiological symptoms of HLB and other diseases, such as Zebra Chip, is by secretion of proteins into the plant. Candidatus Liberibacter species use the general secretion pathway (Sec-pathway) to deliver effector proteins (Sec Dependent Effectors, SDEs) into plant cells. The SDEs interact with host susceptibility proteins (S-proteins) and alter their function or abundance. Therefore, genetically modifying the genes encoding S-proteins in citrus and solanaccous plants is a viable alternative to conventional plant breeding for producing varieties that are resistant to Ca. Liberibacter infection and / or its associated diseases. It is a relatively rapid process, and some techniques allow for targeted modification of genetic loci without significant off-target effects.
[0059] In some embodiments, genetic modifications to at least two S-proteins are employed in order to generate citrus plants and solanaccous plants that are resistant to HLB and ZC, respectively. In some embodiments, the modified plants are less likely to suffer from physiological symptoms of HLB or ZC than native plants without modification. In specific embodiments, the citrus plants and solanaccous plants are tolerant to Ca. Liberibacter. Therefore, in some embodiments, the modified plants are less likely to develop undesirable physiological symptoms from Ca. Liberibacter infection and in some embodiments, the modified plants are less likely to be infected by Ca. Liberibacter than native plants or will have a lower copy number after infection. The use of modified S-proteins as disclosed herein to generate disease resistant citrus and solanaccous plants provides a significant improvement over the art due to the prior lack of agronomically acceptable plants with resistance to Ca. Liberibacter infection and to HLB and / or ZC disease. In some embodiments, additional modifications may be made to other genes that render resistance to Ca. Liberibacter infection and to HLB and / or ZC disease.
[0060] Also provided herein are citrus plants and solanaccous plants with one or more modifications to S-proteins that render the citrus plant tolerant to pathogenic Ca. Liberibacter species. In some embodiments, citrus plants with modifications to two or more S-proteins are provided, where the modifications provide the citrus plants with resistance to HLB infection. In some embodiments, solanaceous plants with modifications to two or more S-proteins are provided,where the modifications provide resistance to ZC disease. In some embodiments, the plants are non-transgcnic. In some embodiments, the plants arc transgenic. In specific embodiments, Valencia orange plants that are resistant to HLB are provided. In some embodiments, the Valencia orange plants comprise modifications to two or more S-proteins, such as ACD2 and List. In some embodiments, Hamlin plants comprising modifications to two or more S-proteins, such as ACD2, CP and Llsl are provided. In some embodiments, Carrizo plants comprising modifications to two or more S-proteins, such as ACD2, CP and Llsl are provided. In some embodiments, a citrus plant comprising a modification to Putative F-box protein (PP2-B 12) is provided. In some embodiments, a citrus plant comprising a modification to PP2-B12 in addition to a modification to at least one endogenous S-protein gene or regulatory element thereof, selected from a group consisting of Accelerated Cell Death 2 (ACD2), Cysteine Protease (CP), Lethal Leaf Spot 1 (Llsl) and Accelerated Cell Death Like 1 is provided. As will be understood to those of skill in the art, once a genetic modification conferring resistance to HLB or ZC is generated, this modification can readily be introduced into other cultivars by, for example, crossing.
[0061] In some embodiments one or more additional modifications may be included in order to provide a desired physiological characteristic.Definitions
[0062] The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
[0063] Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood when read in light of the instant disclosure by one of ordinary skill in the art to which the present disclosure belongs. For purposes of the present disclosure, the following terms are explained below.
[0064] As used herein, “a” or “an” may mean one or more than one.
[0065] As used herein, the term “about” or “approximately” has its usual meaning as understood by those skilled in the art and thus indicates that a value includes the inherent variationof error for the method being employed to determine a value, or the variation that exists among multiple determinations.
[0066] Throughout this specification, unless the context requires otherwise, the words “comprise,” “comprises,” and “comprising” will be understood to imply the inclusion of a stated step or element or group of steps or elements but not the exclusion of any other step or element or group of steps or elements. By “consisting of” is meant including, and limited to, whatever follows the phrase “consisting of.” Thus, the phrase “consisting of’ indicates that the listed elements are required or mandatory, and that no other elements may be present. By “consisting essentially of’ is meant including any elements listed after the phrase and limited to other elements that do not interfere with or contribute to the activity or action specified in the disclosure for the listed elements. Thus, the phrase “consisting essentially of” indicates that the listed elements are required or mandatory, but that other elements are optional and may or may not be present depending upon whether or not they materially affect the activity or action of the listed elements.
[0067] As used herein, “nucleic acid”, “nucleic acid molecule”, or “nucleotide” refers to polynucleotides or oligonucleotides such as deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), oligonucleotides, fragments generated by the polymerase chain reaction (PCR), and fragments generated by any of ligation, scission, endonuclease action, exonuclease action, and by synthetic generation. Nucleic acid molecules can be composed of monomers that are naturally- occurring nucleotides (such as DNA and RNA), or analogs of naturally-occurring nucleotides (e.g., enantiomeric forms of naturally-occurring nucleotides), or a combination of both. Modified nucleotides can have alterations in sugar moieties and / or in pyrimidine or purine base moieties. Nucleic acids can be either single stranded or double stranded.
[0068] The term “homology” refers to nucleic acid sequences that have a sequence identity in at least about 50% of the nucleotide bases, usually at least about 60%, more usually at least about 80%, preferably at least about 90%, and more preferably at least about 95-98% of the nucleotide bases. When referring to polypeptides, the term “homology” indicates that the polypeptide or protein in question exhibits at least about 30% identity with an entire naturally occurring protein or a portion thereof, usually at least about 70% identity, and preferably at least about 95% identity.
[0069] “Percentage of sequence identity” can be determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotidesequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (c.g., a polypeptide of the constructs provided herein), which docs not comprise additions or deletions, for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity.
[0070] The terms “identical” or percent “identity,” in the context of two or more nucleic acids or polypeptide sequences, refer to two or more sequences or subsequences that are the same sequences. Two sequences are “substantially identical” if two sequences have a specified percentage of amino acid residues or nucleotides that are the same (for example, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% sequence identity over a specified region, or, when not specified, over the entire sequence of a reference sequence), when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual inspection. Some embodiments provided herein provide polypeptides or polynucleotides that are substantially identical to the polypeptides or polynucleotides, respectively, exemplified herein. Optionally, the identity exists over a region that is at least about 15, 25 or 50 nucleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length, or over the full length of the reference sequence. With respect to amino acid sequences, identity or substantial identity can exist over a region that is at least 5, 10, 15 or 20 amino acids in length, optionally at least about 25, 30, 35, 40, 50, 75 or 100 amino acids in length, optionally at least about 150, 200 or 250 amino acids in length, or over the full length of the reference sequence. With respect to shorter amino acid sequences, e.g., amino acid sequences of 20 or fewer amino acids, in some embodiments, substantial identity exists when one or two amino acid residues are conservatively substituted, according to the conservative substitutions defined herein.
[0071] For sequence comparison, typically one sequence acts as a reference sequence, to which test sequences are compared. When using a sequence comparison algorithm, test and reference sequences are entered into a computer, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters arc designated. Default program parameters can be used, or embodiment parameters can be designated. The sequence comparisonalgorithm then calculates the percent sequence identities for the test sequences relative to the reference sequence, based on the program parameters.
