Salicylate is an aromatic compound that is is common throughout the plant kingdom and is also found in some bacteria.

Several bacterial genera utilize salicylate as a building block for low-molecular-weight organic Fe3+ chelators (siderophores), such as yersiniabactin in Yersinia pestis and Yersinia enterocolitica, pyochelin in Pseudomonas aeruginosa, and mycobactin in Mycobacterium tuberculosis. In bacteria salicylate is derived from chorismate in two steps, via isochorismate, as described in this pathway.

Salicylate is also important in plants, where it induces flowering and is involved in resistance against pathogen infection through the systematic acquired resistance mechanism [Durrant04, Shah03]. While plants can make salicylate in more than one pathway (see salicylate biosynthesis II), genetic studies in Arabidopsis have shown that the bulk of salicylate is produced from chorismate [Wildermuth01].
