水稻隐性核雄性不育基因研究进展及育种应用探讨

水稻隐性核雄性不育材料在杂交育种和水稻生产上都具有十分重要的意义。但是,由于缺乏有效的保持和繁殖技术体系,该类不育材料一直未能在生产上获得充分利用。而现代分子与生物技术的快速发展为这些隐性核雄性不育基因的有效利用提供了机会。综述了目前已克隆的水稻隐性核雄性不育基因的研究进展,并总结了玉米、番茄和拟南芥等材料中存在的隐性核雄性不育基因。我们期望利用这些基因信息和新的生物技术手段(例如定点突变技术),创制更多的水稻不育基因,同时利用新的基因工程手段——种子生产技术(SPT)体系,并结合传统的育种方法,有效地解决水稻隐性核雄性不育系的保持和繁殖难题,开创新的杂交育种途径,拓宽水稻杂种优势的利用空间。

Research Progress and Breeding Application of Recessive Genic Male Sterility Genes in Rice

The recessive genic male sterility(RGMS) materials play an important role in hybrid breeding and rice production.However,these materials have not been fully utilized because of unavailable strategies and technology systems to maintain and reproduce these lines.The rapid development of molecular and biological technology provides opportunities to utilize RGMS genes.This review focuses on the research advances of rice RGMS genes and summarizes those RGMS genes in maize,tomato and Arabidopsis.Hopefully,we can obtain more rice RGMS genes by using bioinformatics and new bio-technology methods(e.g.,targeted mutation),and can resolve the maintenance and reproduction of RGMS lines effectively and establish a new system for hybrid breeding to enhance utilization of hybridization by combining seed production technology(SPT) with traditional breeding technology in rice.