[0072] The term “gene” as used herein have their plain and ordinary meaning as understood in light of the specification, and generally refers to a portion of a nucleic acid that encodes a protein or functional RNA; however, the term may optionally encompass regulatory sequences. It will be appreciated by those of ordinary skill in the art that the term “gene” may include gene regulatory sequences (e.g., promoters, enhancers, etc.) and / or intron sequences. It will further be appreciated that definitions of gene include references to nucleic acids that do not encode proteins but rather encode functional RNA molecules such as tRNAs and miRNAs. In some cases, the gene includes regulatory sequences involved in transcription, or message production or composition. In other embodiments, the gene comprises transcribed sequences that encode for a protein, polypeptide or peptide. In keeping with the terminology described herein, an “isolated gene” may comprise transcribed nucleic acid(s), regulatory sequences, coding sequences, or the like, isolated substantially away from other such sequences, such as other naturally occurring genes, regulatory sequences, polypeptide or peptide encoding sequences, etc. In this respect, the term “gene” is used for simplicity to refer to a nucleic acid comprising a nucleotide sequence that is transcribed, and the complement thereof. As will be understood by those in the art, this functional term “gene” includes both genomic sequences, RNA or cDNA sequences, or smaller engineered nucleic acid segments, including nucleic acid segments of a non-transcribed pail of a gene, including but not limited to the non-transcribed promoter or enhancer regions of a gene. Smaller engineered gene nucleic acid segments may express, or may be adapted to express using nucleic acid manipulation technology, proteins, polypeptides, domains, peptides, fusion proteins, mutants and / or such like.
[0073] As used herein, the term “wild-type” has its plain and ordinary meaning as understood in light of the specification, and generally refers to a gene, a gene locus, a polynucleotide sequence, a nucleotide sequence or a protein that does not comprise any edits or modifications. A “wild type” gene, gene locus, a polynucleotide, a nucleotide sequence or a protein means that the gene, gene locus, polynucleotide, nucleotide sequence or protein will be active at a level of activity found in nature and / or will comprise the nucleotide or amino acid sequence found in nature. Unless specified otherwise, a “genomic locus” or a “genomic loci” as used herein refers to a genomic locus or a genomic loci that does not comprise any edits or modifications.
[0074] An “expression vector” or a “vector,” as described herein, is a nucleic acid molecule encoding a gene that is expressed in a host-cell. Typically, an expression vector comprises a transcription promoter, a gene, and a transcription terminator. Gene expression is usually placed under the control of a promoter, and such a gene is said to be “operably linked to” the promoter. Similarly, a regulatory element and a core promoter are operably linked if the regulatory element modulates the activity of the core promoter.
[0075] As used herein, modifying a genome is carried out with techniques that employ targeted mutagenesis. These techniques include, but are not limited to, those that utilize endonucleases to generate single-strand and double-strand DNA breaks that activate DNA repair pathways. Genome editing techniques may also comprise systems that enable targeted editing at any genomic locus. These targeting systems include, but are not limited to, polypeptides, such as, Transcription Activator-Like Effectors (TALEs) and zinc fingers (ZFs), or nucleic acids, such as, Clustered Regularly Interspaced Short Palindromic Repeats / Cas (CRISPR / CAS) single guide RNAs or NgAgo (Argonaute) single strand DNAs. As used herein, “genome editing” and “genome-engineering” are interchangeable.
[0076] As used herein, genetic modification refers to a DNA sequence difference, epigenetic difference, or combination thereof between two genomes of the same species in which one genome is identified as the modified genome and the other is identified as the unmodified genome and the DNA sequence or epigenetic difference is the result of applying genome modifying techniques to the unmodified genome to yield the modified genome. A genetic modification, as used herein, encompasses any insertion, deletion, or substitution of a nucleotide sequence of any size and nucleotide content, any epigenetic modification to any number of nucleotides, or a combination thereof. A genetic modification, as used herein, may also encompass introduction of one or more exogenous coding nucleic acids that do not integrate into the unmodified genome, yet are capable of autonomous replication. In certain embodiments, a modification to an endogenous gene or regulatory element thereof may be a deletion, a substitution, or an insertion that reduces expression of the endogenous gene or the polypeptide for which it encodes. In some specific embodiments, the modification may be an indel, wherein the indel may cause a frameshift mutation, a missense mutation, a nonsense mutation, a neutral mutation, or a silent mutation. In specific embodiments, a modification to a regulatory element of an endogenous gene may alter or eliminate a function of the regulatory element. In furthercontemplated embodiments, the modification may comprise a nucleic acid sequence that provides exogenous control of endogenous gene, mRNA, or polypeptide expression levels. In specific embodiments, the modification may also disrupt a post-translational process of a polypeptide encoded by an endogenous gene. Post-translational processes in certain embodiments may be post- translational modifications, protein sorting, or proteasomal degradation.
[0077] As used herein, a genetically modified cell is a cell in which the endogenous genome has been genetically modified; a cell in which one or more exogenous, coding nucleic acids have been introduced that do not integrate into the genome, yet are capable of autonomous replication; or a combination thereof.
[0078] As used herein, a genetically modified plant is a plant comprising at least one genetically modified cell. A genetically modified plant may be regenerated from a genetically modified cell or plant part comprising genetically modified cells, and thus the genetic modification may be heritable and inherited by progeny thereof. The progeny thereof that inherit the genetic modification are also considered genetically modified plants. A genetically modified plant, as used herein, also refers to a plant in which at least one genetically modified cell is introduced to a plant or arises as a result of genetic modification techniques directly applied to the plant.
[0079] As used herein, a genetic modification technique is a technique that is known to those in the art that can modify the genome of a cell including, but not limited to, genome editing, site-specific genetic recombination, epigenetic modifications, and genetic transformation.
[0080] As used herein, a genetic transformation is a process of introducing a DNA sequence or construct (e.g., a vector or expression cassette) into a cell or protoplast in which that exogenous DNA is incorporated into a chromosome or is capable of autonomous replication.
[0081] As used herein, the term transgenic refers to a cell or a plant that expresses nucleic acids at an unnatural locus in the genome, i.e. homologous or, preferably, heterologous expression of the nucleic acids. Alternatively, as used herein, a non-transgenic plant or cell comprises modified nucleic acids expressed at their natural locus in the genome.
[0082] As used herein, a heterologous sequence is a sequence which is not normally present in a given host genome in the genetic context in which the sequence is currently found. In this respect, the sequence may be from another species, organism, plant, tree, or variety, or may be native to the host genome, but be rearranged with respect to other genetic sequences within the host sequence. For example, a regulatory sequence may be heterologous in that it is linked to adifferent coding sequence relative to the native regulatory sequence. In addition, a particular recombinant DNA molecule may be heterologous with respect to a cell or organism into which it is inserted when it would not naturally occur in that particular cell or organism.
[0083] As used herein, “regeneration” is the process of growing a plant from a plant cell (e.g., plant protoplast, callus, or explant).
[0084] As used herein, the term “plant” refers to citrus or solanaceous plant, or any other plant that can be infected by a Ca Liberibacter species.
