The complete mitochondrial genome of Claea dabryi (Teleostei, Nemachilinae, Claea)

Abstract

Claea dabryi is a small bottom-dwelling fish that is endemic to the upper stream of the Yangtze River. In this study, we successfully sequenced the first mitochondrial genome of C. dabryi. The mitogenome is 16 569 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region (D-loop). Most of the genes are encoded on the heavy strand, except for eight tRNAs (tRNA^Gln, tRNA^Ala, tRNA^Asn, tRNA^Cys, tRNA^Tyr, tRNA^Ser, tRNA^Glu, and tRNA^Pro) and ND6 gene. In this paper, we utilized 12 protein-coding genes of C. dabryi and other 11 closely species to construct the species phylogenetic tree to verify the accuracy of C. dabryi.
