Description

Plant promoter for transfer gene expression and 3'UTR

The present invention is generally related to the field of plant molecular biology, and more particularly to the field of expressing transgenic genes in plants.

Many plant varieties can be transformed into transgenic genes to introduce agronomically desirable traits or characteristics. The resulting plant variety is developed and/or modified to have a particular desired trait. In general, desirable traits include, for example, improving nutritional value quality, increasing yield, imparting pest or disease resistance, increasing drought and stress tolerance, and improving horticultural quality ( eg , pigmentation and growth) (eg, pigmentation) Suspension and growth), imparting herbicide tolerance, enabling the production of industrially applicable compounds and/or materials from plants, and/or enabling the production of pharmaceuticals.

A gene transfer plant variety comprising a plurality of transgenic genes stacked at a single genomic locus is produced via a plant transformation technique. The plant transformation technique allows the transgenic gene to be introduced into plant cells, and the fertile gene-transplanted plants containing the stably integrated transgenic gene copies in the plant genome are replied, and then the transcriptional genes are translated and translated through the plant genome for expression of the transgenic genes. Geneogenic plants with desirable traits and phenotypes are produced. However, it is desirable to have mechanisms for generating engineered transgenic genes that are genetically transgenic plant species that are highly representative of multiple trait stacks.

Similarly, mechanisms are also expected to be used in specific tissues or organs of plants. Now the gene is transferred. For example, plant resistance to soil-borne pathogen infection can be increased by transforming the plant genome with a pathogen resistance gene, allowing the pathogen resistance protein to be stably expressed within the plant root. Alternatively, it may be desirable to be able to express a transgene in plant tissue in a particular growth or developmental stage, such as cell division or elongation. In addition, it may be desirable to express transgenic genes in the leaf and stem tissues of plants to provide tolerance to herbicides or to insects and pests on the ground.

I. Overview of several embodiments

The development of genetically modified plant products is becoming more and more complicated. Gene transfer plants that are commercially viable today require stacking multiple transgenic genes into a single locus. Plant promoters for basic research or biotechnology applications are generally unidirectional with the 3'UTR and are used only to introduce a gene that has been fused at its 3' end (downstream) for the promoter line, or one for the 3 The 'UTR line has been fused to its 5' end (upstream) gene. Thus, each transgene requires a promoter and a 3' UTR for performance, where multiple transgenic lines within a gene stack require multiple regulatory elements. As the number of transgenic genes in the gene stack increases, it is customary to use the same promoter and/or 3' UTR to obtain optimal levels of different transgene expression patterns. Optimal performance of the transgenic gene is required to produce a single polygenic trait. Unfortunately, it has been known that multi-gene constructs driven by the same promoter and/or 3' UTR cause gene silencing, resulting in fewer effective gene transfer products in the art. Repeated promoters and/or 3' UTR elements can cause homology-based gene silencing. In addition, repeats within the transgene can cause homology of the gene within the locus. Recombination results in rearrangement of the polynucleotides. Silencing and rearrangement of the transgenic genes may have undesired effects on the performance of the transgenic plants produced to express the transgenic genes. Furthermore, an excess of transcription factor (TF) binding sites due to promoter duplication can cause endogenous TF depletion, causing transcriptional inactivation. Given the need to introduce multiple genes into plants for metabolic engineering and trait stacking, multiple promoters and/or 3' UTRs are required to generate gene-transgenic crops that can drive multiple gene expression.

A particular problem in the identification of promoters and/or 3'UTRs is the need to identify tissue-specific promoters that are not expressed in other plant tissues associated with specific cell types, developmental stages and/or functions in plants. Tissue specificity ( ie, preference in tissue) or organ-specific promoters drive gene expression in a tissue such as the nut, root, leaf, silk or trophic layer of the plant. Tissue and developmental stage-specific promoters and/or 3'UTRs are initially identified by the expression of the observed genes that are expressed in a particular tissue or during a particular time period during plant development. These tissue-specific promoters and/or 3'UTR lines are required for certain applications in the gene transfer plant industry, and because they can desirably allow heterologous genes to be specifically selected in a tissue and/or developmental stage selectively Sexual performance indicates that heterologous genes are differentially expressed in various organs, tissues, and/or time, but not in other tissues. For example, plant resistance to soil-borne pathogen infection can be increased by transforming the plant genome with a pathogen resistance gene, allowing the pathogen resistance protein to be stably expressed within the plant root. Alternatively, it may be desirable to be able to express a transgene in plant tissue in a particular growth or developmental stage, such as cell division or elongation. Another application is the desire to use tissue-specific promoters and/or 3'UTRs to limit the expression of these agronomic trait-transforming genes in specific tissue types, such as developing parenchyma cells. Thus, a particular problem in the identification of promoters and/or 3'UTRs is how to identify promoters and how to correlate the identified promoters with the developmental characteristics of the cells for specific tissue manifestations.