[0085] As used herein, the term “plant part” refer to cells, tissues, organs, seeds, rootstock, scion, interstock and severed parts (e.g., roots, leaves, and flowers) that retain the distinguishing characteristics of the parent plant. “Seed” refers to any plant structure that is formed by continued differentiation of the ovule of the plant, following its normal maturation point at flower opening, irrespective of whether it is formed in the presence or absence of fertilization and irrespective of whether or not the seed structure is fertile or infertile. A plant part may be any part of the plant from which another plant may arise. “Rootstock” refers to a lower portion of a plant which includes the root system of the plant and may include a stem portion of the plant. As used herein, a rootstock may be used to grow a different variety through asexual propagation or reproduction such as grafting or through seeds. “Scion” refers to an upper portion of the plant which includes shoot or a stem which may have flowers, fruit or leaves. A scion may be from the same or a different plant type or variety. “Interstock” refers to an intermediate portion of a plant that is grafted between a rootstock and a scion.
[0086] As used herein, a promoter is a recognition site on a DNA sequence or group of DNA sequences that provides an expression control element for a structural gene and to which RNA polymerase specifically binds and initiates RNA synthesis (transcription) of that gene.
[0087] As used herein, “tolerance” encompasses any relief from, reduced presentation of, improvement of, or any combination thereof of any symptom of an infection by a Ca. Liberibacter species. As used herein, “resistance” encompasses tolerance as well as a reduction of bacterial load upon infection or reduction of ability to be infected by a Ca. Liberibacter species. Resistance to the bacterial infection can be determined by quantifying the copy number of the bacteria or bacterial titer in a given amount of plant genomic DNA. In specific embodiments, an unmodified plant or a plant pail exhibits bacterial copy number or bacterial titer that is at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 500% or any integer that isbetween 10 and 500%, more than the modified, resistant plant. In some embodiments, a modified resistant plant exhibits reduced symptoms of a disease relative to an unmodified plant. Some nonlimiting examples of the symptoms of the disease include decline in the fruit quality, decline in fruit quantity or reduced life span. In specific embodiments of the disclosure, citrus plants or solanaceous plants are provided that are tolerant or resistant to infection by a Ca. Liberibacter species and to HLB and / or ZC disease. This may be assessed, for example, relative to a citrus plant or a solanaceous plant of the same variety not comprising a corresponding genetic modification.
[0088] As used herein, the term “citrus” plant is used in its ordinary manner to refer to members of the family Rutacae, including, for example, sweet orange, bitter orange, blood orange, grapefruit, pomelo, citron, clementine, naval orange, lemon, lime, mandarin, tangerine, tangelo, and the like.
[0089] As used herein, the terms “solanaceous crop” or “solanaceous plant” are used interchangeably and are directed plants of the Solanacea family including, for example, tomato (Solanum lycopersicum and Solanum pennelli); potato (Solanum tuberosum); eggplant (Solatium melongena), bell / chili peppers (Capsicum annuum, Capsicum baccatum, and Capsicum chinense).Sec-Dependent Effector Proteins
[0090] Sec-dependent effector (SDE), as used herein, refers to any bacterial effector protein secreted from a bacterium via the Sec-dependent pathway. In specific embodiments, an SDE is secreted the Ca. Liberibacter species selected from the group consisting of Las, Laf, and Lam. In some specific embodiments, SDEs are CLIBASIA_04025 (Las4025) and CLIBASIA_05150 (Las5150) as described in Pang et al (Plant Physiol. 184(2):792-805, 2020) which is incorporated herein by reference in its entirety.Susceptibility Proteins (S-protein) Associated with Disease Resistance
[0091] A susceptibility protein or S-protein, as used herein, refers to an endogenous host polypeptide targeted by an SDE. A susceptibility gene or S-gene, as used herein, refers to an endogenous host gene encoding an S-protein. An S-protein-SDE complex, as used herein refers to an S-protein interacting with an SDE. An S-protein-SDE interaction is a protein-protein interaction between an S-protein and an SDE. In some embodiments, an S-gene is modified such that the encoded S-protein is no longer capable of interacting with an SDE. In some embodiments, an S- gene is modified such that the encoded S-protein may interact with an SDE, but not disrupt normalphysiology to an extent that a deleterious mechanism of action is triggered. As a non-limiting example, a modified S-gcnc may promote protcasomal degradation of an SDE-S-protcin complex before the complex activates a deleterious mechanism of action.
[0092] In some embodiments, one, two or more citrus S-proteins are modified.

[0128] The genome of a citrus or solanaccous plant, citrus or solanaccous rootstock, interstock and / or scion may be modified using one or more genome editing techniques. As used herein, “genome editing” and “genome-engineering” are terms used interchangeably and refer to the modification of a genome through mutagenesis. For example, in plant genome engineering, endonucleases may be used to generate double-strand DNA breaks (DSBs) and activate genome repair pathways. These DSB repair pathways may repair the break cleanly, i.e., without altering the starting sequence, or, alternatively, induce a mutation through an error in repair. In some embodiments, genome editing is used to insert, delete, or substitute one or more base pairs at one or any combination of genetic loci. In some embodiments, a genome editing technique is used to create a mutation, for example, a point mutation or single nucleotide polymorphism.
[0129] In some embodiments the DSB repair pathway is non-homologous end-joining (NHEJ) or microhomology mediated end joining (MMEJ). During NHEJ, any nucleotide overhangs on the break ends are either resected or filled to form blunt ends that are ligated. During MMEJ, the break ends are processed to reveal overhangs comprising microhomology sequences that are then ligated together. The insertions or deletions resulting from the terminal end processing in both the NHEJ and MMEJ pathways can be referred to as indels. In some embodiments, the NHEJ or MHEJ that occurs can be relied upon to introduce a genome modification including, but not limited to, a silent mutation, a neutral mutation, a missense mutation, a nonsense mutation, or a frameshift mutation.
[0130] In other embodiments, the DSB repair pathway is homologous recombination (HR). During HR, a DSB is repaired using a template with sequences with homology to the DNA flanking the break, i.e., a homologous chromosome. In plant genome editing, a linear DNA polynucleotide flanked by sequences (e.g., of 50 base pairs or more) homologous to those flanking a targeted genomic locus, may be introduced into the genome when a DSB is repaired by HR. In some embodiments, this approach is used to introduce, substitute, or delete a DNA sequence at a genomic locus. Any DNA sequence of interest may be introduced, deleted, or substituted. An introduced or substituted DNA sequence may encode an RNA molecule with a specific activity or function, a DNA molecule with a specific activity or function (e.g., encoding a polypeptide, representing a detectable marker, etc.), a DNA molecule comprising cis-regulatory elements, or a DNA molecule encoding a polypeptide, a motif thereof, or domain thereof. In some embodiments,the nucleic acid encoding the linear DNA sequence that will act as the HR template is encoded by an expression vector. In some embodiments, the nucleic acid encoding the linear DNA sequence of interest is encoded by a DNA sequence separate from the expression vector. For example, and without limitation, the nucleic acid encoding a DNA sequence of interest may be a linear DNA polynucleotide that is co-transformed with an expression vector.
