植物防御系统中抗病相关基因的研究进展

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.

Recent Advances in Research on Disease Resistance Genes in Defence System of Plant

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.