Another problem with the identification of promoters is the need to select all relevant cis-acting and trans-activated transcriptional control elements so that the selected DNA fragments drive transcription in the desired specific pattern of expression. Considering that such a control element is located at the distal end of the translation initiation or start site, the size of the polynucleotide selected to include the promoter provides the degree of expression and performance pattern of the promoter polynucleotide sequence to It is important. The length of the promoter is known to contain functional information, and different genes have been shown to have promoters that are longer or shorter than the promoters of other genes in the genome. It is challenging to elucidate the transcription initiation site of the promoter and predict the functional gene elements in the promoter region. Also of added challenge is the complexity, diversity, and inherent degeneracy of the regulatory motifs and cis and trans regulatory elements (Blanchette, Mathieu, et al., "Genome-wide computational prediction of transcriptional regulatory modules reveals new insights Into human gene expression." Genome research 16.5 (2006): 656-668). The cis- and trans-regulatory elements are located in the distal portion of the promoter, and the promoter regulates the spatial and temporal expression of the gene to appear only at the desired site and at a specific time (Porto, Milena Silva, et al., "Plant promoters :an approach of structure and function." Molecular biotechnology 56.1 (2014): 38-49). Existing promoter analysis tools cannot reliably identify such cis-regulatory elements in genomic sequences, thus predicting excessive misjudgments, as these tools generally focus only on sequence content (Fickett JW, Hatzigeorgiou AG (1997) Eukaryotic promoter recognition. Genome research 7:861-878). Thus, the identification of a promoter regulatory element requires the acquisition of an appropriate sequence of a particular size that will result in a driven expression of an operably linked transgene in a desired manner.

The present invention provides methods and compositions for overcoming such problems by using a maize chlorophyll a/b binding protein gene regulatory element to express a transgene in a plant .

Caused by the production of double-stranded RNA (dsRNA) or transcribed sequences. Each process involves different cellular components, suggesting that dsRNA-induced TGS and PTGS may be diversified by ancient common mechanisms. However, a strict comparison of TGS and PTGS is difficult to achieve because it generally relies on the analysis of different silencing loci. In some cases, a single transgenic locus can trigger TGS and PTGS due to the generation of dsRNAs corresponding to promoters and transcripts of different target genes. Mourrain et al.

The transcriptional line proceeds along the DNA strand in a 5' to 3' fashion. This means that RNA is produced by sequentially adding ribonucleotide-5'-triphosphate to the 3' end of the growing strand (while removing pyrophosphate must be removed). In a linear or circular nucleic acid molecule, if a discrete element ( eg, a particular nucleotide sequence) binds to or will bind to the 5' direction of another element on the same nucleic acid, it is said to be located in the other element. Upstream or "5'". Similarly, a discrete element is referred to as being "downstream" or "3'" of the other element if it is conjugated or conjugated to the 3' direction of the other element on the same nucleic acid.

As used herein, base "position" refers to the position of a given base or nucleotide residue within a given nucleic acid. The specified nucleic acid system can be defined by alignment with a reference nucleic acid (see below).

Hybridization relates to the binding of two polynucleotide strands via hydrogen bonds. Oligonucleotides and analogs thereof hybridize by hydrogen bonding between complementary bases, including Watson-Crick, Hoogsteen, or Reverse Hugues hydrogen bonding. In general, the nucleic acid molecule consists of a nitrogenous base which is pyrimidine (cytosine (C), uracil (U) and thymine (T)) or guanidine (adenine (A)). And guanine (G)). These nitrogen-containing bases form a hydrogen bond between pyrimidine and purine, and the bond between pyrimidine and purine is called "base pairing". More specifically, A will be hydrogen bonded to T or U and G will be bonded to C hydrogen. "Complementary" refers to base pairing that occurs between two different nucleic acid sequences or between two different regions of the same nucleic acid sequence.

The terms "specifically hybridizable" and "specifically complementary" indicate a sufficient degree of complementarity to result in a stable and specific binding between an oligonucleotide and a DNA or RNA target. The oligonucleotide need not be 100% complementary to the target sequence to which it can specifically hybridize. Oligonucleotide Binding of a DNA or RNA molecule interferes with the normal function of the target DNA or RNA, and is sufficiently complementary to avoid oligos in the case where specific binding is desired (eg, in vivo or in vivo under physiological conditions) Where the nucleotide non-specifically binds to a non-target sequence, the oligonucleotide is specifically hybridizable. A binding line of this type is referred to as specific hybridization.

Hybridization conditions that result in a particular degree of stringency will vary depending on the nature of the hybridization method chosen and the composition and length of the hybrid nucleic acid sequence. In general, the hybridization temperature and the ionic strength of the hybridization buffer (especially Na+ and/or Mg2+ concentrations) will constitute a stringency of hybridization, although cleaning time will also affect stringency. The calculation of the hybridization conditions required to obtain a particular degree of stringency is in Sambrook et al. (eds.), Molecular Cloning: A Laboratory Manual , 2nd Edition, Vol. 1-3, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York. , 1989, discussed in Chapters 9 and 11.

As used herein, "stringent conditions" encompass conditions in which hybridization occurs only when the mismatch between the hybrid molecule and the DNA target is less than 50%. "Strict conditions" include other specific levels of rigor. Thus, as used herein, "moderately stringent" conditions are those in which a sequence mismatch of more than 50% of the molecules does not hybridize; "high stringency" conditions are those in which the sequence mismatch exceeds 20% of the sequence does not hybridize. The "very high stringency" condition is a condition in which a mismatch of more than 10% of the sequences does not hybridize.

In particular embodiments, stringent conditions can include hybridization at 65 °C followed by a 0.1x SSC/0.1% SDS wash at 65 °C for 40 minutes.

The following are representative, non-limiting hybridization conditions:

Extremely high stringency: 16 hours in 65xC in 5x SSC buffer; 15 times in 2x SSC buffer at room temperature for 15 minutes; and in 65x SSC buffer at 65 °C clear Wash twice, every 20 minutes.

High stringency: 16-20 hours in 65x70x CSC in 5x-6x SSC buffer; 2-20 minutes in 2x SSC buffer at room temperature; and 1x SSC buffer The solution was washed twice at 55-70 ° C for 30 minutes each time.

Medium stringency: Hybridization in 6x SSC buffer at room temperature to 55 °C for 16-20 hours; wash in 2x-3x SSC buffer at room temperature to 55 °C at least twice for 20-30 minutes each.

