Environment-sensitive genic male sterility is a type of male sterility that is affected by both genetic and environmental factors. Environment-sensitive genic male sterile lines are not only used in two-line hybrid breeding but are also good materials for studying plant-environment interactions. In this study we review the research progress on environment-sensitive genic male sterility in rice from the perspectives of epigenetic, transcriptional, posttranscriptional, posttranslational and metabolic mechanisms as well as signal transduction processes. While significant progress has been made in the genetics, gene cloning and understanding of the molecular mechanisms of environment-sensitive genic male sterility in recent years, the relevant regulatory network is still poorly understood in rice. We therefore also review studies of environment-sensitive genic male sterility in Arabidopsis and other crops, hoping to promote research in this field in rice. Finally, we analyse the challenges posed by environment-sensitive genic male sterility and provide corresponding suggestions. This review will contribute towards an understanding the molecular genetics of environment-sensitive genic male sterility and its application in two-line hybrid breeding in rice and other species.
环境敏感型核雄性不育是一种受遗传和环境因素共同影响的雄性不育类型。环境敏感型核雄性不育系不仅用于两系杂交育种，也是研究植物与环境相互作用的良好材料。在本研究中，我们从表观遗传、转录、转录后、翻译后和代谢机制以及信号转导过程等角度综述了水稻环境敏感型核雄性不育的研究进展。尽管近年来在环境敏感型核雄性不育的遗传学、基因克隆及分子机制解析方面取得了显著进展，但水稻中相关调控网络仍知之甚少。因此，我们还综述了拟南芥和其他作物中环境敏感型核雄性不育的研究，希望推动水稻这一领域的研究。最后，我们分析了环境敏感型核雄性不育带来的挑战并提供了相应建议。本综述将有助于理解环境敏感型核雄性不育的分子遗传学及其在水稻和其他物种两系杂交育种中的应用。
