Abstract
|
|
|
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 and DNA sequences isolated from the roots. Totally, 11 taxa of the endophytic fungi were identified from the roots of C. japonicum and 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, Chaetomium cupreum.
