Insecticidal proteins and methods for their use
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 insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.
1. A DNA construct comprising a heterologous regulatory element and a polynucleotide encoding a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 12, wherein the polypeptide has insecticidal activity against a Coleopteran insect pest.
2. A transgenic plant or plant cell comprising the DNA construct of claim 1 .
3. A method for controlling a Coleopteran insect pest population, comprising contacting the insect pest population with a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 12, wherein the polypeptide has insecticidal activity.
4. A method of inhibiting growth or killing a Coleopteran insect pest, comprising contacting the insect pest with a composition comprising a polypeptide having at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 12, wherein the polypeptide has insecticidal activity.
5. A method for controlling a Coleopteran insect pest population, comprising contacting the insect pest population with the transgenic plant or plant cell of claim 2 .
6. A method of inhibiting growth or killing a Coleopteran insect pest, comprising transforming a plant with the DNA construct of claim 1 , and further comprising contacting the insect pest with the transgenic plant or plant cell.
7. The method of claim 6 , wherein the insect pest is Western Corn Rootworm ( Diabrotica virgifera virgifera ).
8. The method of claim 4 , wherein the insect pest or insect pest population is resistant to at least one Bt toxin.
