Abstract

Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are isolated insecticidal proteins and nucleic acids. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest, as probes for the isolation of other homologous (or partially homologous) genes. The insecticidal proteins find use in controlling or killing lepidopteran, coleopteran, dipteran, fungal, hemipteran, and nematode pest populations and for producing compositions with insecticidal activity.

First claim

That which is claimed:

1. An isolated nucleic acid molecule selected from the group consisting of:
(a) a nucleic acid molecule comprising the nucleotide sequence of SEC ID NO: 1;
(b) a nucleic acid molecule which encodes a polypeptide comprising the amino acid sequence of SEC ID NO: 2;
(c) a nucleic acid molecule encoding a protein having insecticidal activity comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 2; and wherein the nucleic acid molecule is operably linked to a heterologous regulatory element.

2. The isolated nucleic acid molecule of claim 1 , wherein said nucleic acid molecule is a synthetic molecule that has been designed for expression in a plant.

3. A DNA construct comprising the nucleic acid molecule of claim 1 .

4. The DNA construct of claim 3 , further comprising a nucleic acid molecule encoding a heterologous polypeptide.

5. A host cell that contains the DNA construct of claim 3 .

6. The host cell of claim 5 that is a bacterial cell.

7. The host cell of claim 5 that is a plant cell.

8. A transgenic plant comprising the host cell of claim 7 .

9. The transgenic plant of claim 8 , wherein said plant is selected from the group consisting of maize, sorghum, wheat, cabbage, sunflower, tomato, crucifers, peppers, potato, cotton, rice, soybean, sugar beet, sugarcane, tobacco, barley, and oilseed rape.

10. Transformed seed of the plant of claim 9 , wherein the seed comprise the DNA construct.

11. A plant having stably incorporated into its genome a DNA construct comprising:
a nucleotide sequence that encodes a protein having insecticidal activity, wherein said nucleotide sequence is selected from the group consisting of:
(a) a nucleic acid molecule comprising the nucleotide sequence of SEQ ID NO: 1;
(b) a nucleic acid molecule which encodes a polypeptide comprising the amino acid sequence of SEQ ID NO: 2; and
(c) a nucleotide sequence encoding a protein having insecticidal activity comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:2; and
a heterologous promoter, wherein said nucleotide sequence is operably linked to the heterologous promoter that drives expression of the nucleotide sequence in a plant cell.
