DAD1 — Solanum tuberosum

Summary

StDAD1 (PGSC0003DMG400020999) on potato chromosome 8 encodes a lipoxygenase with linoleate 9S- and 13S-lipoxygenase activity, containing lipoxygenase and PLAT/LH2 domains. The enzyme is associated with the lipoxygenase pathway, oxylipin metabolism, lipid oxidation, membrane breakdown, and downregulation of defense responses to insects. It localizes to plastids and cytoplasm. The gene is linked to tuber development, starch content and yield, protein content, photosynthetic rate, respiration rate, and germination rate. Associations include pathogen resistance, drought tolerance, heat tolerance, salt tolerance, oxidative stress tolerance, aphid resistance, powdery mildew resistance, and resistance to Cucumber mosaic virus. It is also connected to seed aging tolerance, fatty acid oxidation, stomatal closure, cadmium stress response, and induced systemic resistance. Related genes in other species link the family to cold tolerance and disease resistance, leaf senescence, and lipid peroxidation.
