Abstract

Plant Conservation Division, Korea National Arboretum, Pocheon 487-821, KoreaABSTRACT: This study was conducted to investigate diversity of orchid endophytic fungi from roots of two terrestrial orchids,Cypripedium japonicum and Cypripedium macranthum in Korea. The endophytic fungi were identified using morphological andDNA sequences isolated from the roots. Totally, 11 taxa of the endophytic fungi were identified from the roots of C. japonicumand 15 taxa from C. macranthum. Three species of the fungi were common in both host species; Leptodontidium orchidicola,Humicola fuscoatra var. fuscoatra, Umbelopsis dimorpha. Six species of the fungal isolates were the first report in Korea;Oidiodendron echinulatum, Pseudogymnoascus roseus, Geomyces vinaceus, Cryptosporiopsis ericae, U. dimorpha, Chaetomiumcupreum.KEYWORDS

Abstract

Department of Biology Education, Korea National University of Education, Chungbuk, 363-791, KoreaABSTRACT: In this study, endophytic fungi were isolated from leaves of four species of woody plants, Acer tagmentosum, Larixkaempferi, Abies holophylla, and Pinus koraiensis, on Mt. Hambaek, Gangwondo, Korea. The endophytic fungi were identifiedusing morphological and sequences analysis of ITS regions. The fungal endophytes were identified as Talaromyces radicus,Myceliophthora verrucosa, Cryptosporiopsis diversispora, and Sphaerulina berberidis, which are the first record in Korea. Themorphological and molecular phylogenetic characteristics of each strain were described.KEYWORDS

Abstract

In this study, orchid mycorrhizal fungi (OMF) were isolated from four terrestrial orchids on Mt. Hambeak, Platnathera chlorantha, Platnathera mandarinorum, Cephalanthera falcate, and Cephalanthera longibracteata. OMF were identified using morphological and sequences analysis of fungal internal transcribed spacer (ITS) regions by specific primer of basidiomycetous orchid mycorrhizas; ITS1-OF and ITS4-OF. Four species of orchid mycorrhizal fungi were identified as Ceratobasidium sp, Epulorhiza anaticula, Tulasnella calospora and Tulasnella sp.
