A fungus is threatening the world’s food supply. Scientists just found a new defense

Scientists have discovered a potential new weapon against a devastating fungus that threatens rice, wheat, and barley worldwide. By engineering a special type of plant immune receptor, researchers created defenses capable of recognizing multiple fungal threats at once. The breakthrough could eventually lead to crops with powerful, long-lasting disease resistance, helping protect a global food supply increasingly threatened by spreading infections and climate change.

By engineering the natural immune defenses of plants, researchers have developed an experimental approach that could eventually help wheat, rice, and barley resist fungal infections more effectively. The international research team, led by scientists at the John Innes Centre in the United Kingdom, investigated a recently discovered group of plant immune receptors. They identified how these proteins recognize invading pathogens and demonstrated that they can be modified to detect multiple fungal threats.
