AOC — Medicago truncatula

Summary

MTR_5G053950 (symbol AOC, preferred name MtAOC1) encodes an allene-oxide cyclase with allene-oxide cyclase activity. In barrel medic, this gene is associated with jasmonic acid and unsaturated fatty acid anabolism, as well as responses to insects, fungi, hydrogen peroxide, desiccation, and various light conditions including blue, red, and far-red light. It is linked to photoperiodism and flowering, developmental vegetative growth, and induced systemic resistance mediated by jasmonic acid signaling. The encoded protein localizes to chloroplast thylakoid membranes, chloroplast envelope, stroma, stromules, and also to the cytosol, plasma membrane, mitochondria, and extracellular regions. Associations with anther dehiscence, leaf senescence, and disease resistance have been noted. Studies of related genes in other species link the family to cold response and jasmonic acid content.
