Photoinhibition and protection of photosystem I. [PDF]

Plant Cell Physiol, 2007
Abstract Over 30 years ago, when we first reported the selective photoinhibition of photosystem I (PSI) in chilling-sensitive plants at chilling temperatures, the inhibition tended to be regarded as a specific phenomenon observed only under unusual conditions.

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.

The Plasticity of Photosystem I

Plant and Cell Physiology, 2021
Abstract Most of life’s energy comes from sunlight, and thus, photosynthesis underpins the survival of virtually all life forms. The light-driven electron transfer at photosystem I (PSI) is certainly the most important generator of reducing power at the cellular level and thereby largely determines the global amount of enthalpy in living

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.

Polymer-Modified Single-Walled Carbon Nanotubes Affect Photosystem II Photochemistry, Intersystem Electron Transport Carriers and Photosystem I End Acceptors in Pea Plants

Molecules, 2021
Single-walled carbon nanotubes (SWCNT) have recently been attracting the attention of plant biologists as a prospective tool for modulation of photosynthesis in higher plants.

Special issue in honour of Prof. Reto J. Strasser - Photosynthetic efficiency of two Platanus orientalis L. ecotypes exposed to moderately high temperature - JIP-test analysis

Photosynthetica, 2020
Plane (Platanus orientalis) is a popular park tree in Europe but is almost extinct in natural ecosystems, because of climate changes. In our study, two ecotypes of plane tree (Bulgarian and Italian) were submitted to moderately elevated temperature that ...
