一些抗苏云金杆菌毒素的昆虫的抗性是和毒素结合钙粘蛋白的断裂相关。

Resistance to Bt toxins in some insects is linked with mutations that disrupt a toxin-binding cadherin protein.

突变体在毒素作用下，具有较强的防御酶活性，而细胞内膜系统破坏较小则是产生较强抗性的原因。

The mutant under the action of toxin has the ability to increase the defensive enzyme activity and to reduce the damage of cell membrane system that would result in resistance increasing.

近年来，关于溶细胞毒素分布、分类、杀虫机理、昆虫抗性等问题的研究已成为新的热点。

In these years, some problems about distribution, classification, mechanism and resistance of cytolytic toxin are becoming new hotspots.

This is one of the biological properties, the naturally occurring properties of plasmids, is that they exist in microbial populations and they confer on them resistance from toxins that would ordinarily kill them.

这就是这类生物学特性之一,它是质粒所具有的自然特性,这些质粒存在于微生物群体中,并赋予微生物抗性,使它们免于被毒素杀死
