Phylogenetic reconstruction of endophytic fungal isolates using internal transcribed spacer 2 (ITS2) region.

Endophytic fungi are inhabitants of plants, living most part of their lifecycle asymptomatically which mainly confer protection and ecological advantages to the host plant. In this present study, 48 endophytic fungi were isolated from the leaves of three medicinal plants and characterized based on ITS2 sequence - secondary structure analysis. ITS2 secondary structures were elucidated with minimum free energy method (MFOLD version 3.
