INIR12 transgenic maize
Transgenic INIR12 maize plants comprising a vip3Aa19 expression cassette linked to a secondary nopaline synthase terminator element which lack a selectable marker gene and/or which comprise modifications that provide for facile excision of the INIR12 transgenic locus from the maize plant genome are provided. Genomic DNA of INIR12 transgenic plants, detection of INIR12 plants and products thereof, methods of making INIR12 plants, and use of INIR12 plants to facilitate breeding are disclosed.
1. A transgenic maize plant cell comprising a transgenic locus comprising the sequence of SEQ ID NO: 44 or a transgenic locus comprising the integrated cognate guide RNA recognition site (CgRRS) of SEQ ID NO: 37 in the 5′ junction polynucleotide of the MIR162 transgenic locus present in seed deposited at the ATCC under accession No. PTA-8166, wherein the CgRRS of SEQ ID NO: 37 is integrated in the same location and orientation in the 5′ junction polynucleotides of SEQ ID NO: 44 and the MIR162 transgenic locus.
2. A transgenic maize plant seed comprising a transgenic locus comprising the sequence of SEQ ID NO: 44 or a transgenic locus comprising the integrated cognate guide RNA recognition site (CgRRS) of SEQ ID NO: 37 in the 5′ junction polynucleotide of the MIR162 transgenic locus present in seed deposited at the ATCC under accession No. PTA-8166, wherein the CgRRS of SEQ ID NO: 37 is integrated in the same location and orientation in the 5′ junction polynucleotides of SEQ ID NO: 44 and the MIR162 transgenic locus.
3. A transgenic maize plant comprising a transgenic locus comprising the sequence of SEQ ID NO: 44 or a transgenic locus comprising the integrated cognate guide RNA recognition site (CgRRS) of SEQ ID NO: 37 in the 5′ junction polynucleotide of the MIR162 transgenic locus present in seed deposited at the ATCC under accession No. PTA-8166, wherein the CgRRS of SEQ ID NO: 37 is integrated in the same location and orientation in the 5′ junction polynucleotides of SEQ ID NO: 44 and the MIR162 transgenic locus.
4. A method for obtaining a bulked population of seed comprising selfing the transgenic maize plant of claim 3 and harvesting transgenic seed comprising the transgenic locus comprising the sequence of SEQ ID NO: 44 or the transgenic locus comprising the integrated cognate guide RNA recognition site (CgRRS) of SEQ ID NO: 37 in the 5′ junction polynucleotide of the MIR162 transgenic locus present in seed deposited at the ATCC under accession No. PTA-8166, wherein the CgRRS of SEQ ID NO: 37 is integrated in the same location and orientation in the 5′ junction polynucleotides of SEQ ID NO: 44 and the MIR162 transgenic locus.
