摘要: Semilabeo obscurus is an endangered fish in China. In this study, the entire mitochondrial genome of S. obscurus was sequenced; it is 16498bp long (GenBank accession number: MG560823) and contains 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and one control region (D-loop). 12 PCGs start with ATG, but COX1 uses GTG as the start codon. In addition, all tRNAs display the typical clover-leaf structure. Phylogenetic analysis revealed that S. obscurus is closely related to Pseudogyrinocheilus prochilus, and then clustered into a clade with other Labeoninae species. This work provides additional molecular information for studying S. obscurus conservation genetics and evolutionary relationships.
