要旨本文	Arbuscular mycorrhizal fungi (AMF) live in roots and soils, but their seasonal dynamics and relationships to soil properties remain unclear. We collected paired root and soil samples of the same Cryptomeria japonica trees every two months for a year and used NGS targeting the SSU rDNA to clarify the seasonality of AMF community. Soil pH, the best predictor of OTU's distribution, showed significant seasonality, but the total P, total C, total N, and C/N ratio did not. The AMF community was not significantly different seasonally but was different between roots and soils in all seasons. OTU richness in roots and soils was not significantly different at each season and across seasons. Glomus and Archaeospora colonized C. japonica roots year-round while others irregularly colonized them. Root and soil AMF communities of C. japonica are dynamically changing to respond to seasonal variations in the microhabitats, reflecting the seasonal alternations of a few dominant AMF taxa.
