Photobodies in light signaling
WebApr 10, 2024 · Photoactivated phyB proteins spontaneously form subnuclear condensates photobodies (PBs) [85]. PB formation is also driven by LLPS. In the PB, phytochromes interact with signaling components to transcriptionally regulate light-responsive genes and initiate a wide range of light-dependent responses [86, 87].

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.
