In this study, we first determined and characterised the complete mitochondrial genome of seven-eleven crab from South China Sea. The mitogenome is 15,761 bp long, and consists of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. The nucleotide composition of mitogenome is significantly biased (A, G, T, and C was 35.9%, 9.8%, 35.5%, and 18.9%, respectively) with A + T contents of 71.3%. Three PCGs used an unusual initiation codon, and four PCGs were terminated with an uncomplete or abnormal stop codon. Six microsatellites were identified in mitogenome sequences. Phylogenetic tree showed that formed monophyletic clade with other Heterotremata species.
在本研究中，我们首先测定并表征了来自中国南海的7-11蟹的完整线粒体基因组。该线粒体基因组长度为15,761 bp，由22个tRNA基因、2个rRNA基因、13个蛋白质编码基因（PCGs）和1个控制区组成。线粒体基因组的核苷酸组成存在显著偏差（A、G、T和C分别为35.9%、9.8%、35.5%和18.9%），A+T含量为71.3%。三个PCGs使用了不寻常的起始密码子，四个PCGs以不完整或异常的终止密码子终止。在线粒体基因组序列中鉴定出六个微卫星。系统发育树显示，与其他异孔亚纲物种形成了单系分支。
