摘　　要：水稻叶色突变是一种肉眼明显可见的性状变异,变异的主要原因是基因突变导致叶绿体缺失、结构异常、叶绿素含量和比例发生改变。叶色变异主要由核基因控制,也可由叶绿体基因或核质互作控制。叶色变异对研究光合作用机制、叶色调控机理、叶片发育调控以及稻作生产应用都具有重要的意义。本文对近年来有关水稻核基因控制的叶色突变的类型及来源、遗传机理、应用前景等进行了综述,重点介绍了叶色突变体的基因定位和功能研究。Rice leaf color mutations are distinct phenotypic variations which are mainly resulted from the loss of chloroplast,structural abnormality of chloroplast,changes of chlorophyll content and distribution.Nuclear genes and chloroplast genes or interactions between them could be responsible for the phenotypic variations.Leaf color mutants therefore are the ideal and important sources for characterization of mechanisms underlying photosynthesis,formation of leaf color,biogenesis of chloroplast,and could apply in rice production.This paper reviews on recent advances in rice chlorophyll deficient mutants with special focus on gene mapping and functional analysis of nuclear-mediated leaf color genes in rice.
