FAE1 — Brassica napus

Summary

BnFAE1 (FAE1) on chromosome C03 of oilseed rape encodes a protein with domains including FAE1-type polyketide synthase, 3-ketoacyl-CoA synthase, and acyltransferase activity. The enzyme is associated with very-long-chain fatty acid biosynthesis, elongation, and metabolism, as well as fatty acid and lipid anabolism, polyketide and flavonoid biosynthesis, seed development, and lipogenesis. It has been linked to seed oil content and composition, including oleic, linoleic, and eicosenoic acid levels, seed weight, protein content, and pollen fertility. The protein localises to the endoplasmic reticulum and membrane. Studies of related genes in other species connect the family to erucic acid content, very-long-chain fatty acid accumulation, and wax ester production.
