[0260] Terms used in the claims and specification are defined as set forth below unless otherwise specified. As used in this specification and the appended claims, the singular forms "a," "an," and "the" unless the context clearly dictates otherwise. It should be noted that it includes multiple referents.
[0261] As used herein, "nucleic acid" means a polynucleotide and includes single- or double-stranded polymers of deoxyribonucleotide or ribonucleotide bases. Nucleic acids can also include fragments and modified nucleotides. Accordingly, the terms "polynucleotide", "nucleic acid sequence", "nucleotide sequence" and "nucleic acid fragment" are used to denote polymers of RNA and / or DNA and / or RNA-DNA that are single- or double-stranded. Used interchangeably, optionally includes synthetic, non-natural or altered nucleotide bases. Nucleotides (usually found in the 5'-monophosphate form) are designated by their single letter designations: "A" for adenosine or deoxyadenosine (for RNA or DNA respectively), cytosine or deoxy "C" for cytosine, "G" for guanosine or deoxyguanosine, "U" for uridine, "T" for deoxythymidine, "R" for purine (A or G), "Y" for pyrimidine (C or T), "K" for G or T, "H" for A or C or T, "I" for inosine and "N" for any nucleotide.
[0262] The term "genome" when applied to prokaryotic and eukaryotic cells or biological cells includes not only chromosomal DNA found within the nucleus, but also organellar DNA found within the cellular components of the cell (e.g. mitochondria or plastids). do.
[0263] "Open reading frame" is abbreviated ORF.
[0264] The term "selectively hybridizes" includes specific nucleic acid target sequences relative to hybridization to non-target nucleic acid sequences and substantial exclusion of non-target nucleic acids under stringent hybridization conditions. Included is reference to a detectably large degree (eg, at least 2-fold over background) of hybridization to. Selectively hybridizing sequences typically have at least 80% sequence identity or 90% sequence identity and up to 100% sequence identity (ie, fully complementary) to each other.
[0265] The terms "stringent conditions" or "stringent hybridization conditions" include conditions under which a probe will selectively hybridize to its target sequence in an in vitro hybridization assay. Stringent conditions are sequence-dependent and will be different in different circumstances. By controlling the stringency of hybridization and / or washing conditions, target sequences that are 100% complementary to the probe can be identified (homologous probing). Alternatively, stringency conditions can be adjusted to allow some sequence mismatches such that lower similarities are detected (non-homologous probing). Generally, probes are less than about 1000 nucleotides in length, optionally less than 500 nucleotides in length. Generally, stringent conditions are pH 7.0-8.3 and at least about 30° C. for short probes (eg, 10-50 nucleotides) and at least At a temperature of about 60°C, the salt concentration is about 1.5 M Na ion concentration, typically about 0.01 to 1.0 M Na ion concentration. Stringent conditions may also be created with the addition of destabilizing substances such as formamide. Examples of low stringency conditions include hybridization with a buffer consisting of 30-35% formamide, 1 M NaCl, 1% SDS (sodium dodecyl sulfate) at 37°C and 1-2 x SSC at 50-55°C. Washing in (20×SSC=3.0M NaCl / 0.3M sodium citrate) is included. Examples of moderate stringency conditions include hybridization in 40-45% formamide, 1M NaCl, 1% SDS at 37°C and washing in 0.5-1 x SSC at 55-60°C. Examples of high stringency conditions include hybridization in 50% formamide, 1M NaCl, 1% SDS at 37°C and washing in 0.1 x SSC at 60-65°C.
[0266] "Homology" means similar DNA sequences. For example, a "region of homology to a genomic region" found on donor DNA is a region of DNA that has sequence similarity to a given "genomic region" of a fungal cell genome. A homologous region can be of any length sufficient to promote homologous recombination at the target site to be cleaved. For example, the region of homology may be at least 5-10, 5-15, 5-20, 5-25, 5-25, 5-10, 5-15, 5-25 in length, such that the region of homology has sufficient homology to undergo homologous recombination with the corresponding genomic region. 5~30, 5~35, 5~40, 5~45, 5~50, 5~55, 5~60, 5~65, 5~70, 5~75, 5~80, 5~85, 5~ 90, 5~95, 5~100, 5~200, 5~300, 5~400, 5~500, 5~600, 5~700, 5~800, 5~900, 5~1000, 5~1100, 5~1200, 5~1300, 5~1400, 5~1500, 5~1600, 5~1700, 5~1800, 5~1900, 5~2000, 5~2100, 5~2200, 5~2300, 5~ 2400, 5-2500, 5-2600, 5-2700, 5-2800, 5-2900, 5-3000, 5-3100 or more bases in length. "Sufficient homology" indicates that two polynucleotide sequences have sufficient structural similarity to act as substrates for a homologous recombination reaction. This structural similarity includes the full length of each polynucleotide fragment and the sequence similarity of the polynucleotides. Sequence similarity includes percent sequence identity over the entire length of the sequence and / or percent sequence identity over a portion of the length of the sequence and conserved regions including localized similarity such as contiguous nucleotides with 100% sequence identity can be explained by
[0267] As used herein, a "genomic region" is a segment of a chromosome in the genome of a cell that is on either side of a target site, or alternatively a segment that also contains part of the target site. be. This genomic region is at least 5-10, 5-15, 5-20, 5-25, 5-30, 5-35, 5-40, 5-45, 5-50, 5-55, 5-60, 5~65, 5~70, 5~75, 5~80, 5~85, 5~90, 5~95, 5~100, 5~200, 5~300, 5~400, 5~500, 5~ 600, 5~700, 5~800, 5~900, 5~1000, 5~1100, 5~1200, 5~1300, 5~1400, 5~1500, 5~1600, 5~1700, 5~1800, 5~1900, 5~2000, 5~2100, 5~2200, 5~2300, 5~2400, 5~2500, 5~2600, 5~2700, 5~2800, 5~2900, 5~3000, 5~ It can contain 3100 bases or more so that this genomic region has sufficient homology to undergo homologous recombination with the corresponding homologous region.
[0268] As used herein, "homologous recombination" (HR) involves the exchange of DNA fragments between two DNA molecules at homologous sites. The frequency of homologous recombination is influenced by many factors. The amount of homologous recombination and the relative proportions of homologous and non-homologous recombination vary between different organisms. In general, the length of the region of homology affects the frequency of homologous recombination events, the longer the region of homology, the higher the frequency. The length of the homologous region required for observation of homologous recombination also varies depending on the species. In many cases, homology of at least 5 kb has been exploited, but homologous recombination with homology as small as 25-50 bp has been observed. For example, Singer et al., (1982) Cell 31:25-33; Shen and Huang, (1986) Genetics 112:441-57; Watt et al., (1985) Proc. 4768-72, Sugawara and Haber, (1992) Mol Cell Biol 12:563-75, Rubnitz and Subramani, (1984) Mol Cell Biol 4:2253-8; Ayares et al., 1986) Proc. Natl. Acad. USA 83:5199-203; Liskay et al., (1987) Genetics 115:161-7.
[0269] "Sequence identity" or "identity", in the context of nucleic acid or polypeptide sequences, refers to the nucleobases or Refers to amino acid residues.
[0270] The term "percentage of sequence identity" refers to a value determined by comparing two optimally aligned sequences over a comparison window, wherein the portions of the polynucleotide or polypeptide sequences within the comparison window are those In order to optimally align two sequences, additions or deletions (ie, gaps) may be included as compared to a reference sequence (containing no additions or deletions). The percentage is determined by determining the number of positions in both sequences where the same nucleobase or amino acid residue occurs, yielding the number of matched positions, and dividing the number of matched positions by the total number of positions in the comparison window. and multiply the result by 100 to obtain the percentage sequence identity. Useful examples of percent sequence identity include 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% or any percentage from 50% to 100%. include, but are not limited to. These identities can be determined using any of the programs described herein.
[0271] Sequence alignments and percent identity or similarity calculations can be performed using, but not limited to, the MegAlign™ program of the LASERGENE bioinformatics computing suite (DNASTAR Inc., Madison, Wis.) to detect homologous sequences. It can be determined using a variety of designed comparison methods. In the context of this application, when sequence analysis software is used for analysis, it will be understood that analysis results are based on the "default values" of the mentioned programs unless otherwise specified. As used herein, "default values" shall mean any set of values or parameters that are initially loaded with the software when first initialized.
[0272] The "Clustal V method of alignment" is denoted Clustal V (described by Higgins and Sharp, (1989) CABIOS 5:151-153; Higgins et al., (1992) Comput Appl Biosci 8:189-191). and corresponds to the alignment method found in the MegAlign™ program of the LASERGENE Bioinformatics Computing Suite (DNASTAR Inc., Madison, Wis.). For multiple alignments, the default values correspond to GAP PENALTY=10 and GAP LENGTH PENALTY=10. The default parameters for pairwise alignments of protein sequences and calculation of percent identity using the Clustal method are KTUPLE=1, GAP PENALTY=3, WINDOW=5 and DIAGONALS SAVED=5. For nucleic acids, these parameters are KTUPLE=2, GAP PENALTY=5, WINDOW=4 and DIAGONALS SAVED=4. After alignment of sequences using the Clustal V program, "percent identity" can be obtained by looking up the "sequence distance" table in the same program. The "Clustal W method of alignment" is labeled Clustal W (described by Higgins and Sharp, (1989) CABIOS 5:151-153; Higgins et al., (1992) Comput Appl Biosci 8:189-191). and corresponds to the alignment method found in the MegAlign™ v6.1 program of the LASERGENE Bioinformatics Computing Suite (DNASTAR Inc., Madison, Wis.). Default parameters for multiple alignments (GAP PENALTY=10, GAP LENGTH PENALTY=0.2, Delay Divergen Seqs(%)=30, DNA Transition Weight=0.5, Protein Weight Matrix=Gonnet Series, DNA Weight Matrix=IUB). After alignment of the sequences using the Clustal W program, "percent identity" can be obtained by looking up the "sequence distance" table in the same program. Unless otherwise specified, sequence identity / similarity values given herein refer to values obtained using GAP version 10 (GCG, Accelrys, San Diego, Calif.) with the following parameters: nucleotides; Sequence % identity and similarity use a gap generation penalty weight of 50, gap length extension penalty weight of 3 and the nwsgapdna.cmp scoring matrix; amino acid sequence % identity and similarity use a gap generation penalty weight. 8, using a gap length extension penalty of 2 and the BLOSUM62 scoring matrix (Henikoff and Henikoff, (1989) Proc. Natl. Acad. Sci. USA 89:10915). GAP uses the algorithm of Needleman and Wunsch, (1970) J Mol Biol 48:443-53 to find alignments over two sequences that maximize the number of matches and minimize the number of gaps. GAP considers all possible alignments and gap positions and uses gap creation and gap extension penalties in units of matched bases to produce the alignment with the maximum number of matched bases and minimum gaps. "BLAST" is a search algorithm used to find similar regions of biological sequences provided by the National Center for Biotechnology Information (NCBI). This program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches to identify sequences sufficiently similar to the query sequence such that the similarity is not expected to occur randomly. . BLAST reports the identified sequences and their local alignments to the query sequence. Many levels of sequence identity are useful in identifying polypeptides from other species or that have been naturally or synthetically modified, such polypeptides having the same or similar function or activity. This will be well understood by those skilled in the art. Useful examples of percent identity include 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% or any percentage from 50% to 100%. include, but are not limited to. Indeed any amino acid identity between 50% and 100%, e.g. 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78% , 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95 %, 96%, 97%, 98% or 99% identity can be useful in describing the present disclosure.
[0273] Polynucleotide and polypeptide sequences, variants thereof and structural relationships of these sequences are referred to herein by the terms "homology," "homologous," "substantially identical," Can be described by "substantially similar" and "substantially correspond". They refer to polypeptide or nucleic acid sequences in which changes in one or more amino acid or nucleotide bases do not affect the function of the molecule, such as its ability to mediate expression of a gene or its ability to produce a particular phenotype. These terms also refer to modifications of nucleic acid sequences in which the functional properties of the resulting nucleic acid are not substantially altered as compared to the initial, unmodified nucleic acid. These modifications include deletions, substitutions and / or insertions of one or more nucleotides in the nucleic acid fragment. Substantially similar nucleic acid sequences encompass sequences exemplified herein or They can be defined by their ability to hybridize to any portion of the nucleotide sequence and are functionally equivalent to any of the nucleic acid sequences disclosed herein. Stringency conditions are adjusted to convert fragments with moderate similarity, such as homologous sequences from distantly related organisms, to fragments with high similarity, such as genes duplicating functional enzymes from closely related organisms. can be screened. Post-hybridization washes determine stringency conditions.
[0274] A "centimorgan" (cM) or "map unit" is the distance between two polynucleotide sequences, binding genes, markers, target sites, loci, or any pair thereof, where 1% is recombinant. A centimorgan is therefore equivalent to a distance equal to the average recombination frequency of 1% between two linked genes, markers, target sites, loci or any pair thereof.
[0275] An "isolated" or "purified" nucleic acid molecule, polynucleotide, polypeptide or protein, or biologically active portion thereof, refers to the polynucleotide or It is substantially or essentially free of components that co-occur with or interact with the protein. Thus, an isolated or purified polynucleotide or protein will be substantially free of other cellular material and culture medium when produced by recombinant techniques, or chemical precursors when chemically synthesized. Virtually free of body and other chemicals. Optimally, an "isolated" polynucleotide (optimally, a protein-encoding sequence) will be defined in the genomic DNA of the organism from which it is derived, sequences that naturally flank it ( ie sequences located at the 5' and 3' ends of the polynucleotide). For example, in various embodiments, an isolated polynucleotide is about 5 kb, 4 kb, 3 kb, 2 kb, 1 kb, 0.5 kb or 0.1 kb that naturally flanks the polynucleotide in the genomic DNA of the cell from which the polynucleotide was derived. It may contain nucleotide sequences of less than kb. Isolated polynucleotides can be purified from the cells in which they naturally occur. Isolated polynucleotides can be obtained using conventional nucleic acid purification methods known to those of skill in the art. The term also includes recombinant and chemically synthesized polynucleotides.
[0276] The term "fragment" refers to a contiguous set of nucleotides or amino acids. In one embodiment, the fragment is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more than 20 consecutive is a nucleotide with In one embodiment, the fragment is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more than 20 consecutive It is an amino acid that Fragments may or may not exhibit the function of sequences sharing some percent identity over the entire length of the fragment.
[0277] The terms "functionally equivalent fragment" and "functionally equivalent fragment" are used interchangeably herein. These terms refer to isolated nucleic acid fragments or polypeptide portions or subsequences that exhibit the same activity or function as the longer sequence from which they are derived. In one example, the fragment retains the ability to alter gene expression or produce a particular phenotype, regardless of whether the fragment encodes an active protein. For example, fragments can be used to design genes that give rise to desired phenotypes in modified plants. A gene is designed to be used repressively by binding its nucleic acid fragment, whether or not it encodes an active enzyme, to a plant promoter sequence in a sense or antisense orientation. be able to.
[0278] A "gene" refers to a functional molecule such as, but not limited to, a specific protein, including, for example, regulatory sequences preceding (5' non-coding sequences) and following (3' non-coding sequences) the coding sequence. Included are expressed nucleic acid fragments. "Native gene" refers to a gene as found in its natural endogenous location with its own regulatory sequences.
[0279] The term "endogenous" refers to sequences or other molecules that are naturally occurring in a cell or organism. In one aspect, an endogenous polynucleotide is normally found in the genome of the cell, ie is not heterologous.
[0280] An "allele" is one of several alternative forms of a gene occupying a given locus on a chromosome. If all alleles present at a given genetic locus on a chromosome are the same, the plant is homozygous at that locus. If the alleles present at a given genetic locus on a chromosome are different, the plant is heterozygous at that locus.
[0281] A "coding sequence" refers to a polynucleotide sequence that encodes a specific amino acid sequence. A "regulatory sequence" refers to a nucleotide sequence located upstream (5'-noncoding sequence), within a coding sequence, or downstream (3'-noncoding sequence) of a coding sequence, which is responsible for transcription of the associated coding sequence. , affect RNA processing or stability or translation. Regulatory sequences include, but are not limited to, promoters, translation leader sequences, 5' untranslated sequences, 3' untranslated sequences, introns, polyadenylation target sequences, RNA processing sites, effector binding sites and stem-loop structures. .
[0282] A "mutant gene" is a gene that has been altered by human intervention. Such a "mutant gene" has a sequence that differs from that of the corresponding non-mutant gene by the addition, deletion or substitution of at least one nucleotide. In certain embodiments of the disclosure, the mutated gene comprises changes resulting from the guide polynucleotide / Cas endonuclease system as disclosed herein. A mutant plant is a plant containing a mutant gene.
[0283] As used herein, a "targeted mutation" is a mutation within a target gene using any method known to those of skill in the art, including methods involving the inducible Cas endonuclease system disclosed herein. Mutations in genes (called target genes), including native genes, are made by altering the target sequence.
[0284] The terms "knockout", "genetic knockout" and "genetic knockout" are used interchangeably herein. Knockout refers to a cellular DNA sequence that has been partially or completely disabled by targeting with a Cas protein, e.g. promoter).
[0285] The terms "knock-in", "gene knock-in", "gene insertion" and "genetic knock-in" are used interchangeably herein. Knock-in refers to the replacement or insertion of a DNA sequence at a specific DNA sequence in a cell by targeting with Cas proteins (eg by homologous recombination (HR), also using suitable donor DNA polynucleotides). Examples of knock-ins are the specific insertion of heterologous amino acid coding sequences in the coding regions of genes or the specific insertion of transcriptional regulatory elements at genetic loci.
[0286] "Domain" means a contiguous stretch of nucleotides (which can be RNA, DNA and / or combined RNA-DNA sequences) or amino acids.
[0287] The term "conserved domain" or "motif" refers to a series of polynucleotides or amino acids that are conserved at specific positions along aligned sequences of evolutionarily related proteins. Amino acids at other positions can vary between homologous proteins, while amino acids that are highly conserved at a particular position represent amino acids that are essential for protein structure, stability or activity. Identifiers or "signatures" that determine whether a protein with a newly determined sequence belongs to a previously identified protein family, as they are identified by the high degree of conservation of aligned sequences of families of protein homologues can be used as
[0288] A "codon modified gene" or "codon preference gene" or "codon optimized gene" is a gene with codon usage designed to mimic the preferred codon usage of a host cell.
[0289] An "optimized" polynucleotide is a sequence that has been optimized to improve expression in a particular heterologous host cell.
[0290] A "plant-optimized nucleotide sequence" is a nucleotide sequence optimized for improved expression in plants, in particular for increased expression in plants. Plant-optimized nucleotide sequences include codon-optimized genes. A plant-optimized nucleotide sequence is obtained by modifying a nucleotide sequence that encodes a protein, such as the Cas endonuclease disclosed herein, using one or more plant-preferred codons for improved expression, e.g. Can be synthesized. See, eg, Campbell and Gowri (1990) Plant Physiol. 92:1-11 for a discussion of host-preferred codon usage.
[0291] A "promoter" is a region of DNA involved in the recognition and binding of RNA polymerase and other proteins that initiate transcription. The promoter sequence consists of proximal and more distal upstream elements, the latter elements often referred to as enhancers. An "enhancer" is a DNA sequence capable of stimulating promoter activity, and may be a promoter-specific element or a heterologous element inserted to enhance the level or tissue specificity of a promoter. Promoters may be derived in their entirety from a native gene, or be composed of different elements derived from different promoters found in nature, and / or comprise synthetic DNA segments. It is understood by those skilled in the art that different promoters can direct gene expression in different tissue or cell types, or at different developmental stages, or in response to different environmental conditions. It is further recognized that some variations of DNA fragments may have identical promoter activity, since in most cases the exact boundaries of regulatory sequences have not been completely defined.
[0292] Promoters that cause the most gene expression in most cell types are commonly referred to as "constitutive promoters." The term "inducible promoter" is used in response to the presence of an endogenous or exogenous stimulus, e.g. by a chemical compound (chemical inducer), or in response to environmental, hormonal, chemical and / or developmental signals. Refers to a promoter that selectively expresses a sequence or functional RNA. Inducible or regulated promoters include, for example, light, heat, stress, flooding or drought, salt stress, osmotic stress, plant hormones, wound or ethanol, abscisic acid (ABA), jasmonic acid, salicylic acid or safeners. Promoters that are induced or regulated by chemical substances are included.
[0293] "Translation leader sequence" refers to the polynucleotide sequence between the promoter and coding sequences of a gene. A translation leader sequence is present upstream of the translation initiation sequence of the mRNA. A translation leader sequence may influence the processing of the primary transcript into mRNA, mRNA stability or translation efficiency. Examples of translation leader sequences have been described (see, eg, Turner and Foster, (1995) Mol Biotechnol 3:225-236).
[0294] A "3' non-coding sequence," "transcription terminator," or "termination sequence" refers to a DNA sequence located downstream of a coding sequence, which includes polyadenylation recognition sequences and regulatory sequences capable of affecting mRNA processing or expression of a gene. Contains other sequences that encode signals. Polyadenylation signals are usually characterized by affecting the addition of a polyadenylate stretch to the 3' end of the pre-mRNA.

