FAD3 — Camelina sativa

Summary

CsFAD3 (CSA05G033930) in Camelina sativa encodes a fatty acid desaturase with omega-3 and omega-6 fatty acid desaturase activity, functioning as an acyl-lipid omega-6 and omega-3 desaturase. This gene is associated with the Kennedy pathway, fatty acid elongation, unsaturated fatty acid anabolism, and lipid metabolism, as well as brassinosteroid and lignin anabolism. It is linked to seed coat and endosperm development, seedling development, and cold acclimation. The protein localizes to chloroplast and ER membranes. CsFAD3 is associated with alpha-linolenic and linoleic acid content, seed viability, seed size, photosynthetic rate, water use efficiency, stomatal resistance, and responses to temperature stress, aphids, and disease. Studies of related genes in other species link the family to linolenic acid content, cold tolerance, aphid resistance, and salt tolerance.
