Photomophogenesis: Phytochrome takes a partner!
How light signals are transduced by phytochromes is still poorly understood. Recent studies have provided evidence that a PAS domain protein, PIF3, physically interacts with phytochromes, plays a role in phytochrome signal transduction and might be a component of a novel signalling pathway in plants.
