NOVEL PLANT ACYLTRANSFERASES SPECIFIC FOR LONG-CHAINED, MULTIPLY UNSATURATED FATTY ACIDS

摘要

The invention relates to a method for the production of long-chained, multiply unsaturated fatty acids in an organism, wherein nucleic acids coding for polypeptide with acyltransferase activity are introduced into the organism. Said nucleic acid sequences can be advantageously expressed in the organism, optionally together with other nucleic acid sequences coding for polypeptides of the biosynthesis of the fatty acid or lipid metabolism. The invention also relates to a method for the production of oils and/or triacylglycerides with an increased content of long-chained, multiply unsaturated fatty acids. The invention further relates to the nucleic acid sequences, nucleic acids constructs vectors and organisms containing the inventive nucleic acid sequences, vectors containing the nucleic acid sequences and/or nucleic acid constructs and transgenic organisms containing the above-mentioned nucleic acid sequences, nucleic acid constructs and/or vectors. The invention additionally relates to oils, lipids and/or fatty acids produced according to the inventive method and to the utilization thereof.
