摘要
植物可由外源蛋白质、糖类、有机酸等诱导产生抗性,通过受体识别、信号传导产生防御反应.利用植物诱导免疫的机理,开发出蛋白类、生防菌类、寡糖类等多种植物免疫诱抗剂,在提高农作物抗病性、抗逆能力、增加产量和提高品质等方面表现出巨大的应用潜力.本文概述了植物免疫反应的原理和类型、免疫反应的3个过程以及免疫激发子和诱抗剂的种类,系统性诠释植物免疫机制,进一步分析了目前植物免疫诱抗剂使用存在的问题,并对植物免疫诱抗剂开发的未来发展趋势等方面进行了展望.研究结果为植物免疫诱抗剂的基础研究、产业化开发和田间应用等方面提供了科学依据.
Resistance could be induced by exogenous proteins,carbohydrates and organic acids,including three processes of receptor recognition,signal transduction and defensive response.Based on the mechanism of plant-induced immunity,many kinds of plant immune inducers such as proteins,biocontrol bacteria and oligosaccharides were developed,which showed great application potential in improving disease resistance,stress resistance,yield and quality of crops.In this paper,the principles and types of plant immunity response,the three processes of plant immunity response and the types of immunity elicitors and immunity inducers were summarized.The plant immunity mechanism was systematically explained,and the problems and development trend of plant immunity inducers were further analyzed.This paper provided a scientific basis for the basic research,industrial development and field application of plant immunity inducers.