In particular embodiments, nucleic acid molecules that can specifically hybridize can remain bound under extremely stringent hybridization conditions. In these and other embodiments, nucleic acid molecules that can specifically hybridize can remain bound under conditions of high stringency hybridization. In these and other embodiments, nucleic acid molecules that can specifically hybridize can remain bound under moderately stringent hybridization conditions.

Oligonucleotide: The oligonucleotide is a short nucleic acid polymer. Oligonucleotide lines can be formed by cleavage of longer nucleic acid segments or by polymerization of individual nucleotide precursors. Automated synthesizers allow the synthesis of oligonucleotides of up to several hundred base pairs in length. Since an oligonucleotide can bind to a complementary nucleotide sequence, it can be used as a probe for detecting DNA or RNA. Oligonucleotides (oligodeoxyribonucleotides) composed of DNA can be used in PCR techniques for amplifying small DNA sequences. In PCR, an oligonucleotide is commonly referred to as an "introduction" that allows a DNA polymerase to extend an oligonucleotide and replicate a complementary strand.

As used herein, the terms "sequence identity" or "consistency" (as used in the context of two nucleic acid or polypeptide sequences herein) may refer to when the two sequences are aligned on a specified comparison window. The same residue in both sequences when the maximum correspondence is reached.

As used herein, the term "percent sequence identity" may refer to a value determined by comparing two optimal alignment sequences ( eg, a nucleic acid sequence and an amino acid sequence) on a comparison window, wherein The optimal alignment may include additions or deletions ( ie, gaps) when the sequence portion in the comparison window is compared to the reference sequence (which does not include additions or deletions). The percentage is calculated as follows: the number of positions in which the same nucleic acid or amino acid residue appears in both sequences is determined to produce the number of matching positions, the number of matching positions is divided by the total number of positions in the comparison window, and the result is obtained Multiply by 100 to produce the percent sequence identity.

Methods for comparing aligned sequences are well known in the art. Various programs and alignment algorithms are described, for example, in Smith and Waterman (1981) Adv. Appl. Math. 2:482; Needleman and Wunsch (1970) J. Mol. Biol. 48:443; Pearson and Lipman ( 1988) Proc. Natl. Acad. Sci. USA 85:2444; Higgins and Sharp (1988) Gene 73:237-44; Higgins and Sharp (1989) CABIOS 5:151-3; Corpet et al. (1988) Nucleic Acids Res . 16: 10881-90; Huang et al. (1992) Comp.Appl.Biosci 8:. 155-65 ; Pearson et al. (1994) Methods Mol.Biol 24:. 307-31; Tatiana et al. (1999) FEMS Microbiol .Lett. 174:247-50. Detailed considerations for sequence alignment methods and homology calculations can be found, for example , in Altschul et al. (1990) J. Mol. Biol. 215:403-10.

The National Biotechnology Information Center (NCBI) Base Local Alignment Search Tool ( B asic L ocal A lignment S earch T ool, BLAST ^TM ; Altschul et al. (1990)) is available from several sources, including the National Center for Biotechnology Information. (Bethesda, MD) and the Internet for use with a variety of sequence analysis programs. On how to use this program to determine the consistency of the system described sequences BLAST ^TM of the "Help" section available on the Internet. For the comparison of nucleic acid sequences can be used to perform BLAST ^TM preset parameters of the program "Blast 2 sequences" (Blastn). When evaluated using this method, nucleic acid sequences with greater similarity to the reference sequence will show a higher percent identity.

As used herein, the term "operably linked" relates to when the first nucleic acid sequence When the column is in a functional relationship with the second nucleic acid sequence, the first nucleic acid sequence is operably linked to the second nucleic acid sequence. For example, a promoter is operably linked to a coding sequence when the promoter affects the transcription or expression of the coding sequence. When produced recombinantly, the operably linked nucleic acid sequences are generally contiguous and are located in the same reading frame when it is necessary to join the two protein coding regions. However, the elements need not be contiguous for operative connection.

As used herein, the term "promoter" refers to a region of DNA that is generally upstream of the gene (toward the 5' region of the gene) and that is required for initiation and driving of gene transcription. The promoter can properly activate or inhibit the gene it controls. The promoter may contain a specific sequence that is recognized by the transcription factor. These factors can bind to a promoter DNA sequence, resulting in the addition of RNA polymerase, an enzyme that synthesizes RNA from the coding region of the gene. Promoters generally refer to all gene regulatory elements located upstream of a gene, including an upstream promoter, a 5'-UTR, an intron, and a leader sequence.

As used herein, the term "upstream promoter" refers to a contiguous polynucleotide sequence sufficient to direct the initiation of transcription. As used herein, the upstream promoter encompasses the transcription initiation site and several sequence motifs, including the TATA box, the initiation sequence, the TFIIB recognition element, and other promoter motifs (Jennifer, EF et al ., (2002) Genes. & Dev. , 16:2583-2592). The upstream promoter provides a site of action for RNA polymerase II, which is a multiple secondary unit enzyme, with basic or universal transcription factors such as TFIIA, B, D, E, F, and H. These factors assemble into a pre-transcriptional initiation complex that catalyzes the synthesis of RNA from a DNA template.

