Chlorophyll a fluorescence (ChlF) has been used for decades to study the organization,
functioning, and physiology of photosynthesis at the leaf and subcellular levels. ChlF is now …

▪ Abstract The involvement of excited and highly reactive intermediates in oxygenic
photosynthesis poses unique problems for algae and plants in terms of potential oxidative …

The photosynthetic electron transport chain consists of photosystem II, the cytochrome b6f
complex, photosystem I, and the free electron carriers plastoquinone and plastocyanin. Light …

Oxygenic photosynthetic organisms experience strong fluctuations in light intensity in their
natural terrestrial and aquatic growth environments. Recent studies with both plants and …

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

Illumination changes elicit modifications of thylakoid proteins and reorganization of the
photosynthetic machinery. This involves, in the short term, phosphorylation of photosystem II …

Highly flexible regulation of photosynthetic light reactions in plant chloroplasts is a
prerequisite to provide sufficient energy flow to downstream metabolism and plant growth, to …

LHCII, the most abundant membrane protein on earth, is the major light-harvesting complex
of plants. It is generally accepted that LHCII is associated with Photosystem II and only as a …

The ability of plants to adapt to changing light conditions depends on a protein kinase
network in the chloroplast that leads to the reversible phosphorylation of key proteins in the …

Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for
water splitting, oxygen evolution, and plastoquinone reduction. Components of PSII can be …
