Plant responses to bacterial quorum sensing signals

Curr Opin Plant Biol. 2004 Aug;7(4):429-33. doi: 10.1016/j.pbi.2004.05.008.


Bacterial infection of plants often depends on the exchange of quorum sensing signals between nearby bacterial cells. It is now evident that plants, in turn, 'listen' to these bacterial signals and respond in sophisticated ways to the information. Plants also secrete compounds that mimic the bacterial signals and thereby confuse quorum sensing regulation in bacteria.
