FAD2 — Camelina sativa

Summary

CSA01G013220 (FAD2-A) encodes a fatty acid desaturase with oleate Δ12-hydroxylase, omega-6 and omega-3 fatty acid desaturase, and monooxygenase activities, localised to the endoplasmic reticulum membrane. In Camelina sativa, this gene is associated with unsaturated fatty acid anabolism, lipogenesis, fatty acid elongation, and lipid metabolism, as well as the regulation of post-translational modification and hormone anabolism. It has been connected to alpha-linolenic acid, linoleic acid, and xanthophyll content, along with seed weight, seed viability, water use efficiency, stomatal resistance, temperature stress responses, aphid response, disease tolerance, and plant growth and development traits. Phenotypic associations include altered fatty acid composition, cold tolerance, seed oil melting point, and endoplasmic reticulum stress tolerance. Studies of related genes in other species link it to salt tolerance, Botrytis cinerea resistance, and ricinoleic acid accumulation.
