is a recently described caryophyllidean monozoic tapeworm from schizothoracine fish on the Tibetan Plateau. In the present study, the complete mitochondrial genome of is determined for the first time. The mitogenome is 15,034 bp in length with an A+T content of 59.6%, and consists of 12 protein-encoding genes, 22 tRNA genes, two rRNA genes, and two non-coding regions. The secondary structure of tRNAs exhibit the conventional cloverleaf structure, except for and , which lack DHU arms. The anti-codon of in the mitogenome of is TCT. The two major non-coding regions, 567 bp and 1428 bp in size, are located between and , and , respectively. The gene order of shows a consistent pattern with other caryophyllideans. Phylogenetic analysis based on mitogenomic data indicates that has a close evolutionary relationship with tapeworms and .
是一种最近在青藏高原裂腹鱼类中发现的叶形单殖绦虫。在本研究中,首次测定了其完整的线粒体基因组。该线粒体基因组长度为15,034 bp,A+T含量为59.6%,由12个蛋白质编码基因、22个tRNA基因、两个rRNA基因和两个非编码区组成。tRNA的二级结构呈现出传统的三叶草结构,但缺少DHU臂。其线粒体基因组中 的反密码子为TCT。两个主要的非编码区大小分别为567 bp和1428 bp,分别位于 和 、 和 之间。 的基因排列顺序与其他叶形绦虫一致。基于线粒体基因组数据的系统发育分析表明, 与绦虫 和 具有密切的进化关系。
