Electron transfer in photosystem I
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2001 This mini-review focuses on recent experimental results and questions, which came up since the last more comprehensive reviews on the subject. We include a brief discussion of the different techniques used for time-resolved studies of electron transfer in photosystem I (PS I) and relate the kinetic results to new structural data of the PS I reaction ...

Vibrational spectroscopy of photosystem I
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015 Fourier transform infrared difference spectroscopy (FTIR DS) has been widely used to study the structural details of electron transfer cofactors (and their binding sites) in many types of photosynthetic protein complexes. This review focuses in particular on work that has been done to investigate the A₁cofactor in photosystem I photosynthetic reaction ...

Structure of the red-shifted Fittonia albivenis photosystem I [PDF]
Nature CommunicationsPhotosystem 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 BiologyPhotosynthetic 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.

Molecular diversity and evolution of far-red light-acclimated photosystem I
Frontiers in Plant Science, 2023 The need to acclimate to different environmental conditions is central to the evolution of cyanobacteria. Far-red light (FRL) photoacclimation, or FaRLiP, is an acclimation mechanism that enables certain cyanobacteria to use FRL to drive photosynthesis ...

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 ...
