Surgeonfishes of the family Acanthuridae are primarily large-bodied herbivores that provide critical ecosystem services to coral reefs. Five out of the six genera that comprise the family have had mitochondrial genomes sequenced, with the exception of the genus . Here, for the first time, we assemble and annotate the mitochondrial genomes of two sawtail surgeonfishes. The circular genomes of and are 16,552 bp and 16,531 bp in length, respectively, and contain 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. Gene arrangement and codon usage were similar to reported mitochondrial genomes of other surgeonfish genera, and a phylogenetic analysis of protein-coding genes recovers a topology for Acanthuridae that is consistent with nuclear analyses.
刺尾鱼科的刺尾鱼主要是大型草食性鱼类,它们为珊瑚礁提供重要的生态系统服务。构成该科的六个属中有五个属的线粒体基因组已被测序, 属除外。在这里,我们首次组装并注释了两种锯尾刺尾鱼的线粒体基因组。 和 的环状基因组长度分别为16,552 bp和16,531 bp,包含13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和一个控制区。基因排列和密码子使用情况与其他刺尾鱼属已报道的线粒体基因组相似,对蛋白质编码基因的系统发育分析得出了一个与核分析一致的刺尾鱼科拓扑结构。
