The hypersensitive response is a localized plant defense mechanism that occurs rapidly at the site of pathogen infection, resulting in programmed cell death and the activation of defensive processes. This response effectively limits the spread of the pathogen by creating a barrier and triggering additional immune responses, including the production of antimicrobial compounds. It plays a crucial role in both pathogen recognition and the establishment of broader induced defenses throughout the plant.
congrats on reading the definition of hypersensitive response. now let's actually learn it.
