摘要: 大多数水稻斑点叶突变体是研究稻瘟病抗性、白叶枯病抗性以及植物程序性细胞死亡机理的理想材料。已经阐明了49份水稻斑点叶突变体的遗传模式,并成功克隆分离了若干斑点叶基因。综述了这些突变体的来源、遗传模式、基因定位和克隆,基因的功能以及它们对水稻主要病害的反应。

Abstract: Many rice spottedleaf mutants are ideal sources for understanding the mechanisms involved in blast resistance, bacterial blight resistance and programmed cell death in plants. The genetic controls of 49 spottedleaf mutants in rice have been characterized and a few couple of spl/Spl genes have been isolated as well. This article reviews on the origin, genetic modes, isolation and characterization of spottedleaf genes responsible for their phenotypes, and their resistance responses to main rice diseases.

Key words: rice, spottedleaf, mutagenesis, disease resistance, programmed cell death
