FATB — Camelina sativa

Summary

CsFATB (CSA03G011960) on Camelina sativa chromosome 3 encodes an acyl-ACP hydrolase with acyl-ACP-thioesterase and HotDog domains, conferring acyl-ACP hydrolase activity and acyl carrier activity. The gene is associated with fatty acid elongation and anabolism, and its product localises to the plastid. CsFATB has been linked to oleic acid content, cutin monomer composition (particularly C16 components), and the hypersensitive response in MYB30-overexpressing backgrounds. Studies of related genes in other species link the FATB family to palmitic acid content, seed coat hardness, seed viability, photochemical quenching, plant growth and development, leaf oil content, wax biosynthesis, embryo lethality, seed oil composition and melting point, saturated fatty acid content, and seed coat permeability.
