The is a commercially valuable scallop known for its long-distance swimming abilities. Despite its economic importance, genetic and genomic research on this species is limited. This study presents the first complete mitochondrial genome of . . The mitochondrial genome is 19,475 bp long and encompasses 13 protein-coding genes, three ribosomal RNA genes, and 23 transfer RNA genes. Two distinct phylogenetic analyses were used to explore the phylogenetic position of the . within the family Pectinidae. Based on one mitochondrial phylogenetic analysis by selecting 15 Pectinidae species and additional outgroup taxa and one single gene phylogenetic analysis by 16S rRNA, two phylogenetic trees were constructed to provide clearer insights into the evolutionary placement of . within the family Pectinidae. Our analysis reveals that is a basal lineage to the Pectininae clade, distinct from its previously assigned tribe, Amusiini. This study offers critical insights into the genetic makeup and evolutionary history of . , enhancing our knowledge of this economically vital species.
太平洋潜泥蛤是一种具有远距离游泳能力的商业价值极高的扇贝。尽管它具有经济重要性，但对该物种的遗传和基因组研究是有限的。本研究介绍了太平洋潜泥蛤的首个完整线粒体基因组。线粒体基因组长 19475bp，包含 13 个蛋白质编码基因、3 个核糖体 RNA 基因和 23 个转移 RNA 基因。两种不同的系统发育分析被用来探索太平洋潜泥蛤在扇贝科内的系统发育位置。基于对 15 种扇贝科物种和其他外群分类单元的线粒体系统发育分析和对 16S rRNA 的 16 个基因系统发育分析，构建了两棵系统发育树，以更清楚地了解太平洋潜泥蛤在扇贝科内的进化位置。我们的分析表明，太平洋潜泥蛤是扇贝亚科分支的一个基础谱系，与它以前所属的 Amusiini 部落不同。这项研究为太平洋潜泥蛤的遗传组成和进化历史提供了关键的见解，增强了我们对这个具有经济重要性的物种的认识。
