Maize and teosinte mitogenomes evolutionary tree. Parsimonious phylogenetic tree (built with MGR) using GSSs. Branch length is proportional to the number of rearrangement events (inversion, duplications, deletions). An Ancestral sequence is given for each node (A1 to A5). Rearrangement events are given on each branch: I = inversion, TD = tandem duplication, L = synteny anchor loss, TDPL = tandem duplication with partial loss. Numbers between vertical lines correspond to blocks affected by rearrangements.