Activation of the upstream promoter is carried out by modulating additional sequences of DNA sequence elements, and various protein lines bind to the additional sequences and subsequently interact with the transcription initiation complex to activate gene expression. These gene regulatory element sequences interact with specific DNA binding factors. These sequence primitives are sometimes referred to as cis elements. Tissue-specific or development-specific transcription factors bind such cis- elements individually or in combination such that such cis-elements can determine the spatiotemporal expression pattern of the promoter at the transcriptional level. These cis- elements can vary widely in the type of control of the operably linked genes. Some components increase the transcription of operably linked genes in response to environmental reactions such as temperature, humidity, and trauma. Other cis- elements can respond to developmental signals ( eg, germination, seed maturation and flowering) or to spatial information ( eg, tissue specificity). See, for example, Langridge et al ., (1989) Proc. Natl. Acad. Sci. USA 86:3219-23. These cis- elements differ in distance from the start of transcription, some cis-elements (called near-end elements) are adjacent to a minimal core promoter region, and other elements can be located upstream or downstream of the promoter (enhancer) Thousand base positions.

As used herein, the term "5' non-translated region" or "5'-UTR" is defined as the non-translated segment of the 5' end of the pre-mRNA or mature mRNA. For example, on mature mRNA, the 5'-UTR usually contains a 7-methylguanosine cap on its 5' end and involves many processes, such as splicing, polyadenylation, mRNA export to the cytoplasm, and identification by the translational machinery. The 5' end of the mRNA, as well as protecting the mRNA from degradation.

As used herein, the term "transcription terminator" is defined as the transcriptional segment of the 3' end of the pre-mRNA or mature mRNA. For example, a longer stretched DNA line outside the "polyadenylation signal" site is transcribed as a pre-mRNA. This DNA sequence typically contains a transcription termination signal to properly process the pre-mRNA into mature mRNA.

As used herein, the term "3' non-translated region" or "3'-UTR" is defined as the untranslated segment of the 3' end of the pre-mRNA or mature mRNA. For example, on mature mRNA, this region contains a poly(A) tail and is known to have many effects in mRNA stability, translation initiation, and mRNA export. In addition, the 3'-UTR is considered to contain a polyadenylation signal and a transcription terminator.

As used herein, the term "polyadenylation signal" refers to a nucleic acid sequence present in an mRNA transcript that, when present in the presence of a poly(A) polymerase, allows the transcript to be, for example, located downstream of the poly(A) signal 10 to Polyadenylation at a polyadenylation site at 30 bases. Many polyadenylation signals are known in the art and are suitable for use in the present invention. Exemplary sequences include AAUAAA and variants thereof, as described in Loke J., et al, (2005) Plant Physiology 138(3); 1457-1468.

The "DNA-binding transgene" is a polynucleotide coding sequence encoding a DNA-binding protein. The DNA binding protein can then bind to another molecule. The binding protein can bind to, for example, a DNA molecule (DNA binding protein), an RNA molecule (RNA binding protein), and/or a protein molecule (protein binding protein). In the case of a protein binding protein, it can bind to itself (to form a homodimer, a homotrimer, etc.), and/or it can bind to one or more molecules of a different protein. The binding protein may have more than one type of binding activity. For example, zinc finger proteins have DNA binding, RNA binding, and protein binding activity.

Examples of DNA binding proteins include; meganuclease, zinc finger, CRISPR, and TALE binding domains that can be "engineered" to bind to a predetermined nucleotide sequence. Typically, engineered DNA binding proteins ( eg, zinc fingers, CRISPR or TALE) are non-naturally occurring proteins. Non-limiting examples of methods for engineering DNA binding proteins are by design and selection. The designed DNA binding protein is a protein that is not found in nature, and its design/composition is generally produced by reasonable criteria. Reasonable criteria for design include the application of a replacement rule and a computerized algorithm to process information in the existing ZFP, CRISPR and/or TALE design and combined data repository information. See, for example, U.S. Patent Nos. 6,140, 081, 6, 453, 242, and 6, 534, 261; see also WO 98/53058, WO 98/53059, WO 98/53060, WO 02/016536, and WO 03/016496, and U.S. Patent Publication No. 20110301073, And 20119145940.

A "zinc finger DNA binding protein" (or binding domain) is a protein that binds DNA in a sequence-specific manner via one or more zinc fingers or a domain within a larger protein that is within the binding domain The amino acid sequence region in which the structure is stabilized by zinc ion coordination. The term zinc finger DNA binding protein is often abbreviated as zinc finger protein or ZFP. The zinc finger binding domain can be "engineered" to bind to a predetermined nucleotide sequence. Non-limiting examples of methods for engineering zinc finger proteins are designed and selected. The zinc finger protein is designed to be a protein that is not found in nature, and its design/composition is generally produced by reasonable criteria. Reasonable criteria for design include the application of a replacement rule and a computerized algorithm to process the information in the existing ZFP design and the data stored in the database. See, for example, U.S. Patent Nos. 6,140,081, 6, 453, 242, 6, 534, 261, and 6, 794, 136; see also WO 98/53058, WO 98/53059, WO 98/53060, WO 02/016536, and WO 03/016496.

