摘要
转基因作物释放可能导致潜在的生态风险性,其中一个重要方面是通过花粉传播,将外源基因(如抗除草剂、抗虫基因)转入野生近缘种或近缘杂草而产生难以控制的“超级杂草”。本文讨论了防止外源基因逃逸的几种分子技术手段,主要包括:⑴母系遗传法(又称细胞质遗传法);⑵雄性不育法;⑶种子不育法;⑷染色体组特异性选择法等。
The release of transgenic crops may rise to potential ecological risks, one of which is that sometransgenes(e.g. herbicide-resistant genes and insect-resistant genes) would spread into related weeds or wildspecies by pollination, turning them into uncontrollable 'superweeds'. This minireview describes some mo-lecular strategies for control transgenes escape, including maternal inheritance, male sterility, seed sterility, andincompatible genomes.