[0131] In some embodiments, single-strand breaks or “nicks” are introduced into the target DNA sequence. As used herein, the term “single- strand break inducing agent” or “nickase” refers to any agent that can induce a single-strand break (SSB) in a DNA molecule. In some embodiments two SSBs are introduced into the target DNA to generate a DSB. These breaks may also be repaired by HR, NHEJ, or MMEJ. In some embodiments, sequence modifications occur at or near the SSB sites, which can include deletions or insertions that result in modification of the nucleic acid sequence, or integration of exogenous nucleic acids by HR or NHEJ.
[0132] In one aspect, a “modification” comprises the insertion of at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 25, at least 50, at least 100, at least 200, at least 300, at least 400, at least 500, at least 750, at least 1000, at least 1500, at least 2000, at least 3000, at least 4000, at least 5000, or at least 10,000 nucleotides.

In a further aspect, a “modification” comprises the inversion of at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 25, at least 50, at least 100, at least 200, at least 300, at least 400, at least 500, at least 750, at least 1000, at least 1500, at least 2000, at least 3000, at least 4000, at least 5000, or at least 10,000 nucleotides. In still another aspect, a “modification” comprises the substitution of at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 25, at least 50, at least 100, at least 200, at least 300, at least 400, at least 500, at least 750, at least 1000, at least 1500, at least 2000, at least 3000, at least 4000, at least 5000, or at least 10,000 nucleotides. In some embodiments, a “modification” comprises the substitution of an “A” for a “C,” “G” or “T” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of an “C” for an “A,” “G” or “T” in a nucleic acid sequence. In some embodiments, a“modification” comprises the substitution of a “G” for an “A,” “C” or “T” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of a “T” for an “A,” “C” or “G” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of a “C” for an “U” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of a “G” for an “A” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of an “A” for a “G” in a nucleic acid sequence. In some embodiments, a “modification” comprises the substitution of a “T” for a “C” in a nucleic acid sequence.
[0133] In some embodiments, genome editing of a citrus plant or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may encompass techniques that employ methods of targeting endonucleases to one or more genetic loci. In some embodiments, synthetic polypeptides, for example, Transcription Activator-Like Effectors (TALEs) and zinc fingers (ZFs), or nucleic acids, for example, Clustered Regularly Interspaced Short Palindromic Repeats / Cas (CRISPR / CAS) single guide RNAs or NgAgo (Argonaute) single strand DNAs, are used to target endonucleases to any genomic locus. The targeted endonucleases may catalyze a DSB at a target locus. Upon detecting these breaks, a cell may initiate any DSB repair pathway. In some embodiments, genome editing is carried out at more than one genomic locus simultaneously (i.e., multiplex genome engineering). In some embodiments, multiplex genome engineering may be used to remove a sequence of any size from the genome. In some embodiments, any combination and number of endonuclease targeting techniques may be used to target one or more genetic loci.RNA- and DNA-Guided Genome Editing Systems
[0134] In some embodiments, genome engineering of a citrus or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may employ RNA- guided endonucleases including, but not limited to CRISPR / Cas systems. CRISPR / Cas systems have been described in U.S. Patent Application Publication Nos. 2017 / 0191082 and 2017 / 0106025, each of which are incorporated herein by reference in their entirety. In some embodiments, a targeted genome modification as described herein comprises the use of at least one, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, or at least ten RNA-guided nucleases. In some embodiments, a CRISPR / Cas9 system,a CRISPR / Cpf 1 system, a CRISPR / CasX system, or a CRISPR / CasY system are alternatives that may be used to generate modifications to target sequences as described herein.
[0135] The CRISPR systems are based on RNA-guided endonucleases that use complementary base pairing to recognize DNA sequences at target sites. CRISPR / Cas systems are part of the adaptive immune system of bacteria and archaea, protecting them against invading DNA, such as viral DNA, by cleaving the foreign DNA in a sequence-dependent manner. The immunity is acquired by the integration of short fragments of the invading DNA known as spacers between two adjacent repeats at the proximal end of a CRISPR locus. The CRISPR arrays, including the spacers, are transcribed during subsequent encounters with invasive DNA and are processed into small interfering CRISPR RNAs (crRNAs) approximately 40 nt in length, which combine with the trans-activating CRISPR RNA (tracrRNA) to activate and guide the Cas9 nuclease. This cleaves homologous double- stranded DNA sequences known as protospacers in the invading DNA.
[0136] A prerequisite for cleavage is the presence of a conserved protospacer-adjacent motif (PAM) downstream of the target DNA, which usually has the sequence 5'-NGG-3' but less frequently NAG. Specificity is provided by the so-called “seed sequence” approximately 12 bases upstream of the PAM, which must match between the RNA and target DNA. Cpfl acts in a similar manner to Cas9, but Cpfl does not require a tracrRNA. Specificity of the CRISPR / Cas system is based on an RNA-guide that use complementary base pairing to recognize target DNA sequences. In some embodiments, the site-specific genome modification enzyme is a CRISPR / Cas system. In an aspect, a site-specific genome modification enzyme provided herein can comprise any RNA- guided Cas endonuclease (non-limiting examples of RNA-guided nucleases include Casl, CaslB, Cas2, Cas3, Cas4, Cas5, Cas6, Cas7, Cas8, Cas9 (also known as Csnl and Csxl2), CaslO, Csyl, Csy2, Csy3, Csel, Cse2, Cscl, Csc2, Csa5, Csn2, Csm2, Csm3, Csm4, Csm5, Csm6, Cmrl, Cmr3, Cmr4, Cmr5, Cmr6, Csbl, Csb2, Csb3, Csxl7, Csxl4, CsxlO, Csxl6, CsaX, Csx3, Csxl, CsxlS, Csfl, Csf2, Csf3, Csf4, Cpfl, homologs thereof, or modified versions thereof); and, optionally, the guide RNA necessary for targeting the respective nucleases.
[0137] In some embodiments, an RNA-guided endonuclease is the DNA cleavage domain of a restriction enzyme fused to a deactivated Cas9 (dCas9), for example dCas9-Fokl. As used herein, a “dCas9” refers to a endonuclease protein with one or more amino acid mutations that result in a Cas9 protein without endonuclease activity, but retaining RNA-guided site-specificDNA binding. As used herein, a “dCas9-restriction enzyme fusion protein” is a dCas9 with a protein fused to the dCas9 in such a manner that the restriction enzyme is catalytically active on the DNA.
[0138] In some embodiments, genome editing of a citrus or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may employ DNA-guided endonucleases including, but not limited to, N Ago systems. In one aspect, a method and / or composition provided herein comprises one or more, two or more, three or more, four or more, or five or more guide RNAs or DNAs. In another aspect, a CRISPR / CAS system, dCas9-restriction enzyme fusion protein, NgAgo system provided herein is capable of generating a targeted DSB in a target sequence as described herein. In one aspect, vectors comprising nucleic acids encoding one or more, two or more, three or more, four or more, or five or more guide RNAs or DNAs and the corresponding CRISPR / CAS system, dCas9-restriction enzyme fusion protein, NgAgo system are provided to a cell by transformation methods known in the art (e.g., without being limiting, viral transfection, particle bombardment, PEG-mediated protoplast transfection or Agrobacterium- mediated transformation).Transcription Activator-Like Effector Nucleases
[0139] In some embodiments, genome editing of a citrus or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may employ Transcription Activator-Like Effector Nucleases (TALENs). TALENs have been described in U.S. Patent Application Publication Nos. 2016 / 0369301 and 2015 / 0203871 (both of which are incorporated herein by reference in their entirety) and are well known in the art. TALENs are artificial restriction enzymes generated by fusing the transcription activator-like effector (TALE) DNA binding domain to an endonuclease domain. In one aspect, the nuclease is selected from a group consisting of PvuII, MutH, TevI and Fokl, Alwl, Mlyl, Sbll, Sdal, StsI, CleDORF, Clo051, Pept071. The term TALEN, as used herein, is broad and includes a monomeric TALEN that can cleave double stranded DNA without assistance from another TALEN. The term TALEN is also used to refer to one or both members of a pair of TALENs that work together to cleave DNA at the same site.
