FATB — Brassica juncea

Summary

BJUB02G03690S (BjFATB) on Indian mustard chromosome B02 encodes an acyl-ACP thioesterase of the FATA/B family, possessing acyl-ACP hydrolase activity and acyl carrier activity. The gene is associated with fatty acid anabolism, fatty acid beta-oxidation, cell growth, and seed germination, and its product localises to the plastid. It has been linked to cutin monomer composition and the hypersensitive response. Studies of related genes in other species connect the FATB family to palmitic acid content, oleic acid content, seed oil composition, seed coat hardness and permeability, seed viability, leaf oil content, wax biosynthesis, photochemical quenching, and plant growth and development traits, as well as to altered lipid metabolism and embryo lethal phenotypes.
