Identification and Roles of Photosystem II Assembly, Stability, and Repair Factors in Arabidopsis

Frontiers 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.

Advances in the Understanding of the Lifecycle of Photosystem II

Microorganisms, 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.

Photoinactivation of Photosystem II in Prochlorococcus and Synechococcus. [PDF]

PLoS ONE, 2017
The marine picocyanobacteria Synechococcus and Prochlorococcus numerically dominate open ocean phytoplankton. Although evolutionarily related they are ecologically distinct, with different strategies to harvest, manage and exploit light.

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.

The effect of nicosulfuron and bentazon on photosynthetic performance of common cocklebur (Xanthium strumarium L.)

Environmental and Sustainability Indicators, 2020
In order to evaluate the effects of bentazon and nicosulfuron on the photosynthetic apparatus of X. strumarium in greenhouse condition, chlorophyll a fluorescence (ChlF) method was studied at 1, 2, 3, and 4 days after herbicide treatment (DAHT). Bentazon

Photophysiological and photosynthetic complex changes during iron starvation in Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942. [PDF]

PLoS ONE, 2013
Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

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 ...

Impact of energy limitations on function and resilience in long-wavelength Photosystem II

eLife, 2022
Photosystem II (PSII) uses the energy from red light to split water and reduce quinone, an energy-demanding process based on chlorophyll a (Chl-a) photochemistry. Two types of cyanobacterial PSII can use chlorophyll d (Chl-d) and chlorophyll f (Chl-f) to
