植物抗病基因克隆研究进展

Recent advances in cloning of plant disease resistant gene

随着分子生物学及其相关技术的飞速发展，人们对植物与病原微生物相互作用的分子机制了解得越来越透彻。本文对植物过敏性反应和系统获得抗性作了简要概述，并着重讨论了植物抗病基因克隆的进展，涉及到转座子标签技术、定位克隆技术、染色体步行、染色体登陆等方法和策略，归纳了克隆到的植物抗病基因及其产物结构，概述了这些基因产物所共有的特点，并简要介绍了植物抗病基因工程的进展。

As the development of molecular biology and relative techniques,the molecular mechanism of the interaction of plant and its pathogen is becoming more and more clear. After briefly introducing the subject of Hypersensitive Response (HR) and Systemic Acquired Resistance (SAR), this review provides an overview of the progress in plant disease resistant gene cloning, including the strategy of transposon tagging, map\|based cloning etc. Also provides an overview of the conserved structural components that are predicted in the proteins encoded by plant disease resistant gene. The engineering of plant disease resistant gene is also discussed in this review.\;
