The invention relates to a novel elongase gene comprising the sequence SEQ ID NO:1 or the homologues, derivatives or analogues thereof, to a gene construct comprising said gene or the homologues, derivatives or analogues thereof, and to the use of the same. The invention also relates to vectors or organisms having an elongase gene comprising the sequence SEQ ID NO:1 or the homologues, derivatives or analogues thereof. The invention further relates to a method for producing polyunsaturated fatty acids and to a method for introducing DNA into organisms which produce large quantities of oils, especially oils having a high unsaturated fatty acid content. Disclosed is also 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. |
