Web(nuclear localization signal), a NES (nuclear export signal) and a phyA binding site in their N-terminal half. This short domain is both necessary and sufﬁcient for the full functionality of these molecules (Genoud etal., 2008). FHY1andFHL co-localize with phyA in the nucleus and in photobodies and interact with phyA 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.