[0140] TALEs can be engineered to bind practically any DNA sequence, such as a target sequence as described herein. TALE proteins are DNA-binding domains derived from various plant bacterial pathogens of the genus Xanthomonas. The X pathogens secrete TALEs into the host plant cell during infection. The TALE moves to the nucleus, where it recognizes and bindsto a specific DNA sequence in the promoter region of a specific DNA sequence in the promoter region of a specific gene in the host genome. TALE has a central DNA-binding domain composed of 13-28 repeat monomers of 33-34 amino acids. The amino acids of each monomer are highly conserved, except for hypervariable amino acid residues at positions 12 and 13. The two variable amino acids are called repeat-variable diresidues (RVDs). The amino acid pairs NI, NG, HD, and NN of RVDs preferentially recognize adenine, thymine, cytosine, and guanine / adenine, respectively, and modulation of RVDs can recognize consecutive DNA bases. This simple relationship between amino acid sequence and DNA recognition has allowed for the engineering of specific DNA binding domains by selecting a combination of repeat segments containing the appropriate RVDs.
[0141] In one aspect, a method and / or composition provided herein comprises one or more, two or more, three or more, four or more, or five or more TALENs. In another aspect, a TALEN provided herein is capable of generating a targeted DSB in a target sequence as described herein. In one aspect, vectors comprising polynucleotides encoding one or more, two or more, three or more, four or more, or five or more TALENs are provided to a cell by transformation methods known in the art (e.g., without being limiting, viral transfection, particle bombardment, PEG-mediated protoplast transfection or Agrobacterium- mediated transformation).Zinc Finger Nucleases
[0142] In some embodiments, genome engineering of a citrus or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may employ Zinc Finger Nucleases (ZFNs). ZFNs have been described in U.S. Pat. No. 9,322,006 (incorporated herein by reference in its entirety) and are well known in the art. ZFNs are synthetic proteins consisting of an engineered zinc finger DNA-binding domain fused to the cleavage domain of an endonuclease, for example, Fokl. ZFNs can be designed to cleave almost any long stretch of double-stranded DNA by the modification of the zinc finger DNA-binding domain. ZFNs form dimers from monomers composed of a non-specific DNA cleavage domain of Fokl nuclease fused to a zinc finger array engineered to bind a target DNA sequence. The DNA-binding domain of a ZFN is typically composed of 3-4 zinc-finger arrays. The amino acids at positions -1, +2, +3, and +6 relative to the start of the zinc finger co-helix, which contribute to site-specific binding to the target DNA, can be changed and customized to fit specific target sequences. The other amino acids form the consensus backbone to generate ZFNs with different sequence specificities. Rules forselecting target sequences for ZFNs are known in the art. The FokI nuclease domain requires dimerization to cleave DNA and therefore two ZFNs with their C-tcrminal regions arc needed to bind opposite DNA strands of the cleavage site (separated by 5-7 nt). The ZFN monomer can cut the target site if the two-ZF-binding sites are palindromic. The term ZFN, as used herein, is broad and includes a monomeric ZFN that can cleave double stranded DNA without assistance from another ZFN. The term ZFN is also used to refer to one or both members of a pair of ZFNs that are engineered to work together to cleave DNA at the same site.
[0143] Without being limited by any scientific theory, because the DNA-binding specificities of zinc finger domains can in principle be re-engineered using one of various methods, customized ZFNs can theoretically be constructed to target nearly any gene sequence. Publicly available methods for engineering zinc finger domains include Context-dependent Assembly (CoDA), Oligomerized Pool Engineering (OPEN), and Modular Assembly.
[0144] Several embodiments relate to a method and / or composition provided herein comprising one or more, two or more, three or more, four or more, or five or more ZFNs directed to a target sequence as described herein. In another aspect, a ZFN provided herein is capable of generating a targeted DSB. In one aspect, vectors comprising polynucleotides encoding one or more, two or more, three or more, four or more, or five or more ZFNs are provided to a cell by transformation methods known in the art (e.g., without being limiting, viral transfection, particle bombardment, PEG-mediated protoplast transfection or Agrobacterium-mediated transformation).Meganucleases
[0145] In some embodiments, genome engineering of a citrus or a solanaceous plant, citrus or solanaceous rootstock, interstock and / or scion as described herein may employ a meganuclease. Meganucleases, which are commonly identified in microbes, are unique enzymes with high activity and long recognition sequences (>14 nt) resulting in site-specific digestion of target DNA. Engineered versions of naturally occurring meganucleases typically have extended DNA recognition sequences (for example, 14 to 40 nt). The engineering of meganucleases can be more challenging than that of ZFNs and TALENs because the DNA recognition and cleavage functions of meganucleases are intertwined in a single domain. Specialized methods of mutagenesis and high-throughput screening have been used to create novel meganuclease variants that recognize unique sequences and possess improved nuclease activity.
[0146] In one aspect, a method and / or composition provided herein comprises one or more, two or more, three or more, four or more, or five or more mcganuclcascs directed to a target sequence as described herein. In some embodiments, a meganuclease provided herein is capable of generating a targeted DSB. In some embodiments, vectors comprising polynucleotides encoding one or more, two or more, three or more, four or more, or five or more meganucleases are provided to a cell by transformation methods known in the art (e.g., without being limiting, viral transfection, particle bombardment, PEG-mediated protoplast transfection or Agrobacterium- mediated transformation).Site-Specific Genome Modification
[0147] The genome of a citrus or a solanaceous plant can be modified using sitespecific genome modification techniques. In some embodiments, site-specific genome modification of a citrus or a solanaceous plant as described herein may employ any site-specific genome modification enzyme. As used herein, the term “site- specific genome modification enzyme” refers to any enzyme that can modify a nucleotide sequence in a sequence-specific manner. In some embodiments, a site-specific genome modification enzyme modifies the genome by inducing a single-strand break. In some embodiments, a site-specific genome modification enzyme modifies the genome by inducing a double-strand break. In some embodiments, a sitespecific genome modification enzyme is a recombinase. In some embodiments, a site-specific genome modification enzyme is a transposase. In the present disclosure, site-specific genome modification enzymes include, but are not limited to, nucleases, endonucleases, recombinases, invertases, transposases, methytransferase, demethlylases, aminases, deaminases, helicases, and any combination thereof.
[0148] In some embodiments, the site-specific genome modification enzyme is a recombinase. Non-limiting examples of recombinases include a tyrosine and serine recombinases and coupled with a DNA recognition motif, for example, a Cre recombinase, a Gin recombinase, a Flp recombinase, and a Tnpl recombinase. In another aspect, a serine recombinase coupled with a DNA recognition motif, for example, a PhiC31 integrase, an R4 integrase, and a TP-901 integrase. In an aspect, a recombinase is tethered to a zinc-finger DNA-binding domain, or a TALE DNA-binding domain, or a Cas9 nuclease.
