Description

Transgenic maize event LP007-2 and methods of detecting same

Technical Field

The invention belongs to the technical field of molecular biology, and relates to a transgenic plant and a detection method of a product thereof, in particular to a transgenic corn event LP007-2 which is resistant to insects and tolerant to application of glyphosate herbicide, a nucleic acid sequence and a method for detecting the transgenic corn LP 007-2.

Background

Corn (Zea mays L.) is a major food crop in many parts of the world. Biotechnology has been applied to corn to improve its agronomic traits and quality. Insect resistance is an important agronomic trait in corn production, particularly resistance to lepidopteran insects (e.g., corn borer, cotton bollworm, spodoptera frugiperda, armyworm, and the like). The lepidopteran resistance of corn can be obtained by expressing a lepidopteran resistance gene in a corn plant by a transgenic method. Another agronomic trait of interest is herbicide tolerance, particularly tolerance to glyphosate herbicide. Tolerance to glyphosate herbicide in corn can be achieved by transgenic methods that express a glyphosate herbicide tolerant gene (e.g., epsps) in the corn plant.

It is known that expression of foreign genes in plants is influenced by their chromosomal location, possibly due to chromatin structure (e.g., heterochromatin) or the proximity of transcriptional regulatory elements (e.g., enhancers) to the integration site. For this reason, it is often necessary to screen a large number of events in order to be able to identify a commercializable event (i.e., an event in which the introduced gene of interest is optimally expressed). For example, it has been observed in plants and other organisms that the amount of expression of an introduced gene may vary greatly between events; differences in the spatial or temporal pattern of expression may also exist, such as differences in the relative expression of the transgene between different plant tissues, in that the actual expression pattern may not be consistent with the expected expression pattern of the transcriptional regulatory elements in the introduced gene construct. Thus, it is often necessary to generate hundreds to thousands of different events and to screen those events for a single event with the amount and pattern of transgene expression expected for commercial purposes. Such transformation events have excellent lepidopteran pest (e.g., asian corn borer, spodoptera frugiperda, oriental armyworm, spodoptera frugiperda, cotton bollworm, black cutworm, dichocrocis punctiferalis, etc.) and glyphosate herbicide resistance without affecting corn yield, and can be used to backcross transgenes into other genetic backgrounds by hybridization using conventional breeding methods. The progeny produced by this crossing retain the transgenic expression characteristics and trait performance of the original transformants. The strategy mode can ensure reliable gene expression in a plurality of varieties, has stable lepidoptera pest resistance (such as Asian corn borer, Spodoptera frugiperda, oriental armyworm, Spodoptera frugiperda, cotton bollworm, black cutworm, dichocrocis punctiferalis and the like) and glyphosate herbicide resistance, prevents the varieties from being harmed by main lepidoptera pests, has broad-spectrum weed control capability, and can well adapt to local growth conditions.

It would be beneficial to be able to detect the presence of particular events to determine whether progeny of a sexual cross contain a gene of interest. In addition, methods for detecting specific events will also help to comply with relevant regulations, such as the need for food derived from recombinant crops to be officially approved and labeled prior to introduction to the market. It is possible to detect the presence of a transgene by any well-known polynucleotide detection method, such as Polymerase Chain Reaction (PCR) or DNA hybridization using a polynucleotide probe. These detection methods usually focus on commonly used genetic elements such as promoters, terminators, marker genes, and the like. Thus, unless the sequence of chromosomal DNA adjacent to the inserted transgenic DNA ("flanking DNA") is known, this method described above cannot be used to distinguish between different events, particularly those produced with the same DNA construct. Therefore, it is now common to identify specific events of a transgene by PCR using a pair of primers spanning the junction of the inserted transgene and flanking DNA, specifically a first primer comprising the flanking sequence and a second primer comprising the inserted sequence.

The "corn" refers to maize (Zea mays) and includes all plant species that can be mated with corn, including wild corn species.

The term "comprising" means "including but not limited to". The term "processed product" refers to a product obtained by processing a raw material such as a plant or a seed, for example, a composition.

The term "plant" includes whole plants, plant cells, plant organs, plant protoplasts, plant cell tissue cultures from which plants can be regenerated, plant calli, plant clumps (plant cylinders), and plant cells that are intact in plants or plant parts, such as embryos, pollen, ovules, seeds, leaves, flowers, branches, fruits, stalks, roots, root tips, anthers, and the like. It is to be understood that parts of transgenic plants within the scope of the present invention, which are derived from transgenic plants or progeny thereof which have been previously transformed with a DNA molecule of the invention and thus consist at least in part of transgenic cells, include, but are not limited to, plant cells, protoplasts, tissue, callus, embryos, and flowers, stems, fruits, leaves, and roots.

The term "gene" refers to a nucleic acid fragment that expresses a particular protein, including regulatory sequences preceding the coding sequence (5 'non-coding sequences) and regulatory sequences following the coding sequence (3' non-coding sequences). "native gene" refers to a gene that is naturally found to have its own regulatory sequences. "chimeric gene" refers to any gene that is not a native gene, comprising regulatory and coding sequences not found in nature. "endogenous gene" refers to a native gene that is located in its natural location in the genome of an organism. A "foreign gene" is a foreign gene that is present in the genome of an organism and that is not originally present, and also refers to a gene that has been introduced into a recipient cell by a transgenic procedure. The foreign gene may comprise a native gene or a chimeric gene inserted into a non-native organism. A "transgene" is a gene that has been introduced into the genome by a transformation procedure. The site in the plant genome at which the recombinant DNA has been inserted may be referred to as an "insertion site" or "target site".

"flanking DNA" may comprise the genome as it occurs naturally in an organism such as a plant or foreign (heterologous) DNA introduced by the transformation process, such as a fragment associated with the transformation event. Thus, flanking DNA may include a combination of native and foreign DNA. In the present invention, a "flanking region" or "flanking sequence" or "genomic boundary region" or "genomic boundary sequence" refers to a sequence of at least 3, 5, 10, 11, 15, 20, 50, 100, 200, 300, 400, 1000, 1500, 2000, 2500, or 5000 base pairs or more in length, which is located directly upstream or downstream of and adjacent to the originally exogenously inserted DNA molecule.

Transformation procedures that result in random integration of the exogenous DNA will result in transformants that contain different flanking regions that are specifically contained by each transformant. When the recombinant DNA is introduced into a plant by conventional crossing, its flanking regions are not usually altered. Transformants will also contain unique junctions between the heterologous insert DNA and segments of genomic DNA or between two segments of heterologous DNA. "junction" is the point at which two specific DNA fragments are joined. For example, the junction is present where the insert DNA joins the flanking DNA. A junction point is also present in a transformed organism where two DNA fragments are joined together in a manner that is modified in the way found in the native organism. "junction DNA" refers to DNA comprising a junction site.

The fourth expression cassette comprises a suitable promoter for expression in a plant operably linked to a gene encoding 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) and a suitable polyadenylation signal sequence, the nucleic acid sequence of the EPSPS protein being tolerant to glyphosate herbicide. Further, the promoter may be a suitable promoter isolated from a plant, including constitutive, inducible and/or tissue specific promoters, suitable promoters include, but are not limited to, the cauliflower mosaic virus (CaMV)35S promoter, the Figwort Mosaic Virus (FMV)35S promoter, the Ubiquitin protein (Ubiquitin) promoter, the Actin (Actin) promoter, the Agrobacterium tumefaciens (Agrobacterium tumefaciens) nopaline synthase (NOS) promoter, the octopine synthase (OCS) promoter, the nocturnal (Cestrum) yellow leaf curly virus promoter, the potato tuber storage protein (Patatin) promoter, the ribulose-1, 5-bisphosphate carboxylase/oxygenase (RuBisCO) promoter, the glutathione thiotransferase (GST) promoter, the E9 promoter, the GOS promoter, the alcA/alcR promoter, the Agrobacterium rhizogenes (Agrobacterium rhizogenes) RolD promoter, and the Arabidopsis thaliana (Arabidopsis thaliana) Suc2 promoter. The polyadenylation signal sequence may be a suitable polyadenylation signal sequence that functions in plants, including, but not limited to, polyadenylation signal sequence derived from the Agrobacterium tumefaciens nopaline synthase (NOS) gene, cauliflower mosaic virus (CaMV)35S terminator, polyadenylation signal sequence derived from the protease inhibitor II (PIN II) gene, and polyadenylation signal sequence derived from the alpha-tubulin (alpha-tubulin) gene.

