FAE1 — Brassica oleracea

Summary

BoFAE1 (BOLC102_C03P092110.1) on cabbage chromosome 3 encodes a 3-ketoacyl-CoA synthase, a member of the FAE1-type polyketide synthase family with acyltransferase activity, and is annotated for naringenin-chalcone synthase and biphenyl synthase activities. The gene is associated with very-long-chain fatty acid biosynthesis and metabolism, fatty acid elongation, and lipogenesis, as well as polyketide and flavonoid anabolism. It is linked to seed oil content and composition, eicosenoic acid content, and trichome development. The encoded protein localises to the endoplasmic reticulum and membrane. Studies of related genes in other species link the family to erucic acid content, seed very-long-chain fatty acid accumulation, and wax ester accumulation, with further associations to seed weight, plant height, drought tolerance, and grain yield.