In other examples, the DNA binding domain of one or more nucleases comprises a naturally occurring or engineered (non-naturally occurring) TAL effector DNA binding domain. See, for example, U.S. Patent Publication No. 20110301073, which is incorporated herein in its entirety by reference. It is known that plant pathogens of the genus Xanthomonas cause many diseases in important crops. The pathogenic pathogen of Xanthomonas is dependent on the conserved type III secretion (T3S) system, which injects more different effector proteins into plant cells. Among these injected proteins are transcription activator-like (TALEN) effectors that mimic plant transcriptional activators and manipulate plant transcriptomes (see Kay et al. (2007) Science 318:648-651). These proteins contain a DNA binding domain and a transcriptional activation domain. One of the most well characterized of the effector is from TAL campestris Xanthomonas campestris pv pepper scab (. Xanthomonas campestgris pv Vesicatoria) of AvrBs3 (see Bonas et al., (1989) Mol Gen Genet 218 : 127-136 and WO2010079430 ). The TAL effector contains a central domain consisting of tandem repeats, each containing about 34 amino acids, which are critical for the DNA binding specificity of these proteins. In addition, it contains a nuclear localization sequence and an acidic transcriptional activation domain (for a review, see Schornack S, et al., (2006) J Plant Physiol 163(3): 256-272). Further, in the phytopathogenic bacteria Ralstonia solanacearum (Ralstonia solanacearum) has been found to brg11 hpx17 the gene is Ralstonia solanacearum (R.solanacearum) biovar strains GMI1000 and two called biovar The X. sphaeroides AvrBs3 family in the strain RS1000 is homologous (see Heuer et al., (2007) Appl and Enviro Micro 73(13): 4379-4384). These genes have 98.9% identical nucleotide sequences to each other with the difference that there is a 1,575 bp deletion in the repeat domain of hpx17. However, the sequence identity of these two gene products with the Xanthomonas AvrBs3 family protein was less than 40%. See, for example, U.S. Patent Publication No. 20110301073, which is incorporated herein in its entirety by reference.

The specificity of these TAL effectors depends on the sequence found in the tandem repeats. This repeat sequence comprises approximately 102 bp and typically has 91-100% homology to each other (Bonas et al., supra ). The polymorphism of the repeat sequence is usually located at positions 12 and 13, and there appears to be a presence between the identity identifier of the hyper-double residue at positions 12 and 13 and the identity of the contiguous nucleotides in the target sequence of the TAL effector. Correspondence to one (see Moscou and Bogdanove, (2009) Science 326: 1501 and Boch et al. (2009) Science 326: 1509-1512). The natural coding of these TAL effectors for DNA recognition has been experimentally determined such that the HD sequences at positions 12 and 13 bind to cytosine (C), NG binds to T, and NI binds to A, C, G or T. , NN binds to A or G, and ING binds to T. These DNA-binding repeats have been assembled to have new combinations of repeats and numbers of proteins, and to create artificial transcription factors capable of interacting with new sequences in plant cells and activating the expression of non-endogenous reporter genes ( Boch et al., ibid .). The engineered TAL protein has been ligated into the Fok I cleavage half-domain to generate a TAL effector domain nuclease fusion (TALEN) that exhibits activity in a yeast reporter assay (a plastid-based target).

CRISPR (clustered, regularly spaced short palindromic repeats) clustered regular interval short palindromic repeats) / CAS (CRISPR related) nuclease system is a recently engineered bacterial system based on genomic engineering Nuclease system. It is based in part on the adaptive immune response of many bacteria and archaea. When a virus or plastid invades a bacterium, the DNA segment of the invader is converted to CRISPR RNA (crRNA) by an "immune" reaction. This crRNA then binds to another type of RNA called tracrRNA by a partially complementary region to direct the Cas9 nuclease to a region known as a "prototype spacer" homologous to the crRNA in the target DNA. Cas9 cleaves DNA at a site specified by a 20-nucleotide leader sequence contained within the crRNA transcript to create a blunt end at the double strand break (DSB). Both cr9 require crRNA and tracrRNA for site-specific DNA recognition and cleavage. This system has now been engineered to allow crRNA and tracrRNA to be combined into one molecule ("single-guided RNA"), and the crRNA equivalent portion of the single-lead RNA can be engineered to direct Cas9 nuclease guidance to any desired Sequence (see Jinek et al ., (2012) Science 337, pp. 816-821; Jinek et al . (2013), eLife 2: e00471 and David Segal, (2013) eLife 2: e00563). Thus, the CRISPR/Cas system can be engineered to form DSBs at the desired targets in the genome and affect the repair of DSBs through the use of repair inhibitors, thereby increasing error-prone repair.

In other examples, the DNA-binding transgenic line is a site-specific nuclease comprising an engineered (non-naturally occurring) meganuclease (also known as a homing endonuclease). Such as I- Sce I, I- Ceu I, PI- Psp I, PI- Sce , I- Sce IV, I- Csm I, I- Pan I, I- Sce II, I- Ppo I, I- Sce III, The recognition sequences of homing endonucleases or meganucleases of I- Cre I, I- Tev I, I- Tev II and I- Tev III are known. See also U.S. Patent No. 5,420,032; U.S. Patent No. 6,833,252; Belfort et al., (1997) Nucleic Acids Res. 25:3379-30 3388; Dujon et al., (1989) Gene 82:115-118; Perler et al. (1994) Nucleic Acids Res. 22, 11127; Jasin (1996) Trends Genet. 12: 224-228; Gimble et al ., (1996) J. Mol. Biol. 263: 163-180; Argast et al., (1998) J. Mol. Biol. 280: 345-353 and New England Biolabs catalog. In addition, the DNA binding specificity of homing endonucleases and meganucleases can be engineered to bind non-natural target sites. See , for example, Chevalier et al, (2002) Molec. Cell 10:895-905; Epinat et al, (2003) Nucleic Acids Res. 5 31:2952-2962; Ashworth et al, (2006) Nature 441:656- 659; Paques et al., (2007) Current Gene Therapy 7: 49-66; U.S. Patent Publication No. 20070117128. Enzymes cut within meganuclease homing nucleic acid DNA binding domain may vary based on the entire nuclease body (i.e., such that homologous nuclease comprises a cleavage domain), or may be fused to a heterologous cleavage domain.

