Journal of Genetic Engineering and Biotechnology, 2020 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
Journal of the American Society for Horticultural Science, 2020 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.

Conditional circadian regulation of PHYTOCHROME A gene expression [PDF]
, 2001 The phytochrome photoreceptors and the circadian clock control many of the same developmental processes, in all organs and throughout the growth of Arabidopsis plants. Phytochrome A (phyA) provides light input signals to entrain the circadian clock.

Infrared spectroscopy of phytochrome and model pigments [PDF]
, 1990 Fourier-transform infrared difference spectra between the red-absorbing and far-red-absorbing forms of oat phytochrome have been measured in H2O and 2H2O. The difference spectra are compared with infrared spectra of model compounds, i.e. the (5Z,10Z,15Z)-

Long-Distance Protonation-Conformation Coupling in Phytochrome Species
Molecules, 2022 Phytochromes are biological red/far-red light sensors found in many organisms. The connection between photoconversion and the cellular output signal involves light-mediated global structural changes in the interaction between the photosensory module (PAS-

Tyrosine 263 in Cyanobacterial Phytochrome Cph1 Optimizes Photochemistry at the prelumi-R→lumi-R Step [PDF]
, 2014 We report a low-temperature fluorescence spectroscopy study of the PAS-GAF-PHY sensory module of Cph1 phytochrome, its Y263F mutant (both with known 3D structures) as well as Y263H and Y263S to connect their photochemical parameters with intramolecular ...

PPKs mediate direct signal transfer from phytochrome photoreceptors to transcription factor PIF3
Nature Communications, 2017 Phytochrome photoreceptors mediate degradation of PIF transcription factors in the nucleus in response to light. Here Niet al. identify a family of nuclear protein kinases that interact with photoactivated phytochrome B and facilitate phytochrome-induced
