ABSTRACT : Backer and 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. , and 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 All., which have been reported as promising biological resources as eutrophication controller in environmental ecology.
