Websignal is a fundamental question in biology. Phytochromeare the main red light sensors in plants and s phytochromes form small (~40nm) subnuclear bodies, which also contain supporting cofactors and downstream transcription factors. These subnuclear structures are called photobodies and they play an important role in regulating light responses. WebLight perception is therefore very important for plants, so they have evolved photoreceptors to sense light (quality) and act upon it.
