Abstract

The present invention provides novel insecticidal proteins active against a Coleopteran and/or Hemipteran species pest, which include, but are not limited to, TIC3131, TIC3400 and TIC3407 proteins. The present invention also provides a DNA construct comprising operably linked to a heterologous promoter a polynucleotide that encodes the novel insecticidal protein or an insecticidal fragment thereof. The present invention further provides transgenic plants/plant cells/plant parts expressing the insecticidal proteins, methods for detecting the presence of the polynucleotide or the protein in a biological sample, and methods of controlling a Coleopteran and/or Hemipteran species pest using the insecticidal proteins.

First claim

What is claimed is:

1. A DNA construct comprising a polynucleotide operably linked to a heterologous promoter, wherein said polynucleotide encodes an insecticidal polypeptide active against a Coleopteran and/or Hemipteran species pest, wherein said insecticidal polypeptide comprises the amino acid sequence as set forth in SEQ ID NO:2, SEQ ID NO:4, or SEQ ID NO:6.

2. The DNA construct of claim 1 , wherein said polynucleotide comprises a nucleotide sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:19, SEQ ID NO:20 and SEQ ID NO:21.

3. The DNA construct of claim 1 , further comprising a nucleotide sequence encoding at least one other pesticidal agent that is different from said insecticidal polypeptide.

4. The DNA construct of claim 3 , wherein said pesticidal agent is selected from the group consisting of a Cry1A, Cry1Ab, Cry1Ac, Cry1A.105, Cry1B, Cry1C, Cry1D, Cry1E, Cry1F, Cry1G, Cry1H, Cry1I, Cry1J, Cry1K, Cry1L, Cry2A, Cry2Ab, Cry3, Cry3B, Cry4B, Cry6, Cry7, Cry8, Cry9, Cry15, Cry34, Cry35, Cry43A, Cry43B, Cry51Aa1, ET29, ET33, ET34, ET66, ET70, TIC407, TIC431, TIC807, TIC834, TIC853, TIC901, TIC1201, TIC1415, VIP3A and VIP3B protein; said pesticidal agent being toxic to a Coleopteran pest species, a Lepidopteran pest species; or a Hemipteran pest species.

5. A plant cell, plant or plant part comprising the DNA construct of claim 1 , wherein said polynucleotide is modified for use in plants.

6. The plant cell, plant or plant part of claim 5 , wherein said plant cell or plant is selected from the group consisting of alfalfa, banana, barley, bean, broccoli, cabbage, brassica , carrot, cassava, castor, cauliflower, celery, chickpea, Chinese cabbage, citrus, coconut, coffee, corn, clover, cotton, a cucurbit, cucumber, Douglas fir, eggplant, eucalyptus , flax, garlic, grape, hops, leek, lettuce, Loblolly pine, millets, melons, nut, oat, olive, onion, ornamental, palm, pasture grass, pea, peanut, pepper, pigeonpea, pine, potato, poplar, poppy, pumpkin, Radiata pine, radish, rapeseed, rice, rootstocks, rye, safflower, shrub, sorghum, Southern pine, soybean, spinach, squash, strawberry, sugar beet, sugarcane, sunflower, sweet corn, sweet gum, sweet potato, switchgrass, tea, tobacco, tomato, triticale, turf grass, watermelon, and wheat plant cell or plant, and wherein said plant part is a seed, a boll, a leaf, a flower, a stem, or a root.

7. A commodity product produced from the plant cell, plant or plant part of claim 5 , said commodity product comprising a detectable amount of said DNA construct, wherein said commodity product is selected from the group consisting of commodity corn bagged by a grain handler, corn flakes, corn cakes, corn flour, corn meal, corn syrup, corn oil, corn silage, corn starch, and corn cereal.

8. The plant cell, plant or plant part of claim 5 , wherein said polynucleotide is selected from the group consisting of SEQ ID NO:19, SEQ ID NO:20 and SEQ ID NO:21.
