Photoprotection of photosystem II (PSII) is essential to avoid the light-induced damage of the
photosynthetic apparatus due to the formation of reactive oxygen species (= photo-oxidative …

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 …

Figures showing species and properties relevant to non-photochemical quenching
studies.(a) Filamentous planktonic cyanobacteria Dolichospermum crassum and D. flos …

All photosynthetic organisms need to regulate light harvesting for photoprotection. Three
types of flexible non-photochemical quenching (NPQ) mechanisms have been characterized …

Plants and algae often absorb too much light—more than they can actually use in
photosynthesis. To prevent photo-oxidative damage and to acclimate to changes in their …

Photosynthetic pigment composition has been a major study target in plant ecophysiology
during the last three decades. Although more than 2000 papers have been published, a …

Light is necessary for photosynthesis, but its absorption by pigment molecules such as
chlorophyll can cause severe oxidative damage and result in cell death. The excess …

Oxygenic photosynthesis is indispensable both for the development and maintenance of life
on earth by converting light energy into chemical energy and by producing molecular …

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 …

In photosynthetic organisms, feedback dissipation of excess absorbed light energy balances
harvesting of light with metabolic energy consumption. This mechanism prevents …
