摘　　要：近年来,我国在菌根分子生物学、菌根营养学、菌根分类学和菌根生态学等方面取得了令人瞩目的研究成果,其中对丛枝菌根真菌(AMF)的研究居多。AMF能与大部分陆地植物根系形成共生关系,促进植物生长发育,提高植物抗逆性,在保持生态平衡、保护生态环境等方面发挥重要作用。本文主要从非生物胁迫(干旱胁迫、重金属污染、盐碱胁迫)和生物胁迫(致病菌和线虫侵染)方面介绍了AMF在植物根际逆境中发挥的生态功能及作用机制,提出了该研究领域尚存的不足之处和研究前景,为AMF后续研究提供参考。In recent years,Chinese scientists have made remarkable achievements in on mycorrhizal molecular biology,nutrition,taxonomy,and ecology,with arbuscular mycorrhizal fungus(AMF)having been mostly studied.AMF can form symbiotic relationship with roots of most terrestrial plants,promote plant growth and development,improve plant stress resistance,maintain ecological balance,and protect ecological environment.This review mainly introduced the ecological function and mechanism of AMF in plant rhizosphere stress from the aspects of abiotic(drought stress,heavy metal pollution,saline-alkali stress)and biotic stresses(pathogenic bacteria and nematode infection).We proposed the remaining deficiencies and research prospects in this field to provide refe-rence for future research of AMF.
