Recapitulating ilr3-1 mutant phenotypes by overexpressing ilr3-1 in wild type. Col-0 (Wt), ilr3-1, ilr3-2, and two independent lines each for Wt (35S–ILR3) and Wt (35S–ilr3-1) were grown on unsupplemented medium or medium containing the indicated concentrations of IAA–Leu (A and B), IAA–Phe (C and D), MnCl₂ (E and F), or IAA (G). Medium in A–D and G contained 0.5% sucrose; that in E and F lacked sucrose. Root lengths were measured after 8 days of growth in yellow-filtered light (n ≥ 10). Error bars represent standard errors of the means.
