Abstract: Botrytis cinerea,the gray mold fungus,is a broad host-range necrotrophic agent. This necrotrophic fungus adopts diverse virulence strategies to aggress host plants. And correspondingly,defense responses of host plants are multifaceted and genetically quantitative. PTI is the important part of immune responses to B. cinerea. In this review,recent advances in signals eliciting PTI and recognition,transmission of B. cinerea signals,transcriptional factors and epigenetic modifications,plant hormone regulation,resistant cellular events and secondary metabolites are summarized. Elements and methods for applying in gray mold management practices are particularly pointed out,for the purpose of resolving problems resulted from using chemical pesticides only.

Key words: defense responses, molecular mechanisms, the gray mold fungus B. cinerea
