Molecular enhancements help plants light up when they're under attack

Imagine that plants could tell us exactly when they're stressed, infected, or being eaten by insects, by lighting up. A new study led by Dr. Karen Sarkisyan, Head of the Synthetic Biology group at the MRC Laboratory of Medical Sciences (LMS), has borrowed molecular machinery from mushrooms and inserted it into plants to do just that. In a paper published in Nature Communications, the scientists engineered plants that could glow in the dark whenever their natural immune systems switch on.
