Abstract

Here we present the complete mitochondrial genome of Tetraclita squamosa squamosa, which is 15,191 bp in length with 67.20% AT content. It contains 13 protein-coding genes, 2 ribosomal-RNA genes and 22 transfer-RNA genes. All PCGs except nad4l in T. squamosa squamosa start with ATN, and terminated with a complete stop codon, except nad3. Phylogenetic analysis based on mitochondrial PCGs shows that T. squamosa squamosa is clustered with T. serrata into a branch (BP = 100). Our result is consistent with previous reports that genus Tetraclita and family Tetraclitidae are not monophyletic. This study contributes to further phylogenetic analysis within Cirripedia.

摘要

在这里，我们介绍了Tetraclita squamosa squamosa的完整线粒体基因组，其长度为15,191 bp，AT含量为67.20％。它包含13个蛋白质编码基因，2个核糖体RNA基因和22个转移RNA基因。T. squamosa squamosa中除nad4l以外的所有PCG均以ATN开头，并以完整的终止密码子终止，nad3除外。基于线粒体PCG的系统发育分析表明，鳞茎 鳞茎与锯齿鳞茎成簇成一个分支（BP = 100）。我们的结果与之前的报道一致认为属Tetraclita和家庭Tetraclitidae不是单一的。这项研究有助于在Cirripedia中进行进一步的系统发育分析。
