Title Fungi isolated from the endorhizosphere of halophytic plants from the Red Sea Coast of Egypt
Source Fungal Diversity
Abstract Endorhizosphere fungi were isolated from roots of halophytic plants collected in the intertidal region (Avicennia marina), salt marshes (Arthrocnemum macrostachum, Halocnemum strobilecium, Limonastrum monopetalum Zygophyllum album and Z. simplex) and salt affected land (Tamarix nilotica, Zilla spinosa and Z. coccineum) of the Red Sea Coast of Egypt. Twenty-three taxa in addition to Mycelia Sterilia and unidentified yeast species were recovered in low numbers. With the exception of Chaetomium hamadae (Ascomycetes) all endophytes were mitosporic taxa. The most common species were Alternaria alternata, Cladosporium cladosporioides and Penicillium chrysogenum. The majority of isolates were of rhizosphere origin, with the reminder being endophytic in origin. Correspondence analysis indicated that some fungi occurred more often on specific hosts. Species of the genus Zygophyllum and individuals of Avicennia marina from different sites co-ordinate closely with colonizing fungi. Alternaria alternata was found to be restricted to species of Zygophyllum, whereas Papulaspora immersa exclusively colonised Limonastrum monopetalum. Alternaria alternata, Chaetomium hamadae, Conoplea olivacea, Conoplea sp., Papulaspora immersa and Trimatostroma sp., were the fastest growing species in culture. The endophyte isolates were able to degrade cellulose, glucose, maltose, pectin, starch, sucrose and xylan. Conversely, tannin repressed the growth of the majority of taxa.
