Abstract
Phytochrome signaling allows plants to sense and respond to light through gene regulation. Ushijima et al. (2017) demonstrate a role for phytochromes in widespread regulation of alternative promoter usage, resulting in light-dependent protein isoforms with altered subcellular localization that help the plant respond metabolically to fluctuating light conditions.
