| Abstract: | With the planting of commercialized transgenic Bt crops in a large scale, it is significant for assessing ecological risk of transgenic crops to study the potential effects of bt toxin protein on soil ecosystem. In this paper, advances in research on effects of rhizosphric soil ecosystem by transgenic Bt crops were reviewed, including the persistence characteristics of toxin protein, the utilization and the biodegradation of toxin protein by soil microbes,and their effects on rhizosphric soil organisms and enzyme activities. Several suggests for future study were also put forward. |
