摘要: 灰霉病菌(Botrytis cinerea)是寄主范围较广的死体营养型病原微生物,采用多种毒性策略侵染寄主植物,与此相对应,植物进化出多层次的灰霉抗性,在遗传学上呈现数量性状的特征,其中PTI是植物抗灰霉病菌免疫反应的重要组成部分。主要对PTI信号及识别、灰霉病菌信号的传导、抗灰霉转录因子和表观修饰、植物激素的调控、抗灰霉细胞学事件及次生代谢产物等方面取得的最新研究进展作一综述,特别指出具有实践应用潜力的抗病因素和方法,以期解决单一使用化学农药导致的问题。

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
