The complete mitochondrial genome of the (Cypriniformes: Cyprinidae).

The , a new recorded species in Lange Lake, was grouped into genus in Schizothoracinae, and had the rare quantity and limited resources on biology and genetics, especially in the mitochondrion. In this study, the complete mitochondrial sequence of was assembled and phylogenetic relationships with other species in Cyprinidae were analyzed. The whole mitochondrial sequence was 16,864 bp in length, which contained two control regions (D-loop regions), two rRNA genes (12S and 16S rRNA), 13 protein-coding genes and 22 tRNA genes. The D-loop region was separated by . The 12S rRNA and 16S rRNA located between and and were separated by . The 13 mRNAs had three start codons, five termination codons and four overlap regions. The 22 tRNA scattered among the whole mitochondrion, and they were range from 66 ( ) to 76 ( and ) in length. To further explore the phylogenetic relationship of the , we constructed the phylogenetic tree and verified that the was a part of genus and had closer relationship with and was independent from other species of Schizothoracinae, Barbinae and Labeoninae in Cyprinidae. This study provided the valuable evidence on phylogenetic relationship of the at the molecular level and essential resource for further research on this species.