In addition, the expression cassette may also include other genetic elements including, but not limited to, enhancers and signal peptide/transit peptide nucleic acid coding sequences. The enhancer may enhance the expression level of a gene, including, but not limited to, Tobacco Etch Virus (TEV) translational activator, CaMV35S enhancer, and FMV35S enhancer. The signal peptide/transit peptide may direct the transport of the Cry1Ab protein and/or EPSPS protein to a particular organelle or compartment outside or within the cell, e.g., targeting the chloroplast using a sequence encoding a chloroplast transit peptide, or targeting the endoplasmic reticulum using a 'KDEL' retention sequence.

The Cry1Ab, Cry2Ab and Vip3Aa genes can be obtained by separating from Bacillus thuringiensis (Bt for short), and the nucleic acid sequences of Cry1Ab, Cry2Ab and Vip3Aa genes can be changed by optimizing codons or in other ways, so that the purpose of increasing the stability and the availability of transcripts in transformed cells is achieved.

In some embodiments of the invention, a maize cell, seed or plant comprising transgenic maize event LP007-2 comprises in its genome the nucleic acid sequence of SEQ ID NO 1, SEQ ID NO 5, position 1530-17132 and SEQ ID NO 2, in that order, or comprises SEQ ID NO 5.

The Lepidoptera, the academic name Lepidoptera, comprises two kinds of insects, namely moths and butterflies, and is the most one of the insects in agriculture and forestry, such as corn borers, cotton bollworms, oriental armyworms, Spodoptera frugiperda, Athetis lepigone, dichocrocis punctifera and the like.

The 5-enol-pyruvylshikimate-3-phosphate synthase (EPSPS) gene may be isolated from Agrobacterium tumefaciens (Agrobacterium tumefaciens sp.) CP4 strain, and the polynucleotide encoding the EPSPS gene may be altered by codon optimization or in other ways to increase the stability and availability of the transcript in the transformed cell. The 5-enol-pyruvylshikimate-3-phosphate synthase (EPSPS) gene can also be used as a selectable marker gene.

By "glyphosate" is meant N-phosphonomethylglycine and its salts and by "treatment with glyphosate herbicide" is meant treatment with any herbicide formulation containing glyphosate. The rate of use of a particular glyphosate formulation to achieve an effective biological dose is not chosen beyond the skill of the ordinary agronomic artisan. Treatment of a field containing plant material derived from transgenic corn event LP007-2 with any one of the glyphosate containing herbicide formulations will control weed growth in the field and not affect the growth or yield of plant material derived from transgenic corn event LP 007-2.

The DNA construct is introduced into a plant using transformation methods including, but not limited to, Agrobacterium-mediated transformation, biolistic transformation, and pollen tube channel transformation.

The Agrobacterium-mediated transformation method is a commonly used method for plant transformation. The foreign DNA to be introduced into the plant is cloned between the left and right border consensus sequences of the vector, i.e.the T-DNA region. The vector is transformed into an agrobacterium cell, which is then used to infect plant tissue, and the T-DNA region of the vector comprising the foreign DNA is inserted into the plant genome.

The particle gun transformation method is to bombard plant cells with vectors containing exogenous DNA (particle-mediated biolistic transformation).

The pollen tube channel transformation method is characterized in that a natural pollen tube channel (also called a pollen tube guide tissue) formed after plant pollination is utilized, and exogenous DNA is carried into an embryo sac through a nucellar channel.

After transformation, transgenic plants must be regenerated from the transformed plant tissue and progeny with foreign DNA selected using appropriate markers.

A DNA construct is a combination of DNA molecules linked together to provide one or more expression cassettes. The DNA construct is in particular a plasmid which is capable of autonomous replication in bacterial cells and which contains various restriction sites for the introduction of DNA molecules providing functional genetic elements, i.e.promoters, introns, leaders, coding sequences, 3' terminator regions and other sequences. The expression cassette contained in the DNA construct, which includes the genetic elements necessary to provide for transcription of messenger RNA, can be designed for expression in prokaryotic or eukaryotic cells. The expression cassettes of the invention are designed to be most specifically expressed in plant cells.

A transgenic "event" is obtained by transforming a plant cell with a heterologous DNA construct, i.e., comprising at least one nucleic acid expression cassette containing a gene of interest, inserting into the plant genome by transgenic means to produce a plant population, regenerating said plant population, and selecting a specific plant characterized by the insertion of a specific genomic locus. The term "event" refers to both the original transformant comprising the heterologous DNA and progeny of the transformant. The term "event" also refers to progeny resulting from sexual crosses between a transformant and individuals of other varieties containing heterologous DNA, even after repeated backcrossing with the backcross parent, where the inserted DNA and flanking genomic DNA from the transformant parent are present at the same chromosomal location in the progeny of the cross. The term "event" also refers to a DNA sequence from an original transformant that comprises the inserted DNA and flanking genomic sequences immediately adjacent to the inserted DNA, which DNA sequence is expected to be transferred to progeny that result from sexual crossing of a parent line containing the inserted DNA (e.g., the original transformant and progeny resulting from selfing thereof) with a parent line that does not contain the inserted DNA, and which progeny has received the inserted DNA comprising the gene of interest.

"recombinant" in the context of the present invention refers to a form of DNA and/or protein and/or organism that is not normally found in nature and is therefore produced by human intervention. Such manual intervention may result in recombinant DNA molecules and/or recombinant plants. Such "recombinant DNA molecules" are obtained by artificially combining two otherwise isolated sequence segments, e.g., by chemical synthesis or by manipulating isolated nucleic acid segments by genetic engineering techniques. Techniques for performing nucleic acid manipulations are well known.

The term "transgene" includes any cell, cell line, callus, tissue, plant part or plant, the genotype of which is altered by the presence of heterologous nucleic acid, including the transgene originally so altered and progeny individuals generated from the original transgene by sexual crossing or asexual reproduction. In the present invention, the term "transgene" does not include changes (chromosomal or extra-chromosomal) in the genome by conventional plant breeding methods or naturally occurring events such as random allofertilization, non-recombinant viral infection, non-recombinant bacterial transformation, non-recombinant transposition, or spontaneous mutation.

By "heterologous" in the context of the present invention is meant that the first molecule is not normally found in combination with the second molecule in nature. For example, a molecule may be derived from a first species and inserted into the genome of a second species. Such molecules are therefore heterologous to the host and are artificially introduced into the genome of the host cell.

