| Summary: | Cytochrome B (Cyt B) gene and control region of mitochondrial DNA are considered important for evaluating phylogenetic association of a species. In this study, we sequenced Cyt B and control region of Schizothorax plagiostomus and constructed phylogenetic association tree of S. plagiostomus with 23 schizothoracine fishes. We found S. plagiostomus to be closely associated with S. labiatus, S. richardsonii, S. progastus, and S. esocinus, with high-bootstraps values. Several conserved sequence blocks were identified within D-loop sequences. These are highly conserved within genus Schizothorax compared to other. This study reports the phylogenetic position of the S. plagiostomus among schizothoracines fishes and organization of D-loop region in S. plagiostomus from Pakistan.
