摘　　要：植物细胞壁是由初生壁、次生壁和中胶层构成的一种细胞结构,对植物正常生长发育至关重要。禾本科植物中的脆性突变体一直以来都被认为是研究植物次生细胞壁形成的优良材料。本文综述了近年来水稻脆性突变体的研究进展,通过对其相关脆性基因的定位、克隆及功能解析,来明确植株机械强度的分子调控机理,以期今后通过分子育种技术进一步提高水稻的抗倒伏、抗逆和抗病虫害能力。The plant cell wall is one kind of cell structures, which is constituted by the primary wall, secondary wall and middle lamella, it is crucial to plants normal growth and development. The brittle mutant in Gramineae plants has been considered excellent materials for studying the formation of plant secondary cell wall. This review briefly summarize the research progress on the brittle rice mutants. We tried to figure out the molecular regulation mechanism of plant mechanical strength by expounding mapping, cloning and function of the genes related to Brittle Culrn （BC） genes, for improving rice lodging resistance, abiotic stress resistance, pest and disease resistance through molecular breeding technology in the future.
