Nuclear Phytochrome B Regulates Leaf Flattening through Phytochrome Interacting Factors

Dear Editor, Plants are equipped with an array of photoreceptors to measure UV-B,blue,red,and far-red light in order to monitor their light environment.However,although both synergistic and antagonistic interactions have been described between blue and red light signals (Casal,2000),little is known about how different light signals are integrated into modulate plant growth and development.
