AAD1 — Cucumis sativus

Summary

CsAAD1 (CSA_2G351530) encodes a stearoyl-CoA 9-desaturase and stearoyl-[ACP] desaturase, placing it in the fatty acid desaturase-2 family. The gene is associated with unsaturated fatty acid anabolism, lipogenesis, and fatty acid homeostasis, and is linked to jasmonic acid and salicylic acid-mediated signaling pathways, defense responses to insects and bacteria, and antiviral responses including resistance to Cucumber mosaic virus. It has been connected to endosperm development, protein processing, and nitric oxide storage, and localizes to the chloroplast thylakoid and stroma. Associations also include seed oil content, oleic acid content, omega-7 and omega-9 fatty acid content, respiration rate, dwarfism, cell death, and cuticle development. Studies of related genes in other species link the family to spontaneous lesion formation, enhanced pathogen resistance, and altered fatty acid composition.
