Dataset Information

The mitochondrial genome of the stonefly Togoperla limbata Pictet (Plecoptera: Perlidae).

ABSTRACT: We sequenced the complete mitochondrial genomes of Togoperla limbata which is the unique species distributed in Japan to provide supplementary data for future study in phylogenetic studies of Perlidae. This complete mitogenome of T. limbata is 15,915 bp long, including 37 typical genes and a control region as other stoneflies. Through the data analysis, the A + T content of the whole mitogenome, PCGs, tRNAs, rRNAs, and control region was 63.7%, 61.3%, 68.7%, 66.8%, and 74.8%. Most PCGs used typical start or stop codon except COI, ND5, and ND1 used the exceptional start codon and the COII and ND5 used the single T as the stop codon. Phylogenetic tree was constructed by using Bayesian inference (BI) and maximum-likelihood (ML) analysis based on the sequences of the 13 PCGs and two rRNAs and the result showed that subfamily Perlinae was a monophyletic group and the clade Togoperla and Paragnetina had a closer relationship.

Project description:Of the roughly 400 species of Perlidae in the world, most species are widely distributed in the northern hemisphere, but a few can be found in South Africa and South America. There are only five species in the genus Flavoperla of the family Perlidae in China. To gain a better understanding of the architecture and evolution of mitochondrial genome in Flavoperla, the entire mitochondrial genome (mitogenome) of a Chinese Flavoperla biocellata Chu, 1929 from family Perlidae (Insecta: Plecoptera) was sequenced. The 15,805-bp long mitochondrial genome of F. biocellata contained 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a putative control region (CR). The gene arrangement of F. biocellata was identical with that of other stoneflies and with the fly Drosophila yakuba. Most PCGs of F. biocellata used the standard ATN start codons and complete TAN termination codons. Twenty-one of the 22 tRNA genes exhibited cloverleaf secondary structures, but the dihydrouridine (DHU) arm of trnSer (AGN) was completely reduced. Phylogenetic analyses with both Bayesian inference (BI) and maximum likelihood methods (ML) generated similar topology, both supporting the monophyly of all stonefly families and the infraorder Systellognatha. The phylogenetic analysis based on mitochondrial genomic data from 30 stonefly species recovered a well-supported tree resolving higher-level relationships within Plecoptera. The northern hemisphere suborder Arctoperlaria divided into two groups, Euholognatha and Systellognatha. The southern hemisphere suborder Antarctoperlaria formed two clades: Eustheniidae+Diamphipnoidae and Austroperlidae+ Gripopterygidae; consistent with relationships proposed based on morphology. The final relationships within Plecoptera were recovered as (((Perlidae+(Perlodidae+Chloroperlidae))+(Pteronarcyidae+(Peltoperlidae+Styloperlidae))) +(Taeniopterygidae+(Capniidae+(Nemouridae+Notonemouridae))))+ (Gripopterygoidae+Eusthenioidae).
