National Center for Biotechnology Information 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.
