Molecular Strategies for Decreasing the Gene Flow of Transgenic Plants
降低转基因植物外源基因扩散的分子策略 Molecular Strategies for Decreasing the Gene Flow of Transgenic Plants

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.