Culturing transgenic corn event LP007-2 resistant to lepidopteran insects and tolerant to glyphosate herbicide can be accomplished by the steps of: first sexually crossing a first parent corn plant consisting of a corn plant grown from transgenic corn event LP007-2 and its progeny, said transgenic corn event LP007-2 and its progeny resulting from transformation with the lepidopteran insect-resistant glyphosate herbicide-tolerant expression cassette of the present invention, with a second parent corn plant lacking lepidopteran insect resistance and/or glyphosate herbicide tolerance, to produce a plurality of first generation progeny plants; progeny plants that are resistant to lepidopteran insect infestation and/or tolerant to glyphosate herbicide are then selected, and corn plants that are resistant to lepidopteran insects and tolerant to glyphosate herbicide can be grown. These steps can further include backcrossing the lepidopteran insect-resistant and/or glyphosate-tolerant progeny plants with the second or third parent corn plant, and then selecting the progeny by infestation with the lepidopteran insect, application of a glyphosate herbicide, or by identification of a trait-related molecular marker (e.g., a DNA molecule comprising a junction site identified by the 5 'end and the 3' end of the insertion sequence in transgenic corn event LP 007-2), thereby producing a corn plant that is resistant to lepidopteran insects and tolerant to the glyphosate herbicide.

It is also understood that two different transgenic plants may also be crossed to produce progeny containing two separate, separately added exogenous genes. Selfing of appropriate progeny can yield progeny plants that are homozygous for both added exogenous genes. Backcrossing of parental plants and outcrossing with non-transgenic plants as described above is also contemplated, as is asexual propagation.

The term "probe" is an isolated nucleic acid molecule to which a conventional detectable label or reporter molecule, such as a radioisotope, ligand, chemiluminescent agent or enzyme, has been attached. Such a probe is complementary to one strand of the target nucleic acid, and in the present invention, the probe is complementary to one strand of DNA from the genome of transgenic corn event LP007-2, whether the genomic DNA is from transgenic corn event LP007-2 or a seed or plant or seed or extract derived from transgenic corn event LP 007-2. Probes of the invention include not only deoxyribonucleic or ribonucleic acids, but also polyamides and other probe materials that specifically bind to a target DNA sequence and can be used to detect the presence of the target DNA sequence.

The term "primer" is an isolated nucleic acid molecule that binds to a complementary target DNA strand by nucleic acid hybridization, annealing, forming a hybrid between the primer and the target DNA strand, and then extending along the target DNA strand under the action of a polymerase (e.g., a DNA polymerase). The primer pairs of the present invention are directed to their use in amplification of a target nucleic acid sequence, for example, by Polymerase Chain Reaction (PCR) or other conventional nucleic acid amplification methods.

Methods of designing and using primers and probes are well known in the art. DNA molecules comprising full length or fragments of SEQ ID NOS: 1-7 are useful as primers and probes for detecting maize event LP007-2 and can be readily designed by one skilled in the art using the sequences provided herein.

The length of the probes and primers is generally 11 polynucleotides or more, preferably 18 polynucleotides or more, more preferably 24 polynucleotides or more, and most preferably 30 polynucleotides or more. Such probes and primers specifically hybridize to the target sequence under highly stringent hybridization conditions. Although probes that are different from and maintain the ability to hybridize to the target DNA sequence can be designed by conventional methods, it is preferred that the probes and primers of the present invention have complete DNA sequence identity to the contiguous nucleic acid of the target sequence.

Primers and probes based on the flanking genomic DNA and insertion sequences of the present invention can be determined by conventional methods, for example, by isolating the corresponding DNA molecule from plant material derived from transgenic maize event LP007-2 and determining the nucleic acid sequence of the DNA molecule. The DNA molecule comprises a transgene insert and a maize genomic flanking region, and fragments of the DNA molecule can be used as primers or probes.

The nucleic acid probes and primers of the invention hybridize to a target DNA sequence under stringent conditions. Any conventional nucleic acid hybridization or amplification method can be used to identify the presence of DNA derived from transgenic maize event LP007-2 in a sample. Nucleic acid molecules or fragments thereof are in certain cases capable of specific hybridization with other nucleic acid molecules. As used herein, two nucleic acid molecules can be said to be capable of specifically hybridizing to each other if they are capable of forming an antiparallel, double-stranded nucleic acid structure. Two nucleic acid molecules are said to be "complements" of one another if they exhibit complete complementarity. As used herein, a nucleic acid molecule is said to exhibit "perfect complementarity" when each nucleotide of the nucleic acid molecule is complementary to the corresponding nucleotide of another nucleic acid molecule. Two nucleic acid molecules are said to be "minimally complementary" if they are capable of hybridizing to each other with sufficient stability such that they anneal and bind to each other under at least conventional "low stringency" conditions. Similarly, two nucleic acid molecules are said to have "complementarity" if they are capable of hybridizing to each other with sufficient stability to allow them to anneal and bind to each other under conventional "highly stringent" conditions. Deviations from perfect complementarity may be tolerated as long as such deviations do not completely prevent the two molecules from forming a double-stranded structure. In order to allow a nucleic acid molecule to act as a primer or probe, it is only necessary to ensure sufficient complementarity in the sequence to allow the formation of a stable double-stranded structure in the particular solvent and salt concentrations employed.

As used herein, a substantially homologous sequence is a nucleic acid molecule that specifically hybridizes under highly stringent conditions to the complementary strand of a matched nucleic acid molecule. Suitable stringency conditions for promoting DNA hybridization include, for example, treatment with 6.0 XSSC/sodium citrate (SSC) at about 45 ℃ followed by a wash with 2.0 XSSC at 50 ℃, as is well known to those skilled in the art. For example, the salt concentration in the washing step can be selected from the group consisting of about 2.0 XSSC for low stringency conditions, 50 ℃ to about 0.2 XSSC for high stringency conditions, 50 ℃. In addition, the temperature conditions in the washing step can be raised from about 22 ℃ at room temperature for low stringency conditions to about 65 ℃ for high stringency conditions. Both the temperature conditions and the salt concentration may be varied, or one may be held constant while the other is varied. In particular, a nucleic acid molecule of the invention can specifically hybridize to one or more of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 4, SEQ ID NO 5, SEQ ID NO 6 and SEQ ID NO 7, or complements thereof, or any fragment thereof, under moderately stringent conditions, such as at about 2.0 XSSC and about 65 ℃. More specifically, a nucleic acid molecule of the invention specifically hybridizes under highly stringent conditions to one or more of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 4, SEQ ID NO 5, SEQ ID NO 6 and SEQ ID NO 7, or a complement thereof, or any fragment thereof. In the context of the present invention, preferred marker nucleic acid molecules have SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 6 or SEQ ID NO 7 or the complement thereof or any fragment of the aforementioned sequences. Another preferred marker nucleic acid molecule of the invention has 80% to 100% or 90% to 100% sequence identity with SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 6 or SEQ ID NO 7 or the complement thereof or any fragment thereof. SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 6 and SEQ ID NO 7 can be used as markers in plant breeding methods to identify progeny of a genetic cross. Hybridization of the probe to the target DNA molecule can be detected by any method known to those skilled in the art, including, but not limited to, fluorescent, radioactive, antibody-based, and chemiluminescent labels.

With respect to amplification of a target nucleic acid sequence using a particular amplification primer (e.g., by PCR), "stringent conditions" refer to conditions that allow only hybridization of the primer to the target nucleic acid sequence in a DNA thermal amplification reaction, with a primer having a wild-type sequence (or its complement) corresponding to the target nucleic acid sequence that is capable of binding to the target nucleic acid sequence and preferably producing a unique amplification product, i.e., an amplicon.

The term "specifically binds (target sequence)" means that the probe or primer hybridizes under stringent hybridization conditions only to the target sequence in a sample containing the target sequence.

