摘要
转基因植物可以通过花粉或种子将外源基因扩散到其他植物,从而对生态环境造成潜在的危害。如何降低外源基因的扩散已引起了人们的极大关注。目前降低外源基因扩散的方法主要有叶绿体转化、花粉不育、种子不育、闭花受精、无融合生殖、暂时性控制及转基因缓和等。主要对各种方法的原理和优缺点及目前的使用情况进行综述。
Transgenic plants can transfer foreign genes through pollen or seed to related plant species. This may cause potential harm to ecological environment. How to decrease the gene flow is drawing a growing public attention. The approaches for decreasing the gene flow include chloroplast transformation, pollen sterility, seed sterility, cleistogamy, apomixis, temporal control, and transgenic mitigation. The theoretical basis, advantages and disadvantages, and usage status of these approaches are presented in this review.
