Abstract

Insecticidal toxins derived from Bacillus thuringiensis, polynucleotides encoding such toxins, use of such toxins to control Coleopteran plant pests, and transgenic plants that produce, and are protected, by these toxins are described.

First claim

What is claimed is:

1. A nucleic acid construct comprising, a nucleic acid sequence encoding an insecticidal IRDIG protein comprising a sequence having at least 99% sequence identity with any one of SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 71, 73, 75, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110, 112, 114, 116, 118, 120, and 122, and a heterologous regulatory element.

2. A nucleic acid construct comprising a nucleic acid sequence of claim 1 encoding an insecticidal IRDIG protein comprising any one of SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 71, 73, 75, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110, 112, 114, 116, 118, 120, and 122.

3. A plant or plant part comprising the construct of claim 1 .

4. The plant part of claim 3 wherein the plant part is a seed.

5. A plant or plant part comprising the construct of claim 2 .

6. The plant part of claim 5 wherein the plant part is a seed.

7. A plant or plant part comprising an insecticidal IRDIG protein encoded by the construct of claim 1 .

8. The plant part of claim 7 wherein the plant part is a seed.

9. A plant or plant part comprising an insecticidal IRDIG protein encoded by the construct of claim 2 .

10. The plant or plant part of claim 7 , wherein the insecticidal IRDIG protein has insecticidal activity against an insect selected from the group consisting of the order Coleoptera and Western Corn Rootworm.

11. The seed of claim 8 wherein the insecticidal IRDIG protein has insecticidal activity against an Coleoptera or Western Corn Rootworm insects.

12. A method for producing a coleopteran-tolerant plant comprising breeding a non-transgenic plant with a transgenic plant comprising the construct of claim 1 , stably incorporated into the genome of the plant, and selecting one or more progeny plants by analyzing for at least a portion of the construct in the one or more selected progeny plants.

13. A method for producing a coleopteran-tolerant plant comprising breeding a non-transgenic plant with a transgenic plant comprising the construct of claim 2 , stably incorporated into the genome of the plant, and selecting one or more progeny plants by analyzing for at least a portion of the construct in the selected one or more progeny plants.
