WebJan 1, 2001 · The Lagarias laboratory recently has provided convincing evidence that phytochrome functions as a photoreceptor kinase (an unusual Ser/Thr kinase with two His kinase-like domains; 25). WebPhytochromes are proteinaceous plant pigments which are light-sensitive. These photo-sensitive pigments act as receptors which help the plant detect incident light. There are several types of phytochromes present within a plant that either work independently of each other or can work together in the photomorphogenesis process.
