The mitochondrial genome from the stonefly: Claassenia sp. (Plecoptera: Perlidae).

ABSTRACT: Claasseniini is the apparent sister group to all the other groups of Perlidae, and the small tribe Claasseniini has only one genus includes 12 species in the world. Only five mitochondrial genomes in the Perlinae have previously been reported. In this study, we sequenced the mitochondrial genome of Claassenia sp. Wu in genus Claassenia for the first time. The total length of the mitochondrial genome is 15,774?bp, and the DNA base composition is 34.0% A, 27.4% T, 25.6% C and 13.0% G. The whole genome contains 37 genes and one control region, which is similar to other published stoneflies. All PCG started with ATN except CCG for COI gene, TTG for ND1 gene, GTG for ND4 and ND5 genes. The termination codon of 11 PCGs used the normal complete codon TAA or TAG, and the COII and ND5 genes were terminated by a single T. All tRNAs except tRNA^Ser(AGN) fold into a classic clover structure. The phylogenetic tree by Maximum likelihood (ML) and Bayesian (BI) methods supported that Claassenia sp. was the basal taxa of the Perlidae clade. This study provides new data for further mitochondrial genome study on the Perlidae.

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).
