FATB — Camelina sativa

Summary

CSA17G011970 (FatB2) in Camelina sativa encodes an acyl-ACP thioesterase, a plastid-localised enzyme with acyl-ACP hydrolase activity that belongs to the FATA/B and HotDog domain superfamilies. This gene is associated with fatty acid elongation, fatty acid anabolism, and lipid metabolism, and has been linked to oleic acid content as well as cutin monomer composition and the hypersensitive response in MYB30-overexpressing backgrounds. Studies of related genes in other species connect the FATB family to palmitic acid content, seed coat hardness, seed viability, photochemical quenching, plant growth, and fatty acid composition, including saturated fatty acid content and seed oil melting point. These cross-species associations highlight the family’s broad relevance to lipid metabolism and seed quality traits.
