Abstract

ABSTRACT : Hydrocharis dubia Backer and Salvinia natans All. were sampled from the Junam and Dongpan reservoirs, representative freshwater wetlands of Korea. A total of 19 endophytic fungal strains were isolated from hydrophytes native to the Junam wetlands and 5 strains were isolated from the Dongpan wetlands. Depending on phylogenetic analysis based on internal transcribed spacer (ITS) region, strains from Junam belonged to 11 genera and from Dongpan belonged to 5 genera. Fusarium,Phoma and Talaromyces were commonly distributed genera from two wetlands. The fungal diversity index showed clear differences between each wetlands or each host hydrophyte. Above all, the highest diversity value was observed from Salvinia natans All., which have been reported as promising biological resources as eutrophication controller in environmental ecology.
