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

open access: yesProceedings of the National Academy of Sciences, 2019
Significance Photosystem II (PSII) converts sunlight into chemical energy, powering nearly all life on Earth. The efficiency of this process is maximized under various environmental conditions by a frequent repair and reassembly cycle that follows ...

Advances in the Understanding of the Lifecycle of Photosystem II

open access: yesMicroorganisms, 2022
Photosystem II is a light-driven water-plastoquinone oxidoreductase present in cyanobacteria, algae and plants. It produces molecular oxygen and protons to drive ATP synthesis, fueling life on Earth.

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

open access: yesScientific 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 ...

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

open access: yesJournal 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.

Identification and roles of Photosystem II assembly, stability, and repair factors in Arabidopsis

open access: yesFrontiers in Plant Science, 2016
Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction.

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

open access: yesPLoS 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

open access: yesFrontiers 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.

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

open access: yesFrontiers 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 ...

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

open access: yesFEBS 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.
