Two ion channels (structures in cell membranes that allow ions to pass through) have been genetically engineered to reveal the stress responses of plants non-invasively. When triggered by light, one channel provoked responses to osmotic stress (caused by water shortage) and the other induced immune responses to biotic stress (such as wounding or a pathogen).
