摘 要 ：丛枝菌根（arbuscular mycorrhiza，AM）真菌是植物活体营养专性共生菌，广泛存在于陆地各生态系统中。研究表明，AM真菌与根围促生细菌（plant growth promoting rhizobacteria，PGPR）之间的相互作用，尤其是它们之间的协同作用不仅影响植物养分吸收利用、病原物发生发展、土壤理化特性与生物修复等，而且对于可持续农、林、牧业生产、稳定生态系统都具有十分重要的意义。因此，近年来给予众多关注和研究。综述了AM真菌与PGPR之间的相互影响及其可能的作用机制，以及AM真菌与PGPR协同改善植物营养和生长、协同抑制病原菌、协同修复土壤方面的作用，旨在总结AM真菌与PGPR相互作用的效应与机制方面的最新研究进展，为今后研究发展提供依据。

Abstract:Arbuscular mycorrhizal (AM) fungi inhabit in various terrestrial ecosystems and play important roles in key ecological processes, including nutrient cycling, conservation of soil structure, and enhancement of nitrogen fixation from rhizobia. In many of these processes, AM fungi interact with a wide variety of living organisms. Interactions, especially the synergism between AM fungi and plant growth promoting rhizobacteria (PGPR) not only influence the absorption and utilization of minerals by plants, occurrence and development of plant pathogens, soil physical and chemical properties, and bioremediation, but are of importance in agricultural, forest and pasture production, and ecosystem stabilization. To acquire more beneficial effects, a wide investigation on effective combinations of AM fungi and PGPR was carried out. The aim of this paper was to discuss the effects and mechanisms of interactions between AM fungi and PGPR. Future study perspectives were also given.
