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
611:(root) coiling, flowering, seed and fruit maturation. An increase of the hormone affects flowering time, flower morphology and the number of open flowers. MeJA induces ethylene-forming enzyme activity, which increases the amount of ethylene to the amount necessary for fruit maturation.
614:
Increased amounts of methyl jasmonate in plant roots have shown to inhibit their growth. It is predicted that the higher amounts of MeJA activate previously unexpressed genes within the roots to cause the growth inhibition.
597:. Plants treated with methyl jasmonate and exposed to insect herbivores had significantly lower levels of herbivory, and the insect herbivores had slower development, when compared to untreated plants.

plants were shown to alter their metabolism and were better able to withstand water stress and drought conditions by lowering the amount of transpiration, and membrane-lipid peroxidation.
