Genomicfattyacid elongation 1 (FAE1) clones from high erucic acid (HEA)Brassica napus, Brassica rapaandBras-sicaoleracea, and lowerucicacid (LEA)B. , were amplifiedbyPCRand expressed inyeast cells under the control of the strong galactose-inducible promoter. As expected, yeast cells expressing theFAE1genes from HEA Brassicaspp. synthesized very long chain monounsaturated fatty acids that are not normally found in yeast, while fatty acid profiles of yeast cells expressing theFAE1gene from LEA B. napuswere identical to control yeast samples
