"ISOLATED NUCLEIC ACID, ISOLATED NUCLEIC ACID SEQUENCES, GENE CONSTRUCTION, VECTOR, ORGANISM, PROCESS FOR THE PRODUCTION OF PUFAS, OIL, LIPID OR FATOID DIOXES, FATOID DIOCIDE, FRACTION AND, USE OF THE SAME ". The invention relates to a novel elongase gene comprising the sequence SEQ ID NO: 1 or homologs, derivatives or analogs thereof, to a gene construct comprising said gene or homologues, derivatives and analogs and to the use thereof. The invention also relates to vectors or organisms having an elongase gene comprising the sequence SEQ ID NO: 1 or their homologues, derivatives or analogs. The invention further relates to a method for producing polyunsaturated fatty acids and a method for introducing DNA into organisms that produce large amounts of oils especially oils that have a high content of unsaturated fatty acids. Also disclosed is an oil and / or a fatty acid composition having a higher content of polyunsaturated fatty acids comprising at least two double bonds and / or a triacylglycerine composition having a higher content of polyunsaturated fatty acids comprising at least two double bonds.
