Fig. 4

Karyotype projection of 21 core eudicot species. The topology is the same as in Fig. 1 and the branch length represent the divergence time (see detail in Additional file 1: Fig. S9). Different background colors represent different lineages corresponding to Fig. 1: light purple represents Caryophyllales, light blue represents asterids, light pink represents rosid clades I and III, and light yellow represent rosid clade II. Polyploidization events are indicated by red dots (duplication) and blue stars (triplication). Shared fusion events are marked below the corresponding lineages
