The Role of Salicylic Acid as a Plant Signal Molecule

The salicylates are a widely distributed class of aromatic compounds. Modifications of the free acid result in a diverse array of compounds such as salicin, the salicyl alcohol glucoside, and methylsalicylate (oil of wintergreen). First isolated from willow (Salix), salicylates have been used as folk remedies since the 4th century B.C. (Weissman, 1991). Salicylates are currently used as antimicrobials, food preservatives and analgesics.
