FAD2 — Daucus carota subsp. sativus

Summary

DCAR_027614 (DcFAD2) on carrot chromosome 8 encodes a fatty acid desaturase with acyl-lipid omega-6 desaturase, delta12 fatty acid acetylenase, omega-3 fatty acid desaturase, and oleate D12-hydroxylase activities. This endoplasmic reticulum membrane protein is associated with unsaturated fatty acid anabolism, fatty acid and lipid metabolism, and glycolipid desaturation. DcFAD2 is associated with linoleic and alpha-linolenic acid content, xanthophyll content, temperature stress responses, aphid response, flower and seed development, water use efficiency, stomatal resistance, disease tolerance, and salt tolerance. The gene is associated with aphid resistance, altered fatty acid composition, punicic acid accumulation, seed oil melting point, cold tolerance, mitochondrial respiration, and seed viability. Studies of related genes in other species link the family to oleate desaturation, salt tolerance, resistance to Botrytis cinerea, and ricinoleic acid accumulation.
