细胞质雄性不育表型及不育机制研究进展

he presence of some unknown and specialized open reading frames (ORFs) withinplant mitochondrial genomes can cause the failure of male gamete production or their abnormalfertilization, which is referred to as Cytoplasmic Male Sterility (CMS). CMS material is of greatvalue in the commercial production of hybrid seeds owing to their sterility effectively reducebreeding costs and enhance hybrid seed purity. With progressive investigations, new CMSmaterials are continuously being created through various means, with several associated sterilitygenes being identified and cloned. Herein, the current research on the evolution of CMS genes isthroughly reviewed, as well as the exploration of common CMS materials and their responsibleCMS genes. The phenotypic characteristics of CMS materials in material-energy metabolism andhormone levels are summarized. Moreover, several hypotheses concerning the molecularmechanisms of CMS are discussed and some new insights are proposed based on the recentempirical evidence. This review aims to assist in integrating the current research on cytoplasmicmale sterility and contributing to more profound theoretical and experimental investigations in the future.
