The root-associated microbiome is a key determinant of soil nutrient availability, plant biomass productivity and pollutant degradation, but could not be examined in depth prior to recent advances in high-throughput sequencing and bioinformatics. Plant root-associated microbiome refers here to the whole community of bacteria and fungi living on the surface and/or inside plant roots. Arbuscular mycorrhizal fungi (AMF) constitute a widespread soil fungal group that establishes symbiotic associations with the majority of vascular plants. Once AMF colonize plant roots, they develop an extraradical hyphal network, promote nutrient uptake, in particular phosphorus and nitrogen, and protect plants against soil-borne pathogens. As fungi that extend their hypha into the rhizosphere and the surrounding soil, AMF not only interact with plants, but also with a myriad of soil microbes. Several

根相关微生物组是土壤养分供应、植物生物量生产力和污染物降解的关键决定因素，但在高通量测序和生物信息学的最新进展之前，无法对其进行深入研究。植物根相关微生物组在此是指生活在植物根表面和/或内部的细菌和真菌的整个群落。丛枝菌根真菌（AMF）是一个广泛分布的土壤真菌类群，与大多数维管植物建立了共生关系。一旦AMF定殖于植物根部，它们就形成根外菌丝网络，促进营养吸收，特别是磷和氮，并保护植物免受土传病原体的侵害。作为将菌丝延伸到根际和周围土壤的真菌，AMF不仅与植物相互作用，而且与无数土壤微生物相互作用。几
