The complete mitochondrial genome of from South China Sea was first determined in this study, which is 16,596 bp in length. The base composition of the mitogenome is a less biased (A, G, T, and C was 21.5%, 26.3%, 37.0%, and 15.2%, respectively) with A + T contents of 58%. It consists of 24 tRNA genes, two rRNA genes, and 12 protein-coding genes (PCGs). No typical control region was found in non-coding sequence. Interestingly, ATP8 genes was absence same as most shellfish. Nine PCGs use a special start codon TTG, and the other three genes use a normal initiation codon ATN. Except ND6 use a single base G as the stop codon, the others all end with the normal stop codon TAG. The phylogenetic tree showed that was first clustered with , , and , which all belong to Cardiidae.
本研究首次测定了来自中国南海的[物种名称未给出]的完整线粒体基因组,其长度为16,596 bp。该线粒体基因组的碱基组成偏差较小(A、G、T和C分别为21.5%、26.3%、37.0%和15.2%),A+T含量为58%。它由24个tRNA基因、2个rRNA基因和12个蛋白质编码基因(PCGs)组成。在非编码序列中未发现典型的控制区。有趣的是,与大多数贝类一样,ATP8基因缺失。9个PCGs使用特殊的起始密码子TTG,其他3个基因使用正常的起始密码子ATN。除ND6使用单个碱基G作为终止密码子外,其他基因均以正常的终止密码子TAG结尾。系统发育树显示,[物种名称未给出]首先与均属于心蛤科的[其他物种名称未给出]、[其他物种名称未给出]和[其他物种名称未给出]聚类。
