The nemacheilid genus is widely distributed in the Qinghai-Tibet Plateau and its adjacent areas. The complete mitochondrial genome of the loach collected from the Peigucuo Lake was sequenced. The genome was 16,569 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding control region (D-loop). Most of the genes were encoded on the heavy strand, except for and eight tRNA genes. The overall base composition of was 27.8% for A, 28.4% for T, 25.4% for C, 18.4% for G, with a slight A + T rich feature (56.2%). Phylogenetic analyses showed that all species clustered together and formed a sister relationship with . The complete mitogenome data of would provide essential information in understanding phylogenetic relationships among species.
条鳅属广泛分布于青藏高原及其邻近地区。对采自佩古错湖的泥鳅的完整线粒体基因组进行了测序。该基因组长度为16,569 bp，包括13个蛋白质编码基因、22个转运RNA基因、两个核糖体RNA基因和一个非编码控制区（D-loop）。除了 和8个tRNA基因外，大多数基因在重链上编码。 的总体碱基组成为：A占27.8%，T占28.4%，C占25.4%，G占18.4%，具有轻微的A+T富集特征（56.2%）。系统发育分析表明，所有 物种聚集在一起， 与 形成姐妹关系。 的完整线粒体基因组数据将为理解 物种间的系统发育关系提供重要信息。
