In this study, the complete mitochondrial genome of was determined and annotated for the first time. The 15,591 bp circular genome has a base composition of 24.3% A, 38.6% T, 12.5% C, and 24.5% G, demonstrating a bias of higher AT content (63.0%) than GC content (27.0%). The mitochondrial genome contains 12 protein-coding genes (PCGs), 20 transfer RNA genes (tRNA), 2 ribosomal RNA genes ( and ), and one control region. All genes of were encoded on the heavy strand, except trnT(ugu) gene. The whole mitochondrial genome of and 21 mitogenomes of other Mytilidae species were used for phylogenetic analysis. The result indicated the newly sequenced species had the closest relationship with (MK721547) and was clustered within the clade of genus .
在本研究中，首次测定并注释了[物种名称]的完整线粒体基因组。这个15591bp的环状基因组碱基组成为：A占24.3%，T占38.6%，C占12.5%，G占24.5%，显示出AT含量（63.0%）高于GC含量（27.0%）的偏向性。线粒体基因组包含12个蛋白质编码基因（PCGs）、20个转运RNA基因（tRNA）、2个核糖体RNA基因（[基因名称1]和[基因名称2]）以及一个控制区。除trnT(ugu)基因外，[物种名称]的所有基因均在重链上编码。利用[物种名称]的整个线粒体基因组和其他贻贝科物种的21个线粒体基因组进行系统发育分析。结果表明，新测序的物种与[参考物种名称]（MK721547）关系最密切，并聚类在[属名]属的分支内。
