Abstract:

A set of 44 Chaetomium isolates from Delhi-NCR region were collected and molecularly characterized and confirmed using ITS sequences from NCBI database as C. atrobrunneum, C. brasiliense, C. elatum, C. funicola, C. globosum, C. megalocarpum, C. nigricolor and C. perlucidum. Cluster analysis using maximum parsimony phylogenetic tree for 44 isolates of Chaetomium executed among the six gene regions viz., actin, β-tubulin, calmodulin, ITS, rpb2 and tef-1. The grouping of Chaetomium species using actin appeared either totally or partially heterogenous grouping. Even though with β-tubulin, the isolates of Chaetomium were not grouped in homogenous manner, interspecific diversity was higher in comparison to intraspecific diversity. Total heterogeneous grouping was observed for the Chaetomium species using the calmodulin sequences. Among all the regions studied in this study for grouping the most diversified grouping was observed with rpb2 gene. Better homogeneity was observed even with tef-1 region. But among all ITS was established as the best region for grouping of Chaetomium species.
