FAD2 — Brassica oleracea

Summary

BoFAD2 (BOLC102_C01P058750.1) on cabbage chromosome 1 encodes a fatty acid desaturase with oleate D12-hydroxylase, omega-6 and omega-3 fatty acid desaturase, and monooxygenase activities. The product is localized to the endoplasmic reticulum membrane and nucleus. This gene is associated with unsaturated fatty acid anabolism and metabolism, as well as pachytene. It is linked to numerous agronomic traits including linoleic acid, alpha-linolenic acid, and seed protein content, along with plant height, seed viability, water use efficiency, stomatal resistance, and responses to temperature stress, aphids, and disease. Associations also include altered fatty acid composition, tocopherol deficiency, suppressed cold stress phenotypes, seed germination, cutin monomer composition, and endoplasmic reticulum stress tolerance. Studies of related genes in other species link the family to salt tolerance, Botrytis cinerea resistance, and aphid resistance.
