In this study, the complete mitochondrial genome (mitogenome) of prickly redfish (Jaeger, 1833) was determined and characterized from the South China Sea using next-generation sequencing. Our results showed that the length of the whole mitogenome in prickly redfish was 15,858 bp and the mitogenome was consist of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. Furthermore, the nucleotide composition was significantly biased (composition of A, G, T, and C was 28.20%, 22.64%, 33.53%, and 15.63%, respectively) with AT contents of 61.73%. All the PCGs shared a standard initiation codon ATG or GTG. and genes terminated with an incomplete stop codon T, while others ended with TAA or TAG. Our phylogenetic analysis showed that was clustered with the species of genus and formed sister branches with species of other genera within the family Stichopodidae clade.
在本研究中，利用二代测序技术测定并分析了采自中国南海的棘红鱼（Jaeger，1833）的完整线粒体基因组（线粒体基因组）。我们的结果表明，棘红鱼的线粒体基因组全长15,858 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。此外，核苷酸组成存在显著偏差（A、G、T和C的组成分别为28.20%、22.64%、33.53%和15.63%），AT含量为61.73%。所有的PCGs都共享标准起始密码子ATG或GTG， 基因以不完全终止密码子T结束，而其他基因以TAA或TAG结束。我们的系统发育分析表明， 与 属的物种聚类，并与刺参科分支内其他属的物种形成姐妹分支。 （原文中存在部分未明确表述的内容，已尽量按照正确逻辑翻译）
