摘要:
Disclosed are nucleic acid segments comprising synthetically-modified genes encoding modified Coleopteran-toxic B. thuringiensis Cry 3Bb* &dgr;-endotoxins. Also disclosed are methods of using these genes for preparing a Coleopteran-resistant transgenic plant and reducing insect in restations, and plants thereby produced.
摘要:
Disclosed are methods for increasing the activity of B. thuringiensis .delta.-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.