As used herein, "amplified DNA," "amplification product," or "amplicon" refers to the nucleic acid amplification product of a target nucleic acid sequence that is part of a nucleic acid template. For example, to determine whether a corn plant was produced by sexual hybridization comprising the transgenic corn event LP007-2 of the present invention, or whether a corn sample collected from a field comprised the transgenic corn event LP007-2, or whether a corn extract, such as meal, flour, or oil, comprised the transgenic corn event LP007-2, DNA extracted from a corn plant tissue sample or extract can be subjected to a nucleic acid amplification method using a primer pair to produce an amplicon diagnostic for the presence of DNA of the transgenic corn event LP 007-2. The primer pair includes a first primer derived from a flanking sequence adjacent to the insertion site of the inserted foreign DNA in the plant genome, and a second primer derived from the inserted foreign DNA. The amplicon has a length and sequence that is also diagnostic for the transgenic maize event LP 007-2. The amplicon may range in length from the combined length of the primer pair plus one nucleotide base pair, preferably plus about fifty nucleotide base pairs, more preferably plus about two hundred fifty nucleotide base pairs, and most preferably plus about four hundred fifty nucleotide base pairs or more.

Alternatively, primer pairs may be derived from flanking genomic sequences flanking the inserted DNA to produce amplicons that include the entire inserted nucleic acid sequence. One of the primer pairs derived from a plant genomic sequence may be located at a distance from the inserted DNA sequence that may range from one nucleotide base pair to about twenty thousand nucleotide base pairs. The use of the term "amplicon" specifically excludes primer dimers formed in the DNA thermal amplification reaction.

The nucleic acid amplification reaction may be carried out by any of the nucleic acid amplification reaction methods known in the art, including the Polymerase Chain Reaction (PCR). Various nucleic acid amplification methods are well known to those skilled in the art. The PCR amplification method has been developed to amplify 22kb of genomic DNA and 42kb of phage DNA. These methods, as well as other DNA amplification methods known in the art, can be used in the present invention. The inserted exogenous DNA sequence and flanking DNA sequences from transgenic corn event LP007-2 can be amplified by using the provided primer sequences to the genome of transgenic corn event LP007-2, followed by standard DNA sequencing of the PCR amplicons or cloned DNA.

DNA detection kits based on DNA amplification methods may contain DNA primer molecules that specifically hybridize to the target DNA and amplify the diagnostic amplicon under appropriate reaction conditions. The kit may provide an agarose gel based detection method or a number of methods known in the art for detecting diagnostic amplicons. Kits containing DNA primers homologous or complementary to any portion of the maize genomic region of SEQ ID NO 3 or SEQ ID NO 4, and to any portion of the transgene insert region of SEQ ID NO 5 are provided by the present invention. In particular, the primer pairs identified as useful in the DNA amplification method are SEQ ID NO 8 and SEQ ID NO 9, which amplify a diagnostic amplicon homologous to a portion of the 5' transgene/genomic region of transgenic maize event LP007-2, wherein the amplicon comprises SEQ ID NO 1. Other DNA molecules used as DNA primers may be selected from SEQ ID NO 5.

Amplicons produced by these methods can be detected by a variety of techniques. One such method is Genetic Bit Analysis, which designs a DNA oligonucleotide strand spanning an intervening DNA sequence and adjacent flanking genomic DNA sequences. The oligonucleotide strand is immobilized within a microwell of a microwell plate, and after PCR amplification of the target region (using one primer in each of the intervening sequence and adjacent flanking genomic sequence), the single-stranded PCR product can hybridize to the immobilized oligonucleotide strand and serve as a template for a single-base extension reaction using DNA polymerase and ddNTPs specifically labeled for the next desired base. The results can be obtained by fluorescence or ELISA-like methods. The signal represents the presence of the inserted/flanking sequence, indicating that the amplification, hybridization and single base extension reactions were successful.

Another method is Pyrosequencing (Pyrosequencing) technology. The method designs an oligonucleotide strand that spans the junction of the inserted DNA sequence and the adjacent genomic DNA. The oligonucleotide strand is hybridized to the single-stranded PCR product of the target region (using one primer in each of the intervening and adjacent flanking genomic sequences) and then incubated with DNA polymerase, ATP, sulfuryl enzyme, luciferase, apyrase, adenosine-5' -phosphate sulfate, and luciferin. dNTPs were added separately and the resulting optical signals were measured. The light signal represents the presence of the inserted/flanking sequence, indicating that the amplification, hybridization, and single or multiple base extension reactions were successful.

The fluorescence polarization phenomenon described by Chen et al (Genome Res.)9:492-498, 1999) is also one method that can be used to detect the amplicons of the present invention. Using this method requires the design of an oligonucleotide strand that spans the intervening DNA sequence and adjacent genomic DNA binding sites. The oligonucleotide strand is hybridized to the single stranded PCR product of the target region (using one primer each in the intervening sequence and in the adjacent flanking genomic sequence) and then incubated with DNA polymerase and a fluorescently labeled ddNTPs. Single base extension will result in insertion of ddNTPs. This insertion can be measured for changes in its polarization using a fluorometer. The change in polarization represents the presence of the inserted/flanking sequence, indicating that the amplification, hybridization and single base extension reactions were successful.

Taqman is described as a method for detecting and quantifying the presence of DNA sequences, which is described in detail in the instructions provided by the manufacturer. Briefly, as illustrated below, a FRET oligonucleotide probe is designed to span the inserted DNA sequence and adjacent genomic flanking binding sites. The FRET probe and PCR primers (one primer for each of the insert and adjacent flanking genomic sequence) are cycled in the presence of a thermostable polymerase and dNTPs. Hybridization of the FRET probe results in cleavage of the fluorescent and quenching moieties on the FRET probe and release of the fluorescent moiety. The generation of a fluorescent signal represents the presence of the inserted/flanking sequence, indicating that amplification and hybridization were successful.

Suitable techniques for detecting plant material derived from transgenic maize event LP007-2 based on hybridization principles can also include Southern blot hybridization, Northern blot hybridization, and in situ hybridization. In particular, the suitable technique involves incubating the probe and sample, washing to remove unbound probe and detecting whether the probe has hybridised. The detection method depends on the type of label attached to the probe, for example, a radiolabeled probe can be detected by X-ray film exposure and development, or an enzymatically labeled probe can be detected by a color change achieved by substrate conversion.

Tyangi et al (Nat. Biotech.)14:303-308, 1996) describe the use of molecular markers for sequence detection. Briefly, a FRET oligonucleotide probe is designed to span the inserted DNA sequence and adjacent genomic flanking binding sites. The unique structure of the FRET probe results in it containing a secondary structure that is capable of retaining both a fluorescent moiety and a quenching moiety in close proximity. The FRET probe and PCR primers (one primer for each of the flanking genomic sequences within the insert and adjacent) are cycled in the presence of a thermostable polymerase and dNTPs. Upon successful PCR amplification, hybridization of the FRET probe to the target sequence results in loss of the secondary structure of the probe, thereby spatially separating the fluorescent moiety from the quencher moiety to produce a fluorescent signal. The generation of a fluorescent signal is representative of the presence of the inserted/flanking sequence, indicating that amplification and hybridization were successful.

Other described methods, such as microfluidics (microfluidics), provide methods and apparatus for isolating and amplifying DNA samples. The fluorochromes are used to detect and measure specific DNA molecules. A nano-tube (nanotube) device comprising an electronic sensor for detecting DNA molecules or nano-beads that bind to specific DNA molecules and can thus be detected is useful for detecting the DNA molecules of the present invention.

The DNA detection kit can be developed using the compositions described herein and methods described or known in the DNA detection art. The kit facilitates the identification of the presence of DNA of transgenic maize event LP007-2 in a sample and can also be used to cultivate maize plants containing DNA of transgenic maize event LP 007-2. The kit may contain DNA primers or probes homologous or complementary to at least a portion of

SEQ ID NO

1, 2, 3, 4 or 5, or other DNA primers or probes homologous or complementary to DNA contained in the transgenic genetic element of DNA, which DNA sequences may be used in DNA amplification reactions or as probes in DNA hybridization methods.