[0297] The term "operably linked" refers to the association of nucleic acid sequences on a single nucleic acid fragment such that the function of one is regulated by the other. For example, a promoter is operably linked to a coding sequence (ie, the coding sequence is under the transcriptional control of the promoter) if the expression of the coding sequence can be controlled. Coding sequences can be operably linked to regulatory sequences in sense or antisense orientation. In another example, the complementary RNA region can be operably linked, directly or indirectly, to the 5' end of the target mRNA or the 3' end of the target mRNA or within the target mRNA, or The region is the 5' end of the target mRNA and its complement is the 3' end of the target mRNA.

Such constructs can be used by themselves or with vectors. When a vector is used, the choice of vector depends on the method used to introduce the vector into the host cell, as is well known to those skilled in the art. For example, plasmid vectors can be used. Those skilled in the art are familiar with the genetic elements that must be present on the vector in order to successfully transform, select and propagate host cells. One skilled in the art will recognize that different independent transformation events result in different expression levels and patterns (Jones et al., (1985) EMBO J 4:2411-2418; De Almeida et al., (1989) Mol Gen Genetics 218: 78-86), thus it will also be appreciated that usually multiple events are screened to obtain a strain exhibiting the desired expression level and pattern. Such screening may include Southern analysis of DNA, Northern analysis of mRNA expression, PCR, real-time quantitative PCR (qPCR), reverse transcription PCR (RT-PCR), immunoblotting of protein expression, enzymatic or activity analysis and / or expression.

