-dominated cyanobacterial blooms (MCBs) frequently occur in freshwaters worldwide due to massive colony formation and severely threaten human and ecosystem health. Quorum sensing (QS) is a direct cause of colony formation that drives MCBs outbreak by regulating population characteristics and behaviors. Many novel findings regarding the fundamental knowledge of the QS phenomenon and the signaling molecules have been documented. However, little effort has been devoted to comprehensively summarizing and discussing the research progress and exploration directions of QS signaling molecules-mediated QS system in . This review summarizes the action process of N-acyl homoserine lactones (AHLs) as major signaling molecules in and discusses the detailed roles of AHL-mediated QS system in cellular morphology, physiological adaptability, and cell aggregation for colony formation to strengthen ecological adaptability and competitive advantage of The research progress on QS mechanisms in are also summarized. Compared to other QS systems, the LuxI/LuxR-type QS system is more likely to be found in . Also, we introduce quorum quenching (QQ), a QS-blocking process in , to emphasize its potential as QS inhibitors in MCBs control. Finally, in response to the research deficiencies and gaps in QS, we propose several future research directions in this field. This review deepens the understanding on QS knowledge and provide theoretical guidance in developing strategies to monitor, control, and harness MCBs.
