摘　　要：菌根是普遍存在的一种重要的高等植物根系与土壤菌根真菌的共生体,其中分布最为广泛的菌根类型是丛枝菌根(Arbuscular Mycorrhizal,AM)。丛枝菌根真菌(Arbuscular Mycorrhizal Fungi,AMF或AM真菌)是一类能与绝大多数高等植物根系形成共生体的有益微生物,通过与根际土壤和根皮层细胞形成密集的菌丝网,扩大植物根系吸收面积、提高水分利用率、促进矿质营养元素的吸收和利用、改善体内碳氮循环等方面影响植物的初生代谢产物和次生代谢产物;本文综述了丛枝菌根真菌对植物次生代谢产物的影响、作用机制、在生态系统中的作用及其展望。Mycorrhizal is very popular and important symbiosis phenomena between higher plant roots and mycorrhizal fungi in the rhizosphere soil, and the arbuscular mycorrhizal （Arbuscular Mycorrhizal, AM） is one of the most prevalent type of mycorrhizal fungi. Arbuscular Mycorrhizal Fungi（Arbuscular Mycorrhizal Fungi, AMF or AM fungi） is a kind of the beneficial microbial, which can form symbionts with the majority of higher plant roots. AM fungi can form a dense filament network with the rhizosphere soil and root cortical cells. It not only influence the primary metabolism of the host plant, but also influence the plant secondary metabolism by enlarging the absorption area of the plant roots, improving the water use efficiency, promoting the absorption and utilization of the mineral nutrition elements, improving the Carbon and Nitrogen cycle. This review introduced the effects, research situation of arbuscular mycorrhizal fungi on plant secondary metabolism, and the role and application potential of the ecological system.
