Hypersensitive response

In plant immunology, the hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens. HR is characterized by the rapid death of cells in the local region surrounding an infection, and it serves to restrict the growth and spread of pathogens to other parts of the plant. It is analogous to the innate…
