Studies on phytochrome. Some properties of electrophoretically pure phytochrome [PDF]

Biochemical Journal, 1970
1. Phytochrome was purified from etiolated oat (Avena sativa) seedlings either by gel-filtration chromatography and ion-exchange chromatography or by gel-filtration chromatography and calcium phosphate chromatography. Differences were observed in the spectral properties of phytochrome isolated by the two methods. 2.

Time‐Resolved Native Mass Spectrometry Reveals Reversible Light‐Driven Oligomerization of Arabidopsis Cryptochrome 1 and Its Antagonism by BIC1

Angewandte Chemie International Edition, EarlyView.
Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...

Increasing ambient temperature progressively disassembles Arabidopsis phytochrome B from individual photobodies with distinct thermostabilities. [PDF]

, 2020
Warm temperature is postulated to induce plant thermomorphogenesis through a signaling mechanism similar to shade, as both destabilize the active form of the photoreceptor and thermosensor phytochrome B (phyB).

An angle balanced polarization resolved femtosecond VIS pump–IR probe study [PDF]

, 2013
Photoisomerization of biliverdin (BV) chromophore triggers the photoresponse in native Agp1 bacteriophytochrome. We discuss heterogeneity in phytochrome Pr form to account for the shape of the absorption profile.

Structural basis for light control of cell development revealed by crystal structures of a myxobacterial phytochrome

IUCrJ, 2018
Phytochromes are red-light photoreceptors that were first characterized in plants, with homologs in photosynthetic and non-photosynthetic bacteria known as bacteriophytochromes (BphPs).

Influence of phytochromes on microRNA expression, phenotype, and photosynthetic activity in A. thaliana phy mutants under light with different spectral composition

Photosynthetica, 2023
Light-induced changes in miRNAs, morphogenesis, and photosynthetic processes in phytochrome-deficient mutant plants grown under different light qualities were studied.

Integrating tunable LED‐induced plant responses with novel solar cell technologies for energy‐efficient agrivoltaic systems

PLANTS, PEOPLE, PLANET, EarlyView.
The increasing demand for sustainable food production requires innovative solutions that balance productivity, resource efficiency, and environmental impact. Vertical Farming Systems (VFSs) offer a promising approach; however, their high energy consumption remains challenging.

Plant responses to photoperiod [PDF]

, 2009
Photoperiod controls many developmental responses in animals, plants and even fungi. The response to photoperiod has evolved because daylength is a reliable indicator of the time of year, enabling developmental events to be scheduled to coincide with ...
