Abstract
The present invention provides assays for detecting the presence of the PV-BNGT04(RT73) canola event based on the DNA sequence of the recombinant construct inserted into the canola genome and of genomic sequences flanking the insertion site.
Claims7
A DNA molecule comprising a DNA sequence selected from the group consisting of SEQ ID NO:
- 7 and SEQ ID NO:
- 8.
A method of detecting the presence of DNA corresponding to the genomic/transgene DNA of canola PV-BNGT04(RT73) event and progeny thereof in a sample, the method comprising:
- (a) contacting the sample comprising canola DNA with a primer pair that when used in a nucleic acid amplification reaction with DNA from canola PV-BNGT04(RT73), produces an amplicon that is diagnostic for canola PV-BNGT04(RT73);
- and
- (b) performing the nucleic acid amplification reaction, thereby producing the amplicon;
- and
- (c) detecting the amplicon.
A DNA detection kit specific for genomic/transgene DNA of canola PV-BNGT04(RT73) and progeny thereof comprising:
- (a) a pair of DNA molecules, wherein a first molecule in said pair comprises 11 nucleotides or more of SEQ ID NO:
- 7, or a sequence fully complementary thereto, wherein said pair is capable of producing an amplicon diagnostic for event PV-BNGT04(RT73), wherein said amplicon comprises SEQ ID NO:
- 5;
- or
- (b) a pair of DNA molecules, wherein a first molecule in said pair comprises 11 nucleotides or more of SEQ ID NO:
- 8, or a sequence fully complementary thereto, wherein said pair is capable of producing an amplicon diagnostic for event PV-BNGT04(RT73), wherein said amplicon comprises SEQ ID NO:
- 6.
A method of detecting the presence of a genomic/transgene DNA corresponding to the PV-BNGT04(RT73) and progeny thereof in a sample, the method comprising:
- (a) contacting the sample comprising canola DNA with a polynucleotide probe that hybridizes under stringent hybridization conditions with DNA from canola event PV-BNGT04(RT73) and progeny thereof and does not hybridize under the stringent hybridization conditions with a non-PV-BNGT04(RT73) and progeny thereof canola plant DNA;
- and
- (b) subjecting the sample and probe to stringent hybridization conditions;
- (c) detecting hybridization of the probe to the DNA.
An isolated DNA molecule comprising a genomic/transgene DNA junction sequence of canola PV-BNGT04 or a sequence fully complementary thereto.
A method of breeding a glyphosate tolerant trait into canola plants comprising:
- (a) extracting a DNA sample from progeny canola plants;
- (b) detecting in the DNA sample a nucleic acid molecule selected from the group consisting of SEQ ID NO:
- 5, SEQ ID NO:
- 6, and a sequence fully complementary thereto;
- and
- (c) performing a marker assisted breeding method for the glyphosate tolerant trait, wherein the glyphosate tolerant trait is genetically linked to a complement of the marker nucleic acid molecule.
