Mechanisms of Root Exudates-mediated Plant Resistance to Soil-borne Diseases
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.
