Most of the rearranged genes were located in the ancestral region of trnl-trnQ-trnM-nad2-trn W-trnC-trn Y- coxl-trnL2. The other rearranged genes are trnN and trnS1 located in the tRNA cluster trnA- trnR-trnN-trnSl-trnE-trnF and trnS2 located between cob and nadl. Remote inversion is dominant rearrangement event in G. parvicollarium mitochondrial genome, involving two protein-coding and 8 tRNA genes. Compared with the other mitochondrial genome reported in the same genus of Gasteruption, the inverted trnN was translocated to the tRNA cluster between cox1 and nad2 in G. parvicollarium. This is the first report of mitochondrial gene rearrangement occurred within genus of Hymenoptera. Our study points to a recently occurred gene rearrangement event in the Gasteruption species.展开更多
