The morphogenesis and defense evolution of plants are intricately linked to soil microbial community dynamics, where beneficial and pathogenic bacteria regulate ecosystem stability through chemical signaling. A microbial communication mechanism known as quorum sensing (QS), which affects population density, virulence, and biofilm formation, substantially impacts plant development and immune responses. However, plants have developed strategies to detect and manipulate QS signals, enabling bidirectional interactions that influence both plant physiology and the balance of the microbiome. In this review, QS signals from bacteria, fungi, and nematodes are systematically examined, emphasizing their recognition by plant receptors, downstream signaling pathways, and the activation of defense responses. Most significantly, attention is given to the role of fungal and nematode QS molecules in modulating plant microbe interactions. By elucidating these communication networks, we highlight their potential applications in sustainable agriculture, offering novel insights into crop health management and ecosystem resilience.
植物的形态发生和防御进化与土壤微生物群落动态密切相关，其中有益菌和病原菌通过化学信号调节生态系统稳定性。一种称为群体感应（QS）的微生物通讯机制会影响种群密度、毒力和生物膜形成，对植物发育和免疫反应有重大影响。然而，植物已开发出检测和操纵QS信号的策略，实现了双向相互作用，影响植物生理和微生物群落平衡。在本综述中，系统研究了来自细菌、真菌和线虫的QS信号，重点关注植物受体对它们的识别、下游信号通路以及防御反应的激活。最重要的是，关注真菌和线虫QS分子在调节植物-微生物相互作用中的作用。通过阐明这些通讯网络，我们强调了它们在可持续农业中的潜在应用，为作物健康管理和生态系统恢复力提供了新见解。
