FAD2 — Daucus carota subsp. sativus

Summary

DCAR_019845 (DcFAD2) on carrot chromosome 6 encodes a fatty acid desaturase with acyl-lipid omega-6 desaturase, omega-3 fatty acid desaturase, delta12 fatty acid acetylenase, oleate D12-hydroxylase, and monooxygenase activities. The product localises to the endoplasmic reticulum membrane and is associated with unsaturated fatty acid anabolism, fatty acid and lipid metabolism, and glycolipid desaturation. DcFAD2 has been connected to linoleic acid, alpha-linolenic acid, and xanthophyll content, as well as temperature stress responses, aphid response, water use efficiency, stomatal resistance, flower and seed development, disease tolerance, and salt tolerance. Studies of related genes in other species link the family to oleic acid content, fatty acid desaturation, salt tolerance, resistance to Botrytis cinerea, and seed oil composition.
