【摘要】 细菌根据特定信号分子的浓度可以监测周围环境中自身或其它细菌的数量变化 ,当信号达到一定的浓度阈值时 ,能启动菌体中相关基因的表达来适应环境中的变化 ,这一调控系统被称为细菌的群体感应调节系统 (Quo rum Sensing系统 )。本文系统介绍了细菌感知种内与种间数量的群体感应调节系统 ,并阐述了植物针对病原菌这一信号系统的抗病策略更多还原

【Abstract】 Bacteria can co ordinate group activities by cell cell communicate with each other. The interbacterial communication system known as quorum sensing(QS) utilizes hormones, such as acyl homoserine lactone(AHL), oligopeptide and furanosyl borate diester, to regulate bacterial gene expression. This review describes bacterial QS regulatory cascades of gram negative and postive bacteria. Finally we discuss strategy of anti QS system for plant controlling bacterial disease.更多还原
