(±)-Jasmonic acid

(±)-Jasmonic acid is an endogenous growth regulator closely related to plant resistance to abiotic stresses, used to activate defense responses to wounding, herbivory, and pathogen attacks. (±)-Jasmonic acid does not play an independent regulatory role, but works in a complex signaling network with other plant hormone signaling pathways. In addition, (±)-Jasmonic acid can also reduce chlorophyll levels in green and etiolated barley leaf segments and inhibit the elongation of rice seedlings[3][4].
