BCCP — Brassica napus

Summary

BnBCCP (BCCP) on chromosome A02 of oilseed rape encodes a biotin carboxyl carrier protein of acetyl-CoA carboxylase, a component of the ACCase complex. The protein contains biotin-binding and lipoyl domains and localises to the plastid, chloroplast envelope and stroma. The gene is associated with acetyl-CoA carboxylase activity and biotin binding, and has been linked to lipid storage, triglyceride and fatty acid anabolism, lipid metabolism, seed development, embryogenesis, circadian rhythm, and chlorophyll content. Phenotypic associations include oil and fatty acid accumulation, pollen and embryo development, and plant growth. Studies of related genes in other species link the family to acetyl-coenzyme A carboxylase activity and embryo lethality.
