Patent ID: 7893320

Claim:
A process for the production of compounds in transgenic plant cells, plants or parts thereof, wherein said compounds are comprised of general Formula I: wherein R 1 ═—OH, coenzyme A (thioester), phosphatidylcholine, phosphatidylethanolamine, phoshatidylglycerol, diphosphatidylglycerol, phosphatidylserine, phosphadatidylinositol, sphingolipid, glycoshingolipid or a radical of general Formula II: wherein R 2 =saturated or unsaturated C 20 -alkylcarbonyl-; and R 3 =saturated or unsaturated C 20 -alkylcarbonyl-; wherein n=3, 4 or 6, m=3, 4 or 5; and p=0 or 3, and said compounds comprise at least 1% by weight of the total fatty acid content of said transgenic plants, which process comprises the following steps: a) introducing, into a plant cell, plant or part thereof: i) at least one first nucleic acid sequence which encodes a polypeptide with an Δ6-desaturase activity; ii) at least one second nucleic acid sequence which encodes a polypeptide with a Δ6-elongase activity; and iii) a third nucleic acid sequence which encodes a polypeptide with a Δ5-desaturase activity; and b) growing and harvesting the transgenic plant cell, plant or part thereof, wherein said nucleic acid sequences are obtained from Phaeodactylum tricornutum or Physcomitrella patens , and wherein the at least one first nucleic acid sequence comprises the sequence of SEQ ID NO: 13, a nucleic acid sequence encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 14, or a nucleic acid sequence encoding a polypeptide having at least 90% homology with the amino acid sequence of SEQ ID NO: 14 and having essentially the same enzymatic activity.
