Dark reversion of the red-light receptor phytochrome B (phyB) converts the receptor to the inactive state. Here, Enderle et al. show that PCH1 and PCHL bind phyB and suppress dark reversion, and that far-red and blue-light induced upregulation of PCH1 and PCHL increases red light sensitivity in Arabidopsis.
