Abstract

In order to understand the molecular insights within the Terebellida, the complete mitochondrial genome of Loimia arborea was sequenced. The mitochondrial genome is 16,023 bp, with 13 protein-coding genes (PCGs), 23 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a non-coding region (D-loop). Notably, two adjacent copies of methionine tRNA genes (trnMs) were detected. The phylogeny of Terebellida was constructed based on 13 PCGs from 13 species, two main clades were strongly supported, i.e., Cirratuliformia (clade A) and Terebelliformia (clade B). And the monophyly of the Terebellidae was restored.

Loimia arborea（多毛目：Terebellidae）的首个完整线粒体基因组及系统发育分析。

为了了解 Terebellida 的分子结构，我们对 Loimia arborea 的完整线粒体基因组进行了测序。线粒体基因组长达 16,023 bp，包含 13 个蛋白质编码基因（PCGs）、23 个转运核糖核酸（tRNA）基因、两个核糖体核糖核酸（rRNA）基因和一个非编码区（D-环）。值得注意的是，发现了两个相邻的蛋氨酸 tRNA 基因（trnMs）拷贝。基于 13 个物种的 13 个 PCGs 构建了脑形目系统发生，其中两个主要支系得到了强有力的支持，即 Cirratuliformia（A 支系）和 Terebelliformia（B 支系）。并恢复了 Terebellidae 的单系性。
