摘　　要：酚类物质是植物体内重要的次生代谢产物,对病原微生物的侵袭有很好的防御作用。AM真菌能够诱导植物的酚类物质合成,而且这种诱导既是原位的、也是系统的,相关研究已有大量报道。本文对AM真菌原位和系统诱导酚类物质进行了论述,并对系统诱导过程中可能的信号分子(SA、H2O2)进行了评述,最后提出了AM真菌系统诱导酚类物质产生的可能作用机理,进一步明确后续工作中的研究方向。Phenols are important secondary metabolites in plant tissues,and provide well protection against the attacks by pathogenic microbes.Arbuscular mycorrhizal（AM） fungi can induce the biosynthesis of phenols in plants both locally and systematically.Recently,research has been intensively reported on this aspect.In this paper,the localized and systematic induction of phenols by AM fungi is reviewed.The possible signaling molecules（SA,H2O2） in the induction process are put forward,and the putative action model involved in the biosynthesis of phenols induced by AM fungi is further presented.Some research perspectives for the future are also pointed out.
