Abstract

Here, we present the complete mitochondrial genome of . The genome is 15,771 bp in length with a 68.07% AT content. It contains 13 protein-coding genes, two rRNAs genes, and 22 tRNAs. Both rRNAs are encoded on the light strand. Besides seven tRNAs are encoded on the light strand (trnY, trnQ, trnV, trnL1, trnP, trnH, and trnF), and four PCG (nad1, nad4l, nad4, and nad5) are encoded on the light strand, whereas the other nine PCGs are located on the heavy strand. Phylogenetic analysis based on mitochondrial PCGs shows two distinct groups for Stomatopoda and Decapoda. is found clustered with into a branch (BP = 100), and they grouped with other species with high support (BP = 99) in the family Squillidae. Our results shall provide a better understanding in the evolutionary histories of the stomatopods.

摘要

在此,我们展示了……的完整线粒体基因组。该基因组长度为15771 bp,AT含量为68.07%。它包含13个蛋白质编码基因、两个rRNA基因和22个tRNA。两个rRNA均由轻链编码。此外,七个tRNA由轻链编码(trnY、trnQ、trnV、trnL1、trnP、trnH和trnF),四个蛋白质编码基因(nad1、nad4l、nad4和nad5)由轻链编码,而其他九个蛋白质编码基因位于重链上。基于线粒体蛋白质编码基因的系统发育分析显示,口足目和十足目分为两个不同的类群。……被发现与……聚为一个分支(BP = 100),并且它们在虾蛄科中与其他物种聚在一起,支持率很高(BP = 99)。我们的结果将有助于更好地理解口足类动物的进化历史。
