This study describes the first sequencing of the complete mitochondrial genome of , a species of cyprinid snowtrout from the Jialing River and Fujiang River basins in China's Sichuan Province. The total length is 16,571 base pairs. Similar to most Schizothoracinae mitochondrial genomes, there are 37 genes including 13 protein coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. In addition, it contains a control region rich in A-T nucleotides. The overall nucleotide composition is 29.6% for A, 27.1% for C, 17.9% for G and 25.4% for T, and the percentage of GC content is 45.0%. Phylogenetic analysis suggested that and clustered together in a clade. This work provides additional molecular information for studying conservation genetics and evolutionary relationships.
本研究描述了中国四川省嘉陵江和涪江流域鲤科裂腹鱼属一种裂腹鱼完整线粒体基因组的首次测序。其全长为16,571个碱基对。与大多数裂腹鱼亚科线粒体基因组相似，有37个基因，包括13个蛋白质编码基因、22个转运RNA基因和2个核糖体RNA基因。此外，它包含一个富含A - T核苷酸的控制区。总体核苷酸组成中，A占29.6%，C占27.1%，G占17.9%，T占25.4%，GC含量百分比为45.0%。系统发育分析表明，该裂腹鱼与另一种裂腹鱼聚在一个分支中。这项工作为研究裂腹鱼的保护遗传学和进化关系提供了更多分子信息。
