| Research Abstract |
The aim of this study was to clarify taxonomic identity and fungal antagonistic of endophytics and rhizospheric actinomycetes associated with the Fagaceae trees. For this purpose, isolates were obtained from leaves, stems and roots of 3 oak trees species. Larger numbers of isolates were obtained from roots and rhizospheric soils. Isolates originated from leaves were phylogenetic ally different from ones from roots and soils. Fungal antagonistic of obtained actinomycetes isolates were varied, and 17 out of 460 isolates showed positive resistances against multiple isolates of Japanese oak wilt pathogen, Raffaelea quercivora.
