Fig. 1. Schematic diagram of FCA function in sustaining POR abundance at warm temperatures. (A) FCA induces POR transcription. At warm temperatures, FCA binds to the promoter regions of POR genes to promote their transcription through histone acetylation. (B) FCA inhibits POR degradation. POR proteins are highly unstable at warm temperatures. FCA stabilizes PORs possibly by suppressing plastid proteases. (C) POR enzymes shifts the chlorophyll-ROS balance toward autotrophic development. POR abundance is maintained by FCA at warm temperatures, which leads to light-induced chlorophyll biosynthesis, while suppressing ROS production.
