Abstract

Suciatmih. 2015. Diversity of endophytic fungi in mangrove plants on Sampiran Beach and Bunaken Island, North Sulawesi. Pros Sem Nas Masy Biodiv Indon 1 (2): 173-179. Endophytic fungi have been found in nearly all plant families, represented by many species in different climate regions in the world. The research objective was to isolate and identify endophytic fungi which colonize in mangrove plants growing on Sampiran Beach and Bunaken Island, North Sulawesi. Isolation of endophytic fungi was done by direct planting; and the isolates were identified based on morphological characters. The results indicated that 69 isolates of endophytic fungi were isolated from the roots, leaves and twigs of mangrove plants. Of the 69 isolates, 19 isolates (28%) were identified to species level, 21 isolates (30%) to the genus and 29 isolates (42%) were unidentified as no spores were not observed, impeding the microscopic identification. The endophytic fungi isolated belong to group Aspergillus, Colletotrichum, Fusarium, Guignardia, Penicillium, Pestalotiopsis, Phomopsis, Talaromyces and Trichoderma. It could be concluded that mangrove plants growing on Sampiran Beach and Bunaken Island, North Sulawesi were colonized by endophytic fungi. Furthermore, this study also isolated Talaromyces leycettanus from the mangrove plants. This finding might be new information regarding endophytic fungi colonizing in mangrove plants.
