DAD1 — Solanum lycopersicum

Summary

SOLYC08G014000.3, also known as DAD1 or LOX1, encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, containing lipoxygenase and PLAT/LH2 domains. In tomato, this gene is associated with disease resistance and cold tolerance, and its product localizes to the plastid and cytoplasm. The gene is linked to numerous traits including fruit firmness, fruit color, fruit weight, lycopene content, carotenoid content, sugar content, and amino acid content, as well as seedling vigor, leaf width, leaf relative water content, shoot dry weight, net photosynthetic rate, water use efficiency, and respiration rate. It is associated with seed aging tolerance, oxidative stress tolerance, drought tolerance, heat tolerance, salt tolerance, powdery mildew resistance, Fusarium head blight resistance, and resistance to Cucumber mosaic virus. Studies of related genes in other species link the family to leaf senescence, lipid peroxidation, and osmotic stress tolerance.
