Phylogeny of LBD proteins from Class IB in 18 species. This phylogeny was reconstructed using Class IB LBD proteins identified in Figure 1 and according to the same method described in Figure 1 legend. “*” means functionally characterized LBD protein in Table 2 (Gene ID is in brackets for LBD proteins of 18 species, species name is in square brackets for LBD proteins of other species). LBD proteins of eudicots, monocots, and other plant species are marked in red, blue and black, respectively. Branch color corresponds to that in Figure 1.
