Far-red light allophycocyanin subunits play a role in chlorophyll d accumulation in far-red light
Photosynthesis Research, 2019Some terrestrial cyanobacteria acclimate to and utilize far-red light (FRL; λ = 700-800 nm) for oxygenic photosynthesis, a process known as far-red light photoacclimation (FaRLiP). A conserved, 20-gene FaRLiP cluster encodes core subunits of Photosystem I (PSI) and Photosystem II (PSII), five phycobiliprotein subunits of FRL-bicylindrical cores, and ...

Green light augments far-red-light-induced shade response
Plant Growth Regulation, 2015Plants grown in shade exhibit changes in architecture and gene expression to best accommodate growth in photosynthetically challenging conditions. Adaptive changes in morphology include stem and petiole elongation and leaf hyponasty. These changes can be induced by low red to far-red ratio (R/Fr ratio) or by enrichment of green light relative to red ...

Far-red light photoadaptations in aquatic cyanobacteria
Hydrobiologia, 2018Aquatic ecosystems depend on photosynthetic bacteria that use various strategies of adaptation to light quantity and quality; the qualitative strategies include far-red/near infrared (> 700 nm) light adaptations. The usage of > 700 nm light as energy source is disadvantageous for photosynthesis (long-wavelength quanta are poorer in energy than short ...

Far-red light acclimation in diverse oxygenic photosynthetic organisms
Photosynthesis Research, 2019Oxygenic photosynthesis has historically been considered limited to be driven by the wavelengths of visible light. However, in the last few decades, various adaptations have been discovered that allow algae, cyanobacteria, and even plants to utilize longer wavelength light in the far-red spectral range.

The structural basis of far-red light absorbance by allophycocyanins
Photosynthesis Research, 2020Phycobilisomes (PBS), the major light-harvesting antenna in cyanobacteria, are supramolecular complexes of colorless linkers and heterodimeric, pigment-binding phycobiliproteins. Phycocyanin and phycoerythrin commonly comprise peripheral rods, and a multi-cylindrical core is principally assembled from allophycocyanin (AP).

The Journal of Horticultural Science and Biotechnology, 2003
SummaryPotted bulbs of ‘Nellie White’, ‘Sunray’ and ‘Stargazer’ representing three lily hybrids [Easter (Lilium longiflorum Thunb.), Asiatic and Oriental, respectively], were forced in a glass greenhouse under three lighting regimes namely, 8.h photoperiod (8 PP) by using blackout between 1600 hours and 0800 hours to eliminate twilight; 8 PP extended ...

Abscission: Response to Red and Far-Red Light
Journal of Experimental Botany, 1987Craker, L. E., Zhao, S. Y. and Decoteau, D. R. 1987. Abscission: response to red and far-red light.—J. exp. Bot. 38: 883-888. The dose-response and time relationship of red and far-red light in the inhibition and promotion, respectively, of dark-induced leaf abscission was quantified using cuttings of coleus (Coleus Blumei Benth.).

Molecular mechanisms and ecological function of far‐red light signalling
Plant, Cell & Environment, 2017AbstractLand plants possess the ability to sense and respond to far‐red light (700–760 nm), which serves as an important environmental cue. Due to the nature of far‐red light, it is not absorbed by chlorophyll and thus is enriched in canopy shade and will also penetrate deeper into soil than other visible wavelengths.

Far-red light-insensitive, phytochrome A-deficient mutants of tomato
Molecular and General Genetics MGG, 1995We have selected two recessive mutants of tomato with slightly longer hypocotyls than the wild type, one under low fluence rate (3 mumol/m2/s) red light (R) and the other under low fluence rate blue light. These two mutants were shown to be allelic and further analysis revealed that hypocotyl growth was totally insensitive to far-red light (FR).

Methylene blue as a far-red light-mediated photocleavable multifunctional ligand
Chemical Communications, 2020Methylene blue (MB) was discovered as a multifunctional far-red photocleavable ligand capable of rendering a series of MB conjugated compounds with off-to-on fluorescence switch, photodynamic therapy and triggered release of conjugated molecule.
