title: [Recent advances in research on disease resistance genes in defence system of plant].
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 function of the R proteins, i.e., the expressed products of different R genes in the cells are reviewed. In addition, the polymorphism 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.
