title: Light, phytochrome signalling and photomorphogenesis in Arabidopsis.
abstract: The phytochromes is a family of plant photoreceptors that control growth and development in response to environmental cues. Red and far-red light are the most efficient wavebands to induce conformational changes of phytochromes and consequently modify their kinetics, nuclear/cytoplasmic partitioning, ability to phosphorylate substrates, and physical interaction with proteins that bind DNA. Many players in phytochrome signalling have been identified and a complex, highly regulated network is envisaged. Here we describe the connection between different features of the phytochrome signalling network and the versatile relationship between light signals and physiological outputs shown by phytochromes.
