Sunlight damages photosynthetic machinery, primarily photosystem II (PSII), and causes
photoinhibition that can limit plant photosynthetic activity, growth and productivity. The extent …

Photosystem (PS) II is a multisubunit thylakoid membrane pigment–protein complex
responsible for light-driven oxidation of water and reduction of plastoquinone. Currently …

Photosystem II (PSII) is an integral-membrane, multisubunit complex that initiates electron
flow in oxygenic photosynthesis. The biogenesis of this complex machine involves the …

Inhibition of the activity of photosystem II (PSII) under strong light is referred to as
photoinhibition. This phenomenon is due to the imbalance between the rate of …

Abstract Background Photosystem II (PSII) is the light-driven water: plastoquinone
oxidoreductase of oxygenic photosynthesis and is found in the thylakoid membrane of …

Oxygenic photosynthesis produces various radicals and active oxygen species with harmful
effects on photosystem II (PSII). Such photodamage occurs at all light intensities. Damaged …

Proteolysis is essential for many aspects of plant physiology and development. It is
responsible for cellular housekeeping and the stress response by removing …

The ability of photosystem (PS) II to catalyze the light-driven oxidation of water comes along
with its vulnerability to oxidative damage, in particular of the D1 core subunit …

The Photosystem (PS) II of cyanobacteria, green algae and higher plants is prone to light-
induced inactivation, the D1 protein being the primary target of such damage. As a …

Singlet oxygen, generated during photosynthesis, is a strong oxidant that can, potentially,
damage various molecules of biological importance. We investigated the effects in vivo of …
