摘要: 简述了稻瘟病抗性的两种类型,着重阐述了稻瘟病主效抗性基因的分子定位和克隆的研究进展,概述了主要分子标记的种类及其特点,分析了图位克隆法在克隆植物抗病基因中的应用,对其存在的技术瓶颈进行了探讨,并指明了克服这些技术难点的途径。

Abstract: In this review, two types of rice blast resistance were elucidated. The advance on the molecular localization and cloning of major blast resistance genes were focused on. The main types of molecular markers and their characters were also introduced. The positional cloning of rice blast resistance genes and the obstacles in this method were discussed. To overcome the difficulties in the positional clone strategy, a useful way was put forward in this paper.
