Pesticidal proteins and methods for their use
View Patent ↗Compositions and methods for conferring pesticidal activity to bacteria, plants, plant cells, tissues and seeds are provided. Compositions comprising a coding sequence for a toxin polypeptide are provided. The coding sequences can be used in DNA constructs or expression cassettes for transformation and expression in plants and bacteria. Compositions also comprise transformed bacteria, plants, plant cells, tissues, and seeds. In particular, isolated toxin nucleic acid molecules are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed, and antibodies specifically binding to those amino acid sequences. In particular, the present invention provides for isolated nucleic acid molecules comprising nucleotide sequences encoding the amino acid sequence shown in SEQ ID NO:50-96, or the nucleotide sequence set forth in SEQ ID NO:1-47, as well as variants and fragments thereof.
1. An isolated polypeptide with pesticidal activity, selected from the group consisting of:
a) a polypeptide comprising the amino acid sequence of any of SEQ ID NOs:66, 67, 68, 69 and 205;
b) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence of any of SEQ ID NOs:66, 67, 68, 69 and 205; and
c) a polypeptide that is encoded by any of SEQ ID NOs:17 18, 19, 20 and 204.
2. A composition comprising the polypeptide of claim 1 .
3. The composition of claim 2 , wherein said composition is selected from the group consisting of a powder, dust, pellet, granule, spray, emulsion, colloid, and solution.
4. The composition of claim 3 , wherein said composition is prepared by desiccation, lyophilization, homogenization, extraction, filtration, centrifugation, sedimentation, or concentration of a culture of bacterial cells.
5. The composition of claim 3 , comprising from about 1% to about 99% by weight of said polypeptide.
6. A method for controlling a lepidopteran, coleopteran, nematode, or dipteran pest population comprising contacting said population with a pesticidally-effective amount of the polypeptide of claim 1 .
7. A method for killing a lepidopteran, coleopteran, nematode, or dipteran pest, comprising contacting said pest with, or feeding to said pest, a pesticidally-effective amount of the polypeptide of claim 1 .
8. A method for producing a polypeptide with pesticidal activity, comprising culturing a host cell comprising a nucleic acid molecule encoding the polypeptide of claim 1 under conditions in which the nucleic acid molecule encoding the polypeptide is expressed.
9. A fusion protein, wherein said fusion protein comprises a polypeptide selected from the group consisting of:
a) a polypeptide comprising the amino acid sequence of any of SEQ ID NOs:66, 67, 68, 69 and 205;
b) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence of any of SEQ ID NOs: 66, 67, 68, 69 and 205; and
c) a polypeptide that is encoded by any of SEQ ID NOs: 17, 18, 19, 20 and 204.