As used herein, the term "transformation" encompasses all techniques by which a nucleic acid molecule can be introduced into a cell of this type. Examples include (but are not limited to): transfection with viral vectors; Transformation with plasmid vectors; electroporation; lipofection; microinjection (Mueller et al., (1978) Cell 15: 579-85 ); Agrobacterium mediated transfer; direct DNA uptake; WHISKERS ^TM mediated shape; and microprojectile bombardment. These techniques can be used for stable transformation and temporary transformation of plant cells. "Stable transformation" refers to the introduction of a nucleic acid fragment into the genome of a host organism resulting in a stable inheritance of the gene. Once stably transformed, the nucleic acid fragments are stably integrated into the genome of the host organism and any progeny. A host organism containing a transduced nucleic acid fragment is referred to as a "transgenic gene" organism. "Temporary transformation" refers to the introduction of a nucleic acid fragment into the nucleus of a host organism or a DNA-containing organelle, resulting in gene expression without genetically stable inheritance.

Exogenous nucleic acid sequence. In one example, the transgenic gene is a gene sequence ( eg, a herbicide tolerance gene), a gene encoding an industrially or pharmaceutically useful compound, or a gene encoding a desired agricultural trait. In another example, the transgenic gene line is an antisense nucleic acid sequence, wherein expression of the antisense nucleic acid sequence inhibits expression of the target nucleic acid sequence. The transgenic gene may contain regulatory sequences ( e.g., promoters) operably linked to the transgenic gene. In some embodiments, the polynucleotide sequence of interest is a transgenic gene. However, in other embodiments, the polynucleotide sequence of interest is an endogenous nucleic acid sequence (wherein an additional genomic copy of the endogenous nucleic acid sequence is desired) or a target relative to the host organism The sequence of the nucleic acid molecule is in the antisense orientation of the nucleic acid sequence.

As used herein, the term gene transfer "event" is produced by transforming a plant cell with a heterologous DNA (ie, a nucleic acid construct comprising a transgene of interest) from which the gene is inserted into the plant. Regeneration of plant populations produced in the genome, as well as selection of a particular plant that is characterized by insertion into a specific genomic location. The term "event" refers to a progeny comprising the original transformant of a heterologous DNA and a transformant. The term "event" also refers to progeny produced by sexual outcrossing between a transformant and another species comprising the genomic/transgenic DNA. Even after repeated backcrossing with the recurrent parent, the transgenic DNA inserted from the transformed parent and the flanking genomic DNA (genomic/transgenic DNA) are still present at the same chromosomal location of the progeny. The term "event" also refers to the original morph and its descendants, which are expected to be transferred to The inserted DNA of the progeny and the flanking genomic sequence immediately adjacent to the inserted DNA, and due to a parental line containing the inserted DNA (eg, the original transform and the progeny produced by selfing) and one not The result of sexual crosses with the parental line containing the inserted DNA, which received the inserted DNA containing the gene of interest.

In general, sequence information from the ends of the region of interest or beyond the ends must be obtained in order to design oligonucleotide primers; these primers will be identical or similar in sequence to the opposite strands on the template to be amplified. The nucleotides at the 5' end of the two primers are identical to the ends of the amplified material. PCR can be used to amplify specific RNA sequences, specific DNA sequences from total genomic DNA, and cDNA transcribed from total cellular RNA, phage or plastid sequences, and the like.

"Non-viral vector" means any vector that does not include a virus or retrovirus. In some embodiments, a "vector" is a DNA sequence comprising at least one DNA origin of replication and at least one selectable marker gene. Examples include, but are not limited to, plastids, vesicles, phages, artificial bacterial chromosomes (BACs) that carry exogenous DNA into cells. The vector may also comprise one or more genes, antisense molecules and/or selection marker genes as well as other genetic elements known in the art. The vector can transduce, transform or infect the cell, thereby allowing the cell to display the nucleic acid molecule and/or protein encoded by the vector. The term "plastid" is defined as a circular stranded nucleic acid capable of autosomal replication in a prokaryotic or eukaryotic host cell. The term encompasses DNA and RNA and And it can be a single stranded strand or a double stranded strand of nucleic acid. The definition of a plastid may also include a sequence corresponding to the origin of bacterial replication.

As used herein, the term "selection marker gene" defines a gene or other expression cassette encoding a protein that facilitates the identification of a cell into which a selection marker gene is inserted. For example, a "selection marker gene" encompasses a reporter gene and a gene for plant transformation to, for example, protect plant cells from selection of agents or provide resistance/tolerance to selected agents. In one embodiment, only those cells or plants that receive a functional selection marker are capable of cleavage or growth under conditions in which the agent is selected.

As used herein, the term "small RNA" refers to various types of non-coding ribonucleic acids (ncRNAs). The term small RNA is a description of short-chain ncRNAs produced in bacterial cells, animals, plants and fungi. These ncRNA short-chain lines can be naturally produced in cells, or can be produced by introduction of a short-chain or ncRNA-derived sequence. Small RNA sequences do not directly encode proteins and are functionally different from other RNAs because small RNA sequences are only transcribed and not translated. Small RNA sequences are involved in other cellular functions, including gene expression and modification. Small RNA molecules typically consist of about 20 to 30 nucleotides. Small RNA sequences can be obtained from longer precursors. The precursor system forms a structure that folds back into each other within the self-complementary region; it is then processed by the nuclease Dicer in the animal or the nuclease DCL1 in the plant.

Many types of small RNAs exist in natural or artificially produced forms, including microRNAs (miRNAs), short interfering RNAs (siRNAs), antisense RNAs, short hairpin RNAs (shRNAs), and small nucleolar RNAs (snoRNAs). Certain types of small RNAs, such as microRNAs and siRNAs, are important in gene silencing and RNA interference (RNAi). Gene silencing is a process of gene regulation in which the gene line that is usually expressed is "closed" by intracellular elements (in this case, small RNA). Proteins that are normally formed by this genetic information are not formed by interference, and the information encoded in the genes is blocked and not expressed.