It may refer to a sequence that has been substantially altered from its natural form by human intervention. For example, a promoter operably linked to a heterologous polynucleotide may be from a species different from the species from which the polynucleotide was derived, or from the same / similar species if one or both Either the morphology and / or the genomic locus has been substantially altered, or the promoter is not the native promoter of the polynucleotide to which it is operably linked. Alternatively, one or more of the regulatory regions and / or polynucleotides presented herein may be entirely synthetic. In another example, a target polynucleotide for cleavage by a Cas endonuclease can be from a different organism than the Cas endonuclease. In another example, the Cas endonuclease and guide RNA can be introduced into the target polynucleotide along with additional polynucleotides that act as templates or donors for insertion into the target polynucleotide. Here the additional polynucleotide is heterologous to the target polynucleotide and / or the Cas endonuclease.

Thus, the phenotypic differences between the two groups may be due only to treatments and not to any peculiarities of the plant's endogenous genetic makeup.

[0351] Classification of CRISPR-Cas systems CRISPR-Cas systems have been classified according to component sequence and structural analysis. Multiple, including class 1 systems with multi-subunit effector complexes (including types I, III and IV) and class 2 systems with single protein effectors (including types II, V and VI) A CRISPR / Cas system has been described (Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15; Zetsche et al., 2015, Cell 163, 1-13; Shmakov et al., 2015, Molecular Cell 60, 1-13; Haft et al., 2005, Computational Biology, PLoS Comput Biol 1(6):e60; and Koonin et al. 2017, Curr Opinion Microbiology 37:67-78).
[0352] A CRISPR-Cas system comprises at least a CRISPR RNA (crRNA) molecule and at least one CRISPR-associated (Cas) protein to form a crRNA ribonucleoprotein (crRNP) effector complex. The CRISPR-Cas locus contains an array of identical repeats interspersed with DNA targeting spacers that encode crRNA components and an operon-like unit of the cas gene that encodes the Cas protein components. The resulting ribonucleoprotein complex recognizes polynucleotides in a sequence-specific manner (Jore et al., Nature Structural & Molecular Biology 18, 529-536 (2011)). crRNAs sequence-specifically bind effectors (proteins or complexes) to double-stranded DNA sequences by base-pairing with complementary DNA strands while displacing the non-complementary strands, forming a so-called R-loop. It functions as a guide RNA that allows (Jore et al., 2011. Nature Structural & Molecular Biology 18, 529-536).
[0353] RNA transcripts (pre-crRNA) of CRISPR loci are cleaved specifically at repeat sequences by CRISPR-associated (Cas) endoribonucleases in type I and type III systems or RNase III in type II systems. The number of CRISPR-associated genes at a given CRISPR locus can vary by species.
[0354] Different cas genes encoding proteins with different domains exist in different CRISPR systems. The cas operon contains genes encoding one or more effector endonucleases and other Cas proteins. Protein subunits include Makarova et al.2011, Nat Rev Microbiol.2011 9(6):467-477; Makarova et al.2015, Nature Reviews Microbiology Vol.13:1-15; and Koonin et al.2017, Current Opinion Microbiology 37:67-78). Types of domains include those involved in expression (pre-crRNA processing, e.g., Cas 6 or RNase III), those involved in buffering (effector modules for crRNA and target binding, and domains for target cleavage). ), those involved in adaptation (spacer insertion, eg Cas1 or Cas2) and those involved in assistance (regulatory or helper or unknown function). Some domains may serve more than one purpose, for example Cas9, among others, contains a domain for endonuclease function and a domain for targeted cleavage.
[0355] The Cas endonuclease is induced by a single CRISPR RNA (crRNA) through direct RNA-DNA base pairing and recognizes DNA target sites adjacent to the protospacer adjacent motif (PAM) (Jore, M.M. et al. al., 2011, Nat. Struct. Mol. Biol. 18:529-536, Westra, E.R. et al., 2012, Molecular Cell 46:595-605 and Sinkunas, T. et al., 2013, EMBO J.32 :385-394).
[0356] Class I CRISPR-Cas system Class I CRISPR-Cas systems include types I, III and IV. A unique feature of Class I systems is the presence of effector endonuclease complexes instead of single proteins. The cascade complex contains an RNA recognition motif (RRM) and a nucleic acid-binding domain that is the corefold of the diverse RAMP (repeat-related mysterious protein) protein superfamily (Makarova et al. 2013, Biochem Soc Trans 41, 1392-1400; Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15). RAMP protein subunits include Cas5 and Cas7 (which comprise the backbone of the crRNA-effector complex, where the Cas5 subunit binds to the 5' handle of crRNA and interacts with the large subunit), and many contains Cas6, which is loosely associated with effector complexes and generally functions as a repeat-specific RNase in pre-crRNA processing (Charpentier et al., FEMS Microbiol Rev 2015,39:428-441; Niewoehner et al., RNA 2016, 22:318-329).
[0357] The type I CRISPR-Cas system contains a complex of effector proteins called the cascade (CRISPR-associated complexes for antiviral defense), including at least Cas5 and Cas7. Effector complexes work together with a single CRISPR RNA (crRNA) and Cas3 to defend against invading viral DNA (Brouns, S.J.J. et al. Science 321:960-964; Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15). The type I CRISPR-Cas locus contains a metal-dependent nuclease with a single-stranded DNA (ssDNA)-stimulated superfamily 2 helicase that has demonstrated the ability to unwind double-stranded DNA (dsDNA) and RNA-DNA duplexes. contains the signature gene cas3 (or variant cas3′ or cas3″) encoding (Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15). recruits into DNA complexes to cleave and degrade DNA targets (Westra, E.R. et al. (2012) Molecular Cell 46:595-605; Sinkunas, T. et al. (2011) EMBO J.30:1335- 1342 and Sinkunas, T. et al. (2013) EMBO J.32:385-394) In some type I systems, Cas6 may be the active endonuclease involved in crRNA processing, while Cas5 and Cas7 , functions as a non-catalytic RNA-binding protein, whereas in the type I-C system, crRNA processing can be catalyzed by Cas5 (Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15). are divided into seven subtypes (Makarova et al. 2011, Nat Rev Microbiol. 2011 9(6):467-477; Koonin et al. 2017, Curr Opinion Microbiology 37:67-78), at least protein subunits. A modified type I CRISPR-associated complex (cascade) for adaptive antiviral defense comprising Cas7, Cas5 and Cas6, one of these subunits synthetically fused to the Cas3 endonuclease or the modified restriction endonuclease FokI. (International Publication No. 2013098244 pamphlet published on July 4, 2013).
[0358] The type III CRISPR-Cas system, which contains multiple cas7 genes, targets ssRNA or ssDNA and functions as either an RNase and a target RNA-activating DNA nuclease (Tamulaitis et al., Trends in Microbiology 25(10)49- 61, 2017). Csm (type III-A) and Cmr (type III-B) complexes function as RNA-activated single-stranded (ss) DNases that couple target RNA binding / cleavage with ssDNA degradation. Upon infection with foreign DNA, CRISPR RNA (crRNA)-induced binding of the Csm or Cmr complex to new transcripts recruits Cas10 DNase to the actively transcribed phage DNA, resulting in transcription of the transcript. and phage DNA are both degraded, but host DNA is not. The Cas10 HD domain is responsible for ssDNase activity and the Csm3 / Cmr4 subunits are responsible for the endoribonuclease activity of the Csm / Cmr complex. The 3' flanking sequence of target RNA is critical for the ssDNase activity of Csm / Cmr: base pairing with the 5' handle of crRNA protects host DNA from degradation.
[0359] Type IV systems contain typical type I cas5 and cas7 domains in addition to cas8-like domains, but may lack the CRISPR arrays characteristic of most other CRISPR-Cas systems.
[0360] Class II CRISPR-Cas system Class II CRISPR-Cas systems include types II, V and VI. A unique feature of class II systems is the presence of a single Cas effector protein instead of effector complexes. Type II and V Cas proteins contain a RuvC endonuclease domain that adopts the RNase H-fold.
[0361] Type II CRISPR / Cas systems use crRNA and tracrRNA (trans-activating CRISPR RNA) to direct the Cas endonuclease to a DNA target. The crRNA base-pairs with a spacer region complementary to one strand of the double-stranded DNA target and tracrRNA (trans-activating CRISPR RNA) to form an RNA duplex that allows the Cas endonuclease to cleave the DNA target. , including regions that leave blunt ends. Spacers are obtained by a poorly understood process involving the Cas1 and Cas2 proteins. Type II CRISPR / Cas loci generally contain the cas1 and cas2 genes in addition to the cas9 gene (Chylinski et al., 2013, RNA Biology 10:726-737; Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15). Type II CRISR-Cas loci can encode tracrRNAs that are partially complementary to repeats in each CRISPR array and can include other proteins such as Csn1 and Csn2. The presence of cas9 in the vicinity of cas1 and cas2 genes is characteristic of type II loci (Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15).
[0362] The type V CRISPR / Cas system contains a single Cas endonuclease, including Cpf1 (Cas12) (Koonin et al., Curr Opinion Microbiology 37:67-78, 2017), which, unlike Cas9, is responsible for targeted cleavage. It is an active RNA-guided endonuclease that does not necessarily require additional trans-activating CRISPR (tracr) RNA for activation.
[0363] The type VI CRISPR-Cas system has two HEPN (higher eukaryotic and prokaryotic nucleotide-binding) domains, but no HNH domain, nor a RuvC domain, and contains a cas13 gene that is independent of tracrRNA activity. Most of the HEPN domains contain conserved motifs that constitute metal-independent endo-RNase active sites (Anantharam et al., Biol Direct 8:15, 2013). Because of this feature, the Type VI system is thought to act on RNA targets instead of DNA targets common to other CRISPR-Cas systems.
[0364] Novel CRISPR-Cas system A novel CRISPR-Cas system, its components and methods of using said components are disclosed herein. This system contains a novel Cas effector protein, Cas-beta.
[0365] The novel CRISPR-Cas system components described herein are derived from or modified from one or more subunits from different Cas systems, two or more different bacterial or archaeal prokaryotes It may contain subunits and / or synthetic or engineered components.
[0366] Described herein are newly identified CRISPR-Cas systems that include novel sequences of cas genes. Further novel cas genes and proteins are described.
[0367] One distinguishing feature of the novel Cas-beta system is the locus structure as described in FIG. The order of the polynucleotides on the complementary strand is as follows: an unclassified cas gene that shares low sequence identity with the cas-beta gene, cas1 gene, cas2 gene and cas4. The unclassified cas gene was followed by a CRISPR array containing 37 repeats of 37 nucleotide sequences, 33 of which were identical, 3 of which were 97.3% identical, and one at the end. exists with 78.4% identity. The spacer polynucleotide between each array repeat is 35 or 36 nucleotides long.
[0368] CRISPR-Cas system components Cas-protein A large number of proteins are involved in the CRISPR cas operon, including those involved in adaptation (spacer insertion), interference (effector module target binding, target nicking or cleavage - e.g., endonuclease activity), expression (pre-crRNA processing), regulation, and others. can be coded to
[0369] Two proteins, Cas1 and Cas2, are conserved among many CRISPR systems (described, for example, in Koonin et al., Curr Opinion Microbiology 37:67-78, 2017). Cas1 is a metal-dependent DNA-specific endonuclease that produces double-stranded DNA fragments. In some systems, Cas1 forms a stable complex with Cas2, which is essential for spacer acquisition and insertion for the CRISPR system (Nunez et al., Nature Str Mol Biol 21:528-534, 2014 ).
