In this study, the complete mitochondrial genome (mitogenome) of (Gray, 1846) (Lepidoptera: Nymphalidae) was first reported with 15,298 bp in size, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes ( and ), and one control region. The nucleotide composition of the entire mitogenome is highly A + T biased (81.5%). The gene content and arrangement of the newly sequenced mitogenome are identical to those of the other available mitogenomes of Nymphalidae. All PCGs start with the conventional ATN codons, except for initiating with atypical CGA(R). Nine PCGs (, , , , , , , , and ) utilize a typical stop codon TAA, whereas the remaining PCGs (, , , and ) end with an incomplete stop codon T-. Phylogenetic analysis revealed that is closely related to within Pseudergolinae, which further forms the sister group to the grouping of (Nymphalinae + (Cyrestinae + (Biblidinae + Apaturinae))). The complete mitogenome of will provide useful genetic information for improving the taxonomic system and phylogenetics of Nymphalidae.
在本研究中,首次报道了黛眼蝶(Gray,1846)(鳞翅目:蛱蝶科)的完整线粒体基因组(线粒体基因组),大小为15,298 bp,包含13个蛋白质编码基因(PCGs)、22个tRNA基因、两个rRNA基因( 和 )以及一个控制区。整个线粒体基因组的核苷酸组成高度偏向A + T(81.5%)。新测序的线粒体基因组的基因内容和排列与蛱蝶科其他可用的线粒体基因组相同。除 以非典型的CGA(R)起始外,所有PCGs均以常规的ATN密码子起始。九个PCGs( 、 、 、 、 、 、 、 和 )使用典型的终止密码子TAA,而其余的PCGs( 、 、 、 和 )以不完整的终止密码子T-结尾。系统发育分析表明,黛眼蝶在伪眼蝶亚科内与 密切相关,后者进一步形成了(蛱蝶亚科 + (釉蛱蝶亚科 + (喙蝶亚科 + 钩翅蛱蝶亚科)))分组的姐妹群。黛眼蝶的完整线粒体基因组将为完善蛱蝶科的分类系统和系统发育学提供有用的遗传信息。
