Myo-inositol metabolism counteracts mycotoxin hijacking and confers broad resistance to fungal diseases in crops.

Elevated MIPS expression in wheat and maize confers up to 88% reduction in DON accumulation and rescues 43% yield loss, providing broad resistance to Fusarium diseases.

• Why it matters: Fusarium pathogens produce mycotoxins like DON to promote disease, causing significant crop yield loss and food safety issues, yet the mechanisms of mycotoxin-crop interactions remain unclear.
• What they did: The study identified that DON hijacks plant NAD+-dependent enzymes and disrupts metabolism, but increased MIPS redirects myo-inositol-phosphoinositide metabolism, promoting DON sequestration into vacuoles.
• The result: This sequestration prevents metabolic disruption and FHB development, establishing a metabolic framework that enhances crop resistance and offers a promising strategy for mycotoxin management.
