Photomorphogenesis and Photoreceptors in Plants: A Review

Chhavi Jain

Abstract


Plants are essential for the survival of living beings on Earth. But how the growth and development of plants is regulated is something which is important to be understood. Several factors regulate the plant growth and development including hormonal as well as environmental factors. Among the environmental factors, light plays crucial role for the growth of plants. This branch of science that deals with the study of growth and development of plants in response to light is termed as ‘photomorphogenesis’. Here, in this review, we have highlighted the various biological processes in plants that are regulated by light and the photoreceptors that are involved in these activities.

Keywords: Cryptochromes, photomorphogenesis, photoreceptors, phytochromes
