Abstract:

Autophagy is a process of bulk degradation that occurs in all eukaryotes. Recent reports indicated that autophagy played a vital role during infection of pathogen, and the kind of autophagy involved in changes with pathogen species, defect of autophagy in pathogens resulted in various phenotype, including abnormal conidiation development, conidial germination and sexual reproductive ability, development of appressorium, appressorium turgor generation and pathogenicity. In this paper, the role of autophagy was reviewed in Magnaporthe grisea, Anthracnose and Fusarium graminearum, the relationship of autophagy and pathogenicity were analyzed, suggested that defect of autophagy induced the imbalance of nutrition circulation, affected the physiology of pathogen and then changed the pathology of them. The study in the future should be focused on molecular mechanism of autophagy of pathogen, mitophagy and role of autophagy in interaction of pathogen and host plant.
