The genus is one of most abundant and widespread marine bivalves. To date, its intra-generic phylogeny remains disputed and mitogenome information is therefore much needed. Here, we first report the complete circular mitogenome of sp. J that is distributed in the coast of Asia Pacific. The total length of this mitochondrial genome is 21,233 base pairs. It consists of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a major noncoding region (MNR). Phylogenetic analysis of COI from 25 species (Hiatellidae) revealed that the sp. J was closely related to Asian in the family Hiatellidae. This mitogenome provides new molecular data for the further taxonomic and phylogenetic studies of the genus of marine bivalves.
该属是最丰富且分布广泛的海洋双壳贝类之一。迄今为止，其属内系统发育仍存在争议，因此非常需要线粒体基因组信息。在此，我们首次报道了分布于亚太海岸的J种[具体物种名未给出，用“J种”暂代]的完整环状线粒体基因组。该线粒体基因组全长21233个碱基对。它由13个蛋白质编码基因、22个转运RNA、2个核糖体RNA和一个主要非编码区（MNR）组成。对25个物种（海笋科）的细胞色素氧化酶亚基I（COI）进行系统发育分析表明，J种[具体物种名未给出，用“J种”暂代]与海笋科的亚洲[具体物种名未给出，用“亚洲”暂代]关系密切。这个[具体物种名未给出，用“这个”暂代]线粒体基因组为海洋双壳贝类该属的进一步分类和系统发育研究提供了新的分子数据。
