Shedding light on the chloroplast as a remote control of nuclear gene expression
Plants rely on a sophisticated light sensing and signaling system that allows them to respond to environmental changes. Photosensory protein systems -phytochromes, cryptochromes, phototropins, and ultraviolet (UV)-B photoreceptors- have evolved to let plants monitor light conditions and regulate dif...
