With the development of biological control, people pay more and more attention to plant promoting bacteria, which can be used as biological agent against most of fungi pathogens play an important role in agricultural production and environmental protection. In most of gram negative(G-) bacteria, N-acylhomoserine lactones(AHLs)-mediated quorum-sensing(QS)systems is not only involved in the regulation of various physiological behavior and biological function, but also affect the interaction between bacterial and host plants and the expression of plant genes. In order to better exploit and utilization of biocontrol bacteria, this paper summarized the studies of AHLs regulating plant growth and resistance by crossover signal transduction,while the prospects are forecasted in order to provide some new ideas for the improvement of plant resistance and growth, and hoping to improve the plant resistance and promote growth to provide some new ideas.
