Abstract

A novel transgenic corn event designated MIR162 is disclosed. The invention relates to nucleic acids from event MIR162. The invention also relates to assays for detecting the presence of the MIR162 event based on DNA sequences of the recombinant constructs inserted into the corn genome that resulted in the MIR162 event and of genomic sequences flanking the insertion sites. The invention further relates to corn plants comprising the genotype of MIR162 and to methods for producing a corn plant by crossing a corn plant comprising the MIR162 genotype with itself or another corn variety. Seeds of corn plants comprising the MIR162 genotype are also objects of the present invention. The invention also relates to methods of controlling insects using MIR162 corn plants.

Claims

59, and the complements thereof.

2. A MIR162 corn seed comprising a nucleic acid molecule selected from the group consisting of SEQ ID NO:

1, SEQ ID NO;

38, SEQ ID NO;

41, SEQ ID NO;

45, SEQ ID NO;

47, SEQ ID NO;

49, SEQ ID NO;

55, SEQ ID NO;

59, and the complements thereof, an example of the seed being deposited at the American Type Culture Collection under the accession number PTA-8166.

3. A biological sample derived from a event MIR162 corn plant, tissue, or seed, wherein the sample comprises a nucleotide sequence which is or is complementary to SEQ ID NO:

1, SEQ ID NO;

38, SEQ ID NO;

41, SEQ ID NO;

45, SEQ ID NO;

47, SEQ ID NO;

49, SEQ ID NO;

59 and wherein the sequence is detectable in the sample using a nucleic acid amplification or nucleic acid hybridization method.

4. The biological sample of claim 3 wherein the sample is selected from the group consisting of corn flour, corn meal, corn syrup, corn oil, corn starch, and cereals manufactured in whole or in part to contain corn by-products.

5. An extract derived from the biological sample according to claim 3, wherein the extract comprises a nucleotide sequence which is or is complementary to SEQ ID NO:

1, SEQ ID NO;

7. A method for producing a corn plant resistant to lepidopteran pests comprising:

(a) sexually crossing a first parent corn plant with a second parent corn plant, wherein said first or second parent corn plant comprises event MIR162 DNA, thereby producing a plurality of first generation progeny plants;

(b) selecting a first generation progeny plant that is resistant to lepidopteran insect infestation;

(c) selfing the first generation progeny plant, thereby producing a plurality of second generation progeny plants;

47, SEQ ID NO;

49, SEQ ID NO;

55, or SEQ ID NO;

59.

8. A method of producing hybrid corn seeds comprising:

(a) planting seeds of a first inbred corn line comprising event MIR162 DNA and seeds of a second inbred line having a genotype different from the the first inbred corn line;

(b) cultivating corn plants resulting from said planting until time of flowering;

(c) emasculating said flowers of plants of one of the corn inbred lines;

(d) sexually crossing the two different inbred lines with each other; and

(e) harvesting the hybrid seed produced thereby;

wherein the hybrid corn seeds comprise SEQ ID NO;

1, SEQ ID NO;

38, SEQ ID NO;

41, SEQ ID NO;

45, SEQ ID NO;

10. Hybrid seed produced by the method of claim 8.

11. A transgenic non-human host cell comprising event MIR162 DNA comprising a nucleic acid molecule selected from the group consisting of SEQ ID NO:

1, SEQ ID NO;

38, SEQ ID NO;

41, SEQ ID NO;

45, SEQ ID NO;

47, SEQ ID NO;

49, SEQ ID NO;
