Phytochrome-interacting factors

Seminars in Cell & Developmental Biology, 2000
The phytochrome family of sensory photoreceptors transduces environmental light signals to responsive nuclear genes by poorly defined pathways. The recent application of yeast two-hybrid library screens to the identification of components that physically interact with members of the phytochrome family has dramatically altered previous views of the ...

PHOTOTRANSFORMATIONS OF PHYTOCHROME

Photochemistry and Photobiology, 1977
Abstract— –Phytochrome is the photoreversible chromoprotein that controls many aspects of plant growth and development Phototransformations of the red absorbing form (Pr) and the far red absorbing form (Pfr) involve initial photoreactions followed by dark relaxation reactions.

From phytochrome to phytochromes

1994
Abstract Plants are bound to a particular site for their lifetime. As a living system lacking mobility, the ability to sense and subsequently to react properly to dramatic environmental changes is a crucial prerequisite for survival. Light is probably the most important environmental stimulus to which plants react: it is not only the ...

Photoprotection of phytochrome

Planta, 1988
High-fluence-rate white light is shown to retard the degradation of phytochrome in etiolated seedlings of four different species: Amaranthus caudatus, Phaseolus radiatus (mung bean), Pisum sativum (garden pea), and Avena sativa (oat). In Amaranthus, a high photon fluence rate (approx.

Phytochrome degradation

Plant, Cell & Environment, 1997
ABSTRACTPlants actively modulate the levels of the various phyto‐chrome isoforms during their life cycle to optimize light absorption and perception. For phytochrome A (phyA), one of the most influential methods of control is selective turnover of the photoreceptor upon photoconversion from the red‐absorbing form (Pr) to the far‐red‐absorbing form (Pfr)

Phytochrome Cytoplasmic Signaling

Annual Review of Plant Biology, 2013
Extensive studies in both lower and higher plants indicate that plant phytochrome photoreceptors signal not only by regulating transcription in the nucleus but also by acting within the cytoplasm, the latter signaling routes acting within minutes or even seconds and also providing directional information.

THE PHYTOCHROME CHROMOPHORE

2006
For vision to occur, light absorption is an absolute physical requirement. The array of photomorphogenic responses all has one thing in common: these processes are initiated only after photo excitation of a holoprotein. These holoproteins generally contain a polypeptide component and a small, light-absorbing ligand termed the chromophore.