[0370] Many other proteins, including Cas4, which may have similarities to the RecB nuclease, have been identified in various systems and are thought to play a role in capturing new viral DNA sequences for incorporation into CRISPR arrays. (Zhang et al., PLOS One 7(10):e47232, 2012).
[0371] Some proteins may encompass multiple functions. For example, the class 2 type II system signature protein Cas9 has been demonstrated to be involved in pre-crRNA processing, target binding and target cleavage.
[0372] The novel Cas-beta proteins disclosed herein include effector proteins (endonucleases) and adaptation proteins.
[0373] Cas endonuclease and effector Endonucleases are enzymes that cleave the phosphodiester bonds of polynucleotide chains and include restriction endonucleases that cleave DNA at specific sites without damaging the bases. Examples of endonucleases include restriction endonucleases, meganucleases, TAL effector nucleases (TALENs), zinc finger nucleases and Cas (CRISPR-related) effector endonucleases.
[0374] The Cas endonuclease, either as a single effector protein or in an effector complex with other components, unwinds the DNA duplex at the target sequence and the polynucleotide complexed with the Cas effector protein (hereinafter Optionally, at least one DNA strand is cleaved when mediated by recognition of the target sequence by, but not limited to, crRNA or guide RNA. Such recognition and cleavage of a target sequence by a Cas endonuclease generally requires that the correct protospacer adjacent motif (PAM) is located at or at the 3' end of the DNA target sequence. Occurs when adjacent. Alternatively, the Cas endonucleases herein may lack DNA cleaving or nicking activity when complexed with suitable RNA components, but still be able to specifically bind DNA target sequences. (See also U.S. Patent Application Publication No. 2015 / 0082478, published March 19, 2015 and U.S. Patent Application Publication No. 2015 / 0059010, published February 26, 2015).
[0375] Cas endonucleases can occur as individual effectors (class 2 CRISPR systems) or as part of larger effector complexes (class I CRISPR systems).
[0376] Cas endonucleases that have been described include, for example, Cas3 (characteristic of class 1 type I systems), Cas9 (characteristic of class 2 type II systems) and Cas12 (Cpf1) (characteristic of class 2 type V systems). but not limited to these.
[0377] Cas3 (and its variants Cas3' and Cas3'') functions as a single-stranded DNA nuclease (HD domain) and an ATP-dependent helicase. Functional activity can be obtained by abolishing ATPase-dependent helicase activity (by deletion, knockout of the Cas3-helicase domain, or by mutagenesis of key residues, or as previously described (Sinkunas, T, et al., 2013, EMBO J.32:385-394) by abolishing the cleavage readiness cascade involving the modified Cas3 endonuclease by assembling the reaction in the absence of ATP as can be converted to a nickase (because the HD domain is still functional) Disabling HD endonuclease activity includes, but is not limited to, mutagenesis of key residues in the HD domain, known in the art. and can convert a cleavage-ready cascade comprising a modified Cas3 endonuclease into a helicase.The abrogation of both Cas helicase and Cas3 HD endonuclease activity includes, but is not limited to: A cleavage-ready cascade comprising a modified Cas3 endonuclease, which can be achieved by methods known in the art, such as mutagenesis of key residues in both the helicase and HD domains, binds to the target sequence. It can be converted into protein.
[0378] Cas9 (previously called Cas5, Csn1 or Csx12) complexes with cr and tracr nucleotides or a single guide polynucleotide to specifically recognize and cleave all or part of a DNA target sequence. is a Cas endonuclease that Cas9 recognizes 3'GC-rich PAM sequences in target dsDNA. The Cas9 protein contains a RuvC nuclease with HNH (H-N-H) nucleases flanking the RuvC-II domain. The RuvC nuclease and the HNH nuclease can each cleave a single strand of DNA at the target sequence (cooperative action of both domains results in DNA double-strand breaks, while activity of one domain leads to nicking. bring). In general, the RuvC domain comprises subdomains I, II and III, with domain I located near the N-terminus of Cas9 and subdomains II and III located in the middle of the protein and flanked by HNH domains. (Hsu et al, Cell 157:1262-1278). The Cas9 endonuclease is typically derived from the type II CRISPR system, which includes a DNA cleavage system that utilizes the Cas9 endonuclease complexed with at least one polynucleotide component. For example, Cas9 can be complexed with CRISPR RNA (crRNA) and transactivating CRISPR RNA (tracrRNA). In another example, Cas9 can exist in a complex with a single guide RNA (Makarova et al. 2015, Nature Reviews Microbiology Vol. 13:1-15).
[0379] Cas12 (previously called Cpf1 and variants c2c1, c2c3, CasX and CasY) contained the RuvC nuclease domain and generated a staggered 5' overhang on the dsDNA target. Some variants do not require tracrRNA, unlike Cas9 functionality. Cas12 and its variants recognize 5'AT-rich PAM sequences on target dsDNA. An insertion domain called Nuc of the Cas12a protein has been demonstrated to be involved in targeted strand cleavage (Yamano et al., Cell 2016,165:949-962). Further mutational studies in other Cas12 proteins demonstrated that the Nuc domain contributes to induction and target binding along with the RuvC domain involved in cleavage (Swarts et al., Mol Cell 2017, 66:221-233 e224). .
[0380] Cas endonucleases and effector proteins can be used for targeted genome editing (by single and multiple double-strand breaks and nicks) and targeted genome regulation (by attaching epigenetic effector domains to Cas proteins or sgRNAs). can. Cas endonucleases can also be engineered to function as RNA-guided recombinases and through RNA tethers can serve as scaffolds for the assembly of multiple protein and nucleic acid complexes (Mali et al., 2013, Nature Methods Vol. 10: 957-963).
[0381] Cas-beta endonuclease A Cas-beta endonuclease is defined as a functional RNA-guided PAM-dependent dsDNA cleavage protein of less than 900 amino acids and contains at least one of the motifs listed in Table 1B.
[0382] The RuvC domain has been demonstrated in the literature to contain endonuclease functionality. Cas-beta endonucleases can be isolated or identified from genetic loci comprising arrays containing cas-beta genes and multiple repeats that encode effector proteins. In some embodiments, the cas-beta locus may further comprise part or all of the cas1 gene, the cas2 gene and / or the cas4 gene.
[0383] A zinc finger motif is a domain that coordinates one or more zinc ions, usually through cysteine and histidine side chains, to stabilize their fold. Zinc fingers are named for the pattern of cysteine and histidine residues coordinating the zinc ion (e.g., C4 means the zinc ion is coordinated to four cysteine residues, C3H is the zinc meaning that the ion is coordinated to three cysteine residues and one histidine residue).
[0384] Cas-beta endonucleases are RNA-guided endonucleases that can bind and cleave double-stranded DNA targets that contain (1) sequences that share homology with the nucleotide sequence of the guide RNA and (2) PAM sequences. is. In some aspects, the PAM is T-rich. In some aspects, the PAM is C-rich.
[0385] A Cas-beta endonuclease functions as a double-strand break inducer and can be a nickase or a single-strand break inducer. In some embodiments, a catalytically inactive Cas-beta endonuclease can be used to target or recruit to a target DNA sequence, but does not induce cleavage. In some embodiments, a catalytically inactive Cas-beta protein can be used with a functional endonuclease that cleaves the target sequence. In some embodiments, a catalytically inactive Cas-beta protein can be combined with a base-editing molecule such as a deaminase. In some aspects, the deaminase can be cytidine deaminase. In some aspects, the deaminase can be an adenine deaminase. In some embodiments, the deaminase can be ADAR-2.
[0386] The Cas-beta endonuclease is at least 50, 50-100, at least 100, 100-150 of any of SEQ ID NO: 13, 14, 15 or 57, or a functional fragment or functional variant thereof that retains at least a portion of the activity , at least 150, 150-200, at least 200, 200-250, at least 250, 250-300, at least 300, 300-350, at least 350, 350-400, at least 400, 400-450, at least 500 or more than 500 continuously at least 50%, 50%-55%, at least 55%, 55%-60%, at least 60%, 60%-65%, at least 65%, 65%-70%, at least 70%, 70% ~75%, at least 75%, 75%~80%, at least 80%, 80%~85%, at least 85%, 85%~90%, at least 90%, at least 90%~95%, at least 95%, 95 %~96%, at least 96%, 96%~97%, at least 97%, 97%~98%, at least 98%, 98%~99%, at least 99%, 99%~100% or 100% sequence identity It is further defined as a sex-sharing RNA-induced double-stranded DNA-breaking protein. A "functional fragment" of a Cas-beta endonuclease is capable of recognizing or binding or nicking a single strand of a double-stranded polynucleotide or cleaving both strands of a double-stranded polynucleotide. Possess abilities or any combination thereof.
[0387] Cas-beta endonucleases contain one or more motifs listed in Table 1B.
[0388] The Cas-beta endonuclease is any of the sequences in the sequence listing at least 50, 50-100, at least 100, 100-150, at least 150, 150-200, at least 200, 200-250, at least 250, 250-300, at least 300, 300-350, at least 350, 350-400, at least 400, 400-450, at least 500, 500-550, at least 600, 600-650, at least 650, 650-700, at least 700, 700-750, at least 750, 750-800, at least 800, 800-850, at least 850, 850-900, at least 900, 900-950, at least 950, 950-1000, at least 1000 or more than 1000 contiguous nucleotides and at least 50%, 50 %~55%, at least 55%, 55%~60%, at least 60%, 60%~65%, at least 65%, 65%~70%, at least 70%, 70%~75%, at least 75%, 75 %~80%, at least 80%, 80%~85%, at least 85%, 85%~90%, at least 90%, 90%~95%, at least 95%, 95%~96%, at least 96%, 96 %-97%, at least 97%, 97%-98%, at least 98%, 98%-99%, at least 99%, 99%-100% or 100% sequence identity. .
[0389] Cas endonucleases, effector proteins or functional fragments thereof for use in the disclosed methods may be from natural sources or genetically modified host cells which have been modified to express nucleic acid sequences encoding the proteins. It can be isolated from alternative sources. Alternatively, the Cas protein can be produced using cell-free protein expression systems or produced synthetically. Effector Cas nucleases can be isolated and introduced into heterologous cells, or can be modified from their native form to exhibit a different type or magnitude of activity than their natural source. Such modifications include, but are not limited to fragments, variants, substitutions, deletions and insertions.
[0390] Fragments and variants of Cas endonuclease and Cas effector proteins can be obtained by methods such as site-directed mutagenesis and synthetic construction. Methods of measuring endonuclease activity are well known in the art, e.g. No. 2016186953 and WO2016186946 published Nov. 24, 2016, but are not limited thereto.
[0391] Cas endonucleases can include modified forms of Cas polypeptides. Modified forms of Cas polypeptides can include amino acid changes (eg, deletions, insertions or substitutions) that reduce the naturally occurring nuclease activity of the Cas protein. For example, in some instances, a modified form of a Cas protein is less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, less than 5%, or less than 1% of the corresponding wild-type Cas polypeptide. (U.S. Patent Application Publication No. 20140068797, published Mar. 6, 2014). In some instances, modified forms of Cas polypeptides have substantially no nuclease activity and are referred to as catalytically "inactivated Cas" or "inactivated cas(dCas)." Inactivated Cas / Deactivated Cas contains deactivated Cas endonuclease (dCas). Catalytically inactive Cas effector proteins can be fused to heterologous sequences to induce or modify activity.

