摘　要：

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。

Abstract:

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.

Key words: bacteria; N-acyl-homoserine lactone; plant; resistance
