The hard clam () is an important economic and ecological bivalve. In this study, the mitochondrial genome was sequenced. The sequenced genome size was 18,360 bp. The nucleotide composition was asymmetric with a AT bias. Mitogenome contained 13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes. Of 13 PCGs, 3 genes (, , and ) had incomplete stop codons. Furthermore, phylogenetic analysis using 12 PCGs (except ) figured out that was closely related to genus . The complete mitogenome of provides essential information for further phylogenetic and evolutionary analysis in Veneridae.
硬壳蛤（）是一种重要的经济和生态双壳贝类。在本研究中，对其线粒体基因组进行了测序。测序后的基因组大小为18360 bp。核苷酸组成不对称，具有AT偏向性。线粒体基因组包含13个蛋白质编码基因（PCGs）、2个rRNA基因和22个tRNA基因。在13个PCGs中，有3个基因（、和）具有不完整的终止密码子。此外，使用12个PCGs（除外）进行的系统发育分析表明，与属密切相关。硬壳蛤的完整线粒体基因组为帘蛤科进一步的系统发育和进化分析提供了重要信息。
