摘要
植物促生菌具有抗病和促生的潜能,在农业生产及环境保护方面都具有重要的作用。在许多革兰氏阴性细菌中,N-乙酰基高丝氨酸内酯(AHLs)介导的群体感应(QS)系统不仅参与对细菌多种生理行为和生物学功能的调控,而且影响植物基因的表达及细菌与宿主植物间的互作。为了更好地开发利用生防菌,综述了多年来对AHLs跨界信号转导参与调节植物生长发育和抗逆性的研究,并对该领域今后的研究方向进行了展望,以期为改善植物抗逆性和促进生长提供一些新思路。
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.
