摘　　要：随着转Bt基因作物的推广和应用 ,其对生态环境及其它方面可能产生的影响越来越受到重视 .加之Bt毒素蛋白检测技术的发展 ,国外学者们围绕纯化毒素蛋白与土壤的相互关系等方面开展了大量研究 ,并取得了一些结果 .本文介绍了转Bt基因作物产生的毒素蛋白的杀虫特性 ,杀虫蛋白的测定方法 ,转Bt基因作物向大田释放存在的潜在风险及土壤矿物质、有机质、有机矿质复合体对纯化Bt毒素存活的影响 ,毒素在根际土壤中的行为等方面的研究现状 .最后 ,提出了今后有关研究中应注意的几个问题 .With the popularization and application of transgenic Bt crops ,and increasing attention has been paid to their potential impact on ecological environment and other aspects.And,as the development of detecting techniques for Bt toxin protein and soil were made by oversea researchers.This paper reviewed the current situation of the studies on the insecticidal characteristics and detecting methods of toxin proteins released by transgenic Bt crops,the potentical risk of their field release,the impact of soil mineral,organic matter and organo mineral complex on the persistence of purified Bt toxins,and the behavior of Bt toxins in rhizospheric soil.Based on our researches,several problems which should be paid attention to in related studies were also pointed out.
