摘 要:

为争夺各自的生存资源和空间, 自然万物之间既相互联系又相互战斗。植物同病原微生物以及益生微生物之间也在长期的相互斗争中一起协同进化, 最终维持在一个相对稳定的状态。从农耕文明发展至今, 植物病害造成的损失不计其数, 所以对植物与病原微生物, 以及益生微生物之间关系的阐释和植物抗病信号途径中各成员功能的揭示, 对未来农业的可持续发展将起到极其重要的作用。近年来, 基于分子生物学、遗传学和生理生化检测技术的飞速发展, 研究者对植物抗病信号途径, 尤其是植物模式识别受体与先天免疫的关系有了一些初步认知, 对深入认识植物同微生物之间协同进化的关系奠定了基础。本文综述了近年来植物模式识别受体识别外源或内源免疫触发因子从而触发植物先天免疫信号的最新研究进展, 以期为阐释植物同微生物之间的关系提供理论依据, 并为培育符合社会发展需求的抗病作物提供一定指导。

Abstract:

In order to fght for their own living resources and space, natural things are interrelated and exclusionary with each other. In a long struggle, plants co-evolved with benefcial or pathogenic microorganisms, and maintain a relatively stable state in the end. Since the initiation of agricultural civilization, plant diseases have caused untold losses. If we clearly explain the relationship between plants and benefcial or pathogenic microorganisms and know the functions of each member in the plant disease resistance signal pathways, it will be beneficial to the sustainable development of agriculture in the future. In recent years, based on the development of molecular biology, genetics, physiological and biochemical detection techniques, researchers have gained some preliminary understanding of plant disease resistance, especially the relationship between plant pattern recognition receptors and innate immunity, this laying the foundation for a deeper understanding of the co-evolutionary relationship between plants and microorganisms. In this review, we discussed the recent advances in plant pattern recognition receptors and exogenous or endogenous elicitor. Look forward to providing a theoretical basis to explain the relationship between plants and microorganisms, and provide guidance to cultivation of disease-resistant crops which meet the needs of social development.

Key words: pattern recognition receptors; receptor-like protein kinases; receptor-like protein; innate immunity
