Recent studies have indicated that arbuscular mycorrhizal fungi (AMF) are able to influence litter decomposition by interacting with the soil fungal community. However, it remains unclear exactly which constituent groups of the soil fungal community respond to AMF during litter decomposition, and in what ways. To better understand this relationship, we investigated the effect of AMF on soil fungal communities in a greenhouse experiment. Our study found that the composition and richness of the fungal community, at higher taxonomical levels (e.g. phyla, order), remained stable across treatments. However, the relative abundance of some key genera including Mycena, Glomerella, Pholiotina, and Sistotrema were significantly affected by AMF inoculation. Soil fungal community structure was also altered by AMF inoculation during the later stages of litter decomposition. Our study provides new insights into understanding the interaction between AMF and soil fungal communities and reinforces the importance of AMF in soil nutrient cycling.

最近的研究表明，丛枝菌根真菌（AMF）能够通过与土壤真菌群落相互作用来影响垃圾分解。但是，目前尚不清楚土壤真菌群落的哪些组成部分在凋落物分解过程中对AMF的反应以及以何种方式发生反应。为了更好地理解这种关系，我们在温室实验中研究了AMF对土壤真菌群落的影响。我们的研究发现，在较高的分类学水平（例如门，次序）下，真菌群落的组成和丰富度在所有处理中均保持稳定。但是，某些关键属的相对丰度包括迈锡纳（Mycena），小球藻（Glomerella），凤梨属（Pholiotina）和硅藻纲（Sistotrema）受AMF接种的影响很大。在凋落物分解的后期，AMF接种也改变了土壤真菌的群落结构。我们的研究为理解AMF和土壤真菌群落之间的相互作用提供了新的见识，并加强了AMF在土壤养分循环中的重要性。
