Integrated cellular and molecular responses to uranium chemotoxicity in the metal-tolerant microalga Coelastrella sp. PCV

This study investigates uranium toxicity in the metal-tolerant microalga Coelastrella sp. PCV using multi-omics and imaging, revealing sequestration mechanisms and gene network rewiring.

Identification of uranyl-binding proteins in Arabidopsis thaliana cells exposed to uranium: Insights from a metalloproteomic analysis and characterization of Glycine-Rich RNA-binding Protein 7 (GRP7)

This study identifies 57 uranyl-binding proteins in Arabidopsis thaliana cells, with GRP7 showing specific U(VI) binding and interference with RNA binding, suggesting a role in uranium toxicity.

GCS-H2 is essential for growth as it acts as the main relay for mitochondrial lipoylation in heterotrophic tissues of Arabidopsis thaliana

The absence of GCS-H2, an isoform of H-protein found in heterotrophic tissue, impedes the cell cycle, and drastically affects plant growth as it acts as the main relay for mitochondrial lipoylation.

Dynamics of the membrane- and cell wall-associated proteome of Arabidopsis thaliana roots in response to uranium stress

This study identifies 458 differentially accumulated proteins in Arabidopsis roots under uranium stress, revealing changes in cell wall dynamics, metal transport, and stress responses.
