Tema(s): Recursos en línea: Resumen: The hypersensitive response, or HR, is a form of cell death often associated with plant resistance to pathogen infection. Reactive oxygen intermediates and ion fluxes are proximal responses probably required for the HR. Apoptosis as defined in animal systems is, thus far, not a strict paradigmfor the HR. The diversity observed in plant cell death morphologies suggests that there may be multiple pathways through which the HR can be triggered. Signals from pathogens appear to interferewith these pathways. HR may play in plants the same oleas certain programmed cell death sinanimals with respect to restricting pathogen growth. In addition, the HR could regulate the defense responses of the plant in both local and distant tissues.
