Systemic acquired resistance (SAR) is a type of acquired resistance that spreads throughout a plant following an initial attack by a pathogen. It allows the plant to mount a more efficient defense against future attacks. In this case, the corn plants that were attacked by the smut fungus have likely developed SAR, making them more resistant to further attacks by the same or similar pathogens. Tolerance (A) is the ability of a plant to withstand a certain level of damage without reducing its productivity. General acquired resistance (B), on the other hand, is a broad, non-specific response to pathogens that is induced by a previous pathogen attack. Antifungal proteins (D) and antifreeze proteins (E) are specific types of proteins that plants may produce to defend themselves against pathogens and/or environmental stressors, but their production is not necessarily indicative of SAR.
