A primary studies on molecular taxonomy of Trametes species based on the ITS sequences of rDNA

Some species of the genus Trametes are so similar in morphological characteristics that it’s difficult to identify and separate these species based on traditional taxonomy. In this study, the ITS sequences including 5.8S gene from 34 Trametes strains were determined and used to construct a phylogenetic tree for phylogenetic analysis together with 17 reference sequences obtained from the GenBank database. The phylogenetic tree indicated that the Trametes group was separated from other groups and most strains of Trametes versicolor formed a single clade with a high percentage support. Furthermore, the strains of T. hirsuta and T. pubescens classified by traditional taxonomy clustered together in a highly supported clade according to the tree, which strongly implied that T. hirsuta and T. pubescens should be the same species.
