Usage and action mechanism of oxylipins including jasmonic acid on physiological aspects of fruit production

•Jasmonoyl-L-isoleucine (JA-Ile) is a transporting and signaling substance for JA action in plants.•Jasmonates enhance anthocyanin formation through JA-Ile, MYC, JAZ, bHLH, TRB, HIR, NINJA, JAM, MYB, and UF3GT in fruit.•Jasmonates crosstalk with other plant hormones.•Jasmonates mitigate abiotic and biotic stresses through the increase in secondary metabolites in plant.
