AOC — Solanum tuberosum

Summary

PGSC0003DMG401012679, the potato AOC gene on chromosome 2, encodes an allene oxide cyclase (EC 5.3.99.6) with allene-oxide cyclase activity, a key enzyme in the jasmonic acid biosynthesis pathway. This gene is associated with the lipoxygenase pathway, oxylipin and jasmonic acid anabolism, and induced systemic resistance mediated by jasmonic acid signaling. It has been linked to responses to desiccation, vitamin B2, and metal, as well as developmental vegetative growth, phytoalexin biosynthesis, and upregulation of defense response to insect. Associations include tuber morphology, net photosynthetic rate, jasmonic acid content, leaf senescence, anther dehiscence, disease resistance, and tuber and seed development. The protein localizes to chloroplast thylakoid membranes, stromules, envelopes, and stroma, as well as the cytosol, mitochondria, and vacuole. Studies of related genes in other species link the family to herbivore defense and cold response.
