The quality of green tea is influenced by soil microbes in addition to soil conditions and the Camellia sinensis cultivar. Arbuscular mycorrhizal (AM) fungi can significantly improve soil quality and crop productivity; however, the specific AM fungal groups that affect the catechin quality index (CQI) of green tea are not yet clear. In the present study, rhizosphere soil samples, root samples, and fresh tea leaves from six different Camellia sinensis cultivars in Hunan Province, China, were collected. The taxonomic diversity and community composition of AM fungi in the rhizosphere soil and roo...
