Abstract

Light is one of the key environmental signals regulating plant growth and development. Therefore, understanding the mechanisms by which light controls plant development has long been of great interest to plant biologists. Traditional genetic and molecular approaches have successfully identified key regulatory factors in light signaling, but recent genomic studies have revealed massive reprogramming of plant transcriptomes by light, identified binding sites across the entire genome of several pivotal transcription factors in light signaling, and discovered the involvement of epigenetic regulation in light-regulated gene expression. This review summarizes the key genomic work conducted in the last decade which provides new insights into light control of plant development.

Keywords: light control of plant development, photomorphogenesis, gene expression, epigenomic regulation, transcription factors
