Taxonomic classification of three mitten crabs (Eriocheir sinensis, E. hepuensis, and E. japonica) has long been controversial. In this study, the complete mitogenomes of the three crabs were reported. The three mitogenomes were conserved in the organization of genes with 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region. Nucleotide variations among the crabs were identified in both coding and non-coding regions. In addition, variable numbers of tandem repeats in control region were identified in the mitten crabs. The mitogenome sequences provide a valuable resource to elucidate taxonomic relationship and evolutionary history of the three mitten crabs.
中华绒螯蟹、合浦绒螯蟹和日本绒螯蟹这三种绒螯蟹的分类一直存在争议。在本研究中，报道了这三种蟹的完整线粒体基因组。这三个线粒体基因组在基因组织上具有保守性，包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和1个控制区。在编码区和非编码区均鉴定出了蟹之间的核苷酸变异。此外，在绒螯蟹的控制区还鉴定出了可变数量的串联重复序列。线粒体基因组序列为阐明这三种绒螯蟹的分类关系和进化历史提供了宝贵资源。
