营养期杀虫蛋白(vegetative insecticidal proteins,VIPs)是苏云金杆菌(Bacillus thuringiensis,Bt)在对数生长中期分泌的一类新型杀虫毒蛋白。本文简述了芽孢杆菌属(Bacillus)中的新型活性杀虫蛋白营养期杀虫蛋白VIPs及其编码基因的发现、特性、作用模式等研究进展。
Vegetative insecticidal proteins (VIPs) are a new class of insecticidal proteins secreted by Bacillus thuringiensis (Bt) in the middle of logarithmic growth phase. This article briefly reviews the progress in the discovery, characterization and mode of action of VIPs encoding novel active insecticidal proteins in Bacillus and their encoding genes.
