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]. WebThe current developments in light signaling with a major focus on UV-B mediated plant growth regulation are outlined, which is an integration of its crosstalks with both environmental factors and phytohormones. ... Photobodies are explored as environmental sensors, the role of their protein constituents are examined, and the biophysical ...

Webcontaining nuclear bodies, or "photobodies," found in plants are a unique type of subnuclear domain whose size, number, and potentially function are directly regulated by external … 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.
WebPCH1 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 ... WebMar 29, 2024 · Three recently characterized proteins with dual nuclear‐plastid localization essential for the formation of photobodies and consequently also for light signaling and chloroplast biogenesis are: HEMERA (HMR), REGULATOR OF CHLOROPLAST BIOGENESIS (RCB) and NUCLEAR CONTROL OF PEP ACTIVITY (NCP) (Fig. 2).
WebNov 1, 2011 · The localization of phyB to photobodies is triggered by R light. In contrast, phyA photobody localization is triggered by. Down-regulation of phyA and phyB in the light. Both phyA and phyB levels are repressed in the light to desensitize or regulate phy signaling [61]. During the dark-to-R-light transition, phyA levels are rapidly reduced by 50 ... WebJul 1, 2024 · This hypothesis has been formulated on the basis of the PI's previous molecular genetic studies on two novel light signaling components required for photobody biogenesis, named HEMERA and HERMES, and on the preliminary result showing that a subset of light-responsive genes are spatially positioned to photobodies. ...

WebAug 9, 2013 · Hence, currently available evidence is consistent with photobodies consisting of proteins in aggregates destined for dismantling and thus the deactivation of the light-activated signaling pathway. Formation of phytochrome photobodies appears to depend on participation of several other proteins, one of which is a polyubiquitin-binding protein ...
WebNov 1, 2011 · Both phyA and phyB are turned-over by the same mechanism to desensitize phy signaling in the light. Third, at the cellular level, phys rapidly accumulate in the nucleus and are compartmentalized to photobodies in the light.
