FIN5 Positively Regulates Far-red Light Responses in Arabidopsis thaliana [PDF]

Plant and Cell Physiology, 2003
We report the characterization of a semi-dominant mutation fin5-1 (far-red insensitive 5-1) of Arabidopsis, which was isolated from genetic screening of phytochrome A (phyA) signaling components. Plants with the fin5-1 mutation exhibited a long hypocotyl phenotype when grown under far-red (FR) light, but not under red light.

Supplemental Far-red Light-emitting Diode Light Increases Growth of Foxglove Seedlings Under Sole-source Lighting

HortTechnology, 2020
Seedlings may be grown indoors where environmental conditions can be precisely controlled to ensure consistent and reliable production. The optimal spectrum for production under sole-source lighting is currently unknown.

Phytochromes A and B Mediate Light Stabilization of BIN2 to Regulate Brassinosteroid Signaling and Photomorphogenesis in Arabidopsis

Frontiers in Plant Science, 2022
Phytochromes A and B (phyA and phyB) are the far-red and red lights photoreceptors mediating many light responses in Arabidopsis thaliana. Brassinosteroid (BR) is a pivotal phytohormone regulating a variety of plant developmental processes including ...

Adventitious rooting of Chrysanthemum is stimulated by a low red:far-red ratio [PDF]

, 2019
Adventitious rooting, a critical process in the vegetative propagation of many ornamentals, can be affected by both light intensity and light quality.

Harvesting Far-Red Light with Plant Antenna Complexes Incorporating Chlorophyll d [PDF]

Biomacromolecules, 2021
Increasing the absorption cross section of plants by introducing far-red absorbing chlorophylls (Chls) has been proposed as a strategy to boost crop yields. To make this strategy effective, these Chls should bind to the photosynthetic complexes without altering their functional architecture.

Acclimation to white light in a far-red light specialist: insights from Acaryochloris marina MBIC11017. [PDF]

New Phytol
Summary The Chl d‐containing cyanobacterium, Acaryochloris marina MBIC11017, is constitutively adapted to far‐red light (FRL). However, it occasionally encounters white light (WL) in its natural habitat. Using biochemical and spectroscopic techniques, we investigated how this organism acclimates to WL and analysed the excitation energy trapping ...

Supplemental Low-Irradiance Mono/Polychromatic LED Lighting Significantly Enhances Floral Biology of the Long-Day F1 Hybrid Strawberry ‘Soraya’ (Fragaria x ananassa Duch.)

International Journal of Plant Biology
Floral and vegetative responses of the strawberry (Fragaria x ananassa Duch.) to specific light wavelengths are not well documented. LED lights make it feasible for precise exposure to specific wavelengths during a 24 h cycle to alter growth responses ...

Far-red light is needed for efficient photochemistry and photosynthesis [PDF]

Journal of Plant Physiology, 2017
The efficiency of monochromatic light to drive photosynthesis drops rapidly at wavelengths longer than 685nm. The photosynthetic efficiency of these longer wavelengths can be improved by adding shorter wavelength light, a phenomenon known as the Emerson enhancement effect.

A higher far-red intensity promotes the transition to flowering in triticale grown under speed breeding conditions

Вавиловский журнал генетики и селекции
It typically takes 12 to 15 years to develop a new promising variety. One of the ways to reduce this time is through speed breeding. This method allows for up to six consecutive generations of spring cereals in a single year.

Increasing the Nighttime Lighting Duration Can Hasten Flowering of Long-day Plants

HortScience
Low-intensity (≈2 μmol·m−2·s−1) photoperiodic lighting is often delivered at night to promote flowering of long-day greenhouse ornamentals when natural daylengths are short.
