Abstract

Abstract: The Gymnocypris chui, a new recorded species in Lange Lake, was grouped into genus Gymnocypris 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 G. chui 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 tRNA Pro . The 12S rRNA and 16S rRNA located between tRNA Phe and tRNA Leu and were separated by tRNA Val . 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 ( tRNA Cys ) to 76 ( tRNA Lys and tRNA Leu ) in length. To further explore the phylogenetic relationship of the G. chui, we constructed the phylogenetic tree and verified that the G. chui was a part of genus Gymnocypris and had closer relationship with Gymnocypris dobula and was independent from other species of Schizothoracinae, Barbinae and Labeoninae in Cyprinidae. This study provided the valuable evidence on phylogenetic relationship of the G. chui at the molecular level and essential resource for further research on this species.
