Abstract: Plant pathogenic genes in the process of pathogen determine the infection of the pathogenic genes with a parasitic plant and plant damage normal physiological function, the regulation of plant taxis,adsorption, invalion,colonization, expansion, destruction of the host, realistic models of pathology and significant process. Recognition of products encoded directly or indirectly by avirulence genes with products encoded directly or indirectly by resistance gene induced hypersensitive reactions and other necrosis host resistance response,Further study on the pathogenic gene and avirulence gene,facilitates the study of pathogen host interaction,so as to provide evidence for effective disease control measures. Avirulence genes, pathogenicity genes and gene expression and regulation characteristics of the study were reviewed in this study.

Key words: Avirulence genes, Pathogenicity genes, Pathogens
