The complete mitochondrial genome of Izuka (Annelida: Polychaeta) was presented, which is a circular molecule of 15,930 bp nucleotides. It encodes 37 genes, including 13 PCGs, 22 tRNAs, and two rRNAs. The length of non-coding regions is 1428 bp, and the longest one (1346 bp) is speculated as the control region, which is located between and and is longer than most species in . The complete mitogenome of . Izuka consists of 31.2% A, 23.6% C, 12.9% G, and 32.2% T, which has T vs. A skew (-0.02) and C vs. G skew (-0.29), respectively. Phylogenetic analysis indicates the classification status of Izuka and the relationship with other species in , which is closer with and (bootstrap = 100). By comparisons, the gene arrangement of Izuka and other seven species in are identical and they also cluster together in phylogenetic tree with higher support rate, which indicates the conservativeness between gene arrangement and phylogenetic analysis in . In conclusion, the complete mitochondrial genome of Izuka can provide supportive data for further molecular and evolutionary analysis of .
本文公布了伊豆卡蚓（环节动物门：多毛纲）的完整线粒体基因组，它是一个由15,930个碱基对组成的环状分子。它编码37个基因，包括13个蛋白质编码基因、22个转运RNA和两个核糖体RNA。非编码区长度为1428个碱基对，最长的一段（1346个碱基对）被推测为控制区，位于[具体位置1]和[具体位置2]之间，且比[某分类群]中的大多数物种更长。伊豆卡蚓的完整线粒体基因组由3个部分组成，其中腺嘌呤（A）占31.2%，胞嘧啶（C）占23.6%，鸟嘌呤（G）占12.9%以及胸腺嘧啶（T）占32.2%，其T与A的偏差为（-0.02），C与G的偏差分别为（-0.29）。系统发育分析表明了伊豆卡蚓的分类地位以及它与[某分类群]中其他物种的关系，它与[物种1]和[物种2]关系更近（自展值 = 100）。通过比较，伊豆卡蚓和[某分类群]中其他七个物种的基因排列是相同的，并且它们在系统发育树中也以较高的支持率聚类在一起，这表明了[某分类群]中基因排列和系统发育分析之间的保守性。总之，伊豆卡蚓的完整线粒体基因组可以为[某分类群]的进一步分子和进化分析提供支持数据。
