摘　　要：N-酰基高丝氨酸内酯(AHLs)是重要的群体感应信号分子,主要参与调控根际革兰氏阴性菌的定植、细菌细胞代谢等生理行为、以及细菌和植物之间的信号转导。已有的研究表明,植物能够感知AHLs的存在并作出特异性的生理反应,但具体反应机制尚不明确。本文综述了植物感知AHLs后细胞内的信号转导机制、AHLs对植物生长发育和胁迫抗性的影响以及AHLs在农业生产领域的积极作用,为AHLs产品的开发以及在有机农业中的应用提供理论基础。N-Acyl homoserine lactones(AHLs) are important quorum-sensing signaling molecules, which are mainly involved in regulating physiological behaviors such as the colonization of rhizosphere Gram-negative bacteria, bacterial cell metabolism, and signal transduction between bacteria and plants. It has been shown that plants can sense the presence of AHLs and make specific physiological responses,but the exact response mechanism is unclear. This paper reviews the intracellular signal transduction mechanisms in plants after sensing AHLs, the effects of AHLs on plant growth and development and stress resistance, and the positive role of AHLs in agricultural production. It lays a theoretical foundation for the development of AHLs products and their application in organic agriculture.
