摘要

The production of hybrid seeds in Chinese cabbage (Brassica rapa) is a critical aspect of agricultural biotechnology, often facilitated through the use of male sterility lines to harness heterosis. Despite the significance of this approach, the molecular mechanisms of male sterility in Chinese cabbage remain elusive. Genetic male sterility (GMS), as opposed to cytoplasmic male sterility (CMS), offers distinct advantages such as complete sterility without adverse cytoplasmic effects and the potential for restoring the original genetic makeup. These attributes render GMS particularly promising for practical applications in crop production. In this review, we provide a comprehensive overview of the current research on GMS materials and associated genes in Chinese cabbage. Further, by integrating knowledge from Arabidopsis GMS genes, we identified and discussed the putative orthologs in Chinese cabbage. The continued investigation into GMS genes will enhance our comprehension of the molecular mechanisms governing male fertility and significantly bolster the utilization of heterosis in Chinese cabbage.