The DNA structure of the site of the maize genome containing the transgene insert and illustrated in figure 1 and table 1 comprises: a maize LP007-2 flanking genomic region located 5' to the transgenic insert, a portion of the insert from the right border Region (RB) of agrobacterium, a first expression cassette consisting of the figwort mosaic virus 35s promoter (prFMV), operably linked to the maize heat shock protein gene HSP70 protein intron (izmwsp 70), operably linked to the maize chloroplast transit peptide 2(spZmCTP2), operably linked to the insect resistant Cry2Ab protein (ccy 2Ab) of bacillus thuringiensis, operably linked to the nopaline synthase transcription terminator (tNos); the second expression cassette consists of tandem repeat maize ubiquitin gene promoter ubi (przmubi) containing enhancer region operably linked to insect resistance gene Vip3Aa (cVip3Aa) of bacillus thuringiensis operably linked to the 9 th intron of maize phosphoenolpyruvate carboxykinase gene operably linked to the 35s RNA sequence of cauliflower mosaic virus genome; the third expression cassette consists of cauliflower mosaic virus 35S promoter (pr35S), operably linked to the 5' untranslated leader sequence (lWtCab) of the wheat chloroplast a/b binding protein, operably linked to the rice actin gene 1 intron (iOsAct1), operably linked to the insect resistant Cry1Ab protein (ccy 1Ab) of bacillus thuringiensis, and operably linked to the terminator (tin2) of benzenesulfonamide inducible gene 2; the fourth expression cassette consists of the rice actin 1 promoter (prOsAct1), operably linked to the arabidopsis thaliana EPSPS chloroplast transit peptide (spAtCTP2), operably linked to the glyphosate tolerant 5-enol-pyruvylshikimate-3-phosphate synthase (cEPSPS) of the agrobacterium CP4 strain, and operably linked to the nopaline synthase transcription terminator (tNos). A portion of the insert from the left border region (LB) of Agrobacterium, and the genomic region flanking the LP007-2 maize plant located 3' of the transgenic insert (SEQ ID NO: 5). In the DNA amplification method, the DNA molecule used as a primer can be any portion derived from the transgene insert in transgenic maize event LP007-2, or any portion of the DNA region flanking the maize genome in transgenic maize event LP 007-2.

Transgenic corn event LP007-2 can be combined with other transgenic corn varieties, such as herbicide-tolerant corn (e.g., glufosinate, dicamba, etc.), or transgenic corn varieties carrying other insect-resistant genes (e.g., scarab, grub, diabrotica, etc.). All of these various combinations of different transgenic events, when bred with transgenic corn event LP007-2 of the present invention, can provide improved hybrid transgenic corn varieties that are resistant to a variety of insect pests and to a variety of herbicides. These varieties can exhibit more excellent characteristics such as an increase in yield as compared with non-transgenic varieties and single-trait transgenic varieties.

The present invention provides transgenic corn event LP007-2, nucleic acid sequences useful for detecting corn plants comprising the event and methods for detecting the same, transgenic corn event LP007-2 is resistant to feeding damage by lepidopteran pests and is resistant to the phytotoxic effects of glyphosate-containing agricultural herbicides. The corn plants with the dual traits express Cry1Ab, Cry2Ab and Vip3Aa proteins of Bacillus thuringiensis, which provide resistance to feeding damage by lepidopteran pests (such as Asian corn borer, Spodoptera frugiperda); and which expresses a glyphosate resistant 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) protein of agrobacterium strain CP4 which confers glyphosate tolerance to plants. The dual-character corn has the following advantages: 1) the corn borer is free from economic loss caused by lepidoptera pests (such as Asian corn borers, Spodoptera frugiperda, Oriental armyworms, Spodoptera frugiperda, cotton bollworms, cutworms, dichocrocis punctiferalis and the like), and the Asian corn borers, the Spodoptera frugiperda, the Oriental armyworms, the Spodoptera frugiperda, the cotton bollworms, the black cutworms, the dichocrocis punctiferalis and the like are main pests in a corn planting area; 2) the ability to apply glyphosate-containing agricultural herbicides to corn crops for broad-spectrum weed control; 3) the corn yield was not reduced. Specifically, the event LP007-2 of the invention has high resistance to insects, can enable the death rate of pests to reach 100%, and protects plants to enable the damage rate to be as low as 0%; the glyphosate herbicide tolerance is high, and the plant can be protected to reduce the damage rate to 0%; and the agronomic characters of the plants containing the event are excellent, and the yield percentage can reach 100 percent. Furthermore, the genes encoding the insect resistance and glyphosate tolerance traits are linked on the same DNA segment and are present at a single locus in the genome of transgenic maize event LP007-2, which provides enhanced breeding efficiency and enables the use of molecular markers to track the transgene insert in breeding populations and progeny thereof. Meanwhile, the primer or probe sequence provided by the detection method can generate an amplification product for diagnosing the transgenic corn event LP007-2 or the progeny thereof, and can quickly, accurately and stably identify the existence of the plant material derived from the transgenic corn event LP 007-2.

EXAMPLE 1 cloning and transformation

1.1 cloning of vectors

Recombinant expression vector pLP007 (shown in FIG. 2) was constructed using standard gene cloning techniques. The vector pLP007 comprises 4 transgenic expression cassettes in tandem, the first expression cassette consisting of the figwort mosaic virus 35s promoter (prFMV), operably linked to the intron of the heat shock protein gene HSP70 protein of maize (iZmHSP70), operably linked to the maize chloroplast transit peptide 2(spZmCTP2), operably linked to the insect resistant Cry2Ab protein of bacillus thuringiensis (ccy 2Ab), operably linked to the transcriptional terminator of nopaline synthase (tNos); the second expression cassette consists of tandem repeats of the maize ubiquitin gene promoter ubi (przmubi) containing an enhancer region operably linked to the insect resistance gene Vip3Aa (cVip3Aa) of bacillus thuringiensis operably linked to the 9 th intron of the maize phosphoenolpyruvate carboxykinase gene operably linked to the 35s RNA sequence of the cauliflower mosaic virus genome; the third expression cassette consists of a cauliflower mosaic virus 35S promoter (pr35S), operably linked to the 5' untranslated leader sequence (lWtCab) of the wheat chloroplast a/b binding protein, operably linked to the rice actin gene 1 intron (iOsAct1), operably linked to the insect resistant Cry1Ab protein (ccy 1Ab) of bacillus thuringiensis, and operably linked to the terminator (tin2) of benzenesulfonamide inducible gene 2; the fourth expression cassette consists of the rice actin 1 promoter (prOsAct1), operably linked to the arabidopsis thaliana EPSPS chloroplast transit peptide (spAtCTP2), operably linked to the glyphosate tolerant 5-enol-pyruvylshikimate-3-phosphate synthase (cEPSPS) of the agrobacterium CP4 strain, and operably linked to the nopaline synthase transcription terminator (tNos). The vector pLP007 was transformed into Agrobacterium LBA4404 (Invitrogen, Chicago, USA; Cat. No.: 18313-.

1.2 plant transformation

Transformation was performed by conventional Agrobacterium infection and the aseptically cultured maize embryos were co-cultured with Agrobacterium as described in example 1.1 to transfer the T-DNA of the constructed recombinant expression vector pLP007 into the maize genome to produce transgenic maize event LP 007-2.

