Phylogeny for the rosid genomes used as test cases in this study, with known ancient WGDs marked on the branches. Phylogeny of rosid genomes with circles denoting polyploidy events. α, β and ρ: tetraploidies; γ: hexaploidy. The quota displayed in the table are in the form of QX:QY, where QX is the expected multiplication level for the genome on the top of the table, and QY is the expected multiplication level for the genome on the right.
