Blue light sensory systems in plants.
Plant development is influenced by many environmental stimuli, including light, temperature and gravity. Of these stimuli, light is of particular importance because plants depend on it for energy and, thus, for survival. Moreover, virtually all stages of plant development are regulated in part by light through the action of various photosensory systems. Examples of light-regulated processes include germination, stem growth, leaf and root development, tropic responses and flower induction. This review provides an analysis of recent investigations of blue light sensory systems in plants. Current results suggest that plants respond to blue light through a complex photosensory network that incorporates the action of multiple blue light perception systems.
