细菌信号分子N-酰基高丝氨酸内酯调控植物抗性的研究进展

自然界中植物与细菌长期共存,共同进化,二者之间形成由不同信号分子介导的复杂的相互作用网络。N-酰基高丝氨酸内酯（AHLs）是革兰氏阴性细菌胞间通讯的信号分子,可被植物感知,并能调控植物多种生理行为,包括植物的天然免疫、生长发育、耐逆性等。本文综述近年来的相关研究进展,有助于全面了解植物与细菌间的信息交流机制,并对农业生产提供理论指导。

Advances in Regulation of Plant Resistance by N-Acyl-Homoserine Lactones,the Bacterial Quorum-Sensing Signals

Co-existence and co-evolution of plants and bacteria for millions of years have led to a complex interacting network mediated by a number of signal molecules between plants and bacteria.N-acyl-homoserine lactones（AHLs） are the signals for cell-to-cell communication in Gram-negative bacteria.Recent researches demonstrated that AHLs can be perceived by plants and can regulate a variety of plant physiological processes including plant innate immunity,growth and development,and abiotic tolerance.This review summarizes the recent findings in this field,provides insight into the inter-kingdom communication between plants and bacteria,and guides the manipulation for improving crop production in practice.
