The involvement of photosystem II-generated H2O2 in photoinhibition

, 1991
The involvement of H2O2 generated by photosystem II (PSII) in the process of photoinhibition of thylakoids with a functional oxygen-evolving complex (OEC) was investigated.

Photoinhibition and recovery after selective short-term exposure to solar radiation of five chlorophyll c-containing marine microalgae

Ciencias Marinas, 2002
The differential sensitivity of five chlorophyll c-containing marine microalgae to different components of solar radiation, e.g. photosynthetic active radiation (PAR), ultraviolet-A (UV-A) and ultraviolet-B (UV-B), was investigated in an exclusion ...

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

Effect of solar and artificial UV radiation on photosynthetic performance and carbonic anhydrase activity in intertidal macroalgae from southern Spain

Ciencias Marinas, 2009
The effect of UV radiation on photosynthetic rate and carbon uptake, estimated as carbonic anhydrase activity, was studied by incubating intertidal algae, Fucus spiralis (Phaeophyta) and Ulva olivascens (Chlorophyta), under both artificial and solar ...

Effects of dopamine on reducing salt stress damage in pepper (Capsicum annuum L.) at morphological, physiological, biochemical, and molecular levels

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Salt stress causes oxidative and osmotic stress, resulting in decreased nutrient uptake, plant growth, and photosynthetic rate. This study suggests that foliar application of dopamine can reduce salinity‐induced oxidative damage in pepper plants by altering antioxidant activity, biochemical, and molecular responses.

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

New Phytologist, Volume 251, Issue 1, Page 372-383, July 2026.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

Potential impact of photoinhibition on microphytobenthic primary production on a large intertidal mudflat

, 2021
Microphytobenthos (MPB) are a key primary producer of intertidal mudflats. MPB face strong variability in incident irradiance during low tides. Despite photoprotection and photoacclimation, such variations can translate into photoinhibition of MPB cells.

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Photoinhibition Superresolution Lithography

, 2014
While the prospect of nanoscale manufacturing has generated tremendous excitement, arbitrary patterning at nanometer length scales cannot be brought about with current photolithography -- the technology that for decades has driven electronics ...