For Agrobacterium-mediated transformation of maize, briefly, immature embryos are isolated from maize and the embryos are contacted with an Agrobacterium suspension, wherein the Agrobacterium is capable of delivering the nucleic acid sequence of the cry1Ab, cry2Ab, vip3Aa genes and the nucleic acid sequence of the epsps gene to at least one cell of one of the embryos (step 1: the infection step), in which the embryos are specifically immersed in an Agrobacterium suspension (OD660 ═ 0.4-0.6), an infection medium (MS salts 4.3g/L, MS vitamins, casein 300mg/L, sucrose 68.5g/L, glucose 36g/L, Acetosyringone (AS)40mg/L, 2, 4-dichlorophenoxyacetic acid (2,4-D)1mg/L, pH5.3) to initiate inoculation, the embryos are co-cultured with Agrobacterium for a period of time (3 days) (step 2: the co-culturing step). The young embryos are cultured on a solid medium (MS salt 4.3g/L, MS vitamin, casein 300mg/L, sucrose 20g/L, glucose 10g/L, Acetosyringone (AS)100mg/L, 2, 4-dichlorophenoxyacetic acid (2,4-D)1mg/L, agar 8g/L, pH5.8) after the infection step. After this co-cultivation phase, there may be an optional "recovery" step. In the "recovery" step, at least one antibiotic known to inhibit the growth of Agrobacterium (cefamycin) is present in the recovery medium (MS salts 4.3g/L, MS vitamins, casein 300mg/L, sucrose 30g/L, 2, 4-dichlorophenoxyacetic acid (2,4-D)1mg/L, plant gel 3g/L, pH5.8) without the addition of a selection agent for plant transformants (step 3: recovery step). In particular, young embryos are cultured on solid medium with antibiotics but no selective agent to eliminate Agrobacterium and provide a recovery period for the infected cells. Next, the inoculated immature embryos are cultured on a medium containing a selection agent (N- (phosphonomethyl) glycine) and the growing transformed calli are selected (step 4: selection step). Specifically, the immature embryos are cultured on a selective solid medium (MS salt 4.3g/L, MS vitamin, casein 300mg/L, sucrose 30g/L, N- (phosphonomethyl) glycine 0.25mol/L, 2, 4-dichlorophenoxyacetic acid (2,4-D)1mg/L, plant gel 3g/L, pH5.8) with a selective agent, resulting in selective growth of transformed cells. Then, the callus is regenerated into a plant (step 5: regeneration step), and specifically, the callus grown on the medium containing the selection agent is cultured on a solid medium (MS differentiation medium and MS rooting medium) to regenerate the plant.

The resistant callus obtained by screening was transferred to the MS differentiation medium (MS salt 4.3g/L, MS vitamin, casein 300mg/L, sucrose 30g/L, 6-benzyladenine 2mg/L, N- (phosphonomethyl) glycine 0.125mol/L, plant gel 3g/L, pH5.8), and cultured and differentiated at 25 ℃. The differentiated plantlets were transferred to the MS rooting medium (MS salts 2.15g/L, MS vitamins, casein 300mg/L, sucrose 30g/L, indole-3-acetic acid 1mg/L, agar 8g/L, pH5.8), cultured at 25 ℃ until the height was about 10cm, and transferred to a greenhouse for fructification. In the greenhouse, the culture was carried out at 28 ℃ for 16 hours and at 20 ℃ for 8 hours each day.

3.2 analysis of flanking DNA sequences

And (3) carrying out concentration measurement on the extracted DNA sample so that the concentration of the sample to be measured is between 80 and 100 ng/. mu.L. The genomic DNA was digested with the selected restriction enzymes SpeI, PstI, BssHII (5 '-end analysis) and SacI, KpnI, XmaI, NheI (3' -end analysis), respectively. To each digestion system were added 26.5. mu.L of genomic DNA, 0.5. mu.L of the above selected restriction enzyme and 3. mu.L of digestion buffer, and the mixture was digested at an appropriate temperature for 1 hour. After the enzyme digestion is finished, 70 mu L of absolute ethyl alcohol is added into the enzyme digestion system, ice bath is carried out for 30min, the centrifugal treatment is carried out for 7min at the rotating speed of 12000rpm, the supernatant is discarded and dried, and then 8.5 mu L of double distilled water (ddH) is added₂O), 1. mu.L of 10X T4 Buffer and 0.5. mu. L T4 ligase at temperature 4The ligation was performed overnight at DEG C. PCR amplification with a series of nested primers isolates 5 'and 3' transgene/genomic DNA. Specifically, the primer combination for separating 5' transgene/genome DNA comprises SEQ ID NO 13 and SEQ ID NO 34 as first primers, SEQ ID NO 35 and SEQ ID NO 36 as second primers, and SEQ ID NO 13 as sequencing primers. The primer combination for separating the 3' transgene/genome DNA comprises SEQ ID NO 15 and SEQ ID NO 37 as first primers, SEQ ID NO 38 and SEQ ID NO 39 as second primers, SEQ ID NO 15 as a sequencing primer, and the PCR reaction conditions are shown in Table 3.

The obtained amplicons were electrophoresed on a 2.0% agarose Gel to separate the PCR reactions, followed by separation of the fragment of interest from the agarose matrix using QIAquick Gel extraction kit (catalog # 28704, Qiagen inc, Valencia, CA). The purified PCR products are then sequenced (e.g., ABI prism 377, PE Biosystems, Foster City, CA) and analyzed (e.g., DNASTAR sequence analysis software, DNASTAR inc., Madison, WI).

The 5 'and 3' flanking sequences and junction sequences were confirmed using standard PCR methods. The 5' flanking and junction sequences may be confirmed using SEQ ID NO 8 or 12 in combination with SEQ ID NO 9, 13 or 34. The 3' flanking and junction sequences may be confirmed using SEQ ID NO 11 or 14 in combination with SEQ ID NO 10, 15 or 37. The PCR reaction system and amplification conditions are shown in tables 2 and 3. One skilled in the art will appreciate that other primer sequences may also be used to confirm the flanking and junction sequences.

DNA sequencing of the PCR products provides DNA that can be used to design other DNA molecules that serve as primers and probes for the identification of maize plants or seeds derived from transgenic maize event LP 007-2.

It was found that the maize genomic sequence shown at nucleotides 1-456 of SEQ ID NO:5 flanked the right border of the transgenic maize event LP007-2 insert sequence (the 5 'flanking sequence), and that the maize genomic sequence shown at nucleotides 16623-17205 of SEQ ID NO:5 flanked the left border of the transgenic maize event LP007-2 insert sequence (the 3' flanking sequence). The 5 'junction sequence is set forth in SEQ ID NO 1 and the 3' junction sequence is set forth in SEQ ID NO 2.

3.3 PCR conjugation assay

The adaptor sequence is a relatively short polynucleotide molecule that is a novel DNA sequence that is diagnostic for the DNA of transgenic maize event LP007-2 when detected in a polynucleic acid detection assay. The binding sequence of SEQ ID NO. 1 consists of 11bp each on one side of the T-DNARB region insertion site of transgenic maize event LP007-2 and the maize genomic DNA insertion site, and the binding sequence of SEQ ID NO. 2 consists of 11bp each on the other side of the T-DNARB region insertion site of transgenic maize event LP007-2 and the maize genomic DNA insertion site. Longer or shorter polynucleotide joining sequences may be selected from SEQ ID NO. 3 or SEQ ID NO. 4. The junction sequences (5 'junction region SEQ ID NO:1, and 3' junction region SEQ ID NO:2) are useful in DNA detection methods as DNA probes or as DNA primer molecules. The junction sequences SEQ ID NO 6 and SEQ ID NO 7 are also novel DNA sequences in transgenic maize event LP007-2 that can also be used as DNA probes or as DNA primer molecules to detect the presence of transgenic maize event LP007-2 DNA. The SEQ ID NO:6 (nucleotide 457-820 of SEQ ID NO: 3) spans the LP007 construct DNA sequence and the tNOs transcription termination sequence, and the SEQ ID NO:7 (nucleotide 1-252 of SEQ ID NO: 4) spans the tNOs transcription termination sequence and the LP007 construct DNA sequence.

