SAR is executed upon the pathogen attack over plants, while ISR is switched on through colonization by PGPR (Van Loon et al., 1998, Kloepper and Beauchamp, 1992 ).

Induced resistance of plants has 2 major modes of action: the SAR pathway and the ISR pathway. SAR can elicit a rapid local reaction, or hypersensitive response, the pathogen is limited to a small area of the site of infection. As mentioned, salicylic acid is the mode of action for the SAR pathway. ISR enhances the defense systems of the plant by jasmonic acid (JA) mode of action. Both act on the effect of the NPR-1, but SAR utilizes PR genes.
