Abstract: The phenomenon of information exchanging through signal molecules between microbial cells is the Quorum Sensing(QS). QS is widely present in microorganisms,and can modulate the expression of specific genes,especially virulence factors in pathogenic microorganisms. Quorum Quenching(QQ)is a new therapeutic strategy of plant diseases based on QS. QQ can be achieved by interfering QS from inhibiting the synthesis or detection of the signal molecules,or by enzyme-catalyzed degradation or modification of the signal molecules. Degrading signal molecules by using QQ enzymes is one of the most effective and nontoxic ways of QQ. So far,QQ enzymes of various microbial signaling molecules have been reported,especially N-acyl homoserine lactones(AHLs)and cis-11-methyl-2-dodecenoic acid were deeply investigated. In this review,we summarize and analyze the research status,deficiencies and the future development of QQ enzymes and their control of plant diseases,for laying a solid foundation for developing new,green and safe measures of disease control.

Key words: quorum sensing, quorum quenching enzymes, N-acyl homoserine lactones, cis-11-methyl-2-dodecenoic acid
