(Say, 1822) is a species of the bivalve family Mactridae and represents a promising model species for molluscan research. In this study, the complete mitochondrial genome (mitogenome) of was sequenced and assembled for the first time. The 21,668 bp mitogenome contained 13 protein-coding genes, 2 rRNAs, 22 tRNA genes, and an AT-rich region. The overall AT content (69.56%) was higher than GC content (30.44%). Phylogenetic analysis supported that belongs to the family Mactridae. The mitochondrial genome of provides a valuable resource for further understanding the phylogeny of the family Mactridae and for functional studies of molluscan mitochondrial genes.
（比如，1822年）是双壳贝类马珂蛤科的一个物种，是软体动物研究中一个很有前景的模式物种。在本研究中，首次对（该物种）的完整线粒体基因组（线粒体基因组）进行了测序和组装。这个21,668 bp的线粒体基因组包含13个蛋白质编码基因、2个核糖体RNA、22个转运RNA基因以及一个富含AT的区域。总体AT含量（69.56%）高于GC含量（30.44%）。系统发育分析支持（该物种）属于马珂蛤科。（该物种的）线粒体基因组为进一步了解马珂蛤科的系统发育以及软体动物线粒体基因的功能研究提供了宝贵资源。
