Researchers at the Hebrew University of Jerusalem have developed a new molecular sensor system to detect harmful diseases in plants and food crops, with a focus on late blight disease in potatoes and tomatoes. This system could potentially reduce global food insecurity by enabling early detection of the disease, which causes an estimated $6.5 billion in annual damage. The team achieved this by genetically engineering new potato varieties to produce distinctive proteins that act as a sensor, which can be monitored using sensitive cameras to track the plant's physiological state.

Researchers at the Hebrew University of Jerusalem have developed a new molecular sensor system that detects harmful diseases in plants and food crops, including potatoes and tomatoes. Potatoes have become the world’s third major food source. Early detection of late blight disease, which gave rise to the Irish Potato Famine, could help reduce global food insecurity. The disease is a leading cause of potato and tomato crop loss, costing an estimated $6.5 billion in annual damage worldwide. In a cover story published in The Plant Journal, researchers used genetic engineering methods to produce new potato varieties that produce distinctive proteins. These proteins act as a biological sensor that can be sent to the chloroplasts in the plant’s cells, where photosynthesis occurs. “In its early stages, it is difficult to identify the disease since you can’t see external signs on the leaf,” says Hebrew University doctoral ...
