FAD2 — Camelina sativa

Summary

CsFAD2 (CSA19G016350) on Camelina sativa chromosome 19 encodes a fatty acid desaturase with oleate D12-hydroxylase, omega-6 and omega-3 fatty acid desaturase, and acyl-lipid omega-6 desaturase activities. The gene is associated with fatty acid elongation, unsaturated fatty acid anabolism, and fatty acid metabolism, and localises to the endoplasmic reticulum membrane. CsFAD2 is linked to alpha-linolenic acid, linoleic acid, and oleic acid content, as well as seed viability, seed growth and development, and seed oil composition. It has been linked to temperature stress response, including high and low temperature stress response, drought tolerance, water use efficiency, stomatal resistance, and disease tolerance. Additional associations include xanthophyll content, aphid response trait, flower development trait, and plant growth and development trait. Studies of related genes in other species link the family to salt tolerance, Botrytis cinerea resistance, and aphid resistance.