[0149] The Flp-FRT site-directed recombination system comes from the 2p plasmid from the baker’s yeast Saccharomyces cerevisiae. In this system, Flp recombinase (flippase)recombines sequences between flippase recognition target (FRT) sites. FRT sites comprise 34 nucleotides. Flp binds to the “arms” of the FRT sites (one arm is in reverse orientation) and cleaves the FRT site at either end of an intervening nucleic acid sequence. After cleavage, Flp recombines nucleic acid sequences between two FRT sites.
[0150] Cre-lox is a site-directed recombination system derived from the bacteriophage Pl that is similar to the Flp-FRT recombination system. Cre-lox can be used to invert a nucleic acid sequence, delete a nucleic acid sequence, or translocate a nucleic acid sequence. In this system, Cre recombinase recombines a pair of lox nucleic acid sequences. Lox sites comprise 34 nucleotides, with the first and last 13 nucleotides (arms) being palindromic. During recombination, Cre recombinase protein binds to two lox sites on different nucleic acids and cleaves at the lox sites. The cleaved nucleic acids are spliced together (reciprocally translocated) and recombination is complete. In another aspect, a lox site provided herein is a loxP, lox 2272, loxN, lox 511, lox 5171, lox71, lox66, M2, M3, M7, or Mil site.
[0151] In another aspect, the site-specific genome modification enzyme is a dCas9- recombinase fusion protein. As used herein, a “dCas9-recombinase fusion protein” is a dCas9 with a protein fused to the dCas9 in such a manner that the recombinase is catalytically active on the DNA. In some embodiments, dCas9 may be fused with the catalytic domain of any enzyme such that the catalytic domain is catalytically active on DNA. In another aspect, a DNA transposase is attached to a DNA binding domain for example, a TALE-piggyBac and TALE-Mutator.
[0152] Several embodiments relate to promoting DNA recombination by providing a site-specific genome modification enzyme to a plant cell. In some embodiments, recombination is promoted by providing a strand separation inducing reagent. In one aspect, the site-specific genome modification enzyme is selected from an endonuclease, a recombinase, an invertase, a transposase, a helicase or any combination thereof. In some embodiments, recombination occurs between B chromosomes. In some embodiments, recombination occurs between a B chromosome and an A chromosome.
[0153] Several embodiments relate to promoting integration of one or more DNAs of interest by providing a site-specific genome modification enzyme. In some embodiments, integration of one or more DNAs of interest is promoted by providing a strand separation inducing reagent. In one aspect, the site- specific genome modification enzyme is selected from an endonuclease, a recombinase, a transposase, a helicase or any combination thereof. Any DNAsequence can be integrated into a target site of a chromosome sequence by introducing the DNA sequence and the provided site- specific genome modification enzymes. Any method provided herein can utilize any site-specific genome modification enzyme provided herein.
[0154] Several embodiments relate to a method and / or a composition provided herein comprising at least one, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, or at least ten site-specific genome modification enzymes. In yet another aspect, a method and / or a composition provided herein comprises at least one, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, or at least ten polynucleotides encoding at least one, at least two, at least three, at least four, at least five, at least six, at least seven, at least eight, at least nine, or at least ten site- specific genome modification enzymes.Antisense and RNAi Constructs
[0155] In the methods and compositions of the present disclosure, endogenous gene activity can be down-regulated by any means known in the art, including through the use of ribozymes or aptamers. Endogenous gene activity can also be down-regulated with an antisense or RNAi molecule.
[0156] In particular, constructs comprising a coding sequence, including fragments thereof, in antisense orientation, or combinations of sense and antisense orientation, may be used to decrease or effectively eliminate the expression of the gene in a plant such as a citrus tree or variety. Accordingly, this may be used to “knock-out” the function of the coding sequence or homologous sequences thereof.
[0157] Techniques for RNAi are well known in the art and are described in, for example, Lehner et al., (2004) and Downward (2004). The technique is based on the ability of double stranded RNA to direct the degradation of messenger RNA with sequence complementary to one or the other strand (Fire et al., 1998). Therefore, by expression of a particular coding sequence in sense and antisense orientation, either as a fragment or longer portion of the corresponding coding sequence, the expression of that coding sequence can be down-regulated.
[0158] Antisense and in some aspects RNAi, methodology takes advantage of the fact that nucleic acids tend to pair with “complementary” sequences. By complementary, it is meant that polynucleotides are those which are capable of base-pairing according to the standard Watson / Crick complementarity rules. That is, the larger purines will base pair with the smallerpyrimidines to form combinations of guanine paired with cytosine (G:C) and adenine paired with either thymine (A:T) in the case of DNA, or adenine paired with uracil (A:U) in the case of RNA. Inclusion of less common bases such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthine and others in hybridizing sequences does not interfere with pairing.
[0159] Targeting double-stranded (ds) DNA with polynucleotides leads to triple-helix formation; targeting RNA will lead to double-helix formation. Antisense oligonucleotides, when introduced into a target cell, specifically bind to their target polynucleotide and interfere with transcription, RNA processing, transport, translation and / or stability. Antisense and RNAi constructs, or DNA encoding such RNA’s, may be employed to inhibit gene transcription or translation or both within a host cell, either in vitro or in vivo, such as within a host plant cell. In certain embodiments of the disclosure, such an oligonucleotide may comprise any unique portion of a nucleic acid sequence provided herein. In certain embodiments of the disclosure, such a sequence comprises at least 18, 30, 50, 75, or 100 or more contiguous nucleic acids of the nucleic acid sequence of a gene, and / or complements thereof, which may be in sense and / or antisense orientation. By including sequences in both sense and antisense orientation, increased suppression of the corresponding coding sequence may be achieved.
[0160] Constructs may be designed that are complementary to all or part of the promoter and other control regions, exons, introns or even exon-intron boundaries of a gene. It is contemplated that the most effective constructs may include regions complementary to intron / exon splice junctions. Thus, it is proposed that an embodiment includes a construct with complementarity to regions within 50-200 bases of an intron-exon splice junction. It has been observed that some exon sequences can be included in the construct without seriously affecting the target selectivity thereof. The amount of exonic material included will vary depending on the particular exon and intron sequences used. One can readily test whether too much exon DNA is included simply by testing the constructs in vitro to determine whether normal cellular function is affected or whether the expression of related genes having complementary sequences is affected.
[0161] As stated above, “complementary” or “antisense” means polynucleotide sequences that are substantially complementary over their entire length and have very few base mismatches. For example, sequences of fifteen bases in length may be termed complementary when they have complementary nucleotides at thirteen or fourteen positions. Naturally, sequences which are completely complementary will be sequences which are entirely complementarythroughout their entire length and have no base mismatches. Other sequences with lower degrees of homology also arc contemplated. For example, an RNAi or antisense construct which has limited regions of high homology, but also contains a non-homologous region (e.g., as in a ribozyme) could be designed. Methods for selection and design of sequences that generate RNAi are well known in the art (e.g. Reynolds, 2004). These molecules, though having less than 50% homology, would bind to target sequences under appropriate conditions.
