Abstract: By the specific signal pathway,such as SAR reaction,induced by avirulence genes,the related plant resistance gene families can be highly expressed and can produce various resistant compounds,pathogenesis related proteins inducing resistant proteins.According to the studies of resistant protein sequencing and 3D structure analyses,it is proved that resistant proteins always have some similar and conservative domains,whose feature is applied in PCR amplification for resistance genes.Also,through positional cloning,transposon tagging,some resistance genes have been cloned and been sequenced.A array of experiments demonstrated the interaction between resistant proteins and avirulence factors.So,to sum up,the results can better explain the Gene-for-gene hypothesis or plant resistant mechanisms.

Key words: Plant resistance gene, R protein, Transgene, Defense response mechanism
