Far-Red Light Effects on Lettuce Growth and Morphology in Indoor Production Are Cultivar Specific
Plants, 2022 Understanding crop responses to the light spectrum is critical for optimal indoor production. Far-red light is of particular interest, because it can accelerate growth through both physiological and morphological mechanisms.

Molecular Evolution of Far-Red Light-Acclimated Photosystem II
Microorganisms, 2022 Cyanobacteria are major contributors to global carbon fixation and primarily use visible light (400−700 nm) to drive oxygenic photosynthesis. When shifted into environments where visible light is attenuated, a small, but highly diverse and widespread ...

Extensive remodeling of a cyanobacterial photosynthetic apparatus in far-red light [PDF]
Science, 2014 Making sure leftover light gets in Bacteria that harvest sunlight through photosynthesis are everywhere and are vital for absorbing carbon dioxide. Like plants in a jungle, these cells have to compete for access to light. Gan et al.

Occurrence of Far-Red Light Photoacclimation (FaRLiP) in Diverse Cyanobacteria [PDF]
Life, 2014 Cyanobacteria have evolved a number of acclimation strategies to sense and respond to changing nutrient and light conditions. Leptolyngbya sp. JSC-1 was recently shown to photoacclimate to far-red light by extensively remodeling its photosystem (PS) I ...

Erythrocytic bioactivation of nitrite and its potentiation by far-red light
Redox Biology, 2019 Background: Nitrite is reduced by heme-proteins and molybdenum-containing enzymes to form the important signaling molecule nitric oxide (NO), mediating NO signaling. Substantial evidence suggests that deoxygenated hemoglobin within red blood cells (RBCs)

Synthesis of C8-Vinyl Chlorophylls d and f Impairs Far-Red Light Photoacclimation and Growth Under Far-Red Light. [PDF]
Physiol PlantABSTRACT The inducible biosynthesis of chlorophyllsdandfenables a subset of specialised cyanobacteria to perform oxygenic photosynthesis under far-red light—in the absence of visible wavelengths—via a process termed far-red light photoacclimation. These pigments, like the more common chlorophyllsaandb, typically carry an ethyl substituent at the C8 ...

Far-red light orchestrates antiviral defense in plants. [PDF]
Sci AdvLight undergoes dramatic spectral shifts at dusk (sunset) and dawn (sunrise), enhancing insect activity and increasing the risk of insect-borne virus transmission. However, how plants respond to these light changes and associated viral threats remains unclear.

The Electronic Origin of Far‐Red‐Light‐Driven Oxygenic Photosynthesis [PDF]
Angewandte Chemie, 2022 AbstractPhotosystem‐II uses sunlight to trigger charge separation and catalyze water oxidation. Intrinsic properties of chlorophyll a pigments define a natural “red limit” of photosynthesis at ≈680 nm. Nevertheless, charge separation can be triggered with far‐red photons up to 800 nm, without altering the nature of light‐harvesting pigments.
