Elevated Levels of Specific Carotenoids During Acclimation to Strong Light Protect the Repair of Photosystem II in Synechocystis sp. PCC 6803

Frontiers in Plant Science, 2020
The tolerance of photosynthesis to strong light increases in photosynthetic organisms during acclimation to strong light. We investigated the role of carotenoids in the protection of photosystem II (PSII) from photoinhibition after acclimation to strong ...

High light stress under phosphorus limitation in summer may accelerate diatom shift from Skeletonema to Chaetoceros in an oligotrophic coastal area of Japan

Frontiers in Marine Science, 2023
In the Seto Inland Sea, the largest semi-enclosed sea in Japan, the most dominant diatom in the past, Skeletonema spp., has been replaced by another diatom Chaetoceros spp.

Indication of Light Stress in Ficus elastica Using Hyperspectral Imaging

AgriEngineering, 2023
Hyperspectral imaging techniques are widely used to remotely assess the vegetation and physiological condition of plants. Usually, such studies are carried out without taking into account the light history of the objects (for example, direct sunlight or ...

The photoinhibition of malate dehydrogenase [PDF]

FEBS Letters, 1972
Recently several enzymes which require FMN as a cofactor have been shown to be inhibited by blue light in the presence of added FMN [l-3] . Photoinactivation of the enzyme protein occurred via the formation of triplet FMN. The present paper reports, for the first time, an FMN-mediated photoinhibition of NAD-malate dehydrogenase, a key enzyme of the ...

Off-Target Influences of Arch-Mediated Axon Terminal Inhibition on Network Activity and Behavior

Frontiers in Neural Circuits, 2020
Archaerhodopsin (ArchT)-mediated photoinhibition of axon terminals is commonly used to test the involvement of specific long-range neural projections in behavior.

Photorespiration Alleviates Photoinhibition of Photosystem I under Fluctuating Light in Tomato

Plants, 2022
Fluctuating light (FL) is a typical natural light stress that can cause photodamage to photosystem I (PSI). However, the effect of growth light on FL-induced PSI photoinhibition remains controversial.

Photoinhibition of photosystem I [PDF]

Physiologia Plantarum, 2010
The photoinhibition of Photosystem I (PSI) drew less attention compared with that of Photosystem II (PSII). This could be ascribed to several reasons, e.g. limited combinations of plant species and environmental conditions that cause PSI photoinhibition, the non‐regulatory aspect of PSI photoinhibition, and methodological difficulty to determine the ...

Single-cell microfluidics in combination with chlorophyll a fluorescence measurements to assess the lifetime of the Chlamydomonas PSBO protein

Photosynthetica, 2023
PSBO is an essential subunit of the oxygen-evolving complex and we recently demonstrated that its lifetime depends on environmental conditions in Chlamydomonas reinhardtii.

Moderate Photoinhibition of Photosystem II Significantly Affects Linear Electron Flow in the Shade-Demanding Plant Panax notoginseng

Frontiers in Plant Science, 2018
Although photoinhibition of photosystem II (PSII) frequently occurs under natural growing conditions, knowledge about the effect of moderate photoinhibition on linear electron flow (LEF) remains controversial.

Photoinhibition of Photosystem I Provides Oxidative Protection During Imbalanced Photosynthetic Electron Transport in Arabidopsis thaliana

Frontiers in Plant Science, 2019
Photosynthesis involves the conversion of sunlight energy into stored chemical energy, which is achieved through electron transport along a series of redox reactions.
