摘要：

随着稻瘟病抗性基因的不断发掘与分离克隆，抗病基因在水稻基因组遗传图谱和物理图谱的分布及不同类型抗病基因的结构特点逐渐明了。目前鉴定的水稻抗稻瘟病基因主要分布在除第3染色体以外的其余染色体上，其中第11染色体上分布的稻瘟病抗性基因数目至少有24个。此文概述了水稻抗瘟病基因在基因组的分布和抗性基因的结构特点，重点介绍了水稻基因组第11染色体稻瘟病抗性基因的定位、克隆以及抗病基因类似物和抗性基因在该染色体上的分布特点，并对稻瘟病抗性基因在水稻育种中的应用提出了展望。

Abstract:

The distribution and structure characteristics of blast resistance (R) genes on the rice physical and genetic maps have been gradually elucidated, as many blast R genes have been identified and cloned in recent years. These R genes are distributed on all of the rice genome except on chromosome 3.Among them, at least 24 R genes are located on chromosome 11. In this paper, we review the recent research progress on mapping and cloning of blast resistance genes in rice. In particularly, we focus on the distribution and structure characteristics of blast R genes and resistance gene analogues located on chromosome 11. Exploitation and application of new R genes on rice blast resistance breeding by marker aided selection is also discussed.
