Marine annelids are a globally distributed and species-rich group, performing important ecological roles in macrobenthic communities. Yet, the availability of molecular resources to study these organisms is scarcer, comparatively with other phyla. Here, we present the first complete mitogenome of the Atlantic ragworm (OF Muller, 1776). The mitogenome (15,904 bp long) contains 13 protein-coding genes, 22 transfer RNA, and two ribosomal RNA genes, all encoded in the same strand. Gene arrangement and composition are identical to those observed in two available congeneric species, and . The phylogenetic analysis using both maximum-likelihood and Bayesian inference methods reveal a well-supported monophyly of genus and the already reported paraphyletic relationships within the subfamilies Nereidinae and Gymnonereidinae. Our results highlight the relevance of increasing the molecular sampling within this diverse group of marine fauna.
海洋环节动物是一个全球分布且物种丰富的类群，在大型底栖生物群落中发挥着重要的生态作用。然而，与其他门相比，用于研究这些生物的分子资源相对较少。在此，我们展示了大西洋沙蚕（1776年，穆勒命名）的首个完整线粒体基因组。该线粒体基因组（长度为15,904 bp）包含13个蛋白质编码基因、22个转运RNA和两个核糖体RNA基因，均编码于同一条链上。基因排列和组成与两个已有的同属物种中观察到的相同。使用最大似然法和贝叶斯推断法进行的系统发育分析揭示了该属有充分支持的单系性以及沙蚕亚科和裸沙蚕亚科内已报道的并系关系。我们的结果强调了增加这一多样的海洋动物类群分子采样的重要性。
