The methods of log-correlation distance and mutual information for constructing genome phylogenetic tree of parvoviruses

Abstract

The taxonomy of the parvoviruses has been provided in the VIIIth report of ICTV. In this paper, we use two methods (log-correlation distance and mutual information) analyze the complete genome of the 30 parvoviruses and construct phylogenetic trees based on compositional vectors of DNA sequences or protein sequences. The phylogenetic trees show the parvovirus genomes are separated into two major groups. One group corresponds to the subfamily Parvovirinae, and the other group corresponding to the subfamily Densovirinae. The structures of the trees are mostly consistent with the taxonomy of the VIIIth report of ICTV.
