Researchers Discover Non-Bt Protein for Corn Rootworm Control
DuPont Pioneer researchers discovered a protein from a non-Bacillus thuringiensis (Bt) bacterium source that shows insecticidal control of western corn rootworm (WCR) in North America and Europe.
The researchers said that the insecticidal protein, designated IPD072Aa, was isolated from Pseudomonas chlororaphis. Transgenic corn plants expressing IPD072Aa showed protection from WCR insect injury under field conditions. The researchers said the protein could be a critical component for managing corn rootworm in future corn seed product offerings, and suggests that bacteria other than Bt are alternative sources of insecticidal proteins for insect control trait development.
