The coastal sand-dune plants of eight species; Argusia sibirica, Calystegia soldanella, Elymus mollis, Lithospermum zollingeri, Raphanus sativus, Salsola collina, Zoysia macrostachya, and Zoysia sinica were collected from the Shindu-ri coastal sand dune. Ninety-eight endophytic fungal strains were isolated from the roots of these plants, analyzed, and identified by sequences in their internal transcribed spacers (ITS) at the ITS1, 5.8S, and ITS2 regions. The diversity of endophytic fungi isolated from coastal sand-dune plants was confirmed with various diversity indices. The fungal strains belonged to thirteen orders: Capnodiales (3.09%), Eurotiales (70.10%), Glomerellales (1.03%), Helotiales (3.09%), Hypocreales (9.28%), Mortierellales (2.06%), Onygenales (1.03%), Ophiostomatales (1.03%), Pleosporales (1.03%), Polyporales (1.03%), Russulales (1.03%), Saccharomycetales (2.06%), and Xylariales (1.03%). Of the endophytic fungal strains collected, Penicillium (59.18% in Eurotiales) and Fusarium (5.10% in Hypocreales) were the most abundant in coastal sand-dune plants. The endophytic fungal strains isolated from C. soldanella were more diverse compared to strains from the other coastal sand-dune plants.
