Systemic acquired resistance

Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen. SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution.^[1] The systemic acquired resistance response is dependent on the plant hormone, salicylic acid.
