WebAug 31, 2024 · In response to red light, phytochromes convert to a biologically active form, translocating from the cytoplasm into the nucleus and further compartmentalizes into subnuclear compartments termed photobodies. PhyB photobodies regulate phytochrome-mediated signaling and physiological outputs. WebFeb 3, 2016 · PCH1 peaks at dusk, binds phytochrome B (phyB) in a red light-dependent manner, and co-localizes with phyB into photobodies. PCH1 is necessary and sufficient to promote the biogenesis of large photobodies to maintain an active phyB pool after light exposure, potentiating red-light signaling and prolonging memory of prior illumination. open bip file online

WebFeb 1, 2013 · Independent of the exact function of phytochrome-associated photobodies in mediating light signaling, our data clearly suggest a new paradigm by which phosphorylation modulates activity of phyB. At present, we are unable to determine whether phosphorylation of Ser-86 is due to phyB autophosphorylation or the activity of an unknown kinase. Webproteins for light-signaling pathways in plants. What initiates the formation of photobodies is poorly understood. Here we develop a nucleolar marker protein nucleolin2 (Nuc2)–based method called the nucleolus-tethering system (NoTS) by artificially tethering a protein of in-terest to the nucleolus to analyze the initiation of photobodies.