[0413] Protospacer Adjacent Motif (PAM) A "protospacer adjacent motif" (PAM) herein refers to a short nucleotide sequence that flanks a target sequence (protospacer) that is recognized (targeted) by the guide polynucleotide / Cas endonuclease system. A Cas endonuclease cannot correctly recognize a target DNA sequence without a PAM sequence following the target DNA sequence. The PAM sequence and length herein may vary depending on the Cas protein or Cas protein complex used. PAM sequences can be of any length, but are generally 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18 , 19 or 20 nucleotides long.
[0414] "Randomized PAM" and "randomized protospacer-adjacent motif" are used interchangeably herein and refer to the target sequence (protospacer) recognized (targeted) by the guide polynucleotide / Cas endonuclease system. A random DNA sequence that flanks a Randomized PAM sequences can be of any length, but are generally 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 , 18, 19 or 20 nucleotides long.

[0415] Guide polynucleotide / Cas endonuclease complex The guide polynucleotide / Cas endonuclease complexes described herein are capable of recognizing, binding to, and optionally nicking, unwinding or cleaving all or part of a target sequence.
[0416] A guide polynucleotide / Cas endonuclease complex capable of cleaving both strands of a DNA target sequence is typically a Cas protein that has all of the endonuclease domains in a functional state (e.g., the wild-type endonuclease domain or each variants thereof that retain the activity of part or all of the endonuclease domain). Thus, a wild-type Cas protein (e.g., a Cas protein disclosed herein) or a variant thereof that retains the activity of part or all of each endonuclease domain of the Cas protein may be used in both DNA target sequences. It is a good example of a Cas protein that can cut strands.
[0417] A guide polynucleotide / Cas endonuclease complex capable of cleaving a single strand of a DNA target sequence can be characterized herein as having nickase activity (eg, partial cleavage capability). A Cas nickase typically contains a monofunctional endonuclease domain that allows Cas to cleave (ie, nick) only a single strand of a DNA target sequence. For example, a Cas9 nickase can include (i) a mutated, dysfunctional RuvC domain, and (ii) a functional HNH domain (eg, a wild-type HNH domain). As another example, a Cas9 nickase can include (i) a functional RuvC domain (eg, a wild-type RuvC domain) and (ii) a mutated, dysfunctional HNH domain. A non-limiting example of a Cas9 nickase suitable for use herein is disclosed in US Patent Application Publication No. 20140189896, published Jul. 3, 2014. A pair of Cas nickases can be used to increase the specificity of DNA targeting. Generally, this provides two Cas nickases that target DNA sequences on opposite strands within that region and nick in close proximity for desired targeting by combining RNA components with different guide sequences. can be implemented by Such breaks near each DNA strand cause double-strand breaks (i.e., DSBs with single-stranded overhangs), which then result in incomplete repair leading to non-homologous end-joining NHEJ (mutations). easy) or as a substrate for homologous recombination HR. Each nick in these embodiments is, for example, at least about 5, 5-10, at least 10, 10-15, at least 15, 15-20, at least 20, 20-30, at least 30, 30-40, at least 40, 40 to 50, at least 50, 50 to 60, at least 60, 60 to 70, at least 70, 70 to 80, at least 80, 80 to 90, at least 90, 90 to 100, or 100 or more (or any integer from 5 to 100 ), can be separated from each other. One or two Cas nickase proteins herein can be used in a Cas nickase pair. For example, a Cas9 nickase (ie, Cas9 HNH+ / RuvC−) that has a mutated RuvC domain but a functional HNH domain can be used (eg, Streptococcus pyogenes Cas9 HNH+ / RuvC−). Each Cas9 nickase (e.g., Cas9 HNH+ / RuvC-) is brought close together (maximum 100 base pairs apart) can be directed to specific DNA sites.
[0418] The guide polynucleotide / Cas endonuclease complex in certain embodiments can bind to a DNA target site sequence, but does not cleave any strand at the target site sequence. Such complexes may contain a Cas protein whose entire nuclease domain is mutated and dysfunctional. For example, a Cas9 protein that can bind to a DNA target site sequence but does not cleave any strand at the target site sequence can contain both a mutated, dysfunctional RuvC domain and a mutated, dysfunctional HNH domain. A Cas protein herein that binds to, but does not cleave, a target DNA sequence can be used to modulate gene expression, e.g., where the Cas protein is a transcription factor (or part thereof) (eg, a repressor or activator, such as any of those disclosed herein).

Ther. Nucleic Acids 3: e161). This strategy has been successfully applied to cells of several different species, including maize and soybean (US20150082478, published March 19, 2015). A method for expressing RNA components without a 5' cap has been described (WO 2016 / 025131, published February 18, 2016).
[0434] A variety of methods and compositions can be used to obtain cells or organisms having a polynucleotide of interest inserted into a target site for Cas endonuclease. Such methods may employ homologous recombination (HR) to integrate the polynucleotide of interest at the target site. In one method described herein, the polynucleotide of interest is introduced into the biological cell by means of a donor DNA construct.
[0435] The donor DNA construct further comprises first and second regions of homology that flank the polynucleotide of interest. The first and second homologous regions of the donor DNA have homology to the first and second genomic regions, respectively, that are present in or adjacent to the target site of the genome of the cell or organism.
[0436] Donor DNA can be bound to a guide polynucleotide. Tethered donor DNA may allow co-localization of target and donor DNA useful for genome editing, gene insertion and regulation of the target genome, and the function of the endogenous HR machinery is greatly enhanced. It may be useful for targeting postmitotic cells that are thought to be depressed (Mali et al., 2013, Nature Methods Vol. 10:957-963).

