Plant Biology Research Explores Early Disease Detection in Agriculture

Startups are using gene editing and sensors to program plants to emit signals, such as a glow or purple leaves, when facing insect or disease attacks. Alexander Jones, a professor at the University of Cambridge, noted that while plants naturally show signs of struggle, these signs often appear too late for effective intervention.

This technology allows farmers to treat small sections of crops as needed instead of spraying large swaths of farmland. This targeted approach could reduce the reliance on fungicides and herbicides, which currently leach into soil and waterways.
