Fig. 2: CRG expansion as a result of polyploidization events during the evolution of different plant groups.

A blue four-pointed star represents tetraploidy events, including β, α, τ, σ, ρ and some θ events. A red six-pointed star represents hexaploidy events, including γ and some θ events. A yellow circle represents decaploidy events, which occurred only in Malvaceae. The number on the branch represents the number of CRGs included in each species related to each duplication event. Venn diagrams show the numbers of common and unique CRGs in each examined species
