The hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by pathogens. It involves the rapid death of cells in the local region surrounding an infection site, which can lead to the appearance of black, dead spots on the leaves. This is a form of localized immune response to contain the pathogen.
