Research advances in species diversity of arbuscular mycorrhizal fungi.
丛枝菌根真菌物种多样性研究进展

Arbuscular mycorrhizal (AM) fungi are one of the important components of biodiversity in ecosystems. They are rich in species diversity, genetic diver sity, and function diversity. Their taxonomy position moved forward to phylum, a nd there are 214 species belonging to 19 genera, 13 families, 4 orders, and 1 cl ass reported in the world. AM fungi play a vital role in keeping ecological bala nce and enhancing ecosystem sustainable productivity. This paper reviewed the re search advances in the species diversity of AM fungi distributed globally, the k ey factors affecting this species diversity in various ecosystems, and related r egulation pathways. It was considered that molecular biological techniques would be the main approaches in the future study of AM fungal species diversity.
