Adult PIF overexpressors exhibit constitutive SAS under normal high R:FR conditions and attenuated SAS responses under simulated shade conditions. a Comparison of the rosette leaf number, leaf blade area, and petiole length of the first and second leaf between PIF overexpressors, pifq, and WT plants grown under normal high R:FR (WL) or simulated shade (EOD-FR) conditions. Eight-day-old seedlings were moved into the soil and grown under WL with or without EOD-FR treatment for 4 weeks. Bar = 2 cm. b Quantification of the rosette leaf number, leaf blade area, and petiole length of PIF ovexpressors, pifq, and WT under WL or EOD-FR conditions. Values shown are mean ± SD (n = 12). Different letters indicate significant differences by two-way ANOVA