In addition, an amplicon is generated by using primers from at least one of SEQ ID NO 3 or SEQ ID NO 4 that when used in a PCR method produce a diagnostic amplicon of transgenic maize event LP 007-2.

Specifically, a PCR product is generated from the 5 'end of the transgene insert, which PCR product is a portion of the genomic DNA comprising the 5' end of the T-DNA insert flanking the genome of the plant material derived from transgenic maize event LP 007-2. This PCR product contained SEQ ID NO 3. For PCR amplification, primer 5(SEQ ID NO:8) hybridizing to the genomic DNA sequence flanking the 5' end of the transgene insert sequence, and primer 6(SEQ ID NO:9) at the transgene tNOs transcription termination sequence, are designed to pair with it.

A PCR product comprising a portion of genomic DNA flanking the 3 'end of the T-DNA insert in the genome of plant material derived from the transgenic maize event LP007-2 was generated from the 3' end of the transgenic insert. This PCR product contained SEQ ID NO 4. For PCR amplification, primer 8(SEQ ID NO:11) hybridizing to the genomic DNA sequence flanking the 3 'end of the transgene insert was designed, along with primer 7(SEQ ID NO:10) pairing to the tNos transcription termination sequence located at the 3' end of the insert.

The DNA amplification conditions set forth in tables 3 and 4 can be used in the PCR zygosity assay described above to produce a diagnostic amplicon of transgenic maize event LP 007-2. Detection of amplicons can be performed by using a Stratagene Robocycle, MJ Engine, Perkin-Elmer9700, or Eppendorf MastercycleGradien thermocycler, etc., as shown in Table 3, or by methods and equipment known to those skilled in the art.

TABLE 4 Perkin-Elmer9700 thermal cycler conditions

Mix gently, and if there is no incubation cap on the thermocycler, 1-2 drops of mineral oil can be added above each reaction. PCR was performed on a Stratagene Robocycler (Stratagene, La Jolla, CA), MJ Engine (MJ R-Biorad, Hercules, CA), Perkin-Elmer9700 (Perkin Elmer, Boston, MA) or Eppendorf Mastercycler Gradient (Eppendorf, Hamburg, Germany) thermocycler using the following cycling parameters (Table 3). The MJ Engine or Eppendorf Mastercycler Gradient thermocycler should operate in a computational mode. The Perkin-Elmer9700 thermal cycler was operated with a ramp speed set to a maximum value.

The experimental results show that: primers 11 and 12(SEQ ID NOS: 8 and 9) which, when used in a PCR reaction of transgenic maize event LP007-2 genomic DNA, produced an amplification product of a 1646bp fragment, with NO fragment being amplified when used in a PCR reaction of untransformed maize genomic DNA and non-LP 007-2 maize genomic DNA; primers 13 and 14(SEQ ID NOS: 10 and 11) produced an amplification product of a 1333bp fragment when used in a PCR reaction of transgenic maize event LP007-2 genomic DNA, and NO fragment was amplified when used in a PCR reaction of untransformed maize genomic DNA and non-LP 007-2 maize genomic DNA.

PCR zygosity assays can also be used to identify whether the material derived from transgenic maize event LP007-2 is homozygous or heterozygous. Primer 15(SEQ ID NO:12), primer 16(SEQ ID NO:13) and primer 17(SEQ ID NO:14), or primer 16(SEQ ID NO:13), primer 17(SEQ ID NO:14) and primer 18(SEQ ID NO:15) were used in an amplification reaction to generate a diagnostic amplicon of transgenic maize event LP 007-2. The DNA amplification conditions set forth in tables 5 and 6 can be used in the zygosity assay described above to produce a diagnostic amplicon for transgenic maize event LP 007-2.

TABLE 6 determination of bondability Perkin-Elmer9700 thermal cycler conditions

PCR was performed on a Stratagene Robocycler (Stratagene, La Jolla, CA), MJ Engine (MJ R-Biorad, Hercules, CA), Perkin-Elmer9700 (Perkin Elmer, Boston, MA) or Eppendorf MastercycleGradient (Eppendorf, Hamburg, Germany) thermocycler using the following cycling parameters (Table 5). The MJ Engine or Eppendorf Mastercycler Gradient thermocycler should operate in a computational mode. The Perkin-Elmer9700 thermal cycler was operated with a ramp speed set to a maximum value.

In the amplification reaction, the biological sample containing the template DNA contains DNA diagnostic for the presence of transgenic maize event LP007-2 in the sample. Or the reaction will produce two different DNA amplicons from a biological sample containing DNA derived from the maize genome that is heterozygous for the corresponding allele of the inserted DNA present in transgenic maize event LP 007-2. These two different amplicons will correspond to a first amplicon derived from the wild-type maize genomic locus and a second amplicon diagnostic for the presence of the transgenic maize event LP007-2 DNA. Only a maize DNA sample corresponding to a single amplicon of the second amplicon described for the heterozygous genome is produced, the presence of transgenic maize event LP007-2 in the sample can be diagnostically determined, and the sample is produced from maize seeds that are homozygous for the allele corresponding to the inserted DNA present in the transgenic maize plant LP 007-2. It is noted that the primer pair for transgenic maize event LP007-2 was used to generate an amplicon diagnostic for transgenic maize event LP007-2 genomic DNA. These primer pairs include, but are not limited to, primers 11 and 12(SEQ ID NOS: 8 and 9), and primers 13 and 14(SEQ ID NOS: 10 and 11), which are used in the DNA amplification method. In addition, a control primer 9 and 10(SEQ ID NO:28 and SEQ ID NO:29) for amplification of the maize endogenous gene was included as an internal standard of reaction conditions. Analysis of a sample of a DNA extract of transgenic maize event LP007-2 should include a control of positive tissue DNA extract of transgenic maize event LP007-2, a control of negative DNA extract from non-transgenic maize event LP007-2, and a negative control that does not contain a template maize DNA extract. In addition to these primer pairs, any primer pair from SEQ ID NO 3 or SEQ ID NO 4, or the complement thereof, which when used in a DNA amplification reaction produces an amplicon comprising SEQ ID NO 1 or SEQ ID NO 2, respectively, that is diagnostic for tissue derived from transgenic event maize plant LP007-2 can be used. The DNA amplification conditions illustrated in tables 2-5 can be used to generate diagnostic amplicons of transgenic maize event LP007-2 using appropriate primer pairs. An extract of a maize plant or seed DNA putatively containing a transgenic maize event LP007-2, or a product derived from transgenic maize event LP007-2, that when tested in a DNA amplification method produces an amplicon diagnostic for transgenic maize event LP007-2, can be used as a template for amplification to determine the presence or absence of transgenic maize event LP 007-2.

