Horticulturae, 2023 Far-red light was excluded in photosynthetic photon flux; however, recent studies have shown that it increases photosynthetic capacity. In addition, there were few studies on the whole canopy photosynthetic rate and continuous changes of morphology on ...

The structure of a far-red fluorescent protein, AQ143, shows evidence in support of reported red-shifting chromophore interactions [PDF]
, 2014 Engineering fluorescent proteins (FPs) to emit light at longer wavelengths is a significant focus in the development of the next generation of fluorescent biomarkers, as far-red light penetrates tissue with minimal absorption, allowing better imaging ...

Long-term optical variability of PKS 2155-304 [PDF]
, 2010 Aims: The optical variability of the blazar PKS 2155-304 is investigated to characterise the red noise behaviour at largely different time scales from 20 days to O(>10 yrs).

Visible light communication with efficient far-red/near-infrared polymer light-emitting diodes [PDF]
Light: Science & Applications, 2020 AbstractVisible light communication (VLC) is a wireless technology that relies on optical intensity modulation and is potentially a game changer for internet-of-things (IoT) connectivity. However, VLC is hindered by the low penetration depth of visible light in non-transparent media.

Induction Kinetics of Photosystem I-Activated P700 Oxidation in Plant Leaves and Their Dependence on Pre-Energization [PDF]
, 2010 Absorbance changes ¿A 810 were measured in pea (Pisum sativum L., cv. Premium) leaves to track redox transients of chlorophyll P700 during and after irradiation with far red (FR) light under various preillumination conditions in the absence and presence ...

Far-Red Light Acclimation for Improved Mass Cultivation of Cyanobacteria [PDF]
Metabolites, 2019 Improving mass cultivation of cyanobacteria is a goal for industrial biotechnology. In this study, the mass cultivation of the thermophilic cyanobacterium Chlorogloeopsis fritschii was assessed for biomass production under light-emitting diode white light (LEDWL), far-red light (FRL), and combined white light and far-red light (WLFRL) adaptation.

Photosynthetic activity of far-red light in green plants
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2005 We have found that long-wavelength quanta up to 780 nm support oxygen evolution from the leaves of sunflower and bean. The far-red light excitations are supporting the photochemical activity of photosystem II, as is indicated by the increased chlorophyll fluorescence in response to the reduction of the photosystem II primary electron acceptor, Q(A ...
