Abstract

|
Native halophytes, such as Suaeda maritima, Limonium tetragonum, S. japonica, Zoysia sinica, and Phragmites australis were collected from the Muan salt marsh. Ninety endophytic fungi were isolated from the roots of the collected halophytes. Molecular insights inferred by internal transcribed spacer containing ITS1, 5.8s, and the ITS2 region showed that all the fungal strains belong to ten orders, i.e., Capnodiales (4.44%), Cystofilobasidiales (1.11%), Dothideales (3.33%), Eurotiales (53.33%), Glomerellales (3.33%), Hypocreales (8.89%), Mucorales (1.11%), Pleosporales (15.56%), Sordariales (1.11%), and Trichosphaeriales (1.11%). The rest (6.67%) of all fungal isolates were not identified. Ninety fungal strains were confirmed at the genus level, containing Acremonium, Alternaria, Aspergillus, Aureobasidium, Cephalosporium, Chaetomium, Cladosporium, Colletotrichum, Cryptococcus, Didymella, Dothideomycete, Emericellopsis, Epicoccum, Eupenicillium, Fusarium, Gibberella, Gongronella, Macrophoma, Microsphaeropsis, Nigrospora, Paecilomyces, Paraconiothyrium, Penicillium, Phaeomyces, Phoma, Pleosporales, Purpureocillium, and Talaromyces. Of all the endophytic fungi identified from the various halophytes, Aspergillus and Penicillium of Eurotiales had the highest abundance.
