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.

RpaA regulates the accumulation of monomeric photosystem I and PsbA under high light conditions in Synechocystis sp. PCC 6803. [PDF]

PLoS ONE, 2012
The response regulator RpaA was examined by targeted mutagenesis under high light conditions in Synechocystis sp. PCC 6803. A significant reduction in chlorophyll fluorescence from photosystem I at 77 K was observed in the RpaA mutant cells under high ...

The cryo-EM structure of Photosystem I from Chromera velia with a bound superoxide dismutase heterodimer [PDF]

Nature Communications
Photosystem I is a key component of the solar energy conversion machinery in oxygenic photosynthesis, and its core, where photochemistry occurs, is highly conserved.

Shining light on dinoflagellate photosystem I [PDF]

Nature Communications
Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp.

Structure of the red-shifted Fittonia albivenis photosystem I [PDF]

Nature Communications
Photosystem I (PSI) from Fittonia albivenis, an Acanthaceae ornamental plant, is notable among green plants for its red-shifted emission spectrum. Here, we solved the structure of a PSI–light harvesting complex I (LHCI) supercomplex from F.

Growth phase-dependent reorganization of cryptophyte photosystem I antennae [PDF]

Communications Biology
Photosynthetic cryptophytes are eukaryotic algae that utilize membrane-embedded chlorophyll a/c binding proteins (CACs) and lumen-localized phycobiliproteins (PBPs) as their light-harvesting antennae.

Photosystem stoichiometry adjustment is a photoreceptor-mediated process in Arabidopsis

Scientific Reports, 2022
Plant growth under spectrally-enriched low light conditions leads to adjustment in the relative abundance of the two photosystems in an acclimatory response known as photosystem stoichiometry adjustment.

Special issue in honour of Prof. Reto J. Strasser - Influence of Cuscuta campestris Yunck. on the photosynthetic activity of Ipomoea tricolor Cav. - in vivo chlorophyll a fluorescence assessment

Photosynthetica, 2020
Cuscuta campestris Yunck. is a parasitic plant, acquiring nutrients from the hosts. Although a generalist, its hosts differ in their susceptibility. Ipomoea tricolor Cav. is a semi-compatible host - C.
