Endophytic fungi are eukaryotic organisms that live inside plant tissues with symbiotic association and they have been recognized as a valuable source of novel bioactive metabolites, antibiotics, anti-cancerous compounds, antioxidants, enzymes, vitamins, and pigments. In the present investigation endophytic fungi were isolated from Tephrosia purpurae from Eastern Ghats and near the Bay of Bengal for the first time. Seventy two endophytic fungi with different morphologies were isolated from the leaves, stems and roots of Tephrosia purpurea with colonization rates of 16.5%, 12.5%, and 7%, respectively. Furthermore Biodiversity of endophytic fungi in various segments of the plant were determined by statistical analysis Simpson index (1-D), Shannon-wiener index (Hs) and Species richness (R1).
