植物防御系统中抗病相关基因的研究进展 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.
