Outline of Final Research Achievements

We studied ectomycorrhizal fungi associated with endangered tree species, Pseudotsuga japonica and Pinus amamiana, and found two new host specific fungal species (Rhizopogon togasawariana and Rhizopogon yakushimensis sp. nov.) that were most dominant in soil spore banks. These ectomycorrhizal fungi were not compatible with other local tree species, indicating they would selectively facilitate seedling establishment of the endangered tree species and may potentially contribute to the conservation of these trees. Both Rhizopogon species were rare in ectomycorrhizal roots of resident trees and mainly existed as dormant spores in small geographical areas comparable to their endangered hosts. Thus, the Rhizopogon species we found may also be on the verge of extinction.
