摘　　要：在过去的三十年中,人们对诱导系统性抗性———这一普遍存在于高等植物抗病过程中的现象———进行了深入研究。被真菌、细菌或病毒侵染后,植物表现出广泛的、长时间的系统性抗性。在这一过程中,植物细胞壁组成成分发生改变,表达各种病原相关蛋白(PR蛋白) ,并合成多种植物抗毒素。本文就主要的PR蛋白家族的结构和功能特性,PR蛋白的发现和分类,及PR蛋白的应用作一综述。Induced systemic resistance (ISR)of higher plants against pathogens is a widespread phenomenon that has been intensively investigated in recently 30 years.Elicited by a local infection,plants respond with the systemic expression of a broad spectrum and long-lasting disease resistance that is efficient against fungi,bacteria and viruses.Changes in cell wall composition,production of pathogenesis-related (PR)proteins,and synthesis of phytoalexins are associated with resistance.In this paper,we will review structural and functional properties of major PR families,and will also discuss the discovery and structure classes of PR proteins,as well as application of PR proteins.
