Characterization of the complete mitochondrial genome of the ecotoxicity indicator insect Aiolopus thalassinus (Orthoptera; Acrididae; Oedipodinae)

摘要

The grasshopper Aiolopus thalassinus has long been used as an ecotoxicity indicator species of heavy metal pollution. The rapid molecular identification and genetic resource determination of this species would be of great helpful for the application in environmental monitoring. Mitochondrial DNA sequences are the widely applied molecular markers in insect taxonomic identification. In this study, we reported the complete mitochondrial genome of A. thalassinus. The whole genome was 15,753 bp in size and encoded 37 typical mitochondrial genes. The nucleotide composition was asymmetric, with an obvious bias towards A and T (75.3% combined). The typical ATN start codons were exhibited in the initiation of all protein-coding genes (PCGs). The typical TAA/TAG codons or the incomplete T(aa) codon were the terminal codons. The control region was determined by its remarkably high A+T content of 83.3%. This mitochondrial genome data for A. thalassinus will provide a useful resource for environmental monitoring.
