要旨本文	This study aims to clarify AM associations of Cryptomeria japonica in natural forests. We examined community structures of AM fungi at Yakushima Island. Root systems of seedlings and mature trees, and surrounding soils were collected and applied for DNA barcoding targeting the SSU region. These data were correlated with abiotic variables to identify which factors impacted the fungal communities. Results showed that Glomus was the dominant genera in both seedlings and mature trees, and the ASV richness was significantly higher in soil than in root. Community structures of AM fungi were clustered significantly among seedling roots, mature tree roots or soils, and being influence by pH, EC, and C/N. These findings suggest that Glomus species were a dominant taxon associated with natural Japanese cedar trees affected by proximate soil conditions.
