导入外源Bt基因与受体作物次生代谢物质的交互关系研究

转Bt基因作物是目前商品化进程最快的转基因作物之一,外源Bt基因的导入为培育有效控制有害生物的作物品种提供了新的手段,但外源基因的导入一定程度上改变了作物自身的基因序列,可能引起作物的代谢过程发生改变。本文对转Bt基因作物中导入的Bt基因所产生的杀虫蛋白与作物自身次生代谢物质含量及其效应的关系进行简要综述,结果表明基因的改造和重组已经影响到转Bt基因作物的一些代谢过程。

Interaction between exogenous Bt gene and secondary metabolites of crop

With the advent of transgenic plant,exogenous Bt gene utilization has offered effective opportunities for developing new series resistant crop varieties.The presence of foreign genes in transgenic plants causes physiological changes in the plants including changes of secondary metabolism,and these changes could lead to ecological effects on the environment.A train of recent research on secondary metabolite and Bt protein interactions were reviewed in this paper.The results indicate that exogenous genes rebuilding affects secondary metabolism of crops.