[0162] It may be advantageous to combine portions of genomic DNA with cDNA or synthetic sequences to generate specific constructs. For example, where an intron is desired in the ultimate construct, a genomic clone will need to be used. The cDNA or a synthesized polynucleotide may provide more convenient restriction sites for the remaining portion of the construct and, therefore, would be used for the rest of the sequence. Constructs useful for generating RNAi may also comprise concatemers of sub-sequences that display gene regulating activity.Plant Transformation Constructs
[0163] Vectors used for plant transformation may include any vector that is generally known in the art. Some non-limiting examples of the vectors that can be used areplasmids, cosmids, YACs (yeast artificial chromosomes), BACs (bacterial artificial chromosomes) or any other suitable cloning system, as well as fragments of DNA therefrom. Thus, when the term “vector” or “expression vector” is used, all of the foregoing types of vectors, as well as nucleic acid sequences isolated therefrom, are included. In some embodiments, a viral vector based on a plant virus such as a Citrus Tristeza Virus may be used in accordance with the disclosure. It is contemplated that utilization of cloning systems with large insert capacities will allow introduction of large genetic sequences comprising more than one selected gene. In accordance with the disclosure, this could be used to introduce genetic material corresponding to an entire biosynthetic pathway into a plant. Introduction of such sequences may be facilitated by use of bacterial or yeast artificial chromosomes (BACs or YACs, respectively), or even plant artificial chromosomes. For example, the use of BACs for Agrobacterium-mediated transformation was disclosed by Hamilton et al. (1996).
[0164] Particularly useful for transformation arc expression cassettes that have been isolated from such vectors. DNA segments used for transforming plant cells will, of course, generally comprise the cDNA, gene or genes which one desires to introduce into and haveexpressed in the host cells. These DNA segments can further include structures such as promoters, enhancers, polylinkers, or even regulatory genes as desired. The DNA segment or gene chosen for cellular introduction will often encode a protein which will be expressed in the resultant genetically modified cells resulting in a screenable or selectable trait and / or will impart an improved phenotype to the resulting genetically modified plant. However, this may not always be the case, and the present disclosure also encompasses genetically modified plants incorporating nonexpressed transgenes.
[0165] In accordance with the disclosure, a nucleic acid vector comprising a coding sequence may be introduced into a plant such as a citrus tree or variety, such that, when the vector is transformed into a citrus variety or plant as described herein, the coding sequence is expressed in the plant. In some embodiments the coding sequence may be expressed in, for example, the phloem or roots of the plant, or any other part of the plant. Expression of the coding sequence in the resulting genetically modified citrus tree or variety results in the tree exhibiting increased tolerance or resistance to HLB when compared to a tree lacking expression of the coding sequence.Methods of Genetic transformation
[0166] Suitable methods for transformation of plant or other cells for use with the current disclosure are believed to include virtually any method by which DNA can be introduced into a cell, such as by direct delivery of DNA such as by PEG-mediated transformation of protoplasts, desiccation / inhibition-mediated DNA uptake, electroporation, nanoparticle mediated gene transformation, ribonucleoprotein complex mediated transformation, Agrobacterium- mediated transformation and acceleration of DNA coated particles, etc. Through the application of techniques such as these, the cells of virtually any plant species may be stably transformed, and these cells developed into genetically modified plants.
[0167] Agro / ?acterzMm-mediated transfer is a widely applicable system for introducing genes into plant cells because the DNA can be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. The use of Agrobacterium- mediated plant integrating vectors to introduce DNA into plant cells is well known in the art.
[0168] Another method for delivering transforming DNA segments to plant cells in accordance with the disclosure is microprojectile bombardment (U.S. Pat. Nos. 5,550,318; 5,538,880; 5,610,042; and PCT Application WO 94 / 09699; each of which is specificallyincorporated herein by reference in its entirety). In this method, particles may be coated with nucleic acids and delivered into cells by a propelling force.
[0169] Another method for plant transformation is PEG-mediated transformation, which can be used to deliver plasmids or ribonucleoproteins, and can be used to introduce transformation without introduction of foreign material in TO plants.Production of plants after genomic editing
[0170] In addition to direct transformation of a particular plant genotype with a construct prepared according to the current disclosure, genetically modified plants may be made by crossing a plant having a selected genetic modification of the disclosure to a second plant lacking the modification. For example, a selected lignin biosynthesis coding sequence can be introduced into a particular plant variety by crossing, without the need for ever directly transforming a plant of that given variety. Therefore, the current disclosure not only encompasses a plant directly modified or regenerated from cells which have been modified in accordance with the current disclosure, but also the progeny of such plants.
[0171] As used herein the term “progeny” denotes the offspring of any generation of a parent plant prepared in accordance with the instant disclosure, wherein the progeny comprises a selected DNA construct. “Crossing” a plant to provide a plant line having one or more added transgenes relative to a starting plant line, as disclosed herein, is defined as the techniques that result in a coding sequence of the disclosure being introduced into a plant line by crossing a starting line with a donor plant line that comprises a first selected DNA of the disclosure. To achieve this in a plant such as a citrus tree one could, for example, perform the following steps:(a) plant seeds of the first (starting line) and second (donor plant line that comprises a first selected DNA of the disclosure) parent plants;(b) grow the seeds of the first and second parent plants into plants that bear flowers;(c) pollinate a flower from the first parent plant with pollen from the second parent plant; and(d) harvest seeds produced on the parent plant bearing the fertilized flower.
[0172] Backcrossing is herein defined as the process including the steps of:(a) crossing a plant of a first genotype containing a desired gene, DNA sequence or element to a plant of a second genotype lacking the desired gene, DNA sequence or element;(b) selecting one or more progeny plant containing the desired gene, DNA sequence or element;(c) crossing the progeny plant to a plant of the second genotype; and(d) repeating steps (b) and (c) for the purpose of transferring a desired DNA sequence from a plant of a first genotype to a plant of a second genotype.
[0173] Introgression of a DNA element into a plant genotype is defined as the result of the process of backcross conversion. A plant genotype into which a DNA sequence has been introgressed may be referred to as a backcross converted genotype, line, inbred, or hybrid. Similarly a plant genotype lacking the desired DNA sequence may be referred to as an unconverted genotype, line, inbred, or hybrid.
