Jasmonates are essential phytohormones for plant development and survival. They are the major lipid in the jasmine scent. However they are important in plant development processes, response to environmental stress, wounding , water deficit, and pathogen and pest attacks, root growth , fruit ripening, tendril coiling, reproductive development and senescence. .
They are synthesised from linolenic acid, and are structurally related to prostaglandins.
