The paper demonstrates the use of plasmid entry exclusion to selectively deliver DNA to specific bacterial recipients in mixed communities.

This study shows Type I partition proteins enhance bacterial conjugation by activating conjugation genes and binding oriT regions, revealing a link between plasmid partitioning and dissemination.

This study constructs chimeric T4SSs by swapping subunits between distantly-related F plasmids, revealing structural and functional flexibility in type IV secretion systems.

This study demonstrates the use of ligand-displaying E. coli cells and minicells to deliver toxic payloads via T4SSs, enhancing conjugative transfer and killing specific bacterial targets.
