Arbuscular mycorrhizal fungi are asexual, obligately symbiotic fungi with unique morphology and genomic structure, which occupy a dual niche, that is, the soil and the host root. Consequently, the direct adoption of models for community assembly developed for other organism groups is not evident. In this paper we adapted modern coexistence and assembly theory to arbuscular mycorrhizal fungi. We review research on the elements of community assembly and coexistence of arbuscular mycorrhizal fungi, highlighting recent studies using molecular methods. By addressing several points from the individual to the community level where the application of modern community ecology terms runs into problems when arbuscular mycorrhizal fungi are concerned, we aim to account for these special circumstances from a mycocentric point of view. We suggest that hierarchical spatial structure of arbuscular mycorrhizal fungal communities should be explicitly taken into account in future studies. The conceptual framework we develop here for arbuscular mycorrhizal fungi is also adaptable for other host-associated microbial communities.
丛枝菌根真菌是无性繁殖的专性共生真菌，具有独特的形态和基因组结构，占据土壤和宿主根系这一双重生态位。因此，直接采用为其他生物类群开发的群落组装模型并不合适。在本文中，我们将现代共存和组装理论应用于丛枝菌根真菌。我们综述了关于丛枝菌根真菌群落组装和共存要素的研究，重点介绍了最近使用分子方法的研究。通过解决从个体到群落层面的几个问题，即在涉及丛枝菌根真菌时现代群落生态学术语的应用遇到的问题，我们旨在从以真菌为中心的角度解释这些特殊情况。我们建议在未来的研究中应明确考虑丛枝菌根真菌群落的层次空间结构。我们在此为丛枝菌根真菌建立的概念框架也适用于其他与宿主相关的微生物群落。
