植物抗病性及诱导抗性在匍匐翦股颖病害防治中的应用

Induction of plant disease resistance and its application for disease control in creeping bentgrass

针对目前匍匐翦股颖草坪病害防治的弊端,引入诱导植物抗病性的概念,从信号传导、基因表达水平、细胞防御结构和生理响应等层面阐述了诱导抗病性后植株体所发生的变化规律;系统揭示了基于SAR和ISR方式的植物抗病性诱导机理。着意综述了诱导植物抗病性理论和研究成果在匍匐翦股颖病害控制中的应用状况,旨在为匍匐翦股颖新型、环保的草坪病害管理实践提供理论指导。

Induction of disease resistance was utilized to improve disease prevention and control in the turf grass,creeping bentgrass.This paper expounds the changes occurring after induced disease resistance (IDR)in plants,including gene expression signals,gene expression levels,cell defense mechanisms and physiological re-sponses,and systematically reveals the mechanism of induction of disease resistance based on systematic ac-quired resistance (SAR)and induced systematic resistance (ISR)pathways.The application of IDR theory in plants to creeping bentgrass disease control and associated research achievements are reviewed with the aim of providing a theoretical basis for new and environment-friendly disease management methods for turf grass.