Plant-preferred codons can be determined from the most frequently occurring codons in the protein with the greatest amount of expression among the particular plant species of interest. In one embodiment, the coding sequence, gene or transgenic gene is designed to be expressed to a greater extent in the plant, resulting in higher transformation efficiency. Methods for optimizing plant genes are well known. Specification for the optimization and generation of synthetic DNA sequences can be found, for example, in the patents WO2013016546, WO2011146524, WO1997013402, U.S. Patent No. 6,166,302, and U.S. Patent No. 5,380,831, incorporated herein by reference.

Transformation

Suitable methods for transforming plants include any method for introducing DNA into cells, such as, but not limited to, electroporation (see, e.g., U.S. Patent No. 5,384,253); microprojectile bombardment (see, for example) U.S. Patent Nos. 5,015,580, 5,550,318, 5,538,880, 6,160, 208, 6, 399, 861 and 6,403, 865; Agrobacterium- mediated transformations (see, for example, U.S. Patent Nos. 5,635,055, 5,824,877, 5,591,616; 5,981,840 and 6,384,301); and protoplast transformation (See, for example, U.S. Patent No. 5,508,184).

The DNA construct can be directly introduced into the genomic DNA of the plant cell using a technique such as stirring with the cerium carbide fiber (see, for example, U.S. Patent Nos. 5,302,523 and 5,464,765), or the DNA construct can be used, such as DNA particle bombardment. The gene gun method is directly introduced into plant tissues (see, for example, Klein et al. (1987) Nature 327: 70-73). Alternatively, the DNA construct can be introduced into the plant cell via transformation of the nanoparticle (see, for example, U.S. Patent Publication No. 20090104700, which is incorporated herein in its entirety by reference).

In addition, gene transfer can be achieved using non- Agrobacterium or virus, such as Rhizobium sp. NGR234, Sinorhizoboium meliloti , Mesorhizobium loti , Potato virus X, broccoli mosaic For virion and cassava vein mosaic virus and/or tobacco mosaic virus, see, for example, Chung et al. (2006) Trends Plant Sci. 11(1):1-4.

By the application of the transformation technique, cells of almost any plant species can be stably transformed, and these cells can be developed into gene-transforming plants by well-known techniques. For example, a particular case of a prior art system is Transformation of cotton described in U.S. Patent Nos. 5,846,797,5,159,135,5,004,863 and 6,624,344; and in particular a Brassica Transformation of Plant Technology described in (e.g.) in U.S. Patent No. 5,750,871 The technique for the transformation of soybeans is described in, for example, U.S. Patent No. 6,384,301; the disclosure of U.S. Patent Nos. 7,060,876 and 5,591,616, and the International PCT Publication No. WO 95 In /06722.

After delivery of the exogenous nucleic acid to the recipient cell, the transformed cell is typically identified for further culture and plant regeneration. In order to improve the ability to identify transformants, it may be desirable to employ a selectable marker gene and a transforming vector for producing the transformant. In an illustrative embodiment, the transformed population of cells can be assayed by exposing the cells to one or more selection agents, or the cells can be screened for the desired marker gene trait.

The cells that survive the exposure to the selected agent, or the cells that are assessed to be positive in the screening assay, can be cultured in a medium that supports plant regeneration. In one embodiment, any suitable plant tissue culture medium can be modified by the inclusion of other materials such as growth regulating nodules. The tissue can be maintained on a basal medium with a growth regulator until sufficient tissue is available for starting the plant regeneration, or after repeated rounds of manual selection until the morphology of the tissue is suitable for regeneration (eg, at least 2 Week), then transferred to a medium that aids in bud formation. The culture is transferred periodically until sufficient shoot formation has occurred. Once the shoots are formed, they are transferred to a medium that facilitates root formation. Once sufficient roots are formed, the plants are transferred to the soil for further growth and maturation.

Molecular confirmation

The transformed plant cell, healing tissue, tissue or plant line can be identified and isolated by selecting or screening for the engineered plant material for the trait encoded by the marker gene present on the transgeneic DNA. For example, the engineered plant material can be selected by culturing the engineered plant material on a medium containing an inhibitory amount of an antibiotic or herbicide that confers resistance to the antibiotic or herbicide. Alternatively, the transformed can be identified by screening for activity of any visible marker gene ( eg , beta-glucuronidase, luciferase or gfp gene) that may be present on the recombinant nucleic acid construct . Plants and plant cells. Such selection and screening methods are well known to those skilled in the art. Molecular confirmation methods that can be used to identify genetically transgenic plants are known to those skilled in the art. Several illustrative methods are described further below.

Molecular beacons have been discovered for use in sequence detection. Briefly, a FRET oligonucleotide probe was designed to overlap with the flanking genome and the insert DNA junction. The unique structure of the FRET probe is such that it contains a secondary structure that maintains a close proximity of the fluorescent moiety and the quenching moiety. The FRET probe and PCR primer (one primer in the inserted DNA sequence and one primer in the flanking genomic sequence) are circulated in the presence of a thermostable polymerase and dNTP. After successful PCR amplification of the cycled, the hybridization of the FRET probe to the target sequence results in removal of the probe secondary structure and spatial separation of the fluorescent moiety from the quenching moiety. Fluorescent signals indicate flanking genomic/transgenic gene insertion sequences that are present due to successful amplification and hybridization. Such molecular beacon assays for detection in the form of amplification reactions are an embodiment of the invention.

