Complete mitochondrial genome of Oxya chinensis (Orthoptera, Acridoidea)

The complete sequence of Oxya chinensis (O. chinensis) mitochondrial genome is reported here. It is 15,443 bp in length and contains 75.9% A+T. The protein‐coding genes have a similar A+T content (75.2%). The initiation codon of the cytochrome oxidase subunit I gene in the mitochondrial genome of O. chinensis appears to be ATC, instead of the tetranucleotides that have been reported in Locusta migratoria (L. migratoria) mitochondrial genome. The sizes of the large and small ribosomal RNA genes are 1319 and 850 bp, respectively. The transfer RNA genes have been modeled and showed strong resemblance to the dipteran transfer RNAs, and all anticodons are identical to those of dipteran. The A+T‐rich region is 562 bp, shorter than that of other known Orthoptera insects. The six conserved domains were identified within the A+T‐rich region by comparing its sequence with those of other grasshoppers. The result of phylogenetic analysis based on the dataset containing 12 concatenated protein sequences confirms the close relationship of O. chinensis with L. migratoria.
