Fig. 5 — MIR156s act downstream of PIFs in regulating SAS. a The rosette leaf number, leaf blade area, and petiole length of the first and second leaf of WT, PIF5-OE, pifq, MIR156-OE, MIM156, and their higher order mutants grown under WL with or without EOD-FR treatment. Eight-day-old seedling grown on Murashige and Skoog agar medium under WL were transferred into soil and treated with EOD-FR for 4 weeks before phenotypic analysis. Bar = 2 cm. b Quantification of the rosette leaf number, leaf blade area, and petiole length of WT, PIF5-OE, pifq, MIR156-OE, MIM156, and their higher order mutants grown under WL with or without EOD-FR treatment. Values given are mean ± SD (n = 12). Letters indicate significant differences by two-way ANOVA. c Simplified schematic model depicting the signaling pathway of PIFs and MIR156 to modulate shade-avoidance response in adult Arabidopsis plants. Shade (low R:FR ratios) inactivates phyB and induces a rapid accumulation of PIF proteins. These PIFs then directly bind to the promoters of multiple MIR156 genes and repress their expression, which alleviates the inhibitory effect of MIR156s on their target SPL genes. The activated SPL genes then regulate diverse morphological changes associated with shade-avoidance responses via altering distinct sets of further downstream genes. Arrow: activate; Bar: repress
