Light is essential for photosynthesis. Nevertheless, its intensity widely changes depending
on time of day, weather, season, and localization of individual leaves within canopies. This …

Ultraviolet-B (UV-B) radiation is an intrinsic fraction of sunlight that plants perceive through
the UVR8 photoreceptor. UVR8 is a homodimer in its ground state that monomerizes upon …

Non-photochemical quenching (NPQ) of chlorophyll fluorescence is a valuable feature for
the study of photosynthetic organisms' light utilization and dissipation. However, all too often …

Light-emitting diodes (LEDs) are widely used in horticultural facilities in recent years.
However, the influence of light quality on photosynthesis still calls for further exploration …

Photoreceptor-mediated light signaling plays a critical role in plant growth, development,
and stress responses but its contribution to the spatial regulation of photoinhibition and …

Plants grow in constantly changing environments, including highly variable light intensities.
Sunlight provides the energy that drives photosynthesis and is thus of the utmost importance …

Light is essential for photosynthesis, but the amounts of light that exceed an organism's
assimilation capacity can result in oxidative stress and even cell death. Plants and …

Abstract Ultraviolet B (UV-B) radiation has been previously reported to induce changes in
secondary metabolites such as phenolic compounds by improving, in particularly, the …

Plants experience low ambient temperature and low red to far-red ratios (LR/FR) of light due
to vegetative shading and longer twilight durations in cool seasons. Low temperature induce …

Light is a key environmental variable regulating the growth and development of vegetables
in controlled environment agriculture, and the red–blue ratio (R: B) plays an important role in …
