Putative gene rearrangement events in Cotesia vestalis mitochondrial genome. Four regions underwent gene rearrangements. Rearranged genes are shown in gray. The region from cox3 to cob experienced protein-coding gene rearrangements, and three types of rearrangement events might happen: large-scale inversion, tRNA rearrangement and small region rearrangement. The intermediate statuses are used to show different types of gene rearrangement events, but not the rearrangement process.
