A phyB-PIF1-SPA1 kinase regulatory complex promotes photomorphogenesis in Arabidopsis

SPA proteins repress plant photomorphogenesis by promoting the E3 ligase activity of COP1. Here the authors show that SPAs also act as serine/threonine kinase and are required for phyB-mediated light-dependent phosphorylation and degradation of the PIF1 transcription factor.
