| 摘 要： | 细菌的群体感应系统(Quorum-sensing,QS)作为一种细胞的信号转导机制,是细菌通过特定的信号分子浓度来监测周围环境中本身或其它细菌的数量变化,当信号分子达到浓度阈值时,能够启动菌体中相关的基因表达来适应环境变化的一种调控机制。笔者综述了细菌群体感应系统的分类,并对其应用前景进行了展望。

| Abstract: | Quorum-sensing is a regulatory mechanism,with which the bacteria will release a number of specific signaling molecules,which regulate the group behavior of the specie or other species in the same environment.When the signaling molecules density reaches a critical threshold,bacteria can alter the gene expression to suit the change of environment.This review focuses on the classification of Quorum-sensing,and describes the forecast of application. |
