BIODIVERSITY OF THE ENDOPHYTIC FUNGI ISOLATED FROM MORINGA OLEIFERA OF YERCAUD HILLSAbstract
Endophytic fungi residing inside the medicinal plants are of gaining importance for their bioactive compounds. This present study is undertaken to isolate and identify the potential endophytic fungi from Moringa oleifera, a traditional medicinal plant. A total of 24 segments each 12 from leaf and stem were collected, surface sterilized and was inoculated on to Sabouraud Dextrose Agar (SDA) plates. Based on the macroscopic & microscopic features the fungal isolates were identified as Alternaria spp., Aspergillus spp. Bipolaris spp., Exosphiala spp., Nigrospora spp., and Penicillium spp. Many unidentified sterile mycelia forms were also found which were grouped under the class mycelial sterilia. The Colonization Frequency (CF) and Endophytic Infection Rate (EIR) were observed as 91.66% and 45.83% respectively. The results of this study suggest that traditional medicinal plants are a rich and reliable source of novel endophytic fungi. Further studies are required with regard to the screening of these endophytic fungi for the production of novel bioactive compounds which are medically important in the treatment of diseases.
