Characterization of the complete mitochondrial genome of the endangered species Schizothorax integrilabiatus.

ABSTRACT: Schizothorax integrilabiatus is an endangered fish species found in the Buqun Lake of Qinghai-Tibet Plateau. In this study, we determined the complete mitochondrial genome sequence of the S. integrilabiatus. The circular mitochondrial genome was 16,621 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and a control region (D-loop). The overall base composition is A 30.1%, C 26.9%, G 17.4%, and T 25.6%, with a high A + T content (55.7%). Further, phylogenetic analysis suggested that S. integrilabiatus is closely related to species of S. plagiostomus, and then clustered into a clade with other Schizothoracinae species. This work provides additional molecular information for studying S. integrilabiatus conservation genetics and evolutionary relationships.