The amount of homology can also be expressed in percent sequence identity over the fully aligned length of two polynucleotides, including at least about 50%, 55%, 60%, 65%, 70% %, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 98%~99%, 99%, 99%~100% or 100% percent sequence identity. Sufficient homology includes any combination of polynucleotide length, overall percent sequence identity, and optionally conserved regions of contiguous nucleotides or regional percent sequence identity, e.g. Homology can be described as a 75-150 bp region with at least 80% sequence identity to the region of the target locus. Sufficient homology can also be explained by the predictive ability of two polynucleotides to hybridize specifically under conditions of high stringency, see, for example, Sambrook et al., (1989) Molecular Cloning: A Laboratory Manual, ( Cold Spring Harbor Laboratory Press, NY); Current Protocols in Molecular Biology, Ausubel et al., Eds (1994) Current Protocols, (Greene Publishing Associates, Inc. and John Wiley & Sons, Inc.); and Tijssen (1993) Laboratory Techniques in See Biochemistry and Molecular Biology--Hybridization with Nucleic Acid Probes, (Elsevier, New York).
[0438] The structural similarity between a given genomic region and the corresponding homologous region found on the donor DNA can be any degree of sequence identity that allows homologous recombination to occur. For example, the amount of homology or sequence identity shared by the "homologous region" of the donor DNA and the "genomic region" of the organism genome is such that those sequences undergo homologous recombination, at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92% , 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence identity.
[0439] A homologous region on the donor DNA can have homology to any sequence that flanks the target site. In some instances, the region of homology shares considerable sequence homology to genomic sequences immediately adjacent to the target site, but this region of homology may be further 5' or 3' to the target site. It will be appreciated that regions can be designed to have sufficient homology. A homologous region can have homology to fragments of the target site as well as downstream genomic regions.
[0440] In one embodiment, the first region of homology further comprises a first fragment of the target site and the second region of homology comprises a second fragment of the target site, the first fragment and the second fragment being different.
[0441] Polynucleotide of interest Polynucleotides of interest are described in detail herein and include polynucleotides that reflect commercial market interests related to commercial markets and crop development. Target crops and markets will change, and new crops and technologies will emerge as developing countries expand their global markets. Moreover, as our understanding of agronomic traits and characteristics such as yield and hybrid vigor increases, the selection of genes for genetic modification will change accordingly.
[0442] General categories of polynucleotides of interest include, for example, genes involved in information, such as zinc fingers, genes involved in transduction, such as kinases, and genes involved in housekeeping, such as heat shock proteins. Polynucleotides of more specific interest include, but are not limited to, crop yield, grain quality, grain nutrient content, starch and carbohydrate quality and quantity and grain size, sucrose load, protein quality and Genes involved in traits of agronomic interest, such as those affecting abundance, nitrogen fixation and / or utilization, fatty acid and oil composition, abiotic stresses (drought, nitrogen, temperature, salinity, toxic metals or trace elements or pesticides). genes encoding proteins that confer resistance to biological stresses (such as those that confer resistance to toxins such as pesticides and herbicides); including, but not limited to, genes that encode proteins that confer resistance to disease progression, such as cancer.
[0443] Agronomically important traits such as oil, starch and protein content can be genetically modified in addition to using conventional breeding methods. Modifications include increasing oleic acid, saturated and unsaturated oil content, increasing lysine and sulfur levels, providing essential amino acids, and also modifying starch. Modifications of the holidothionin protein are described in US Pat. Nos. 5,703,049, 5,885,801, 5,885,802 and 5,990,389.
[0444] A polynucleotide sequence of interest may encode a protein involved in the induction of disease or pest resistance. "Disease resistance" or "pest resistance" means that plants avoid harmful symptoms that are the result of plant-pathogen interactions. Pest resistance genes can encode resistance to pests that inhibit high yields, such as liceworm, cutworm, European corn borer. Disease and insect resistance genes such as lysozyme or cecropins that protect antibacterial properties or proteins such as defensins, glucanases or chitinases that protect antifungal properties or Bacillus thuringiensis endotoxins, proteases that control nematodes or insects. Inhibitors, collagenases, lectins or glucosidases are all examples of useful gene products. Genes encoding disease resistance traits include detoxification genes such as against fumonisins (U.S. Pat. No. 5,792,931), avirulent (avr) genes and disease resistance (R) genes (Jones et al. (1994) Science 266). :789; Martin et al. (1993) Science 262:1432; and Mindrinos et al. (1994) Cell 78:1089). Insect resistance genes can encode resistance to pests that inhibit high yields, such as liceworm, cutworm, European corn borer. Such genes include, for example, the Bacillus thuringiensis toxic protein gene (U.S. Pat. Nos. 5,366,892; 5,747,450; 5,736,514; 5,723,756; 5,593,881; and Geiser et al. (1986) Gene 48:109).
[0445] A protein obtained by expression of a "herbicide resistance protein" or a "nucleic acid molecule encoding herbicide resistance" has the ability to tolerate higher concentrations of herbicides than cells that do not express the protein, or the ability to tolerate higher concentrations of herbicides than cells that do not express the protein. Proteins that confer on cells the ability to tolerate specific concentrations of herbicides for a period of time are included. Herbicide tolerance traits are herbicides that act to inhibit the action of acetolactate synthase (ALS, also called acetohydroxyacid synthase, AHAS), particularly sulfonylurea (UK: sulphonylurea). )-type herbicides, genes encoding tolerance to herbicides that act to inhibit the action of glutamine synthetase, such as phosphinothricin or basta (e.g., the bar gene), tolerance to glyphosate Introduced into plants by encoding genes (e.g. EPSP synthase gene and GAT gene), genes encoding resistance to HPPD inhibitors (e.g. HPPD gene) or other such genes known in the art can do. For example, U.S. Pat. See US Patent No. 9,187,762. The bar gene encodes resistance to the herbicide basta, the nptII gene encodes resistance to the antibiotics kanamycin and geneticin, and the ALS gene mutant encodes resistance to the herbicide chlorsulfuron.
[0446] Additionally, the polynucleotide of interest can also include an antisense sequence complementary to at least a portion of the messenger RNA (mRNA) for the targeted gene sequence of interest. Antisense nucleotides are constructed to hybridize with the corresponding mRNA. Modifications of the antisense sequence can be made so long as the sequence hybridizes to the corresponding mRNA and prevents expression of the corresponding mRNA. Antisense constructs with 70%, 80% or 85% sequence identity to the corresponding antisense sequence can be used in this method. In addition, antisense nucleotide moieties can be used to interfere with target gene expression. Generally, sequences of at least 50 nucleotides, 100 nucleotides, 200 nucleotides or more may be used.
[0447] Furthermore, the polynucleotide of interest can be used in a sense orientation to suppress expression of endogenous genes in the plant. Methods for suppressing gene expression in plants by polynucleotides in the sense orientation are known in the art. The method generally involves transforming a plant with a DNA construct comprising a promoter driving expression in the plant, operably linked to at least a portion of a nucleotide sequence corresponding to transcription of an endogenous gene. is included. Typically, such nucleotide sequences have substantial sequence identity, generally greater than about 65% sequence identity, greater than about 85% sequence identity, or greater than about 95% sequence identity, to the transcribed sequence of the endogenous gene. have sex. See US Pat. Nos. 5,283,184 and 5,034,323.
[0448] A polynucleotide of interest can also be a phenotypic marker. Phenotypic markers are screening or selectable markers, including visual and selectable markers, whether positively or negatively selectable. Any phenotypic marker can be used. In particular, selectable or screening markers often identify, or select favorably or against favorably, a molecule or cell containing a molecule or cell under certain conditions. contains a DNA segment that allows These markers can encode activities such as, but not limited to, the production of RNA, peptides or proteins, or provide binding sites for RNA, peptides, proteins, inorganic and organic compounds or compositions such as be able to.
[0449] Examples of selectable markers include, but are not limited to, DNA segments containing restriction enzyme sites; spectinomycin, ampicillin, kanamycin, tetracycline, Basta, neomycin phosphotransferase II (NEO) and hygromycin phosphotransferase (HPT)). DNA segments encoding products that provide resistance to otherwise toxic compounds, including antibiotics; DNA segments encoding products that are otherwise missing in recipient cells (e.g., tRNA genes, auxotrophic markers); DNA segments encoding readily identifiable products (e.g., phenotypic markers such as β-galactosidase, GUS; green fluorescent protein (GFP), cyan (CFP), yellow (YFP), red (RFP); ) fluorescent proteins such as fluorescent proteins and cell surface proteins); generation of novel primer sites for PCR (e.g. alignment of two previously unaligned DNA sequences), restriction endonucleases or other DNA modifying enzymes. , the inclusion of DNA sequences that have been unaffected or subjected to effects such as chemicals, as well as the inclusion of DNA sequences that are required for specific modifications (eg, methylation) that allow their identification.
[0450] Additional selectable markers include genes that confer resistance to herbicidal compounds such as sulfonylureas, glufosinate-ammonium, bromoxynil, imidazolinones and 2,4-dichlorophenoxyacetate (2,4-D). For example, acetolactate synthase (ALS) resistant to sulfonylureas, imidazolinones, triazolopyrimidinesulfonamides, pyrimidinyl salicylates and sulfonylaminocarbonyltriazolinones (Shaner and Singh, 1997, Herbicide Activity: Toxicol Biochem Mol Biol 69 -110); glyphosate-tolerant 5-enolpyruvylshikimate-3-phosphate (EPSPS) (Saroha et al., 1998, J. Plant Biochemistry & Biotechnology Vol 7:65-72).
[0451] Polynucleotides of interest include genes that can be stacked or used in combination with other traits, such as, but not limited to, herbicide tolerance or any other trait described herein. Polynucleotides and / or traits of interest are described in U.S. Patent Application Publication No. 20130263324, published Oct. 3, 2013 and International Publication No. WO 2013 / 112686, published Aug. 1, 2013 can be stacked together into compound trait loci as shown.
[0452] Polypeptides of interest include any protein or polypeptide encoded by the polynucleotides of interest described herein.
[0453] Further provided is a method of identifying at least one plant cell that contains in its genome a polynucleotide of interest integrated at a target site. Various methods can be used to identify plant cells with insertions at or near the target site of the genome. Such methods can be considered direct analysis of the target sequence to detect alterations in the target sequence and include, but are not limited to, PCR, sequencing, nuclease digestion, Southern blotting and Any combination of these is included. See, for example, US Patent Application Publication No. 20090133152, published May 21, 2009. The method also includes recovering plants from plant cells that contain the polynucleotide of interest integrated into the genome. Plants can be sterile or fertile. Any polynucleotide of interest can be provided, integrated into a target site in the genome of a plant, and expressed in the plant.
[0454] Sequence optimization for expression in plants Methods for synthesizing plant-preferred genes are available in the art. See, eg, US Pat. Nos. 5,380,831 and 5,436,391 and Murray et al. (1989) Nucleic Acids Res. 17:477-498. Additional sequence modifications are known to enhance gene expression in plant hosts. These modifications include, for example, removal of one or more sequences encoding spurious polyadenylation signals, removal of one or more exon-intron splice site signals, removal of one or more transposon-like repeats and gene Removal of such other well-characterized sequences that may be detrimental to expression is included. The GC content of the sequences can be adjusted to the average level for a given plant host (calculated with reference to known genes expressed in that host plant cell). If possible, modify the sequence to avoid predicted hairpin secondary structures in one or more mRNAs. Accordingly, the "plant-optimized nucleotide sequences" of this disclosure include one or more modifications of such sequences.
[0455] expression element Any polynucleotide encoding a Cas protein or other CRISPR system component disclosed herein can be operably linked to heterologous expression elements to facilitate transcription or regulation in a host cell. Such expression elements include, but are not limited to, promoters, leaders, introns, terminators. An expression element can be "minimal," meaning a short sequence derived from a natural source that still functions as an expression regulator or modifier. Alternatively, an expression element can be "optimized," meaning that its polynucleotide sequence has been altered from its natural state in order to function with more desirable characteristics in a particular host cell. (eg, but not limited to, a bacterial promoter can be "maize optimized" to improve its expression in maize plants). Alternatively, the expression element can be "synthetic," meaning that the expression element is designed in silico and synthesized for use in the host cell. Synthetic expression elements can be wholly synthetic or partially synthetic (including fragments of naturally occurring polynucleotide sequences).
[0456] Certain promoters have been shown to be able to induce RNA synthesis at a higher rate than others. These are called "strong promoters". Certain other promoters have been shown to induce synthesis of RNA at high levels only in certain cell or tissue types, with promoters preferentially inducing RNA synthesis in certain tissues and at low levels in other tissues. It is often referred to as a "tissue-specific promoter" or "tissue-preferred promoter" when it induces RNA synthesis in .

[0461] Chemically inducible (regulated) promoters can be used to regulate gene expression in prokaryotic and eukaryotic cells or organisms by application of exogenous chemical regulatory agents. The promoter can be a chemically inducible promoter, in which application of a chemical induces gene expression, or a chemically repressible promoter, in which application of a chemical represses gene expression.

Other chemically regulated promoters include steroid-responsive promoters (e.g., glucocorticoid-inducible promoters (Schena et al., (1991) Proc. Natl. Acad. Sci. USA 88:10421-5; McNellis et al., (1998)). ) Plant J 14:247-257); tetracycline-inducible and tetracycline-repressible promoters (Gatz et al., (1991) Mol Gen Genet 227:229-37; U.S. Pat. Nos. 5,814,618 and 5,814,618); 5,789,156).

