Phylogenetic association of Schizothorax esocinus with other Schizothoracinae fishes based on protein coding genes

Abstract

Whole mitochondrial DNA (mtDNA) for Schizothorax esocinus sequence was found to be 16,591 bp with 13 protein-coding genes, 2 rRNAs genes, 22 tRNA genes, and 2 non-coding region. For estimating phylogenetic association of a species, protein coding genes of mitochondrial DNA are considered to be a great value. In this study, we sequenced protein-coding genes of Schizothorax esocinus, based upon which we compared the 23 Schizothoracinae fishes with S esocinus by phylogenetic association. We analyzed that S. esocinus to be closely associated with Schizothorax labiatus, Schizopyge niger, Schizothorax nepalensis with high-bootstrap values. Such empirical data would be important for understanding the phylogenetic relationship of Schizothorax species.
