is an endangered fish species found in the Buqun Lake of Qinghai-Tibet Plateau. In this study, we determined the complete mitochondrial genome sequence of the S. The circular mitochondrial genome was 16,621 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and a control region (D-loop). The overall base composition is A 30.1%, C 26.9%, G 17.4%, and T 25.6%, with a high A + T content (55.7%). Further, phylogenetic analysis suggested that is closely related to species of , and then clustered into a clade with other Schizothoracinae species. This work provides additional molecular information for studying conservation genetics and evolutionary relationships.
是一种在青藏高原布群湖发现的濒危鱼类物种。在本研究中，我们测定了该物种的完整线粒体基因组序列。环状线粒体基因组长度为16,621 bp，包含13个蛋白质编码基因（PCGs）、22个转运RNA（tRNA）基因、两个核糖体RNA（rRNA）基因和一个控制区（D-loop）。总体碱基组成为A 30.1%、C 26.9%、G 17.4%和T 25.6%，A+T含量较高（55.7%）。此外，系统发育分析表明该物种与某属的物种密切相关，然后与其他裂腹鱼亚科物种聚为一个分支。这项工作为研究该物种的保护遗传学和进化关系提供了额外的分子信息。
