Outline of Final Research Achievements

We examined communities of mycorrhizal fungi in the Pinus luchuensis forests in the two islands, Iriomote-jima (continent island) and Daito-Jima (marine island). Fifty soil samples from each island were gathered. Into the soil the seeds of the pine were planted and nursed. By using the base sequence of the ITS region of rDNA, Suillus granulatus was detected with high frequency in both islands. Meanwhile, while the non-wind dispersal mycorrhiza Rhizopogon sp. and Cenococcum geophilum are detected in Iriomote, they were not detected in the Daito Island. This meant in the Daito Island, an oceanic island, non-wind dispersal mycorrhizal fungi could not be invaded.
