Plants, 2021 Light-emitting diodes allow for the application of specific wavelengths of light to induce various morphological and physiological responses. In lettuce (Lactuca sativa), far-red light (700–800 nm) is integral to initiating shade responses which can ...

Far-red Photons Increase Light Capture but Have Lower Photosynthetic Capacity Than Red Photons
Journal of the American Society for Horticultural Science, 2023 Far-red photons (700–750 nm) can accelerate crop growth during indoor production through both physiological and morphological processes. A previous study showed that far-red photons can drive photosynthesis with efficiency similar to that of ...

The effect of red light on the germination of a Brazilian Pteridophyte
Brazilian Archives of Biology and Technology, 1999 The effects of red light on the germination of spores of Cheilantes concolor Langsd & Fisch were investigated in this study. The spores were spread in the Mohr (1956) nutritional solution after Dyer’s modifications (1979).

A red/far-red light-responsive bi-stable toggle switch to control gene expression in mammalian cells [PDF]
, 2013 Growth and differentiation of multicellular systems is orchestrated by spatially restricted gene expression programs in specialized subpopulations. The targeted manipulation of such processes by synthetic tools with high-spatiotemporal resolution could ...

Identification of Cyanobacteriochromes Detecting Far-Red Light
Biochemistry, 2016 The opacity of mammalian tissue to visible light and the strong attenuation of infrared light by water at ≥900 nm have contributed to growing interest in the development of far-red and near-infrared absorbing tools for visualizing and actuating responses within live cells. Here we report the discovery of cyanobacteriochromes (CBCRs) responsive to light

Far-Red Light Accelerates Photosynthesis in the Low-Light Phases of Fluctuating Light [PDF]
Plant and Cell Physiology, 2019 Abstract It is well known that far-red light (FR; >700 nm) drives PSI photochemistry, but its effect on photosynthetic performance has received little attention. In this study, the effects of the addition of FR to red fluctuating light (FL) have on photosynthesis were examined in the leaves of Arabidopsis thaliana.

LAF1, a MYB transcription activator for phytochrome A signaling [PDF]
, 2001 The photoreceptor phytochrome (phy) A has a well-defined role in regulating gene expression in response to specific light signals. Here, we describe a new Arabidopsis mutant, laf1 (long after far-red light 1) that has an elongated hypocotyl specifically ...

Horticulturae, 2020 Although light-emitting diode (LED) lamps have been broadly applied in horticultural production to improve plant yield and quality, compared to natural light there is a disadvantage in the lack of far-red light in the LED spectrum. Far-red light has been

670 nm light mitigates oxygen-induced degeneration in C57BL/6J mouse retina [PDF]
, 2016 BACKGROUND Irradiation with light wavelengths from the far red (FR) to the near infrared (NIR) spectrum (600 nm -1000 nm) has been shown to have beneficial effects in several disease models.
