FAD3 — Camelina sativa

Summary

CsFAD3 (CSA16G014970) in Camelina sativa encodes a fatty acid desaturase with omega-3 and omega-6 fatty acid desaturase activities, as well as delta12 fatty acid acetylenase and linolenate delta15 desaturase functions. The gene is associated with fatty acid elongation, lipogenesis, unsaturated fatty acid anabolism, and lipid metabolism, and has been linked to seed coat and endosperm development, cold acclimation, and lignin anabolism. The encoded protein localizes to the chloroplast membrane, ER membrane, and nucleus. CsFAD3 is associated with alpha-linolenic acid and linoleic acid content, seed viability, seed size, photosynthetic rate, water use efficiency, stomatal resistance, temperature stress responses, aphid response, disease tolerance, and flower development. Related genes in other species are linked to linolenic acid content, cold tolerance, aphid resistance, and salt tolerance.
