Effects of AiiA-mediated quorum quenching in Sinorhizobium meliloti on quorum-sensing signals, proteome patterns, and symbiotic interactions.


Many behaviors in bacteria, including behaviors important to pathogenic and symbiotic interactions with eukaryotic hosts, are regulated by a mechanism called quorum sensing (QS). A "quorum-quenching" approach was used here to identify QS-regulated behaviors in the N-fixing bacterial symbiont Sinorhizobium meliloti. The AiiA lactonase from Bacillus produced… (More)