[0463] Stress-inducible promoters include the RD29A promoter (Kasuga et al. (1999) Nature Biotechnol. 17:287-91). Those skilled in the art are familiar with protocols for simulating stress conditions such as drought, osmotic stress, salt stress and temperature stress, as well as protocols for assessing stress tolerance of plants subjected to simulated or naturally occurring stress conditions. Familiar with.
[0464] Another example of an inducible promoter useful for plant cells is the ZmCAS1 promoter described in US Patent Application Publication No. 20130312137, published Nov. 21, 2013.
[0465] A wide variety of new promoters useful in plant cells are constantly being discovered, many examples can be found in Okamuro and Goldberg, eds. (1989) The Biochemistry of Plants, Vol. 115, Stumpf and Conn, eds (New York, NY). : Academic Press), pp. 1-82.
[0466] Genome modification with novel CRISPR-Cas system components As described herein, the derived Cas endonuclease can recognize and bind DNA target sequences and introduce single-strand (nicks) or double-strand breaks. When a single-strand or double-strand break is introduced into DNA, the cell's DNA repair machinery is activated to repair the break. Error-prone DNA repair machinery can create mutations at double-strand break sites. The most common repair mechanism for joining broken ends together is the non-homologous end joining (NHEJ) pathway (Bleuyard et al., (2006) DNA Repair 5:1-12). The structural integrity of chromosomes is typically maintained by repair, although deletions, insertions or other rearrangements (such as chromosomal translocations) are possible (Siebert and Puchta, 2002, Plant Cell 14:1121). -31; Pacher et al., 2007, Genetics 175:21-9).
[0467] DNA double-strand breaks appear to be effective factors for stimulating the homologous recombination pathway (Puchta et al., (1995) Plant Mol Biol 28:281-92; Tzfira and White, (2005) Trends Biotechnol 23:567-9; Puchta, (2005) J Exp Bot 56:1-14). A 2- to 9-fold increase in homologous recombination between artificially constructed homologous DNA repeats in plants has been observed using DNA cutting agents (Puchta et al., (1995) Plant Mol Biol 28:281- 92). Experiments with linear DNA molecules in maize protoplasts demonstrated enhanced homologous recombination between plasmids (Lyznik et al., (1991) Mol Gen Genet 230:209-18).
[0468] Homologous recombination repair (HDR) is a mechanism that repairs intracellular double- and single-stranded DNA breaks. Homologous recombination repair includes homologous recombination (HR) and single-strand annealing (SSA) (Lieber.2010 Annu.Rev.Biochem.79:181-211). The most common form of HDR is called homologous recombination (HR) with the longest sequence homology requirement between donor and acceptor DNA. Other forms of HDR include single-strand annealing (SSA) and break-induced replication, which require shorter sequence homology compared to HR. Homologous recombination repair at nicks (single-strand breaks) may occur by a different mechanism than HDR for double-strand breaks (Davis and Maizels. PNAS (0027-8424), 111(10), p.E924-E932) .
[0469] For example, modification of the genomes of prokaryotic and eukaryotic living or biological cells by homologous recombination (HR) is a powerful tool for genetic engineering. Homologous recombination has been demonstrated in plants (Halfter et al., (1992) Mol Gen Genet 231:186-93) and insects (Dray and Gloor, 1997, Genetics 147:689-99). Homologous recombination has also been achieved in other organisms. For example, homology of at least 150-200 bp was required for homologous recombination in the protozoan parasite Leishmania (Papadopoulou and Dumas, (1997) Nucleic Acids Res 25:4278-86). In the filamentous fungus Aspergillus nidulans, gene replacement has been achieved with as little as 50 bp of flanking homology (Chaveroche et al., (2000) Nucleic Acids Res 28:e97). Targeted gene replacement has also been demonstrated in the ciliate Tetrahymena thermophila (Gaertig et al., (1994) Nucleic Acids Res 22:5391-8). In mammals, homologous recombination has been most successful in mice using pluripotent embryonic stem cell lines (ES) that can be grown in culture, transformed, selected, and introduced into mouse embryos. Watson et al., 1992, Recombinant DNA, 2nd Ed., Scientific American Books distributed by WH Freeman & Co.).
[0470] gene targeting The guide polynucleotide / Cas system described herein can be used for gene targeting.
[0471] In general, DNA targeting can be carried out by cleaving one or both strands at a specific polynucleotide sequence in a cell in which the Cas protein associates with a suitable polynucleotide component. When a single-strand or double-strand break is induced in DNA, the cell's DNA repair machinery is activated and repairs the break by non-homologous end joining (NHEJ) or homologous recombination repair (HDR) processes to target It can lead to modification of the site.
[0472] The length of the target site DNA sequence may vary, e.g. , 28, 29, 30 or more than 30 nucleotides. The target site may be palindromic, ie, it is further possible that a sequence on one strand reads the same in opposite directions on the complementary strand. The nicks / cleavage sites can be within the target sequence or the nicks / cleavage sites can be outside the target sequence. In another variation, cleavage can occur at nucleotide positions directly opposite each other, resulting in blunt-end cleavage, and in other cases, the nicks are offset, resulting in single-stranded overhangs (5 ' overhang or 3' overhang). Active mutants of genomic target sites can also be used. Such active variants are at least 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96% active against a given target site. %, 97%, 98%, 99% or more sequence identity, active variants retain biological activity and can therefore be recognized and cleaved by a Cas endonuclease.
[0473] Assays for measuring target site single- or double-strand cleavage by endonucleases are known in the art and generally involve the overall activity and specificity of an agent to a DNA substrate containing a recognition site. to measure.
[0474] The targeting method herein can be performed such that, for example, more than one DNA target site is targeted in the method. Such methods may optionally be characterized as multiplex methods. In certain embodiments, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more target sites may be targeted simultaneously. Multiplex methods are generally provided herein with a plurality of different RNA components, each of which is designed to direct the guide polynucleotide / Cas endonuclease complex to a unique DNA target site. is implemented by the targeting method of
[0475] gene editing The process of editing a genome sequence that combines a DSB and a modified template generally involves recognizing a target sequence in a chromosomal sequence and introducing a DSB inducer or a nucleic acid encoding a DSB inducer capable of introducing a DSB into a genomic sequence and a nucleic acid to be edited. Introducing into the host cell at least one polynucleotide modified template that contains at least one nucleotide modification compared to the nucleotide sequence. A polynucleotide modification template can further comprise a nucleotide sequence that flanks the at least one nucleotide modification. The flanking sequences are substantially homologous to chromosomal regions flanking the DSB. Genome editing using DSB inducers, such as Cas-gRNA complexes, is described, for example, in U.S. Patent Application Publication No. 20150082478 published March 19, 2015; Publication No. 2015026886, WO2016007347 published January 14, 2016 and WO2016 / 025131 published February 18, 2016.
[0476] Several uses of guide RNA / Cas endonuclease systems have been described (e.g., US Patent Application Publication No. 20150082478A1, published March 19, 2015, published February 26, 2015). See International Publication No. WO2015026886 and U.S. Patent Application Publication No. 20150059010, published Feb. 26, 2015), which include alterations or substitutions of nucleotide sequences of interest (such as regulatory elements), Insertion of polynucleotide, gene knockout, gene knock-in, splicing site modification and / or introduction of alternative splicing site, modification of the nucleotide sequence encoding the target protein, amino acid and / or protein fusion and inverted repeats in the target gene including, but not limited to, gene silencing by expressing .
[0477] Proteins can be altered in a variety of ways, including amino acid substitutions, deletions, truncations and insertions. Methods for such manipulations are generally known. For example, amino acid sequence variants of proteins can be prepared by mutations within the DNA. Methods of mutagenesis and nucleotide sequence alteration include, for example, Kunkel, (1985) Proc. Natl. Acad. Sci. See Patent No. 4,873,192; Walker and Gaastra, eds. (1983) Techniques in Molecular Biology (MacMillan Publishing Company, New York) and references cited therein. Guidance for amino acid substitutions that are unlikely to affect the biological activity of a protein is found, for example, in the model of Dayhoff et al. (1978) Atlas of Protein Sequence and Structure (Natl Biomed Res Found, Washington, D.C.). . Conservative substitutions, such as exchanging one amino acid with another having similar properties, may be preferred. Conservative deletions, insertions, and amino acid substitutions are not expected to cause drastic changes in protein properties, and the effects of substitutions, deletions, insertions, or combinations thereof can be evaluated in routine screening assays. can. Assays for double-strand break-inducing activity are known and generally measure the overall activity and specificity of an agent on a DNA substrate containing a target site.
[0478] Described herein are methods of genome editing using Cas endonucleases and complexes comprising Cas endonucleases and guide polynucleotides. Following characterization of the guide RNA and PAM sequences, endonucleases and related CRISPR RNA (crRNA) components can be utilized to modify chromosomal DNA in other organisms, including plants. To facilitate optimal expression and nuclear localization (for eukaryotic cells), genes containing complexes are optimized as described in WO2016186953 published Nov. 24, 2016. , and subsequently delivered to cells as a DNA expression cassette by methods known in the art. The components necessary to contain the active complex are as RNA with or without modifications that protect the RNA from degradation, i.e. as capped or uncapped mRNA (Zhang, Y. et al., 2016, Nat. Commun. 7:12617) or as a Cas protein guide polynucleotide complex (WO2017070032 published April 27, 2017) or any combination thereof. Furthermore, one or more parts of the complex and the crRNA can be expressed from a DNA construct, while the other components can be expressed as RNA with or without modifications that protect the RNA from degradation, i.e. capped or As an uncapped mRNA (Zhang et al.2016 Nat.Commun.7:12617) or as a Cas protein guide polynucleotide complex (WO2017070032 published April 27, 2017), or any of these can be delivered as a combination of To generate crRNA in vivo, a tRNA-derived element is used to direct the crRNA transcript to its DNA target site, e.g., as described in WO2017105991, published June 22, 2017. endogenous RNAse can be recruited to cleave to the mature form that can induce the complex to Nickase complexes can be used individually or in concert to generate single or multiple DNA nicks on one or both of the DNA strands. Furthermore, the cleavage activity of the Cas endonuclease can be inactivated by modifying key catalytic residues in its cleavage domain (Sinkunas, T et al., 2013, EMBO J.32:385-394), The result is an RNA-guided helicase that can be used to enhance homologous recombination repair, induce transcriptional activation, or remodel DNA local structures. Furthermore, the Cas cleavage domain and helicase domain activities are both knocked out and other DNA cleavages, DNA nicking, DNA binding, transcriptional activation, transcriptional repression, DNA reassembly, DNA deamination, DNA unwinding, DNA It can be used in combination with recombination enhancement, DNA integration, DNA inversion and DNA repair agents.
[0479] Transcriptional directions of the CRISPR-Cas system tracrRNA (if present) and other components of the CRISPR-Cas system (e.g., variable targeting domains, crRNA repeats, loops, anti-repeats) were published on Nov. 24, 2016. It can be estimated as described in WO2016186946 and WO2016186953 published on November 24, 2016.
[0480] Once the appropriate guide RNA requirements are established, as described herein, the PAM preferences for each new system disclosed herein can be examined. If the cleavage complex results in degradation of the randomized PAM library, either by mutagenesis of key residues or by assembling the reaction in the absence of ATP as previously described (Sinkunas, T. et al. ., 2013, EMBO J.32:385-394), the complex can be converted to a nickase by abolishing the ATPase-dependent helicase activity. Two regions of PAM randomization separated by two protospacer targets can be utilized to generate double-stranded DNA breaks that are captured and sequenced to support cleavage by the respective complexes. can be examined.
[0481] In one embodiment, the invention describes a method of modifying a target site in the genome of a cell. The method comprises introducing into a cell at least one PGEN described herein and identifying at least one cell having an alteration in said target, wherein said alteration at said target site comprises (i) at least one (ii) deletion of at least one nucleotide; (iii) insertion of at least one nucleotide; chemical alteration of at least one nucleotide; and (v) any combination of (i) to (iv) selected from the group consisting of
[0482] The edited nucleotide can be located within or outside the target site recognized and cleaved by the Cas endonuclease. In one embodiment, the at least one nucleotide modification is not at the target site recognized and cleaved by the Cas endonuclease. In another embodiment, between at least one nucleotide to be edited and the genomic target site, at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 , 27, 30, 40, 50, 100, 200, 300, 400, 500, 600, 700, 900 or 1000 nucleotides.
[0483] Knockouts can be generated by indels (insertions or deletions of nucleotide bases in the target DNA sequence by NHEJ) or by specific removal of sequences that reduce or completely abolish the function of sequences at or near the target site.
[0484] Guide polynucleotide / Cas endonuclease-directed targeted mutations can occur within nucleotide sequences located within or outside the genomic target site recognized and cleaved by the Cas endonuclease.
[0485] Methods for editing nucleotide sequences in the genome of cells may be methods that do not use exogenous selectable markers by restoring the function of non-functional gene products.
[0486] In one embodiment, the invention describes a method for modifying a target site in the genome of a cell. The method comprises introducing into a cell at least one PGEN as described herein and at least one donor DNA, said donor DNA comprising a polynucleotide of interest and optionally at or near said target site. identifying at least one cell that has integrated said polynucleotide of interest into.
[0487] In one aspect, the methods disclosed herein may employ homologous recombination (HR) to provide for integration of the polynucleotide of interest at the target site.
[0488] Various methods and compositions can be used to generate cells or organisms with a polynucleotide of interest inserted into a target site by the activity of the CRISPR-Cas system components described herein. In one method described herein, a polynucleotide of interest is introduced into a biological cell by means of a donor DNA construct. As used herein, "donor DNA" is a DNA construct containing a polynucleotide of interest to be inserted into the Cas endonuclease target site. The donor DNA construct further comprises first and second regions of homology that flank the polynucleotide of interest. The first and second homologous regions of the donor DNA have homology to the first and second genomic regions, respectively, that are present in or adjacent to the target site of the genome of the cell or organism.
[0489] Donor DNA can be tethered to a guide polynucleotide. Tethered donor DNA may allow co-localization of target and donor DNA useful for genome editing, gene insertion and regulation of the target genome, and the function of the endogenous HR machinery is greatly enhanced. It may be useful for targeting postmitotic cells that are thought to be depressed (Mali et al., 2013, Nature Methods Vol. 10:957-963).
[0490] The amount of homology or sequence identity shared by the target and donor polynucleotides can vary and can range from about 1-20 bp, 20-50 bp, 50-100 bp, 75-150 bp, 100-250 bp, 150-300 bp, 200-400bp, 250-500bp, 300-600bp, 350-750bp, 400-800bp, 450-900bp, 500-1,000bp, 600-1,250bp, 700-1,500bp, 800-1,750bp, 900-2,000bp, 1 ~2.5 kb, 1.5-3 kb, 2-4 kb, 2.5-5 kb, 3-6 kb, 3.5-7 kb, 4-8 kb, 5-10 kb, or full length with unit integer values within the range up to the full length of the target site and / or Includes all areas. These ranges include all integers within this range, e.g. 13, 14, 15, 16, 17, 18, 19 and 20bp are included. The amount of homology can also be described as percent sequence identity over the fully aligned length of the two polynucleotides, including at least about 50%, 55%, 60%, 65%, 70% , 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87 %, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% percent sequence identity. Sufficient homology includes any combination of polynucleotide length, overall percent sequence identity, and optionally conserved regions of contiguous nucleotides or regional percent sequence identity, e.g. Homology can be described as a 75-150 bp region with at least 80% sequence identity to the region of the target locus. Sufficient homology can also be explained by the predictive ability of two polynucleotides to hybridize specifically under conditions of high stringency, see, for example, Sambrook et al., (1989) Molecular Cloning: A Laboratory Manual, ( Cold Spring Harbor Laboratory Press, NY); Current Protocols in Molecular Biology, Ausubel et al., Eds (1994) Current Protocols, (Greene Publishing Associates, Inc. and John Wiley & Sons, Inc.); and Tijssen (1993) Laboratory Techniques in See Biochemistry and Molecular Biology--Hybridization with Nucleic Acid Probes, (Elsevier, New York).
[0491] Episomal DNA molecules can also ligate within double-strand breaks, e.g., integrate T-DNA within chromosomal double-strand breaks (Chilton and Que, (2003) Plant Physiol 133:956-65; Salomon and Puchta , (1998) EMBO J 17:6086-95). If the sequences surrounding the double-strand break are modified, for example, by exonuclease activities involved in maturation of the double-strand break, the gene conversion pathway may be altered, for example, by nondividing somatic cells or sister chromatids after DNA replication. The original structure can be restored if homologous sequences, such as bodies, are available (Molinier et al., (2004) Plant Cell 16:342-52). Ectopic and / or epigenetic DNA sequences can also serve as DNA modification templates for homologous recombination (Puchta, (1999) Genetics 152:1173-81).
[0492] In one embodiment, the disclosure includes a method of editing a nucleotide sequence in the genome of a cell, comprising introducing into at least one PGEN and a polynucleotide modified template described herein (herein wherein said polynucleotide modified template comprises at least one nucleotide modification of said nucleotide sequence), optionally further comprising selecting at least one cell containing the edited nucleotide sequence.
[0493] The guide polynucleotide / Cas endonuclease system can be used in combination with at least one polynucleotide modification template to allow editing (modification) of the genomic nucleotide sequence of interest. (See also U.S. Patent Application Publication No. 20150082478, published March 19, 2015 and International Publication No. WO2015026886, published February 26, 2015).
[0494] The polynucleotide and / or trait of interest may be at a composite trait locus, as described in WO2012129373 published September 27, 2012 and WO2013112686 published August 1, 2013. Can be stacked together. The guide polynucleotide / Cas9 endonuclease system described herein provides a system for efficiently generating double-strand breaks, allowing stacking of traits at complex trait loci.
[0495] The guide polynucleotide / Cas system described herein mediating gene targeting is described in Methods for Directing Heterologous Gene Insertion and / or for Generating Complex Trait Loci Containing Multiple Heterologous Genes, September 2012 It can be used in a manner similar to that disclosed in WO2012129373, published on 27th, in which the use of a double-strand break-inducing agent is used to introduce the gene of interest. Instead, the guide polynucleotide / Cas system disclosed herein is used. Transgenes can be propagated as a single locus by inserting independent transgenes within 0.1, 0.2, 0.3, 0.4, 0.5, 1.0, 2 or 5 centimorgans (cM) of each other (e.g. , U.S. Patent Application Publication No. 20130263324 published Oct. 3, 2013 or WO 2012129373 published Mar. 14, 2013). After selection of transgene-containing plants, plants containing (at least) one transgene can be crossed to form an F1 containing both transgenes. Of these F1 (F2 or BC1) offspring, 1 / 500 offspring will have two different transgenes recombined on the same chromosome. This composite locus can then be bred with both transgenic traits as a single locus. By repeating this process, any number of desired traits can be accumulated.
[0496] Further uses of the guide RNA / Cas endonuclease system have been described (e.g., US Patent Application Publication No. 20150082478 published March 19, 2015; No. 2015026886, U.S. Patent Application Publication No. 20150059010 published February 26, 2015, International Publication No. 2016007347 published January 14, 2016 and February 18, 2016 PCT Application No. WO 2016025131), which includes alterations or substitutions of nucleotide sequences of interest (such as regulatory elements), insertions of polynucleotides of interest, gene knockouts, gene knockins, splicing site modifications. Gene silencing by introducing modifications and / or alternative splicing sites, modification of the nucleotide sequence encoding the protein of interest, amino acid and / or protein fusions and expression of inverted repeats in the gene of interest. is not limited to
[0497] Characteristics obtained from the gene-editing compositions and methods described herein can be evaluated. Chromosomal intervals that correlate with a phenotype or trait of interest can be identified. Various methods well known in the art are available for identifying chromosomal intervals. The boundaries of such chromosomal intervals are drawn to encompass the markers linked to the gene controlling the trait of interest. In other words, chromosomal intervals are determined such that any marker that lies within that interval (including terminal markers that define the boundaries of the interval) can be used as a marker for a particular trait. In one embodiment, a chromosomal interval includes at least one QTL, and may in fact include more than one QTL. The close proximity of multiple QTLs within the same interval obscures the association of a particular marker with a particular QTL, as one marker links to more than one QTL. Conversely, for example, if two markers in close proximity are co-segregating with a desired phenotypic trait, it is often difficult to determine whether each of these markers specifies the same QTL or two different QTLs. , it is ambiguous. The term "quantitative trait locus" or "QTL" refers to a region of DNA associated with differential expression of a quantitative phenotypic trait in at least one genetic background, eg, in at least one breeding population. QTL regions encompass or are closely associated with genes that affect the trait in question. A "QTL allele" can include multiple genes or other genetic elements within a contiguous genomic region or linkage group, such as a haplotype. A QTL allele can refer to haplotypes within a particular window, which is a contiguous genomic region that can be defined and tracked by a set of one or more polymorphic markers. A haplotype can be defined by a unique fingerprint of the allele at each marker position within a specific window.

