Phenotypes of plants overexpressing genes of the two clades. A and B, Seedlings (A) and plants (B) overexpressing the MYB28-like clade genes under the control of the early AS1 promoter. C, Overexpression of ATR1-like clade members under the control of the relatively late 650 promoter. D and E, Wild-type (WT) plant (D) and wild-type inflorescence (E). F and G, Plant overexpressing ATR1/MYB34 driven by the AS1 promoter (F) and its inflorescence (G). H and I, Plant overexpressing MYB51 driven by the AS1 promoter (H) and its inflorescence (I). J to L, Expression of a DR5:GUS marker for free auxin production in the wild type (J) and in 650≫ATR1 (K) and 650≫MYB51 (L) backgrounds. M and N, Expression pattern of YFP and GUS reporter genes driven by the AS1 promoter (M) and driven by the 650 promoter (N).
