From metabolic fingerprints to field solutions: engineering the apple rhizosphere microbiome via host-directed Bacillus recruitment for sustainable apple replant disease control

Our findings elucidate an apple replant disease resistance mechanism in apple rootstocks involving lysine-mediated recruitment of protective Bacillus, which enhances rhizosphere microbiome stability and suppresses soil pathogenic Fusarium. Developed a technology for synergistic control of apple replant disease using Bacillus-lysine. The research results provide theoretical basis and practical solutions for green control of apple replant disease based on precise regulation of rhizosphere microbiome. Video Abstract.
