Rhizosphere metagenomics, metabolomics, in situ fluorescent labeling and pot-pathogen infection validation were integrated to dissect flora interaction mechanisms.
Key Findings
The garlic root exudate DADS induces ROS-mediated stress damage in rhizosphere Penicillium strains while recruiting pathogen-inhibiting beneficial microbes to form an altruistic defensive microbiome shield.
This microbial community structure exerts long-term suppression of typical soil-borne pathogens such as Fusarium and alleviates soil degradation caused by continuous cropping.
Field-applicable precise regulation strategies for rhizosphere microbiomes via directional root recruitment were proposed.
