Locking away a fungal poison to protect cereal crops.

myo-inositol metabolism promotes PI(4,5)P2 production that drives deoxynivalenol (DON) trafficking into vacuoles for sequestration, conferring Fusarium resistance in crops.

• Why it matters: DON disrupts plant central metabolism, and understanding how plants limit toxin movement is key to improving crop resilience against Fusarium.
• What they did: Xia et al. show DON hijacks NAD+-dependent metabolic enzymes, then identify a myo-inositol–linked pathway that increases PI(4,5)P2 to route DON into vacuoles.
• The result: Vacuolar sequestration of DON is linked to Fusarium resistance in crops, suggesting this metabolic routing can be targeted to protect cereal production.