[0174] In some embodiments, asexual reproduction or propagation may be used to obtain a progeny plant in accordance with the disclosure. Techniques to achieve asexual propagation or reproduction in citrus trees or varieties may include, for example, grafting, budding, top-working, layering, runner division, cuttings, rooting, T-budding, and the like. In some embodiments, one citrus variety into which a coding sequence has been introduced may be grafted onto the rootstock of another variety. In other embodiments, a coding sequence may be introduced into the rootstock. In either of these situations, one or both of the plant varieties may exhibit increased tolerance or resistance to HLB.Modified Plants

[0259] To determine whether the HLB susceptibility genes would translate to zebra chip susceptibility genes, blastp was performed to examine the similarities between the proteins translated from the citrus genes and potato and tomato genes. The two priority target susceptibility genes for citrus have close homologs in both potatoes and tomatoes. Table 1 lists the gene targets as well as the blastp e-values for the corresponding proteins.TABLE 1 - TARGET GENE LISTS
[0260] To determine if the susceptibility and resistance genes identified in citrus for HLB will function similarly in tomatoes, and likely potatoes, for zebra chip disease. Six CRISPR- edited lines of tomato plants were created with approximately 100 total plants, targeting priority genes predicted to confer resistance to zebra chip disease. The CRISPR-edited tomatoes and wildtype control tomatoes against CLso were tested by exposing them to CLso-infected psyllids. The tomatoes where the Llsl homolog PTC and the cysteine protease homolog Cyp were editedshowed strong resistance to CLso as compared to the non-edited plants. The plants exhibited either no symptoms or only mild to medium symptoms during the first 11 weeks of the experiment, while on average mortality occurred in the control plants at week 8 as shown in Figures 1A, IB and 1C.Example 2 - Protoplast transfection and regeneration
[0261] Gene editing of plant cells were performed by transfecting plant protoplasts with gRNA containing plasmids (e.g., pSMulti-ACD2gD / Lls 1 gB plasmid that contains GFP reporter gene). The plasmid was transfected into Valencia, Carizzo and Hamlin protoplasts using the PEG-mediated transfection method and the GFP signal was examined in pSMulti- ACD2gD / LlslgBAran iec protoplast under the microscope. The results showed that the plasmid uptake was very high in both Valencia and Hamlin protoplasts (data not shown), which confirmed that the protoplast transfection method was not only successful, but also highly effective as shown in Figure 2.
[0262] Through the protoplast transfection, up to 88% and 95% gene editing efficiencies of the protoplast were obtained using pSMulti-Cl-86 / C3-g5 plasmid and 48% using C2-213 plasmid as shown in Table 2. The first few sets of protoplast regenerants yielded Valencia plants with edits to both the C 1-86 and C3-5 genes with no foreign DNA inserted into the genome.TABLE 2
[0263] Following the protoplast transfection, protoplasts were regenerated into plantlets and were able to produce a non-transgenic Valencia plant with individual edits to ACD2gD, LlslgB, and CPgC, as well as plants with a double edit to both the ACD2gD and the LlslgB genes as shown in Figures 3A-3C and 4A-D.Example 3- Double and Triple gene editing of HLB Susceptibility genes in Citrus Plants confer stronger resistance to HLB
[0264] To determine if double and triple-edited citrus plants show a stronger resistance to HLB as compared with single gene edited plants, gene editing of the Valencia, Carrizo and Hamlin plant cells were performed by transfecting plant protoplasts with gRNA containing plasmids. The plasmids were transfected into Valencia, Carrizo and Hamlin protoplasts using the PEG-mediated transfection method. Following the protoplast transfection, protoplasts were regenerated into plantlets and were able to produce a non-transgenic Valencia, Hamlin and Carrizo plants with individual edits to ACD2gD, LlslgB, and CPgC, as well as plants with a double edit to both the ACD2gD and the LlslgB genes, and triple edits to ACD2gD, LlslgB, and CPgC genes as shown in Figures 5A-E, 6A-C, 7A-B, 8A-D and 9A-D. Grafting of wild-type Hamlin plant on wild-type Carrizo and wild-type Hamlin plant on wild-type Carrizo were also performed to generate plants as illustrated in FIGS. 11A and 1 IB.
[0265] After HLB graft and psyllid inoculation, edited trees were analyzed through qPCR to confirm that the psyllids did infect the trees with CLas and through visible HLB symptom evaluation. As shown in Figure 10A, while single edits to Llsl, ACD2, and CP genes in the citrus plants exhibited some resistance against HLB, the double-edited citrus plants to both ACD2gD and LlslgB exhibited the strongest resistance to HLB as shown by a reduced copy number of CLas per 100 ng plant gDNA or RNA in leaf midvein or hairy root tissue of edited citrus plants two years, post inoculation with CLas.
[0266] Additionally, the citrus trees were assessed for characteristic HLB symptoms such as blotchy mottling, corky veins, and dieback. As shown in Figure 10B, while single edits to Lis 1 , ACD2, and CP genes in the citrus plants exhibited some resistance to HLB as compared to WT, the double-edited citrus trees to both ACD2gD and LlslgB exhibited increased resistance.Example 4- Gene editing of HLB Susceptibility genes in Citrus rootstock trees confer stronger resistance to HLB
[0267] To determine if edited citrus rootstock trees show a stronger resistance to HLB as compared with control rootstock trees, gene editing of the Valencia, Carrizo and Hamlin rootstock plant cells were performed by transfecting plant protoplasts with gRNA containing plasmids. The plasmids were transfected into Valencia, Carrizo and Hamlin protoplasts using the PEG-mediated transfection method. Following the protoplast transfection, protoplasts were regenerated into plantlets and were able to produce a non-transgenic Valencia, Hamlin and Carrizorootstock trees with individual edits to ACD2, Llsl , PP2-B12 and CP, as well as plants with a double edit to ACD2 and Llsl and triple edit to both the ACD2, CP and the Llsl genes, and triple edits to ACD2, Llsl, and CP genes. CRISPR-edited Carrizo rootstock with single edits to ACD2, PP2-B 12 and CP, double edits to ACD2 and Lis 1 in a Carrizo interstock of HLB diseased Rangpur lime scion and Carrizo rootstock and triple edits at ACD2, Lis 1 and CP genes as shown in Figures 12A-G.
[0268] Grafting of edited plants with edited or wild-type rootstock of other varieties was performed. Figures 13A and 13B illustrate -grafting of CRISPR-edited Hamlin plant targeting Llsl on wild-type US-942 rootstock (FIG. 13A)) and wild-type Hamlin on CRISPR-edited rootstock targeting Llsl gene (FIG. 13B).
[0269] To analyze if gene editing of HLB Susceptibility genes in Citrus rootstock trees confer stronger resistance to HLB, HLB-infected Valencia scion was grafted onto control wildtype Carrizo rootstock as illustrated in FIG. 14A. Additionally, HLB-infected Rangpur Lime scion was grafted onto control wild-type Carrizo rootstock and Carrizo stock edited at PP2-B12 as illustrated in FIG.14B and 14C. As illustrated in FIG. 14C, lime scion grafted onto PP2-B 12 edited rootstock showed a stronger resistance to HLB as compared with wild-type Carrizo rootstock grafted lime scion.
[0270] After HLB grafting and psyllid inoculation, edited rootstock trees were analyzed through qPCR to confirm that the psyllids did infect the trees with CLas and through visible HLB symptom evaluation. As shown in Figure 15 A, while single edits to Llsl, ACD2, and CP genes in the citrus rootstock trees exhibited some resistance against HLB, the double-edited citrus plants to both ACD2gD and LlslgB exhibited the strongest resistance to HLB as shown by a reduced copy number of CLas per 100 ng plant gDNA or RNA in leaf midvein or hairy root tissue of edited citrus rootstock trees three years, post inoculation with CLas.
[0271] Additionally, the citrus rootstock trees were assessed for characteristic HLB symptoms such as blotchy mottling, corky veins, and dieback. As shown in Figure 15B, while single edits to Llsl, ACD2, and CP genes in the citrus rootstock trees exhibited some resistance to HLB as compared to WT, the double-edited citrus rootstock trees to both ACD2gD and LlslgB exhibited increased resistance.
