Light signaling

 
 Light signaling
 Background
Many organisms have developed various strategies for perceiving and processing environmental light information to optimize their growth, development, and behavior. Plants, being photosynthetic and sessile, exhibit particularly plastic development and growth, depending on the environmental light information. The quality, intensity, duration, and direction of the environmental light provide plants with information not only on the ambient light condition but also on other elements in their environments such as neighboring plants and seasonal changes. Thus, plants possess a sophisticated light sensing and signaling system that ensures optimal photoperception and responses to their ever-changing environmental conditions. The light-sensing system in plants includes multiple photoreceptors; the UV-B receptor, the UV-A/blue light receptors, and phytochromes.
