ATP‐induced photochemical quenching of variable chlorophyll fluorescence [PDF]

FEBS Letters, 1987
ATP induces rapid quenching of fluorescence yield in light‐activated class D chloroplasts, distinguishable from the slower quenching caused by protein phosphorylation. The mechanism of the rapid quenching is shown to be photochemical, by application of the saturation pulse method with a modulated measuring system [(1986) Photosynth. Res.

Photochemical and photoelectrochemical quenching of chlorophyll fluorescence in photosystem II

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2009
This paper deals with kinetics and properties of variable fluorescence in leaves and thylakoids upon excitation with low intensity multi-turnover actinic light pulses corresponding with an excitation rate of about 10 Hz. These show a relatively small and amply documented rise in the sub-s time range towards the plateau level F(pl) followed by a delayed

A kinetic model of non-photochemical quenching in cyanobacteria

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2011
High light poses a threat to oxygenic photosynthetic organisms. Similar to eukaryotes, cyanobacteria evolved a photoprotective mechanism, non-photochemical quenching (NPQ), which dissipates excess absorbed energy as heat. An orange carotenoid protein (OCP) has been implicated as a blue-green light sensor that induces NPQ in cyanobacteria. Discovered in

Photoinhibition, carotenoid composition and the co-regulation of photochemical and non-photochemical quenching in neotropical savanna trees [PDF]

Tree Physiology, 2007
Plants in the neotropical savannas of central Brazil are exposed to high irradiances, high air temperatures and low relative humidities. These conditions impose a selection pressure on plants for strong stomatal regulation of transpiration to maintain water balance.

Resistance of Primary Photosynthesis to Photoinhibition in Antarctic Lichen Xanthoria elegans: Photoprotective Mechanisms Activated during a Short Period of High Light Stress

Plants, 2023
The Antarctic lichen, Xanthoria elegans, in its hydrated state has several physiological mechanisms to cope with high light effects on the photosynthetic processes of its photobionts.

Transcriptome and physiology analysis reveal key players of the shade-tolerant species Panax notoginseng in photosynthetic performance under both high and low light regimes

Journal of Plant Interactions, 2022
The present study aimed to understand the molecular mechanism underlying the light-induced depression of photosynthetic capacity in a typically shade-tolerant species Panax notoginseng grown under different light intensities.

Seasonality and Small Spatial-Scale Variation of Chlorophyll a Fluorescence in Bryophyte Syntrichia ruralis [Hedw.] in Semi-Arid Sandy Grassland, Hungary

Plants, 2020
Bryophytes face challenges due to global climate change which is leading to in-depth research in monitoring and studying their photosynthetic activity. The aim of this preliminary experiment was to study the seasonal variation trend in the chlorophyll a ...
