Contributions of PD1 and PD2 to the difference spectrum in the Soret region in Photosystem II

The paper investigates the contribution of PD1 and PD2 to the difference spectrum in the Soret region of PSII by analyzing mutants and comparing their spectra to wild-type strains.

Structure of PSI-LHCI from Cyanidium caldarium provides evolutionary insights into conservation and diversity of red-lineage LHCs

The paper determines the structure of PSI-LHCI from Cyanidium caldarium and investigates its evolutionary relationships with other red-lineage LHCs.

Structure of a monomeric photosystem I core associated with iron-stress-induced-A proteins from Anabaena sp. PCC 7120

The paper determines the structure of a monomeric photosystem I core complex with IsiA proteins from Anabaena sp. PCC 7120 under iron deficiency, revealing their role in inhibiting PSI oligomerization.

Absorption changes in Photosystem II in the Soret band region upon the formation of the chlorophyll cation radical +

The paper measures absorption changes in Photosystem II's Soret band region caused by the chlorophyll cation radical [PD1PD2]+, showing a 'W-shaped' signal dependent on TyrD and its H-bonding environment.

Structural insights into an evolutionary turning-point of photosystem I from prokaryotes to eukaryotes

The paper presents a cryo-EM structure of tetrameric PSI from Cyanophora paradoxa, revealing structural differences from cyanobacterial PSI that suggest evolutionary changes in PSI organization.

Structural basis for the absence of low-energy chlorophylls responsible for photoprotection from a primitive cyanobacterial PSI

The paper solves the structure of a cyanobacterial PSI lacking low-energy chlorophylls, revealing their absence and functional roles in photoprotection and evolution.

Molecular phylogeny of fucoxanthin-chlorophyll a/c proteins from Chaetoceros gracilis and Lhcq/Lhcf diversity

The paper identifies and classifies 46 FCPs in C. gracilis into five subfamilies, revealing insights into light-harvesting system diversification in red algae.
