摘要/Abstract

摘要： 水稻脆性突变体是水稻突变类型中较为常见的一类。水稻茎秆强度是一个十分重要的农艺性状,不仅影响水稻的抗倒伏,还影响着水稻的产量和品质。水稻脆性突变体具有纤维素含量低、木质素含量高、营养成分改变和脆性增加等特点,是研究抗倒伏育种的重要材料,也可作为选育谷秆两用型水稻的中间材料。综述了水稻脆性突变体的来源、形成机理和脆性相关基因的定位、克隆及其功能的研究进展,并阐述了脆性突变体在水稻常规育种、转基因育种和谷秆两用稻育种方面的应用。

Abstract: The strength of a rice stem is an important property that affects not only the plant's ability to resist lodging, but also its yield and quality. Commonly found, the rice's brittleness mutant could be used in breeding new grain-and-straw dual-purpose rice varieties. Since it can introduce cellulose-decrase, lignin-increase and/or nutrition-modification on rice plants, it is also important in the studies involving breeding rice for paper-making and forage. The source, formation mechanism, gene-mapping, cloning, functional research of the mutant, as well as its applications in breeding conventional transgenic and grain-and-straw dual-purpose rice are reviewed and discussed in this article.

Key words: Rice, brittle mutant, gene cloning, application
