Quorum sensing is a common phenomenon in bacteria to control bacterial behaviour at the population level. Bacteria rely on quorum sensing signalling to modulate gene expression necessary to colonise certain environmental niches, or to successfully colonise host and cause diseases in case of pathogenic bacteria. However, the direct interaction of quorum sensing signals with host biological processes is poorly understood. Here, we present evidence that phytopathogenic bacterial quorum sensing signals are able to interfere with multiple plant cell biology, including basic cellular processes like endocytosis and plant immune responses using RNA-Seq together with multiple live-cell imaging approaches to monitor Arabidopsis cell responses to bacterial quorum sensing molecules.
