|
Eighty-four endophytic fungal strains were isolated and identified from the roots of halophytes collected in Buan salt marsh. All halophyte samples, such as Suaeda japonica, and Suaeda maritima were isolated from Buan salt marsh. All endophytic fungi isolated were analyzed by sequences of internal transcribed spacer (ITS) containing ITS1, 5.8s and ITS2 region. All endophytic fungi expressed that fungal strains belong to eight orders; Pleosporales (45%), Eurotiales (27%), Incertae sedis (11%), Dothideales (6%), Capnodiales (5%), Hypocreales (5%), and Agaricales (1%). All endophytic fungi were confirmed at the genus level of Ascomycota and Basidiomycota, containing Alternaria, Ascomycota, Aspergillus, Aureobasidium, Cladosporium, Eupenicillium, Fusarium, Gibberella, Hypocrea, Lewia, Macrophoma, Penicillium, Peyronellaea, Phoma, Pleospora, Pleosporales, Pseudeurotium, Schizophyllum, and Talaromyces. Alternaria (21%) and Penicillium (13%) were the dominant endophytic fungal strains. In this study, endophytic fungal strains analyzed from S. japonica and S. maritime, Alternaria (21%), and Penicillium (13%) of Pleosporales and Eurotiales in halophytes were very abundant.
