【摘要】 矮生性是水稻最重要的农艺性状之一。矮秆基因参与水稻一系列的生理、生化过程,水稻矮生性基因的克隆和功能研究,对了解水稻矮秆性状与产量的关系十分重要。通过介绍水稻矮秆基因的类型和概念,对已克隆的水稻矮秆基因按功能分类详细列举了它们的结构、功能与经典遗传学的关系以及在育种上的利用价值。更多还原

【Abstract】 Dwarfism is one of the most important agronomic traits of rice.The genes underlying participate a series of important physiological and biochemical process.Cloning and functional analysis of the dwarfism related genes reveal the mechanisms for high yielding rice production.In the review,the concept of dwarfism and class of dwarf gene of rice were introduced,and the structure,function and relation with classical genetics and breeding values of the cloned genes were summarized.更多还原
