Abstract excerpt
Phytochrome B (phyB) inhibits the function of phytochrome-interacting factors (PIFs) by inducing their degradation and sequestration, but the relative physiological importance of these two phyB activities is unclear. In an analysis of published Arabidopsis thaliana phyB mutations, we identified a point mutation in the N-terminal half of phyB (phyBG111D) that abolishes its PIF sequestration activity without...
