Contribution to Identification of Some Fungal Endophytes Associated with the Harsh Ecosystems of Abadan and Ahvaz

In this study, 25 samples containing root, stem and leaf of the asymptomatic, salt- and heat-tolerant plants growing around Abadan and Ahvaz, were collected and their endophytic fungi were isolated on potato-dextrose-agar (PDA). Thirty five isolates were obtained, 11 out of them were selected based on the morphology of sexual and asexual structures for molecular identification. In molecular assay, the identity of representative isolates was determined using the sequence data of ITS-rDNA and GAPDH (for Curvularia isolates). Based on a combination of morphological and molecular data, the representative isolates were identified and described as following; Alternaria chlamydospora, A. phragmospora, Chaetomium olivaceum, Curvularia ahvazensis, Curvularia sp., Fusarium chlamydosporum and Fusarium sp.To the best of our knowledge, these fungal endophytes are here reported from Aeluropus littoralis, Atriplex lentiformis, Carthamus oxyacantha, Salicornia subterminalis and Scirpus maritimus for the first time.
