两系法杂交水稻(Oryza sativa)的核心是光温敏核不育系,近年来对光温敏核不育系的研究取得了巨大进展。本文概述了光温敏雄性核不育基因的定位与克隆、育性转换机理、不育分子机制以及光温敏核不育的表观调控新进展,并对光温敏核不育的表观遗传学研究前景进行展望,以期为两系杂交水稻育种提供理论指导。 Two lines of hybrid rice (Oryza sativa) is the core of the photo-thermo-sensitive genic male sterile line, in recent years, the thermo-sensitive genic male sterile line made great progress. In this paper, the location and cloning of photosynthetic thermo-thermo-sensitive genic male sterility gene, the mechanism of fertility transformation, the molecular mechanism of sterility, and the new progress in the apparent regulation of photo-thermo-sensitive genic male sterility were reviewed. Genetics research prospect prospects, with a view to provide theoretical guidance for two-line hybrid rice breeding.