The FRET probe and PCR primer (one primer in the inserted DNA sequence and one primer in the flanking genomic sequence) are circulated in the presence of a thermostable polymerase and dNTP. Hybridization of the FRET probe results in cleavage and release of the fluorescent moiety on the FRET probe leaving the quenching moiety. Fluorescent signals indicate flanking/transgenic gene insertion sequences that are present due to successful amplification and hybridization. Such a hydrolysis probe assay for detection in the form of an amplification reaction is an embodiment of the invention.

In an embodiment SYTO13 ^®, a second fluorescent dye-based DNA is less than 10 M, less than or less than 2.7μM used 4μM embodiment.

In other embodiments, next generation sequencing (NGS) techniques can be used for detection. As described by Brautigma et al. in 2010, DNA sequence analysis can be used to determine the nucleotide sequence of the isolated and amplified fragments. The amplified fragments can be isolated and re-selected into a vector and sequenced using a chain terminator method (also known as Sanger sequencing) or dye terminator sequencing. In addition, the amplification lines can be sequenced using next generation sequencing techniques. NGS technology does not require a re-sequence step and multiple sequencing reads can be performed in a single reaction. Three NGS platforms are commercially available, namely Genome Sequencer FLX ^(TM) from 454 Life Sciences/Roche, Illumina Genome Analyser ^(TM) from Solexa, and SOLiD ^{(TM) from} Applied Biosystems ("Sequencing by Oligo Ligation and Detection" Abbreviation for acid ligation and detection method sequencing). In addition, there are two single-molecule sequencing methods currently under development. These methods include true Single Molecule Sequencing from Helicos Bioscience ^TM's (tSMS, true single molecule sequencing) and Single Molecule Real Time ^TM sequencing from Pacific Biosciences of (SMRT, single molecule real-time DNA sequencing).

The Genome Sequencher FLX ^(TM) , marketed by 454 Life Sciences/Roche, is a long-read NGS that uses emulsification PCR and pyrophosphate sequencing to generate sequencing reads. A DNA fragment of 300-800 bp or a gene bank containing a 3-20 kb fragment can be used. For a total yield of 250 to 400 megabases, these reactions can produce more than one million reads of about 250 to 400 bases per run. This technique produces the longest read sequence, but the total sequence output per run is lower compared to other NGS techniques.

The Illumina Genome Analyser ^{( TM)} , marketed by Solexa ^{(TM )} , is a short-read NGS whose sequencing is based on solid-phase bridged PCR by a synthetic method using a reversible termination nucleotide labeled with a fluorescent dye. A double-end sequencing gene bank construct containing a DNA fragment of up to 10 kb can be used. These reactions result in more than one hundred million short read fragments of 35-76 bases in length. This data can produce between 3 and 6 billion bases per run.

Sold by ^{Applied Biosystems TM Sequencing by Oligo Ligation and} Detection (SOLiD) based system as a short-read sequencing techniques. This NGS technique uses fragmented double strand DNA of up to 10 kb in length. The system performs sequencing by conjugating dye-labeled oligonucleotide primers and emulsification PCR to generate one billion short-reading fragments, each generating up to a total sequence output of up to 30 billion bases.

Different Helicos Bioscience ^TM of the Pacific Biosciences ^TM tSMS and SMRT-based application mode, a single DNA molecules using the reaction sequence. tSMS Helicos ^TM system per run generate up to 800 million short sequence reads obtained fragment 21 billion bases. These reactions are performed using fluorescent dye-labeled virtual terminating nucleotides, which are referred to as "synthesized sequencing" methods.

SMRT next-generation sequencing-based systems sold by Pacific Biosciences ^TM instant sequencing by synthesis. This technique produces up to 1,000 bp long reads due to the limitations of reversible terminators. Using this technique, an original read flux equivalent to one-fold coverage of the diploid human genome is produced each day.

In another embodiment, the detection can be performed using dot measurement, including the Western dot method, the northern dot method, and the Southern dot method. Such dot assays are commonly used techniques for the identification and quantification of biological samples in biological research. These assays involve first separating the sample components in the gel by electrophoresis, followed by transferring the electrophoretic separation components from the gel to a transfer film made of a material such as nitrocellulose, polyvinylidene fluoride or nylon. on. The analyte can also be spotted directly onto these loads or directed to a specific area on the load by applying vacuum, capillary action or pressure without prior separation. The transfer film is then typically subjected to post-transfer processing to enhance the ability of the analyte to distinguish and detect from each other visually or by an automated reader.

In another embodiment, detection can be accomplished using an ELISA assay that uses solid phase enzyme immunoassays to detect the presence of a substance (usually an antigen) in a liquid sample or a wet sample. The antigen from the sample is attached to a flat disk surface. Next, another specific antibody is administered on the surface to allow it to bind to the antigen. The anti-system is linked to an enzyme and, in the final step, a substance containing the enzyme is added. Subsequent reactions produce a detectable signal, most often a color change in the receptor.

Gene-specific downstream polynucleotide sequences termed 3' non-translated regions (3' UTR) are generally versatile in vivo . Processing and maturation of RNA Post-transcriptional control of eukaryotic gene expression has been recognized as a key control point (Szostak and Gebauer, 2012; Wilusz and Spector, 2010; Barrett et al., 2012; and Moore, 2005). These polynucleotide sequences can affect nuclear export, intracellular location, transcriptional stability, and rate of translation. In addition, the 3'UTR is a key target site for RNA controlled by small fragments of non-coding. Although these mechanisms down regulate gene expression, such regulation can also be used to efficiently localize transcripts to specific cell types for stable accumulation and subsequent gene expression (Patel et al., 2006).
