In many plants, localized tissue damage elicits an array of systemic defense responses against herbivore attack. Progress in our understanding of the long-distance signaling events that control these responses has been aided by the identification of mutants that fail to mount systemic defenses in response to wounding. Grafting experiments conducted with various mutants of tomato indicate that systemic signaling requires both the biosynthesis of jasmonic acid at the site of wounding and the ability to perceive a jasmonate signal in remote tissues. These and other studies support the hypothesis that jasmonic acid regulates the production of, or acts as, a mobile wound signal. Following its synthesis in peroxisomes, further metabolism of jasmonic acid might enhance its stability, transport, or action in remote tissues. Recent studies in tomato suggest that the peptide signal systemin promotes long-distance defense responses by amplifying jasmonate production in vascular tissues.
