NTRC Effects on Non-Photochemical Quenching Depends on PGR5. [PDF]
Antioxidants (Basel), 2021 Non-photochemical quenching (NPQ) protects plants from the detrimental effects of excess light. NPQ is rapidly induced by the trans-thylakoid proton gradient during photosynthesis, which in turn requires PGR5/PGRL1-dependent cyclic electron flow (CEF ...

How much heat does non-photochemical quenching produce? [PDF]
Front Plant SciNon-photochemical quenching (NPQ) is a protective mechanism used by plants to safely dissipate excess absorbed light energy as heat, minimizing photo-oxidative damage. Although the importance of NPQ as a safety valve for photosynthesis is well-known, the

Light Quality-Dependent Regulation of Non-Photochemical Quenching in Tomato Plants. [PDF]
Biology (Basel), 2021 Photosynthetic pigments of plants capture light as a source of energy for photosynthesis. However, the amount of energy absorbed often exceeds its utilization, thus causing damage to the photosynthetic apparatus.

Temperature mapping of non-photochemical quenching in Chlorella vulgaris. [PDF]
Photosynth Res, 2023 AbstractLight intensity and temperature independently impact all parts of the photosynthetic machinery in plants and algae. Yet to date, the vast majority of pulse amplitude modulated (PAM) chlorophyll a fluorescence measurements have been performed at well-defined light intensities, but rarely at well-defined temperatures.

Non-Photochemical Quenching under Drought and Fluctuating Light. [PDF]
Int J Mol Sci, 2022 Plants grow in a variable environment in regard to soil water and light driving photochemical reactions. Light energy exceeding plant capability to use it for photochemical reactions must be dissipated by processes of non-photochemical quenching (NPQ).

Non-Photochemical Quenching: From Light Perception to Photoprotective Gene Expression. [PDF]
Int J Mol Sci, 2022 Light is essential for photosynthesis but light levels that exceed an organism’s assimilation capacity can cause serious damage or even cell death. Plants and microalgae have developed photoprotective mechanisms collectively referred to as non-photochemical quenching to minimize such potential damage.

Melanisation in Boreal Lichens Is Accompanied by Variable Changes in Non-Photochemical Quenching. [PDF]
Plants (Basel), 2022 Lichens often grow in microhabitats where they absorb more light than they can use for fixing carbon, and this excess energy can cause the formation of harmful reactive oxygen species (ROS).

Non-photochemical quenching capacity in Arabidopsis thaliana affects herbivore behaviour. [PDF]
PLoS ONE, 2013 Under natural conditions, plants have to cope with numerous stresses, including light-stress and herbivory. This raises intriguing questions regarding possible trade-offs between stress defences and growth.

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

Disentangling the sites of non-photochemical quenching in vascular plants. [PDF]
Nat Plants, 2019 In nature, plants experience large fluctuations in light intensity and they need to balance the absorption and utilization of this energy appropriately. Non-photochemical quenching (NPQ) is a rapidly switchable mechanism that protects plants from photodamage caused by high light exposure by dissipating the excess absorbed energy as heat.
