Genomics and genetics were used to identify specialized metabolites employed by Pseudomonas bacteria to suppress the growth of potato pathogens, which revealed a key role for cyclic lipopeptides.
Analysis of the global genetic requirements and gene expression changes in E. coli in the presence of a simple microbiome revealed pairwise and higher-order interactions, and underlying molecular mechanisms.

Distinct members of the Caenorhabditis elegans microbiota can have widely divergent effects on Orsay virus transmission, such that associated bacteria can effectively determine host susceptibility versus resistance to viral infection.
The spatial organization of pathogenic bacteria into microcolonies can be shaped by the stiffness of the substrate that they colonize, via modifications of the bacterial motility.
A systematical study of pslG mutants at both a single cell and community level reveals the importance of intracellular glycosyl hydrolase PslG on the cell fate and biofilm development of P. aeruginosa, an opportunistic pathogen that can cause persistent infections.
