摘要:

根系分泌物作为地下防御物质越来越受到关注。近年来,研究逐渐揭示了植物在病原胁迫下根系分泌物的表达特征及其在植物抗病性中的作用,一些由根分泌物介导的抗性调节机制也已被模拟。鉴于土传病害造成的损失日益增加,了解根系分泌物如何抵抗各种病原菌已成为研究热点。本文全面综述了土壤病原胁迫下根系分泌物介导的植物抗性机制,研究病原胁迫下根系分泌物的表达特征,根系分泌物在植物抗病过程中的作用,以及抗性根介导的分泌物和植物抗性的功能。讨论了当前植物病害条件下根系分泌物对植物抗性的影响,旨在为今后土传病害抗性机制的研究提供思路。

Abstract:

Root exudates have gained increasing attention as underground defense substances. In recent years, studies have gradually revealed the expression characteristics of root exudates in plants under pathogenic stress, as well as their roles in plant disease resistance. Some resistance regulatory mechanisms mediated by root exudates have also been simulated. Given the growing losses caused by soil-borne diseases, understanding how root exudates resist various pathogenic bacteria has become a research focus. This article comprehensively reviews the plant resistance mechanism mediated by root exudates under soil pathogen stress. It examines the expression characteristics of root exudates under pathogen stress, the role of root exudates in the process of plant disease resistance, and the functions of secretions and plant resistance mediated by resistant roots. The article also discussed the impact of root secretions on plant resistance under current plant disease conditions, aiming to provide future insights into the study of resistance mechanisms of soil-borne diseases.

Key words: root exudates, soil-borne diseases, plant resistance
