Mapping of changes in edited sites of five mitochondrial genes. Mapping of edited sites of five mitochondrial genes (atp1, cob, nad5, ccmB, and mtt2) on one of the two most parsimonious trees recovered from the combined analysis of all genes (Acorus was removed from the figure to save space). Branch lengths reflect the number of changes. For each gene, losses of edited sites are indicated above the branch where the change occurred. Gains of edited sites are indicated in a box below the branch where the change was optimized. Colors represent different genes, according to the box at the right. Family names are indicated next to the taxon name, with the following abbreviations: ALI = Alismataceae, LIM = Limnocharitaceae, APO = Aponogetaceae, CYM = Cymodoceae, POS = Posidoniaceae, RUP = Ruppiaceae, ZOS = Zosteraceae, POT = Potamogetaceae, JUN = Juncaginaceae, SCH = Scheuchzeriaceae, and HYD = Hydrocharitaceae.
