Chemical elicitors of systemic acquired resistance—Salicylic acid and its functional analogs

Any interaction of plants with phytopathogens involves the generation of various chemical molecules that are critical for activation of their defense machinery. One of the chemicals, salicylic acid (SA) induces systemic acquired resistance (SAR) in plants. The activation of SAR provides a broad-spectrum resistance against a wide range of related or unrelated pathogens. There has been considerable progress in the biochemical and molecular...
