Phytochromes and Phytochrome Interacting Factors [PDF]
The basic helix-loop-helix domain-containing transcription factors that interact physically with the red and far-red light photoreceptors, phytochromes, are called PHYTOCHROME INTERACTING FACTORS (PIFs). In the last two decades, the phytochrome-PIF signaling module has been shown to be conserved from Physcomitrella patens to higher plants.

Phytochrome Radioimmunoassay [PDF]
A phytochrome radioimmunoassay with a detection limit of about 2 nanograms has been developed. The radioimmunoassay does not suffer from the potential drawbacks of the commonly used spectral assay and requires less than 1 microliter of crude extract from dark-grown plants for quantitation of phytochrome.

Immunochemistry of Phytochrome [PDF]
Rabbit antibody was elicited against purified oat phytochrome polypeptides. Immunodiffusion and immunoelectrophoresis indicated the antibody elicited was predominantly a single precipitin system. No antigenic difference was detected between red-absorbing phytochrome and far red-absorbing phytochrome.

The Chromophore of Phytochrome [PDF]
The chromophore of phytochrome, the plant photomorphogenic pigment, was cleaved from the associated protein. Chromatographic and spectral properties indicated that it was a bilitriene closely similar to but distinct from the chromophore of C-phycocyanin and allophycocyanin.

Cucumber leaf necrosis caused by radiation with abrupt increase of far-red component
Plants exhibit morphological plasticity in response to changes in the proportion of far-red radiation (FR). However, little is known about the response to a sudden increase of FR component. Cucumber seedlings were acclimatized to radiation without FR (FR-

Irradiation with red light leads to the formation of an unstable, undergoing gradual destruction, physiologically active PFR form of phytochrome in the coleoptiles of oat seedlings.

Background Phytochromes are plant photoreceptors that have long been associated with photomorphogenesis in plants; however, more recently, their crucial role in the regulation of variety of abiotic stresses has been explored.

Far-red Fraction: An Improved Metric for Characterizing Phytochrome Effects on Morphology
Phytochrome, a well-studied photoreceptor in plants, primarily absorbs in the red (R) and far-red (FR) regions and is responsible for the perception of shade and subsequent morphological responses.
