—Phylogenomic evidence for a whole-genome duplication event in the ancestor of all palms. The color bar represents the number of unique gene duplications placed at each node, with at least 80% bootstrap support. The tree has representatives of 4/5 palm subfamilies (Calamoideae = Mauritia; Nypoideae = Nypa; Coryphoideae = Phoenix, Serenoa; Arecoideae = Chamaedorea, Cocos, Elaeis, Howea).
