Summary

ZM00001EB020680, designated ZmAOC, encodes an allene oxide cyclase (EC 5.3.99.6) with allene-oxide cyclase activity, a key enzyme in the jasmonic acid biosynthesis pathway. The gene is associated with hormone metabolism, carotenoid metabolism, ethene metabolism, and indole anabolism, and is linked to aerenchyma formation, developmental vegetative growth, and cellular respiration. ZmAOC localises to the chloroplast thylakoid membrane, chloroplast envelope, stromule, and other cellular compartments. The gene has been connected to agronomically important traits including grain yield, drought tolerance, heat tolerance, cold tolerance, salt response, water use efficiency, chlorophyll content, leaf size, plant height, germination rate, stomatal resistance, proline content, and mycotoxin content. Associations with rolled leaf, anther dehiscence, leaf senescence, and disease resistance have also been observed.
