Magnetic organelle gene clusters enable bacterial growth and ATP homeostasis under oxidizing conditions

This study shows that gene clusters for magnetite formation in bacteria confer resistance to hydrogen peroxide, supporting an early origin of magnetotactic bacteria before Earth's oxygenation.

Genome-wide chromatin reset at the onset of leg regeneration in pancrustaceans

The paper investigates chromatin state reorganization during leg regeneration in pancrustaceans, finding a conserved sequence of chromatin resetting and pioneer factor activation across species.

Rad55-Rad57 and Srs2 regulate homology search onset, coordination, reach and inactivation

This study investigates how Rad55-Rad57 and Srs2 regulate homology search in yeast by controlling Rad51-ssDNA filament stability and coordination.

Condensin loop extrusion properties, roadblocks, and role in homology search in S. cerevisiae

The paper identifies condensin-dependent loop extrusion and roadblocks in S. cerevisiae, showing their role in homology search during DNA repair.

Trans-acting mutations reveal non-nuclear modulators of both intrinsic and extrinsic gene expression noise in a eukaryote.

The paper identifies trans-acting mutations in yeast that modulate gene expression noise in both intrinsic and extrinsic ways, revealing non-nuclear factors influencing nuclear gene expression.

Characterizing drug activity with sensitive interactomes in human living cells

The paper introduces a method to identify drug-sensitive protein-protein interactions in live cells using ERK1 as a case study, showing how inhibitory molecules affect these interactions.

Mechanism of homology search expansion during recombinational DNA break repair

This paper investigates the mechanism of homology search expansion during DNA break repair, revealing how chromatin structure, NPF stiffening, and resection drive genome-wide search.

Cohesin regulates homology search during recombinational DNA repair

This study shows cohesin promotes cis dsDNA over-sampling during homology search in yeast by blocking cohesin progression and enabling loop expansion-coupled scanning.
