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 ...

Wheat truncated hemoglobin interacts with photosystem I PSK-I subunit and photosystem II subunit PsbS1 [PDF]

Biologia Plantarum, 2013
Recently, the truncated hemoglobin gene (trHb) was discovered in plant species, however, its role has not yet been determined. In this study, the gene expression of wheat trHb (TatrHb) was analyzed under various biotic and abiotic stresses.

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.

Energy transfer from phycobilisomes to photosystem I at room temperature [PDF]

Frontiers in Plant Science, 2023
The phycobilisomes function as the primary light-harvesting antennae in cyanobacteria and red algae, effectively harvesting and transferring excitation energy to both photosystems.

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.
