Jasmonic and salicylic acids are the major hormones involved in plant response to pests and pathogens. Here, we engineered autoluminescent plants that report activity of these hormones with up to 53-fold contrast. Using consumer-grade cameras, we imaged reporter Arabidopsis thaliana and Nicotiana benthamiana plants throughout normal development, and in response to attacks of pests and pathogens.
