Network-guided synthesis of antagonistic microbiota for suppressing maize stalk rot disease.

Network-guided assembly of a synthetic microbiota significantly suppresses maize stalk rot caused by Fusarium verticillioides and F. graminearum, with stronger effects than random communities.

• Why it matters: Understanding how pathogen invasion alters plant microbiomes and leveraging these changes can improve biocontrol strategies to protect crops from devastating diseases like maize stalk rot.
• What they did: Researchers integrated large-scale sequencing, network analysis, and experimental validation to identify negative interactions with Fusarium in maize microbiomes, then assembled and tested a synthetic microbial community (SynCom).
• The result: The refined SynCom effectively reduced disease severity by producing antifungal metabolites and activating host defenses, offering a promising approach for sustainable crop protection.
