本文报道了中华稻蝗线粒体基因组的全序列。该基因全长15,443个碱基，A+T含量为75.9%，编码蛋白质的基因A+T含量相似(75.2%)。中华稻蝗线粒体基因组中细胞色素氧化酶I亚基基因的起始密码子可能是ATC，而不是蝗虫线粒体基因组中已报道的四核苷酸。大的和小的核糖体RNA基因的大小分别为1319和850个核苷酸。转移RNA基因已被模拟，并显示出与双翅目昆虫转移RNA的高度相似之处，所有反密码子都与双翅目昆虫的完全相同。A+T富集区全长562个碱基对，比已知的直翅目昆虫短。通过与其他蝗虫的序列比较，确定了A+T富集区中的6个保守结构域。基于包含12个串联蛋白序列的数据集的系统发育分析的结果证实了中国对虾与迁徙亚种的亲缘关系。
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.
