Mechanisms underpinning natural variation in non-photochemical quenching kinetics. [PDF]
Biochem Soc TransPlants use light as an energy source to reduce carbon dioxide into carbohydrates during photosynthesis. However, when the incident light exceeds the photosynthesis rate, the excess energy must be dispersed, or it can result in the unregulated formation of harmful reactive oxygen species, especially in plants exposed to very high light or abiotic stress

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.

Non-Photochemical Quenching. A Response to Excess Light Energy [PDF]
Plant Physiology, 2001 Plants and algae have a love/hate relationship with light. As oxygenic photoautotrophic organisms, they require light for life; however, too much light can lead to increased production of damaging reactive oxygen species as byproducts of photosynthesis.

The state of plant photosystem II reaction centres affects the rate of non-photochemical quenching. [PDF]
Nat PlantsPlants employ non-photochemical quenching (NPQ) to protect their photosynthetic apparatus from photodamage. The response latency of NPQ following changes in light intensity is thought to significantly decrease photosynthetic efficiency. The amount of NPQ

Investigating non-photochemical quenching in model membranes [PDF]
, 2021 Non-photochemical quenching of chlorophyll fluorescence (NPQ) is a photoprotective process that harmlessly dissipates excess excitation energy as heat.

Journal of Oasis Agriculture and Sustainable Development, 2023 Sulla carnosa Desf. plants were subjected to 0, 100, 200, and 300 mM NaCl for 40 days. Leaf and stem growth as well as root and leaf water contents were not affected even at 300 mM NaCl, confirming the halophytic nature of this species.

Analysis of initial chlorophyll fluorescence induction kinetics in chloroplasts in terms of rate constants of donor side quenching release and electron trapping in photosystem II [PDF]
, 2008 The fluorescence induction F(t) of dark-adapted chloroplasts has been studied in multi-turnover 1 s light flashes (MTFs). A theoretical expression for the initial fluorescence rise is derived from a set of rate equations that describes the sequence of ...

Light-induced Dissociation of an Antenna Hetero-oligomer Is Needed for Non-photochemical Quenching Induction [PDF]
, 2009 PsbS plays a major role in activating the photoprotection mechanism known as "non-photochemical quenching," which dissipates chlorophyll excited states exceeding the capacity for photosynthetic electron transport.
