Phylogenetic tree constructed through maximum parsimony method using MEGA 4.0 (Tamura et al. 2007). The sequence obtained from ITS regions of rDNA of Paecilomyces formosus LHL10 and related fungi. The bioactive endophytic fungal strain formed a sub-clade (86% bootstrap support) with Paecilomyces sp. Aspergillus fumigatus was taken as an out-group.
