Iron rescues glucose-mediated photosynthesis repression during lipid accumulation in the green alga Chromochloris zofingiensis

Cysteine: an ancestral Cu binding ligand in green algae?

The paper shows that cysteine is an ancestral Cu(I) ligand in Chlamydomonas reinhardtii, as Zn deficiency disrupts Cu homeostasis and increases cysteine levels, which co-localize with Cu in acidocalcisomes.

Single cell carbon and nitrogen incorporation and remineralization profiles are uncoupled from phylogenetic groupings of diatom-associated bacteria

The paper quantifies single-cell carbon and nitrogen exchange between diatoms and bacteria, finding functional categories not linked to phylogeny.

Structure Of Eukaryotic Type III Glutamine Synthetase Lacking Ring-Ring Quaternary Contacts

The paper reports the cryo-EM structure of eukaryotic GSIII from Ostreococcus tauri and shows it forms a single hexameric ring, differing from other GS classes.

Genome-resolved metaproteomics decodes the microbial and viral contributions to coupled carbon and nitrogen cycling in river sediments

The paper integrates metagenomic, metaproteomic, and metabolomic data from river sediments to uncover microbial and viral roles in carbon and nitrogen cycling, creating a genomic resource called HUM-V.
