Abstract
The present invention relates to a method for increasing the content of polyunsaturated long-chain fatty acids in an organism by introducing nucleic acids coding for polypeptides or proteins exhibiting a phospholipase, ketoacyl-CoA reductase and/or dehydratase activity. The present invention also provides nucleic acid sequences coding for polypeptides with enzyme activities of a phospholipase, ketoacyl-CoA reductase and/or dehydratase, and nucleic acid constructs, vectors and organisms containing the nucleic acid sequences according to the present invention. A further part of the present invention relates to oils, lipids and/or fatty acids produced according to the method of the present invention and the use thereof. Furthermore, the present invention relates to unsaturated fatty acids and triglycerides having an increased content of unsaturated fatty acids and the use thereof.
