Abstract:

Autophagy is a highly conservative degradation process in the evolution of eukaryotes. It plays an important role in pathogen infection and the process of plants resisting pathogen infection. Pathogens invading plants mainly use hyphae to penetrate through natural orifices or micro-wounds to invade host cells,establish pathogen-host plant interactions,and trigger plant autophagy response. Host plants use autophagy to directly resist pathogens and enhance plant disease resistance. On the other hand,host plants can also participate in other signal transduction events and indirectly defend against pathogen infection. At present,there are few reports on the interaction between plant autophagy and pathogens. Therefore,studies on the interaction between plant autophagy and pathogens,including the interaction between plant and pathogens,how host plants use autophagy to directly defend against pathogen invasion and indirectly defend against pathogen invasion through the crosstalk between autophagy and other signaling pathways,have been summarized in this paper. Herein,the plant signaling molecular networks involved in regulating autophagy were analyzed from the perspective of plant disease resistance.
