摘要
植物伯克霍尔德菌Burkholderia plantarii是引起水稻秧苗细菌性立枯病的重要病原菌之一,其侵染性、繁殖力及适应性均很强,严重威胁中国水稻生产。文章围绕B.plantarii的发生、危害及致病机理,着重论述了细菌群体感应系统(quorum sensing,QS)的生理功能及其在B.plantarii致病力调控方面的最新研究进展,并进一步从根际微生物互作角度,综述了种间信号分子对病原菌群体淬灭(quorum quenching)的作用机制,同时结合种间信号分子的独特性,展望了其在新型微生物杀菌剂研发中的重要性和应用潜力。
Burkholderia plantarii is a causal agent of bacterial seedling blight of rice. This pathogen is of strong infectivity, reproductive capacity and adapt ability, and thus poses a serious threat to rice production. Hereby, the occurrence, damage and pathogenic mechanism of B. plantarii are introduced.Research progress of physiological traits and the regulation of pathogenicity controlled by bacterial quorum sensing（QS） in B. plantarii are also discussed. Moreover, from the point of view of microbial interaction in rhizosphere, the mechanisms of quorum quenching by interspecific signaling molecules against bacterial pathogens are summarized. According to the characteristics of the interspecies signaling molecules, their importance and application potential in development of novel bactericides are also previewed.
