Abstract: The aim is to study how cytoplasmic male sterility can cause male sterility of plant by affecting the related genes, and how fertility restoring genes in nucleus act on the sterility genes and restoring the fertility. We reviewed the action mechanism and action model of cytoplasmic male sterility, the regulatory mechanism of fertility restoration and the role that restoring genes played in transcriptional and translational level. We pointed out that the research of CMS was not clear due to the influence of various factors, and the action of CMS/Rf model was uncertain on the retrograde regulation of signal in the mitochondria, for some crops, the research of CMS/Rf was in a circle. Therefore, we proposed suggestions on mechanism research and more sterile lines construction.
