Photomorphogenesis refers to the process by which plants regulate their growth and development in response to light. It plays a crucial role in various aspects of plant life, including seed germination, stem elongation, leaf expansion, and flowering. Synonymously known as light-mediated growth, photomorphogenesis encompasses the intricate mechanisms that enable plants to sense and interpret various light signals. This process involves a series of photoreceptors, which detect different wavelengths of light, such as red and blue light. These photoreceptors initiate chemical reactions that ultimately influence the expression of genes responsible for plant development. Understanding photomorphogenesis is vital for optimizing agricultural practices and enhancing crop yields in controlled environments.
