本研究获得并描述了斑节对虾（Saron marmoratus）的线粒体全基因组。该线粒体全基因组大小为16330bp，包含13个蛋白质编码基因（PCGs）、2个核糖体RNA基因和22个转运RNA基因。14个基因由轻链编码，另外23个基因由重链编码。重链的A + T含量为67.89%。除了ND4以GAT起始外，大多数蛋白质编码基因以ATN作为起始密码子。11个蛋白质编码基因以完整的终止密码子TAN终止，但2个蛋白质编码基因（ND5和Cytb）具有不完整的终止密码子。系统发育分析表明，藻虾科（Hippolytidae）虾可能被视为多系类群。这些结果有助于理解藻虾科虾的系统发育关系和进化。
The complete mitochondrial genome of shrimpSaron marmoratuswas obtained and characterized in this study. This complete mitochondrial genome is 16,330 bp in size and comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes, and 22 transfer RNA genes. Fourteen genes were encoded by light strand and another 23 genes were encoded by heavy strand. The A + T content of the heavy-strand was 67.89%. Most PCGs had ATN as the start codon except ND4 initiated with GAT. Eleven PCGs terminated with a complete stop codon TAN, but two PCGs (ND5andCytb) had an incomplete stop codon. The phylogenetic analysis suggested that Hippolytidae shrimp may be considered as the polyphyletic taxon. These results are useful for understanding the phylogenetic relationships and evolution of Hippolytidae shrimp.
