FATB — Brassica juncea

Summary

BJUA09G03300S (BjFATB) encodes a protein with acyl-ACP thioesterase domains of the FATB family, possessing acyl-ACP hydrolase activity and acyl carrier activity. This gene is associated with fatty acid anabolism, fatty acid beta-oxidation, cell growth, and seed germination, and its product localises to the plastid. BjFATB has been linked to cutin monomer composition, particularly C16 components, and to the hypersensitive response in MYB30-overexpressing backgrounds. Related genes in other species are associated with palmitic acid content, oleic acid content, seed coat hardness, seed viability, photochemical quenching, and plant growth and development traits. They are also associated with leaf oil content, wax biosynthesis, altered lipid metabolism, reduced growth rate, increased fatty acid synthesis, embryo lethality, seed oil melting point, saturated fatty acid content, seed oil composition, and seed coat permeability.
