The major function of JA and its various metabolites is regulating plant responses to abiotic and biotic stresses as well as plant growth and development.  Regulated plant growth and development processes include growth inhibition, senescence, tendril coiling, flower development and leaf abscission. JA is also responsible for tuber formation in potatoes, yams, and onions. It has an important role in response to wounding of plants and systemic acquired resistance. When plants are attacked by insects, they respond by releasing JA, which activates the expression of protease inhibitors, among many other anti-herbivore defense compounds. These protease inhibitors prevent proteolytic activity of the insects' digestive proteases or "salivary proteins", thereby stopping them from acquiring the needed nitrogen in the protein for their own growth.
This chemical may have a role in pest control, according to an October 2008 BBC News report. Researchers at the UK's Lancaster University have signed a licensing deal with an American company to market jasmonic acid as a seed treatment. JA seed treatment stimulates the natural anti-pest defenses of the plants that germinate from the treated seeds, without harming plant growth as happens when jasmonates are sprayed onto plants that have already started growing.
