Abstract

|
|
|
Endophytic fungi were isolated from the roots of halophytes, Suaeda japonica and Carex scabrifolia in the Suncheonbay. The ITS region in rDNA of 15 endophytic fungal strains were amplified using PCR with universal primers ITS1 and ITS4, and those amplified fragments were sequenced. Based on ITS sequence, five fungal genera were identified in S. japonica and seven fungal genera were identified in C. scabrifolia. The Shannon's diversity index (H') of endophytic fungi isolated from S. japonica and C. scabrifolia was 1.561 and 1.889, respectively. In phylogenetic analysis, it was shown that Ascomycota and Pezizomycotina was widely distributed both in S. japonica and C. scabrifolia. Also, Sordariomycetes, Dothideomycetes and Eurotiomycetes were shown to be distributed in these halophytes used in this experiment.
