The complete mitochondrial genome of Semilabeo notabilis (Cyprinidae: Labeoninae) and phylogenetic implications

AbstractSemilabeo notabilis is an Endangered cyprinid fish species in China. In this study, the complete mitochondrial genome of S. notabilis was firstly determined and described. It was 16,599 bp in length and composed by 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region (D-loop). The overall nucleotide composition was 31.9% of A, 15.7% of G, 25.4% of T, and 27.0% of C, with a total of 57.3% A + T content. Phylogenetic analysis suggested that S. notabilis had the closest evolutionary relationship with S. obscurus. The availability of the S. notabilis mitogenome would contribute to further molecular systematics and conservation genetics studies of this species.
