The C-terminal module of PHYB regulates a subset of PIF-dependent genes. a Venn diagrams showing that 72.3% of BCY-induced and PIF-dependent genes are PIF-repressed and 93.4% of BCY-repressed and PIF-dependent genes are PIF-induced. b GO term enrichment analysis showing the top five enriched biological processes with the lowest p-value for the BCY-induced, PIF-repressed genes (left panel) and the BCY-repressed, PIF-induced genes (right panel). c qRT-PCR results showing the expression levels of four representative BCY-induced, PIF-repressed photosynthetic genes in 4-day-old Col-0, phyB-9, pifq, YHB, BCY-2, BCY18, and BCY18N seedlings grown in the dark. d qRT-PCR results showing the expression levels of four representative PIF-induced growth-relevant genes in 4-day-old Col-0, phyB-9, pifq, YHB, BCY-2, BCY18, and BCY18N seedlings grown in the dark, indicating that this group of growth-related genes are not dependent on BCY
