Research progress in allelopathy of root exudates from resistant and susceptible crop varieties to soil-borne diseases
摘要
Abstract
Root exudates can regulate the incidence of soil-borne diseases via direct or indirect allelo-pathic effects.Based on the fundamental characteristics and influencing factors of allelopathy,this paper systematically reviews the compositional differences in root exudates between disease-resistant and susceptible crop varieties,and elaborated their regulatory effects on pathogen propagation,dis-ease development and rhizosphere microbial communities.The rhizosphere of resistant varieties accu-mulates abundant esters,phenolic acids,saponins and other bioactive compounds including cinnamic acid,methyl ferulate and soyasaponin I.These substances effectively suppress the proliferation of soil-borne pathogens,elevate the relative abundance of beneficial rhizospheric microorganisms such as Bacillus,reconstruct a healthy rhizosphere microecosystem,and thereby reduce crop disease risks.In contrast,susceptible varieties secrete massive amounts of organic acids,saccharides and amino acids,which serve as nutritional substrates for pathogen colonization and reproduction,accelerating the spread and epidemics of soil-borne diseases.Future research should systematically investigate how collection methods affect the detection of root exudate components,accurately identify core disease-suppressive allelochemicals and dissect their molecular resistance mechanisms,and uncover the interactive regulatory network between root exudates and rhizosphere microorganisms.Mean-while,novel analytical techniques such as nuclear magnetic resonance(NMR)should be applied in allelopathy research to establish a targeted breeding system based on rhizosphere chemical defense.This review aimed to provide solid theoretical foundations and technical support for improving the theoretical framework of crop disease resistance and facilitating the precision breeding of disease-resistant varieties.关键词
