A truncated cryIA(b) gene encoding the active region of the Bacillus thuringiensis δ-endotoxin was expressed in transgenic sugarcane plants (Saccharum officinarum L.) under the control of the CaMV 35S promoter. Genetic transformation was accomplished by electroporation of intact cells. The levels of recombinant toxin were established and biological activity tests were performed against neonate sugarcane borer (Diatraea saccharalis F.) larvae. Transgenic sugarcane plants showed significant larvicidal activity despite the low expression of CryIA(b).