[0503] A Cas endonuclease, such as the Cas endonucleases described herein, may be a Cas polypeptide itself (referred to as direct delivery of the Cas endonuclease), an mRNA encoding a Cas protein and / or a guide polynucleotide / Cas endonuclease complex itself. can be introduced into cells by direct introduction using any method known in the art. A Cas endonuclease can also be introduced into cells indirectly by introducing a recombinant DNA molecule encoding the Cas endonuclease. The endonuclease can be transiently introduced into the cell or integrated into the genome of the host cell using any method known in the art.

[0504] Direct delivery of polynucleotide-modified templates to plant cells can be achieved by particle-mediated delivery, including but not limited to polyethylene glycol (PEG)-mediated transfection of protoplasts, whisker-mediated transformation, electroporation, particles. Any other direct delivery method such as bombardment methods, cell permeable peptides or mesoporous silica nanoparticles (MSN) mediated direct protein delivery can be successfully used for delivery of polynucleotide modified templates in eukaryotic cells such as plant cells. .
[0505] Donor DNA can be introduced by any means known in the art. Donor DNA can be provided by any transformation method known in the art including, for example, Agrobacterium-mediated transformation or biolistic particle bombardment methods. The donor DNA may exist transiently within the cell or it may be introduced by a viral replicon. In the presence of the Cas endonuclease and target site, the donor DNA is inserted into the transformed plant genome.
[0506] Direct delivery of any one of the inducible Cas system components can facilitate enrichment and / or visualization of cells that receive the guide polynucleotide / Cas endonuclease complex components Direct delivery (co-delivery) of other mRNAs ). For example, the guide polynucleotide / Cas endonuclease component (and / or the guide polynucleotide / Cas endonuclease complex itself) may be used as a phenotypic marker, including but not limited to CRC (Bruce et al. 2000 The Plant Cell 12:65- 79) by direct co-delivery together with mRNAs encoding transcriptional activators such as ), as described in WO2017070032, published April 27, 2017. The function of the sex gene product can be restored, allowing selection and enrichment of cells without the use of exogenous selectable markers.
[0507] Introduction of the guide RNA / Cas endonuclease complexes described herein (representing the cleavage-ready complexes described herein) into cells may involve the individual components of said complexes either separately or Collectively into cells, either directly (delivered directly as RNA for guide and protein and protein subunits for Cas endonuclease, or functional fragments thereof) or as recombinant constructs expressing components (guide RNA, Cas endonuclease) nucleases, protein subunits or functional fragments thereof). Introducing a guide RNA / Cas endonuclease complex (RGEN) into a cell involves introducing the guide RNA / Cas endonuclease complex into the cell as a ribonucleotide-protein. Ribonucleotide-proteins can be assembled prior to introduction into cells, as described herein. The components that make up the guide RNA / Cas endonuclease ribonucleotide protein (at least one Cas endonuclease, at least one guide RNA, at least one protein subunit) are introduced in vitro or into cells (described herein). can be assembled by any means known in the art, prior to being targeted for genomic modification as is done).
[0508] Direct delivery of RGEN ribonucleoproteins enables genome editing at targeted sites in the cellular genome in such a way that the complexes are then rapidly disassembled and their existence within the cell is transient. . The transient presence of this RGEN complex can lead to reduced off-targets. In contrast, delivery of RGEN components (guide RNA, Cas9 endonuclease) by plasmid DNA sequences results in sustained expression of RGEN from these plasmids, which can increase off-targets (Cradick, T.J. et al. (2013) Nucleic Acids Res 41:9584-9592; Fu, Y et al. (2014) Nat. Biotechnol. 31:822-826).
[0509] Direct delivery involves any one component (e.g., at least one guide RNA, at least one Cas protein and optionally one additional protein) with a delivery matrix comprising microparticles (such as but not limited to gold particles, tungsten particles and silicon carbide whisker particles) (27 Apr 2017). See also WO2017070032, published on 2017). The delivery matrix may comprise any one of the components, eg Cas endonuclease, which is attached to a solid matrix (eg impacting particles).

[0514] Alternatively, polynucleotides can be introduced into a plant or plant cell by contacting the cell or organism with a virus or viral nucleic acid. Generally, such methods involve incorporating the polynucleotide into a viral DNA or RNA molecule. In some examples, the polypeptide of interest can be first synthesized as part of a viral polyprotein, which can then be proteolytically processed in vivo or in vitro to produce the desired recombinant protein. Methods for introducing polynucleotides, including viral DNA or RNA molecules, into plants and expressing the encoded proteins therein are known, see, for example, US Pat. See US Pat. Nos. 5,866,785, 5,589,367 and 5,316,931.
[0515] Polynucleotides or recombinant DNA constructs can be provided or introduced into prokaryotic and eukaryotic cells or organisms using a variety of transient transformation methods. Such transient transformation methods include, but are not limited to, direct introduction of polynucleotide constructs into plants.
[0516] Incorporating nucleic acids and proteins in any manner, including using molecules that facilitate the uptake of any or all components (proteins and / or nucleic acids) of an inducible Cas system, such as cell-permeable peptides and nanocarriers. , can be provided to cells. See also US Patent Application Publication No. 20110035836, published February 10, 2011 and European Patent Application Publication No. 2821486A1, published January 7, 2015.
[0517] Other methods of introducing polynucleotides into prokaryotic and eukaryotic cells or organisms or plant parts can be used, such as plastid transformation methods and methods of introducing polynucleotides into tissues from seedlings or mature seeds.
[0518] Stable transformation is intended to mean that a nucleotide construct introduced into an organism is integrated into the organism's genome and can be passed on to its progeny. Transient transformation is intended to mean that either the polynucleotide is introduced into the organism but does not integrate into the organism's genome, or the polypeptide is introduced into the organism. Transient transformation means that the introduced composition is expressed or present only transiently within the organism.
