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.

Phosphorylation of light-harvesting complex II controls excitation energy spillover between photosystems

The paper shows phosphorylated LHCIIs in green algae mediate excitation energy spillover from PSII to PSI, enhancing photosynthetic adaptation under variable light conditions.

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.

Environmental filtering in marine fish communities is weakened during severe hypoxia season

This study shows that environmental filtering in marine fish communities weakens during severe hypoxia, despite increased environmental severity and heterogeneity.

Development of a humanized mouse model to analyze antibodies specific for human leukocyte antigen (HLA)

This paper develops a humanized mouse model to study anti-HLA antibody production, finding that allo-specific antibodies are suppressed while non-allo-specific antibodies are detectable.
