INSECT-RESISTANT TRANSGENIC PLANTS AND METHODS FOR IMPROVING δ-ENDOTOXIN ACTIVITY AGAINST TARGET INSECTS

摘要

Disclosed are methods for increasing the activity of B. thuringiensis δ-endotoxins against Coleopteran insect pests. Also disclosed are methods for mutagenizing nucleic acid sequences encoding these polypeptides, and increasing insect resistance in transgenic plants expressing these genes.
