This paper shows BR-bodies in Brucella regulate RNA stability and virulence by linking phase separation to stress resistance and intracellular fitness.

This study characterizes Caulobacter sp. RL271, a hub taxon in the soybean root endosphere, revealing its unique biofilm formation and riboflavin-mediated mutualism with Bradyrhizobium.

The paper identifies 200 genes affecting Myxococcus xanthus developmental fate in mixed populations through barcoded transposon mutant analysis.

This study uses a CRISPR screen to identify host genes critical for early Brucella infection in human macrophage-like cells, revealing shared and pathogen-specific dependencies.

This paper identifies and characterizes a new Caulobacter phage, Circe, showing it uses smooth lipopolysaccharide as a receptor for infection.

This paper identifies the hiuABC operon in Caulobacter crescentus as essential for utilizing xenosiderophores, with specific roles for each gene in iron acquisition from hydroxamate-family siderophores.

This study identifies non-redundant roles of ClsA and ClsB in shaping lipid composition and stress resilience in Bacteroides fragilis.

This study identifies dihydropyridines as inhibitors of Brucella ovis growth and shows that pseudogenes like bepE can confer stress resistance through functional restoration.

This study identifies a gene pair essential for Caulobacter iron homeostasis under EDTA stress and shows its conservation in Proteobacteria.

This study shows that Bacteroides fragilis from UC patients promotes colitis in genetically susceptible mice, suggesting a role for pathobionts in IBD.
