Outline of Final Research Achievements

Endophytes are organisms including fungi that asymptomatically infect healthy plant tissues, which have been reported in every plant species examined to date. Recently, fungal endophytes are getting attention as one of the important symbiont of terrestrial plants. To know the dispersal and reproductive mechanisms of endophytes of tree leaves, we surveyed the community structure of culturable fungal endophytes in leaves of Abies firma, Acer japonicum, Camellia japonica, Carpinus japonica, Eurya japonica, and Fagus crenata. In F. crenata, we investigated the fine-scale distribution of endophytic fungal species within the leaves. In addition, we developed polymorphic microsatellite markers for Ascochyta fagi, which is a dominant species in the fungal endophyte community of F. crenata leaves, and investigated the fine-scale distribution of the fungal genotypes in the leaves of F. crenata.
