Abstract

The invention provides a transgenic corn event MON95275, plants, plant cells, seeds, plant parts (including pollen, seed, and cells, and tissues corresponding to tassel, root, stalk, stem, leaf, cobb, and the like), progeny plants, commodity products comprising detectable amounts of corn event MON95275 DNA. The invention also provides polynucleotides specific for corn event MON95275 and methods for using and detecting corn event MON95275 DNA as well as plants, plant cells, seeds, plant parts, progeny plants, and commodity products comprising corn event MON95275. The invention also provides methods related to making and using corn event MON95275.

First claim

1 - 5 . (canceled)

6 . A method of detecting the presence of a DNA segment diagnostic for corn event MON95275 DNA in a sample, said method comprising:
a) contacting said sample with the DNA molecule of claim 3 ; b) subjecting said sample and said DNA molecule to stringent hybridization conditions; and c) detecting hybridization of said DNA molecule to said DNA in said sample, wherein said detection is diagnostic for the presence of said corn event MON95275 DNA in said sample.

7 - 11 . (canceled)

12 . A method for protecting a corn plant from insect infestation, wherein said method comprises providing in the diet of a Coleopteran insect pest an insecticidally effective amount of cells or tissue of the corn plant comprising corn event MON95275.

13 . The method of claim 12 , wherein said Coleopteran insect pest is selected from the group consisting of Western Corn Rootworm ( Diabrotica virgifera virgifera ) and Northern Corn Rootworm ( Diabrotica barberi ).

14 . A method of producing a corn rootworm resistant corn plant comprising:
a) breeding two different corn plants with at least one of the two different corn plants comprising corn event MON95275 DNA to produce progeny; b) confirming in said progeny the presence of a DNA segment diagnostic for corn event MON95275 DNA; and c) selecting said progeny comprising corn event MON95275 DNA; wherein said progeny of step c) are corn rootworm resistant.

15 - 21 . (canceled)

22 . A method of determining the zygosity of a corn plant or corn seed comprising corn event MON95275 comprising:
a) contacting a sample comprising corn DNA with a first primer pair that is capable of producing an amplicon diagnostic for the allele corresponding to corn event MON95275 DNA; b) contacting said sample with a second primer pair that is capable of producing, using a thermal amplification reaction, an amplicon of an internal standard corn genomic DNA known to be single-copy and homozygous in the corn plant; c) contacting said sample with a probe set which contains at least a first probe that specifically hybridizes to (or with) the allele DNA of corn event MON95275, and a second probe that specifically hybridizes to the internal standard corn genomic DNA known to be single-copy and homozygous in the corn plant; d) performing a DNA amplification reaction using real-time PCR and determining the cycle thresholds (Ct values) of the amplicon corresponding to the allele DNA of corn event MON95275 and the single-copy, homozygous internal standard; e) calculating the difference (□Ct) between the Ct value of the single-copy, homozygous internal standard amplicon and the Ct value of the amplicon corresponding to the allele DNA of corn event MON95275; and f) determining zygosity, wherein a □Ct of about zero (0) indicates homozygosity of the inserted T-DNA of event MON95275 and a □Ct of about one (1) indicates heterozygosity of the inserted T-DNA of corn event MON95275.

23 . The method of claim 22 , wherein the primer pairs are selected from the group consisting of SEQ ID NO:15 combined with SEQ ID NO:16, and SEQ ID NO:18 combined with SEQ ID NO:19; and wherein the probes are SEQ ID NO:17 and SEQ ID NO:20.

24 . The method of claim 22 , wherein the □Ct of about one (1) indicating heterozygosity of the inserted T-DNA of MON95275 is in the range of 0.75 to 1.25.

25 . A method of determining the zygosity of a corn plant or corn seed comprising corn event MON95275 comprising:
a) contacting a sample comprising corn DNA with a set of primer pairs comprising at least two different primer pairs capable of producing a first amplicon diagnostic for corn event MON95275 and a second amplicon diagnostic for native corn genomic DNA devoid of corn event MON95275 DNA; b) performing a nucleic acid amplification reaction with the sample and the set of primer pairs; and c) detecting in the nucleic acid amplification reaction the first amplicon diagnostic for the presence of corn event MON95275 DNA, or the second amplicon diagnostic for native corn genomic DNA devoid of corn event MON95275, wherein the presence of only the first amplicon is diagnostic of a corn plant or corn seed homozygous for corn event MON95275 DNA, and the presence of both the first amplicon and the second amplicon is diagnostic of a corn plant or corn seed heterozygous for corn event MON95275 DNA; or d) contacting a sample comprising corn DNA with a probe set which contains at least a first probe that specifically hybridizes to corn event MON95275 DNA and at least a second probe that specifically hybridizes to corn genomic DNA that was disrupted by insertion of the heterologous DNA of corn event MON95275 and does not hybridize to corn event MON95275 DNA; and e) hybridizing the probe set with the sample under stringent hybridization conditions, wherein detecting hybridization of only the first probe under the hybridization conditions is diagnostic for a homozygous allele of corn event MON95275 DNA, and wherein detecting hybridization of both the first probe and the second probe under the hybridization conditions is diagnostic for a corn plant or seed heterozygous for corn event MON95275 DNA.

26 . The method of claim 25 , wherein the set of primer pairs comprises SEQ ID NO:15 combined with SEQ ID NO:16, and SEQ ID NO:21 combined with SEQ ID NO:22.

27 . The method of claim 26 , wherein the probe set comprises SEQ ID NO:17 and SEQ ID NO:23.
