Abstract
Hemiculterella sauvagei, a Chinese minnow endemic to the upper Yangtze River, is an important part of the aquatic ecosystem and plays a vital ecological role in maintaining aquatic biodiversity. In this study, we provide the first mitochondrial genome of H. sauvagei. The complete mitochondrial genome of H. sauvagei is 16618 bp in length, containing 13 protein-coding genes, two rRNA genes (12 S and 16 S rRNA), 22 tRNA genes and a non-coding control region (D-loop). The gene nucleotide composition of H. sauvagei is A = 29.9%, T = 27.0%, C = 17.4% and G = 25.6%, with a slight AT bias of 56.9%. The complete mitochondrial genome of H. sauvagei would be useful for further studies on genetic diversity and molecular phylogenetic relationship of the subfamily Cultrinae.
