WebHence, 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 … 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 ...

Out of the Dark and Into the Light: A New View of Phytochrome Photobodies

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. ... Chen, Meng … 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.
