线粒体基因组可以提供关于其宿主生物体的生物学和进化历史的有价值的信息。在这里，我们提出并描述了完整的编码区的107线粒体基因组（有丝分裂基因组）的蝉（昆虫纲：半翅目：Auchalphrhyncha：蝉总科），代表31属，61种，和83个种群。我们发现，所有的hmmitogenomes保留的组织和基因内容被认为是祖先在昆虫中，与一些变异hmmitogenomes之间的基因nad2和cox1，编码3个tRNA之间的区域的长度。系统发育分析，使用这些有丝分裂基因组概括了最近的5个基因的分类蝉的家庭和亚科，但也确定了一个物种，福尔斯以外的既定的分类框架。虽然蛋白质编码基因是在强大的纯化选择，相对进化速率的测试显示进化速率跨类群的显着变化，突出了蝉线粒体基因组进化的动态性质。这些数据将为今后研究蝉总科的系统学、生态学和进化提供有用的参考。
Mitochondrial genomes can provide valuable information on the biology and evolutionary histories of their host organisms. Here, we present and characterize the complete coding regions of 107 mitochondrial genomes (mitogenomes) of cicadas (Insecta: Hemiptera: Auchenorrhyncha: Cicadoidea), representing 31 genera, 61 species, and 83 populations. We show that all cicada mitogenomes retain the organization and gene contents thought to be ancestral in insects, with some variability among cicada clades in the length of a region between the genes nad2 and cox1, which encodes 3 tRNAs. Phylogenetic analyses using these mitogenomes recapitulate a recent 5-gene classification of cicadas into families and subfamilies, but also identify a species that falls outside of the established taxonomic framework. While protein-coding genes are under strong purifying selection, tests of relative evolutionary rates reveal significant variation in evolutionary rates across taxa, highlighting the dynamic nature of mitochondrial genome evolution in cicadas. These data will serve as a useful reference for future research into the systematics, ecology, and evolution of the superfamily Cicadoidea.
