Knowledge of animal mitochondrial genomes is very important to understand their molecular evolution as well as for phylogenetic and population genetic studies. The Lepidoptera encompasses more than 160,000 described species and is one of the largest insect orders. To date only nine lepidopteran mitochondrial DNAs have been fully and two others partly sequenced. Furthermore the taxon sampling is very scant. Thus advance of lepidopteran mitogenomics deeply requires new genomes derived from a broad taxon sampling. In present work we describe the mitochondrial genome of the moth Ochrogaster lunifer.
The mitochondrial genome of O. lunifer is a circular molecule 15593 bp long. It includes the entire set of 37 genes usually present in animal mitochondrial genomes. It contains also 7 intergenic spacers. The gene order of the newly sequenced genome is that typical for Lepidoptera and differs from the insect ancestral type for the placement of trnM. The 77.84% A+T content of its α strand is the lowest among known lepidopteran genomes. The mitochondrial genome of O. lunifer exhibits one of the most marked C-skew among available insect Pterygota genomes. The protein-coding genes have typical mitochondrial start codons except for cox1 that present an unusual CGA. The O. lunifer genome exhibits the less biased synonymous codon usage among lepidopterans. Comparative genomics analysis study identified atp6, cox1, cox2 as cox3, cob, nad1, nad2, nad4, and nad5 as potential markers for population genetics/phylogenetics studies. A peculiar feature of O. lunifer mitochondrial genome it that the intergenic spacers are mostly made by repetitive sequences.

动物线粒体基因组的知识是非常重要的，了解它们的分子进化以及系统发育和种群遗传研究.鳞翅目包括超过160,000种描述，是最大的昆虫订单之一。迄今为止，只有9鳞翅目线粒体DNA已充分，另外两名部分测序。此外，该分类单元抽样是非常缺乏。因此，对鳞翅目mitogenomics深入推进，需要新的基因组从广泛的类群抽样所得。在目前的工作中，我们描述了蛾草原田鼠lunifer线粒体基因组。
对澳lunifer线粒体基因组是一个圆形的分子15593 bp的长。它包括37个基因动物线粒体基因组通常在目前整个集合。它也包含7间区。 该基因组测序的新基因顺序是，鳞翅目昆虫的典型，从为trnM安置祖先类型不同。在A + T的77.84％的α链的内容是属于已知鳞翅目昆虫基因组最低。澳lunifer的展品中最显着的C - 1线粒体基因组之间的歪斜可用翅亚纲昆虫基因组。该蛋白编码基因具有典型的线粒体cox1除外启动密码子，在目前一个不寻常的海巡署。本澳lunifer基因组展品中较偏向鳞翅目同义密码子使用。比较基因组学分析研究确定为cox3 atp6的，cox1，COX2的，穗轴，nad1，nad2，nad4和nad5为群体遗传学/系统学研究的潜在标志物。澳lunifer特有的功能，线粒体基因组认为间隔区大多是由重复序列。

嚯~~太复杂了 我看得头都晕了 有些单词我从来没见过 是不是专业术语哦 你的这篇论文让我觉得我学的太少了
不足之处，见谅哈 但愿能帮到你
