Abstract
Unlike animals, plants defend invading pathogen by equipping a variety of resistance mechanisms. The programmed cell death is the one which restrict the pathogen to spread further. Plant also develops induced resistance mechanism such as hypersensitive and systemic acquired resistance upon pathogen infection. All these mechanisms are active according to the one gene one enzyme theory. Pathogenesis-related (PR) gene expresses themselves by synthesizing pathogenic related protein which intern activate the various kinds of resistance mechanism to ward off the pathogens.
