Repartition of Backbone DNA sequences and Genome Structure Sequences (GSSs) Sequences on each mitogenome. For each mitogenome, a pair of box sequences is represented : the backbone DNA sequence (BB) and the genome structure sequence before paralog identification and synteny anchor collapsing (GSS bpisac). Each box is either a Backbone DNA fragment for BB, or a synteny anchor for GSS bpisac. Boxes with the same number are homologous synteny anchors. The numbering of boxes was chosen according to Zea mays ssp. mays NA. Thus on BB and GSS bpisac, a box is drawn on the left side if it has the same orientation than its homolog in NA, on the right side otherwise. For each mitogenome, thick lines represent duplicated regions.
