This research investigates the natural biochemical defences that allow some maize plants to resist devastating fungal diseases. Using metabolomics, it identifies protective compounds produced by resistant plants and links them to specific genes. The findings could enable breeders to develop naturally disease-resistant crops, reducing reliance on costly and environmentally harmful fungicides.

Corn crops often suffer hidden stress long before visible damage appears. This research develops DNA aptamer-based biosensors that detect early stress signals in maize soil. By providing real-time alerts, the system enables faster intervention, improving crop resilience, farm productivity, and long-term food security.
