Significance In Arabidopsis , phytochrome B (phyB) perceives light and temperature signals to regulate various fundamental morphogenic processes in plants through its interconversion between active Pfr inactive Pr states. On photoconversion from Pfr, phyB forms subnuclear foci called photobodies, whose compositions molecular functions are unclear. We show here that the phyB-interacting protein PCH1 is a structural component of photobodies protects thermal reversion back Pr, thereby helping...
Many aspects of photoperception by plants and microorganisms are initiated the phytochrome (Phy) family photoreceptors that detect light through interconversion between red light- (Pr) far-red light-absorbing (Pfr) states. Plants synthesize a small Phy isoforms (PhyA to PhyE) collectively regulate photomorphogenesis temperature perception redundant unique actions. While selective roles these have been partially attributed their differing abundances, expression patterns, affinities for...
Phytochromes (Phys) encompass a diverse collection of bilin-containing photoreceptors that help plants and microorganisms perceive light through photointerconversion between red (Pr) far-red (Pfr)-absorbing states. In addition, Pfr reverts thermally back to Pr via highly enthalpic process enables temperature sensation in possibly other organisms. Through domain analysis the Arabidopsis PhyB isoform assembled recombinantly, coupled with measurements solution size, photoconversion, thermal...
Abstract The phytochrome (phy) family of bilin-containing photoreceptors are major regulators plant photomorphogenesis through their unique ability to photointerconvert between a biologically inactive red light-absorbing Pr state and an active far-red lightabsorbing Pfr state. While the initial steps in signaling unclear, early event for phyB isoform after photoconversion is its redistribution from cytoplasm into subnuclear foci named photobodies (PBs) that dissipate reverts back by...
