Phytochromes directly associate with chromatin through TFs, coregulators, or both and control gene expression. (a) phyB is enriched to temperature-regulated genes at lower temperature possibly through interaction with PIFs, other TFs, or both. (b) phyA and FHY1 together associate with TFs to regulate their specific binding to different cis elements. (c) phyA and (d) FHY1 interact with TFs to regulate their specific binding to different cis elements independently. (c) phyA and (f) FHY1 interact with TFs and regulate their specific binding with the aid of unknown factors. Different DNA colors indicate different cis elements. X and Y indicate unknown factors that are involved in specific associations. Abbreviations: phy, phytochrome; TF, transcription factor.
