Abstract:Small, antimicrobial peptides are often produced by eukaryotes to control bacterial populations in both pathogenic and mutualistic symbioses. These include proline-rich mammalian immune peptides and cysteine-rich peptides produced by legume plants in symbiosis with rhizobia. The fitness of the bacterial partner is dependent upon their ability to persist in the presence of these antimicrobial peptides. In the case ofEscherichia coliandMycobacterium tuberculosispathogens and nitrogen-fixing legume symbionts (rhi… Show more
