Coastal pine forests in Japan are declining by pine nematode disease and eradicated by a recent Tohoku earthquake needing effective planting techniques to rehabilitate the forests. Japanese black pine associate with ectomycorrhizal fungi that can facilitate nutrient water uptake and alleviate soil salinity.I conducted the present research to clarify ectomycorrhizal community structuresgenetic characterization of a dominant fungal speciesand the response of the species against salinity.Among 8 stands examined, Cenococcum geophilum was the most dominant species irrespective of the stands.Variations in the genetic diversities and the resistance to NaCl were observed among isolates of the species.
