Bt designer plants

Quick Reference

Transgenic plants (q.v.) with the gene for the toxin produced by Bacillus thuringiensis spliced into their genomes. Bt corn is an example of such a genetically engineered crop, and the Bt toxin kills off its major enemy, the European corn borer. One third of the corn sold in the U.S. is Bt corn. Farmers plant even more Bt soybeans and Bt cotton. See Bacillus, GMO.
