The soft-shell clam (Jay, 1857) is a commercially important fishery resource. In this study, we identified the complete mitochondrial genome of and performed a phylogenetic analysis to explore its genetic relationship with . The genome is 21,396 bp in length and contains 13 protein-coding genes (PCGs), 23 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and 5 D-Loop control regions. The gene was annotated in Myidae for the first time. Notably, the genome contains an additional , consistent with . The length of the gene is 1,947 bp, which is 513 bp longer than that in . Its base composition is 29.14% A, 37.26% T, 10.89% C, and 22.71% G. Phylogenetic analysis based on 12 PCGs and 2 rRNAs indicates that and form a sister group. In this study, the identification and phylogenetic analysis of the complete mitochondrial genome of provide significant information for future taxonomic and evolutionary research of the genus .
软壳蛤（杰伊，1857年）是一种具有重要商业价值的渔业资源。在本研究中，我们鉴定了[物种名称未给出]的完整线粒体基因组，并进行了系统发育分析，以探索其与[物种名称未给出]的遗传关系。该基因组长度为21,396 bp，包含13个蛋白质编码基因（PCGs）、23个转运RNA基因（tRNAs）、2个核糖体RNA基因（rRNAs）和5个D环控制区。[基因名称未给出]基因首次在贻贝科中得到注释。值得注意的是，该基因组包含一个额外的[内容未明确]，与[相关内容未明确]一致。[基因名称未给出]基因的长度为1,947 bp，比[对比对象未明确]中的长513 bp。其碱基组成为29.14% A、37.26% T、10.89% C和22.71% G。基于12个PCGs和2个rRNAs的系统发育分析表明，[物种名称未给出]和[物种名称未给出]形成一个姐妹群。在本研究中，[物种名称未给出]完整线粒体基因组的鉴定和系统发育分析为该属未来的分类学和进化研究提供了重要信息。
