| Research Abstract |
The purpose of this study was to clarify mycorrhizal morpho-types, symbiotic fungi and stable isotopic ratio of green Pyrola japonica that distributes widely in Japan. Roots of P. japonica formed arbutoid mycorrhizas without forming fungal mantles. Molecular identification indicated that symbiotic fungi on the plant were predominated by members of the genus Russula. Based on the stable C isotopic analyses, P. japonicaobtained about 50 % of C derived from associating fungi. These results indicated that P. japonica might depend its partial C sources onto particular fungal symbionts.
