Red light activatable chemo-optogenetic dimerization regulates cell apoptosis [PDF]

, 2023
We report a non-phototoxic and non-photobleaching chemo-optogenetic dimerizer that effectively regulates protein-protein proximity inside living cells using far-red light.

The effect of storage and different red and far red light treatments on Catalpa ovata g. don seed germination [PDF]

Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2022
Chinese catalpa is a medicinal and ornamental, low demanding tree which tolerates urban pollution, drought and poor soils. It should be planted more often in Serbia, and gen­erative propagation is the most suitable method for mass production of ...

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 ...

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.

Leaf morphology, optical characteristics and phytochemical traits of butterhead lettuce affected by increasing the far-red photon flux

Frontiers in Plant Science, 2023
Light and its spectral characteristics are crucial for plant growth and development. The far-red photon flux mediates many plant processes through the action of phytochrome and also accelerates the photosynthetic electron transfer rate. In this study, we

Far-red light intensity controls biofilm formation.

, 2019
(A) Colony biofilm phenotypes are shown for WT PA14 and the designated mutants on Congo red agar medium after 72 h of growth under the indicated far-red light intensities. Scale bar is 2 mm for all images.

Effects of light and phytochrome in heterotrophic growth of Lemna minor L. [PDF]

, 1976
Axenic cultures of Lemna minor L. were grown on a medium containing sugars and amino acids. In continuous darkness the growth rate was one-tenth of the maximum in continuous light.

An integrative model for phytochrome B mediated photomorphogenesis:from protein dynamics to physiology [PDF]

, 2010
Plants have evolved various sophisticated mechanisms to respond and adapt to changes of abiotic factors in their natural environment. Light is one of the most important abiotic environmental factors and it regulates plant growth and development ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating the influence of varied ratios of red and far-red light on lettuce (Lactuca sativa): effects on growth, photosynthetic characteristics and chlorophyll fluorescence

Frontiers in Plant Science
Far red photon flux accelerates photosynthetic electron transfer rates through photosynthetic pigments, influencing various biological processes. In this study, we investigated the impact of differing red and far-red light ratios on plant growth using ...
