    摘要:

    以环境敏感雄性不育为核心的两系杂交水稻对于保障我国粮食安全具有重要作用。目前,在水稻中发现了几十个环境敏感雄性不育基因,已对其中一部分基因进行克隆,并对其调控机制进行了详细的研究。本文综述了水稻环境敏感雄性不育的应用和发展,以及RNA代谢、信号转导、转录调控、花粉壁合成和氨基酸代谢等过程调节水稻环境敏感雄性不育的分子机理,最后对水稻环境敏感雄性不育研究存在的挑战进行分析,并提出了相应的对策。

    Abstract:

    Two-line hybrid rice based on environment-sensitive genic male sterility plays an important role in ensuring food security in our country. At present, dozens of environment-sensitive male sterility genes have been found in rice, and some of them have been cloned and their regulatory mechanisms have been studied in detail. In this paper, we reviewed the application and molecular mechanisms of RNA metabolism, signal transduction, transcriptional regulation, pollen wall synthesis and amino acid metabolism of environment-sensitive genic male sterility in rice. Finally, challenges and corresponding countermeasures of environment-sensitive genic male sterility research in rice are also analyzed and proposed.
