Predicted evolution from A5 to NA and Zea mays ssp. Parviglumis. Example of an evolutionary scenario from A5 to Zea mays ssp. mays NA and Zea mays ssp. parviglumis. A5 (the ancestral sequence computed by MGR) and intermediate mitogenomes after each rearrangement event are shown. Evolution of A5 mitogenome through inversions, tandem duplications (respectively yellow and blue in the middle circle) and synteny anchor loss (black in the internal circle) leads to NA (with 2 rearrangements) and Zea mays ssp. parviglumis (with 7 rearrangements). Duplicated synteny anchors are in red (outside circle). On each branch, the rearrangement event is indicated (I = Inversion, TDPL = Tandem Duplication with Partial Loss). For NA, the TDPL is indicated in two steps: a duplicated event followed by a deletion event.
