Seedling phenotypes of rsf1 mutants. A, Wild-type, rsf1, and phyA-211 seedlings were grown for 4 d in continuous FR light 0.8 or 2 μmol m⁻² s⁻¹, representative seedlings were photographed. B, Picture of a representative wild-type and rsf1 seedlings grown for 4 d in continuous FR light on Suc-containing plates. Note that the mutant still accumulates anthocyanin. C, Quantification of anthocyanin accumulation in phyA-211, rsf1, and wild-type seedlings. Seedlings were grown on Suc-containing plates under 8 μmol m⁻² s⁻¹ FR light for 4 d. The experiment was done in triplicate with 10 seedlings for each measurement (mean ± 2× se).
