The complete mitochondrial genome organization of Schizothorax Plagiostomus (Teleostei: Cyprinidae) from Northern Pakistan

Abstract

Schizothorax plagiostomus, a fresh water fish, is an economically important fish of Pakistan. In this study, the complete mitochondrial DNA (mtDNA) sequence of S. plagiostomus was explored. The mitogenome length was found to be 16 563bp with 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 2 non-coding regions: origin of light-strand replication (O_L) and control region (D-loop). All genes were encoded on the heavy strand except ND6 and few tRNA genes. The overall base composition of S. plagiostomus of the heavy strand was T 25.5%, C 27.0%, A 29.8% and G 17.8%, A + T content 55.3% and G + C content 44.7%. The phylogenetic tree suggests that S. esocinus, S. progastus, S. richardsonii and S. plagiostomus may have closer affinities than other fish of the genus Schizothorax. This mitogenome sequence would be useful for phylogenetic analysis and conservation of this species in Pakistan.
