This study identifies multiple non-redundant functions of lipopolysaccharide (LPS) in Gram-negative bacteria, showing it is essential for envelope mechanics, membrane biogenesis, and efflux pump activity.

This study shows that outer membrane fluidity and mechanics in Gram-negative bacteria can be independently controlled by altering lipid composition and crosslinking.

This study uses phage-based manipulation to reveal ecological interactions in gut microbiomes by targeting Escherichia fergusonii and analyzing its role in community dynamics.

This study shows that MreB couples the cell wall to the cytoplasmic membrane in E. coli, increasing resistance to bending and preventing membrane detachment under stress.

The paper uses double-CRISPRi to systematically analyze genetic interactions in Bacillus subtilis, identifying over 1000 interactions and revealing roles of paralogous genes in cell division.
