摘　　要：植物细胞质雄性不育(cytoplasmic male sterility, CMS)是由线粒体基因重排产生不育基因,引起植株自身不能产生或释放功能性花粉粒,但可接受外来花粉完成受精并产生后代的现象。随着不同植物中CMS现象的发现,不育相关基因相继被克隆,细胞毒性、能量代谢紊乱、异常程序性细胞凋亡以及逆向调节等CMS分子机制也被提出。本文对植物中已克隆的CMS相关基因以及分子机制进行总结和归纳,以期为今后植物CMS相关研究提供参考。Plant cytoplasmic male sterility(CMS) is caused by sterile genes, which are produced by mitochondrial gene rearrangement. Sterile genes can cause the phenomenon that the plants are incapable to produce or release pollen, but can accept foreign pollen to complete the fertilization and produce offspring. With the discovery of CMS in many kinds of plants, sterility related genes have been cloned. The cytotoxic mechanism, the energy deficiency mechanism, the abnormal programmed cell death mechanism and the retrograde regulation mechanism have been proposed to explain the molecular mechanism of sterility. In this paper, we reviewed the cloned CMS related genes and the molecular mechanism of CMS, in order to provide reference for further research of plant CMS in the future.
