Abstract
The subject invention concerns material and methods useful in the control of pests and, particularly, plant pests. More specifically, the subject invention concerns novel genes and pesticidal toxins referred to as 86A1(b) and 52A1(b). In preferred embodiments, the subject toxins are used for controlling flea beetles of the genus Phyllotreta. Using the genes described herein, the transformation of plants can be accomplished using techniques known to those skilled in the art. In addition, the subject invention provides toxin genes optimized for expression in plants.
Claims29
An isolated protein that has toxin activity against a coleopteran pest wherein said protein has at least 95% identity with the amino acid sequence of SEQ ID NO:
- 5.
An isolated protein that has toxin activity against a coleopteran pest wherein said protein has at least 95% identity with a pesticidally active fragment of SEQ ID NO:
- 5.
An isolated protein that has toxin activity against a coleopteran pest, wherein said protein is encoded by a polynucleotide wherein said polynucleotide hybridizes with the full complement of a nucleotide sequence that encodes the protein of SEQ ID NO:
- 5 when said full complement is used as a hybridization probe, wherein hybridization is maintained at conditions of 0.1% SDS and 2×SSPE at room temperature.
A method for controlling a coleopteran pest wherein said method comprises contacting said pest with a pesticidal protein that has toxin activity against a coleopteran pest wherein said protein has at least 95% identity with the amino acid sequence of SEQ ID NO:
- 5.
A method for controlling a coleopteran pest wherein said method comprises contacting said pest with a pesticidal protein that has toxin activity against a coleopteran pest wherein said protein has at least 95% identity with a pesticidally active fragment of SEQ ID NO:
- 5.
A method for controlling a coleopteran pest wherein said method comprises contacting said pest with a pesticidal protein that has toxin activity against a coleopteran pest, wherein said protein is encoded by a polynucleotide wherein said polynucleotide hybridizes with the full complement of a nucleotide sequence that encodes the protein of SEQ ID NO:
- 5 when said full complement is used as a hybridization probe, wherein hybridization is maintained at conditions of 0.1% SDS and 2×SSPE at room temperature.
