In this study, we report the complete mitogenome sequence of the polychaete, (Sars, 1851). The circular mitochondrial genome is 15,696 bp in length and has an AT content of 66%. As in other polychaetes, the genome has 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a non-coding region. Gene composition and their order in the mitochondrion are identical to the Terebelliformia mitogenomes. A maximum-likelihood gene tree based on the mitogenome combined with previously published Sedentaria and Errantia mitogenomes revealed that forms a clade with two Terebelliformia species.
在本研究中，我们报道了多毛纲动物（沙蚕属，1851年）的完整线粒体基因组序列。环状线粒体基因组长度为15,696 bp，AT含量为66%。与其他多毛纲动物一样，该基因组有13个蛋白质编码基因（PCG）、两个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因和一个非编码区。线粒体中的基因组成及其顺序与缨鳃虫亚目线粒体基因组相同。基于该线粒体基因组并结合先前发表的定居亚纲和游走亚纲线粒体基因组构建的最大似然基因树表明，[该物种名称缺失]与两个缨鳃虫亚目物种形成一个分支。
