FATB — Camelina sativa

Summary

CsFATB (CSA14G009990) encodes an acyl-ACP thioesterase, a plastid-localised enzyme with acyl-ACP hydrolase activity that belongs to the FatB family. In Camelina sativa, this gene is associated with fatty acid elongation and anabolism, oleic acid content, and cutin monomer composition, particularly C16 monomers. It has also been linked to 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 and permeability, seed viability, seed oil composition and melting point, leaf oil content, wax biosynthesis, photochemical quenching, and overall plant growth and development. These transferred associations also connect the family to altered lipid metabolism, reduced growth rate, increased fatty acid synthesis, and embryo lethality.
