| 摘 要： | 随着越来越多转基因作物的出现，外源基因对普通栽培种和野生近缘种的基因污染以及通过自然杂交发生基因漂移的可能性都在增加。转基因大豆作为世界上种植面积最大的转基因作物，2007年占据了世界转基因作物种植面积的51%。我国野生大豆的种质资源丰富，且每年都要大量引入转基因大豆，这必将带来一系列的生态风险。本文综述了转基因大豆在我国发生基因逃逸并与野生近缘种杂交的可能性以及杂交后可能的生态效应，并提出了今后应开展工作的方向，以期为我国转基因大豆管理提供依据。

| Abstract: | As more transgenic cultivars become available,the contamination of conventional cultivars and wild relatives with transgender and the unintended gene flow through natural crossing will become increasingly probable.Transgenic soybean,the largest transgenic crops in planting area in the world,accounted for 51% of the planting area of worldwide transgenic crops in 2007.The germ plasm resource of wild soybeans in China is very rich while great amount of transgenic soybean was imported every year,which could cause contamination by gene flow from the transgenic soybean to wild relatives.As far as the ecological risk of the transgenic soybean in China is concerned,the authors reviewed the probability of gene flow between transgenic soybean and wild soybeans,and the possible post-hybridization effect was discussed as well.In conclusion,some future directions in this research field were proposed for optimization management of transgenic crops in China. |
