Abstract Arbuscular mycorrhizal fungi (AMF) affect multiple ecosystem functions and processes, the assemblages of which vary across ecosystems. However, influences environmental factors on AMF communities may shape these are still largely unknown. In this study, from roots rhizosphere soils Chenopodium ambrosioides in different natural were investigated. The root habitat showed significantly smaller numbers OTUs lower community richness compared to soil habitat. Most shared by same sampling site, indicating that represent a pool species, fraction is recruited plants. habitats Glomeraceae, suggesting recruitment preferences relative contributions explain variations composition phylogenetic structure assessed. results revealed properties predominantly explained variation, followed geographic climate parameters small independently, while host plant few explanations. Overall, our indicated as well characters, especially pH, nitrogen micronutrients (Zn Cu) affected significantly.
