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 …

In their natural environment plants and algae are exposed to rapidly changing light
conditions and light intensities. Illumination with high light intensities has the potential to …

The xanthophyll cycle represents one of the important photoprotection mechanisms in plant
cells. In the present review, we summarize current knowledge about the violaxanthin cycle of …

Salicylic acid (SA), an essential plant hormone, has received much attention due to its role in
modulating the adverse effects of biotic and abiotic stresses, acting as an antioxidant and …

In order to maximize their use of light energy in photosynthesis, plants have molecules that
act as light-harvesting antennae, which collect light quanta and deliver them to the reaction …

Marine primary productivity is iron (Fe)-limited in vast regions of the contemporary oceans,
most notably the high nutrient low chlorophyll (HNLC) regions. Diatoms often form large …

Abstract Photoinhibition of Photosystem II (PSII) is the light-induced loss of PSII electron-
transfer activity. Although photoinhibition has been studied for a long time, there is no …

The ch1 mutant of Arabidopsis (Arabidopsis thaliana) lacks chlorophyll (Chl) b. Leaves of
this mutant are devoid of photosystem II (PSII) Chl-protein antenna complexes and have a …

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 …

Highly flexible regulation of photosynthetic light reactions in plant chloroplasts is a
prerequisite to provide sufficient energy flow to downstream metabolism and plant growth, to …
