Plants produce jasmonic acid and methyl jasmonate in response to many biotic and abiotic stresses (in particular, herbivory and wounding), which build up in the damaged parts of the plant. The methyl jasmonate can be used to signal the original plant’s defense systems or it can be spread by physical contact or through the air to produce a defensive reaction in unharmed plants. The unharmed plants absorb the airborne MeJA through either the stomata or diffusion through the leaf cell cytoplasm. Once absorbed, gaseous MeJA is converted to liquid jasmonic acid. An herbivorous attack on a plant causes it to produce MeJA both for internal defense and for a signaling compound to other plants.
