Abstract

Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for polypeptide toxins produced by Bacillus thuringiensis or having substantial sequence homology to a gene coding for a polypeptide toxin as described herein and expression of the chimeric gene in plant cells and their progeny after integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against certain insect pests and in controlling said insect pests.
