Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling [PDF]

Nature Communications, 2019
Light initiates chloroplast biogenesis by controlling gene expression in plastids. Here Yoo et al. show that nuclear phytochrome signaling triggers plastid gene expression via a novel dual-localized protein necessary for nuclear phytochrome signaling and

NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches [PDF]

Nature Communications, 2019
Phytochrome signaling in the nucleus can activate expression of photosynthesis-associated genes in plastids. Here Yang et al. show that NCP is a dual-targeted protein that promotes phytochrome B localization to photobodies in the nucleus while ...

Phytochromes and Phytochrome Interacting Factors [PDF]

Plant Physiology, 2017
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]

Plant Physiology, 1979
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.

Decision-making in serial crystallography: a simple test to quickly determine whether sufficient data have been collected. [PDF]

Acta Crystallogr D Struct Biol
We describe a simple test to determine whether sufficient data have been collected during a serial crystallographic experiment, and its incorporation into the autoprocessing pipeline at the T‐REXX endstation on beamline P14 at the PETRA III synchrotron.In standard rotational data collection for macromolecular crystallography, data are normally ...

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)-

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 ...

Daytime temperature is sensed by phytochrome B in Arabidopsis through a transcriptional activator HEMERA. [PDF]

, 2019
Ambient temperature sensing by phytochrome B (PHYB) in Arabidopsis is thought to operate mainly at night. Here we show that PHYB plays an equally critical role in temperature sensing during the daytime.

Comparative analysis of two phytochrome mutants of tomato (Micro-Tom cv.) reveals specific physiological, biochemical, and molecular responses under chilling stress

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.

Participation of labile and stabile phytochrome in the control of chlorophyll accumulation during the deetiolation of oat seedlings

Acta Societatis Botanicorum Poloniae, 2014
The effect of the phytochrome system on the accumulation rate of chlorophyll-a and b in 96-hour-old oat seedlings during the first 3 hours of white light action was investigated.
