Abstract: Bacterial quorum-sensing is involved in the regulation of diverse biological process including the virulence of plant and animal bacterial pathogens. The current evidences show that plant can sense bacterial quorum-sensing (QS) and the QS signal， and response in a complex way to these information. Plant can initiate its defense system upon sensing bacterial QS signal or secret QS signal mimics or produce enzymes which are able to degrade bacterial QS signal to block or interfere bacterial QS.
