Photomorphogenesis is the process by which plants and some fungi respond to light during their growth and development. This phenomenon involves changes in morphology, such as stem elongation, leaf expansion, and flowering, all influenced by the quality, quantity, and duration of light exposure. Light receptors, including phytochromes and cryptochromes, play a crucial role in detecting light signals. These receptors trigger various biochemical pathways that help the plant adapt to its environment, ensuring optimal growth and survival. Understanding photomorphogenesis is essential for improving agricultural practices and enhancing crop yields.
