Abstract
The Botia superciliaris is endemic to China and distributed mainly in the upper reaches of the Yangtze River. The complete mitochondrial genome was 16,597 bp in length, which contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 displacement loop (D-loop) locus. Except for the ND6 gene and eight tRNA genes, all other mitochondrial genes were encoded on the heavy strand. The overall nucleotide composition was 31.6% A, 25.5% T, 27.2% C and 15.7% G, with an AT content of 57.1%. The gene composition and the structural arrangement of the B. superciliaris complete mtDNA were identical to most of the other vertebrates. The molecular data here we presented could play a useful role to study the evolutionary relationships and population genetics of Cobitidae fish.
