DAD1 — Cucumis sativus

Summary

CsDAD1 (CSA_2G023900) on cucumber chromosome 2 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity and oxidoreductase activity acting on single donors with incorporation of molecular oxygen. The enzyme localises to plastids and the cytoplasm. CsDAD1 is associated with jasmonic acid and fatty acid anabolism, 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 lateral root formation. The gene is associated with pathogen resistance, including powdery mildew and Cucumber mosaic virus resistance, as well as tolerance to drought, heat, salt, oxidative stress, and seed aging. Associations also include photosynthetic and respiration rates, fruit aroma, stomatal closure, seed germination, and tuber development. Studies of related genes in other species link the family to cold tolerance, leaf senescence, and aphid resistance.
