Quality control of photosystem II: lipid peroxidation accelerates photoinhibition under excessive illumination. [PDF]

PLoS ONE, 2012
Environmental stresses lower the efficiency of photosynthesis and sometimes cause irreversible damage to plant functions. When spinach thylakoids and Photosystem II membranes were illuminated with excessive visible light (100-1,000 µmol photons m(-1) s ...

Photosynthetic Light Harvesting and Thylakoid Organization in a CRISPR/Cas9 Arabidopsis Thaliana LHCB1 Knockout Mutant

Frontiers in Plant Science, 2022
Light absorbed by chlorophylls of Photosystems II and I drives oxygenic photosynthesis. Light-harvesting complexes increase the absorption cross-section of these photosystems.

Dynamics of photosystem II: a proteomic approach to thylakoid protein complexes [PDF]

Journal of Experimental Botany, 2004
Oxygenic photosynthesis produces various radicals and active oxygen species with harmful effects on photosystem II (PSII). Such photodamage occurs at all light intensities. Damaged PSII centres, however, do not usually accumulate in the thylakoid membrane due to a rapid and efficient repair mechanism.

High-resolution model of Arabidopsis Photosystem II reveals the structural consequences of digitonin-extraction

Scientific Reports, 2021
In higher plants, the photosynthetic process is performed and regulated by Photosystem II (PSII). Arabidopsis thaliana was the first higher plant with a fully sequenced genome, conferring it the status of a model organism; nonetheless, a high-resolution ...

Truncated recombinant light harvesting complex II proteins are substrates for a protein kinase associated with photosystem II core complexes [PDF]

FEBS Letters, 1998
Previous studies directed towards understanding phosphorylation of the chlorophyll a/b binding proteins comprising light harvesting complex II (LHC II) have concentrated on a single phosphorylation site located close to the N‐terminus of the mature proteins.

Rapeseed (Brassica napus) Mitogen-Activated Protein Kinase 1 Enhances Shading Tolerance by Regulating the Photosynthesis Capability of Photosystem II

Frontiers in Plant Science, 2022
Rapeseed (Brassica napus) is the third-largest source of vegetable oil in the world with an edible, medicinal, and ornamental value. However, insufficient light or high planting density directly affects its growth, development, yield, and quality ...

A novel chlorophyll protein complex in the repair cycle of photosystem II [PDF]

Proceedings of the National Academy of Sciences, 2019
In oxygenic photosynthetic organisms, photosystem II (PSII) is a unique membrane protein complex that catalyzes light-driven oxidation of water. PSII undergoes frequent damage due to its demanding photochemistry. It must undergo a repair and reassembly process following photodamage, many facets of which remain unknown.

Photosynthetic Production of Molecular Oxygen by Water Oxidation

Oxygen, 2022
This review deals with the production of oxygen by photo-oxidation of water, which is a topic fitting a journal devoted to oxygen. Most of the present biosphere, including mankind, depends on oxygen. Elucidating the mechanism is of importance for solving
