摘要： 本文论述了植物防御系统中抗病相关基因（resistance gene,R基因）的研究进展。列表总结了迄今已克隆的R基因，并将其归为四种不同的类型。综述了不同基因表达产物-R蛋白在细胞中的定位及其相应的功能。此外，还对R基因编码区的多态性、R基因在染色体上排列方式以及R基因的进化与起源等问题进行了讨论。
Abstract:This review comments on recent advances in research of disease resistance genes(R Genes) in defence system of plants.The R genes cloned up to date are summarized and classified roughly into four classes listed in the Table 1.The location and the founction of the R proteins,i.e.,the expressed products of different R genes in the cells are reviewed.In addition,the polymophism of coding region of R genes,the different fashions of R gene arrangement on the chromosomes,and the evolution and origin of R genes are discussed.
