Scientists Create Autoluminescent Plants to Detect Stress from Herbivore Attacks

Researchers have engineered the first autoluminescent plants that glow under stress, providing real-time visualization of plant responses. Developed by scientists from the MRC Laboratory of Medical Sciences, the Czech Academy of Sciences, and the startup Planta, these plants emit fluorescence when damaged, triggered by calcium signaling that activates defense genes. This innovation could enhance sustainable agriculture by enabling the creation of resilient crop varieties that require fewer pesticides.
