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.

本研究的目的是阐明壳斗科树木内生菌和根际放线菌的分类地位和拮抗作用。为此，从3种橡树的叶、茎和根中获得分离物。从根和根际土壤中获得了大量的分离物。叶源分离物与根源分离物和土壤源分离物在系统发育上存在差异。所获得的放线菌菌株的拮抗性各不相同，其中17个菌株对栎枯萎病的多个菌株表现出正抗性。