Example 4 detection of transgenic maize event LP007-2 by Southern blot hybridization

4.1 DNA extraction for Southern blot hybridization

Southern blot analysis was performed using transformation events homozygous for the T4, T5 generations. Approximately 5 to 10g of plant tissue was ground in liquid nitrogen using a mortar and pestle. Plant tissues were resuspended in 12.5mL extraction buffer a (0.2MTris pH 8.0, 50mM EDTA, 0.25M NaCl, 0.1% v/v β -mercaptoethanol, 2.5% w/v polyvinyl-pyrrolidone) and centrifuged at 4000rpm for 10 minutes (2755 g). After discarding the supernatant, the pellet was resuspended in 2.5mL extraction buffer B (0.2M Tris pH 8.0, 50mM EDTA, 0.5M NaCl, 1% v/v β -mercaptoethanol, 2.5% w/v polyvinyl-pyrrolidone, 3% sarcosyl, 20% ethanol) and incubated at 37 ℃ for 30 minutes. During the incubation period, the sample was mixed once with a sterile loop. After incubation, an equal volume of chloroform/isoamyl alcohol (24:1) was added, gently mixed by inversion, and centrifuged at 4000rpm for 20 minutes. The aqueous layer was collected and centrifuged at 4000rpm for 5 minutes after adding 0.54 volume of isopropanol to precipitate the DNA. The supernatant was discarded and the DNA pellet resuspended in 500. mu.L TE. To degrade any RNA present, DNA was incubated with 1. mu.L of 30mg/mL RNAaseA for 30 minutes at 37 ℃, centrifuged at 4000rpm for 5 minutes, and the DNA was precipitated by centrifugation at 14000rpm for 10 minutes in the presence of 0.5 volumes of 7.5M ammonium acetate and 0.54 volumes of isopropanol. After discarding the supernatant, the pellet was washed with 500. mu.L of 70% by mass ethanol, dried and resuspended in 100. mu.L of TE.

4.2 restriction enzyme digestion

The DNA concentration is quantified using a spectrophotometer or fluorometer (using 1 XTAE and GelRED dyes). Mu.g of DNA was digested in 100. mu.L reaction. Genomic DNA was digested with the restriction enzymes BamHI and HindIII, respectively, and with the partial sequence of EPSPS on T-DNA as a probe, with the restriction enzymes EcoRV and SpeI, respectively, and with the partial sequence of Cry2Ab on T-DNA as a probe, with the restriction enzymes EcoRV and HindIII, respectively, with the partial sequences of Cry1Ab and Vip3Aa on T-DNA as a probe. For each enzyme, the digests were incubated overnight at the appropriate temperature. The sample was spun using a vacuum centrifugal evaporator concentrator (speed vacuum) to reduce the volume to 30 μ L.

4.3 gel electrophoresis

Bromophenol blue loading dye was added to each sample from example 4.2, and each sample was loaded onto a 0.7% agarose gel containing ethidium bromide, electrophoresed in TBE electrophoresis buffer, and the gel was electrophoresed overnight at 20 volts.

The gel was washed in 0.25M HCl for 15 minutes to depurinate the DNA, then washed with water. Southern blot hybridization was set as follows: in the tray, 20 sheets of thick dry blotting paper were placed, and 4 sheets of thin dry blotting paper were placed thereon. 1 piece of thin blotting paper was pre-wetted in 0.4M NaOH and placed on the stack, followed by 1 piece of Hybond-N + transfer membrane pre-wetted in 0.4M NaOH (Amersham Pharmacia Biotech, # RPN 303B). The gel is placed on top to ensure that there are no air bubbles between the gel and the membrane. 3 additional pre-soaked blotting papers were placed on top of the gel and the buffer tray was filled with 0.4M NaOH. The gel stack and buffer tray were connected with wicks pre-soaked in 0.4M NaOH to transfer the DNA to the membrane. The DNA transfer was carried out at room temperature for about 4 hours. After transfer, the Hybond membrane was rinsed in2 XSSC for 10 seconds and the DNA was bound to the membrane by UV cross-linking.

4.4 hybridization

PCR was used to amplify appropriate DNA sequences for probe preparation. The DNA probe is SEQ ID NO. 30, SEQ ID NO. 31, SEQ ID NO. 32 and SEQ ID NO. 33, or is homologous or complementary with the above sequences. 25ng of the probe DNA was boiled in 45. mu.L of TE for 5 minutes, placed on ice for 7 minutes, and then transferred to a Rediprime II (Amersham Pharmacia Biotech, # RPN1633) tube. After adding 5. mu.l of 32P-labeled dCTP to the Rediprime tube, the probe was incubated at 37 ℃ for 15 minutes. The probe was purified by microcentrifugation of a G-50 column (Amersham Pharmacia Biotech, #27-5330-01) according to the manufacturer's instructions to remove unincorporated dNTPs. Probe activity was measured using a scintillation counter. By preheathing Church prehybridization with 20mL (500mM Na) at 65 deg.C₃P0₄1mM EDTA, 7% SDS, 1% BSA) wet the Hybond membrane for 30 minutes, pre-hybridizing the Hybond membrane. The labeled probe was boiled for 5 minutes and placed on ice for 10 minutes. Add appropriate amount of probe to the prehybridization buffer (1 million counts per 1mL prehybridization buffer) and perform hybridization overnight at 65 ℃. The following day, the hybridization buffer was discarded, and after rinsing with 20mL of Church rinse solution 1(40mM Na3P04, 1mM EDTA, 5% SDS, 0.5% BSA), the membrane was washed in 150mL of Church rinse solution 1 at 65 ℃ for 20 minutes. Rinse solution 2 with Church (40mM Na)₃P0₄1mM EDTA, 1% SDS) was repeated 2 times. The membrane is exposed to a phosphor screen or X-ray film to detect the location of probe binding.

Two control samples were included on each Southern: (1) DNA from a negative (untransformed) isolate, which is used to identify any endogenous maize sequence that can hybridize to the element-specific probe; (2) DNA from a positive isolate, into which HindIII digested pLP007 was introduced in an amount equivalent to one copy number based on probe length, to demonstrate the sensitivity of the experiment in detecting a single gene copy within the maize genome.

The hybridization data provide corroborative evidence supporting TaqMan^TMPCR analysis, i.e., maize plant LP007-2 contained a single copy of Cry1Ab, Cry2Ab, Vip3Aa, and the EPSPS genes. Enzymatic digestion with Cry1Ab probe, EcoRV and HindIII yielded a size of about 17.7k, respectivelyb and a single band of 14.6 kb; by using the Cry2Ab probe, EcoRV and SpeI are subjected to enzymolysis to generate single bands with the sizes of about 17.7kb and 11.5kb respectively; using the Vip3Aa probe, EcoRV and HindIII were digested to generate single bands of about 17.7kb and 14.6kb in size, respectively; using this EPSPS probe, BamHI and HindIII were digested to generate single bands of approximately 5.1kb and 12.5kb in size, respectively. This indicates that one copy each of Cry1Ab, Cry2Ab, Vip3Aa, and EPSPS is present in maize transformation event LP 007-2.

Example 5 insect resistance assay

5.1 bioassay of maize plant LP007-2

(1) Corn borer

The insect-resistant herbicide-tolerant corn LP007-2 is used for carrying out field inoculation verification on the resistance of a main target pest namely Asian corn borer. Inoculating insects at the 4-6 leaf stage and the silking stage (silking of female ear is 3-5cm), each for 2 times, 50 times each time, and the interval time of the two times is one week. After 14d of inoculation of the corn borers in the leaf stage, the feeding condition of the upper leaves of the corn plants by the Asiatic corn borers is investigated plant by plant, and the leaf feeding level of the Asiatic corn borers is recorded. After the silking period is inoculated with the insects, the damage degree of the female ears and the damage condition of plants before harvesting comprise the damage length of the female ears of the corn, the number of wormholes, the length of tunnels of the wormholes, the age of the living larvae and the number of the living larvae. Evaluation was performed using "heart-leaf-as-harmful-level grading criteria" as an index, and the results are shown in fig. 4 and table 12. The ears are dissected and investigated in the silking period, and the statistical result is shown in a table 13.
