根际微生物组防控药用植物病害研究进展OA

Rhizosphere microbiome,regarded as the"second genome"of medicinal plants,can assist plants in resisting disease infection via various mechanisms such as nutritional competition,hyperparasitism,secretion of antimicrobial metabolite,and induced systemic resistance.Based on elucidating functional attributes of the rhizospheric microbiome,artificial directional regulation has emerged as a pivotal strategy for advancing green disease management in medicinal plants.This review systematically sorts current research and applications of rhizospheric microbiomes in controlling diseases of medicinal plants,revealing three principal research thrusts,such as the parsed characteristics of rhizospheric microbiome communities,elucidation of disease biocontrol mechanisms,construction and application of synthetic microbial communities.However,current challenges still exist,including chemical input-dependent pathogen resistance evolution,soil microecological imbalance,and excessive agricultural residues.Moreover,synthetic microbial consortia exhibit inadequate functional stability and poor field adaptability,representing critical technical barriers.The evolutionary trajectory of research methodologies demonstrates a progressive shift from microbial resource screening and single-functional validation to precision biocontrol systems.Recent advancements emphasize integrated applications of synthetic microbial assembly and rhizosphere ecological modulation,marking a paradigm shift from empirical approaches to function-driven strategies.Accordingly,this study proposes a three-dimensional synergistic development framework encompassing"functional compensation assembly-consortium intelligent construction-interaction system evaluation",aiming to provide a theoretical foundation and innovative pathway for achieving green,precise disease control in medicinal plants,and supports sustainable development in ecological agriculture of Chinese materia medica.
