DAD1 — Cucumis sativus

Summary

CsDAD1 (CSA_2G023880) on cucumber chromosome 2 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity, acting as an oxidoreductase that incorporates molecular oxygen. The enzyme localises to plastids and the cytoplasm and is associated with jasmonic acid and oxylipin anabolism, lipid oxidation, membrane breakdown, and responses to wounding, abscisic acid, and jasmonic acid. It is linked to defence response to bacteria, downregulation of defense response to insect, systemic acquired resistance, and root development. The gene is associated with photosynthetic rate and respiration rate, and with seed germination, seed aging tolerance, fruit aroma, and tolerance to drought, salt, heat, and oxidative stress. It is also associated with resistance to powdery mildew, Cucumber mosaic virus, Fusarium head blight, and aphids, as well as stomatal closure and stomatal immunity.
