The characterization of the mitochondrial genome of Calineuria stigmatica (Plecoptera: Perlidae)

Abstract

The nearly complete sequence of the mitochondrial DNA of Calineuria stigmatica has been completed and annotated in this study. The circular genome is 15,070 bp in length with an A + T content of 61.8% and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The control region can only be assembled partially. All PCGs use normal start codon ATN, while COI, ND1, and ND5 use CCG, TTG, and GTG as start codon, respectively. Meanwhile, 10 PCGs use the typical termination codons TAN, except COII, ND4, ND5, which stopped with the incomplete terminaton signal T––. Based on 13 PCGs and two rRNAs using the Bayesian (BI) method supported that C. stigmatica was closely grouped with four other Acroneuriinae species. Our results provide basic data for further study of phylogeny in Plecoptera.
