Method for producing polyunsaturated fatty acids in transgenic organisms to contain at least a delta-9 elongase and desaturase Delta - 8 - and if necessary alsoA Delta - desaturase; nucleotide sequences of delta - desaturase - 8

摘要

The present Invention relates to an improved process for the specific production of polyunsaturated fatty acids w-3 and w-6 and conduct Production trigliceriWith an increased content of unsaturated fatty acids in particular Fatty Acids w-3 and w-6 having at least two double Bonds and a chain length of 20 or 22 Atoms of CarboNot.The Invention relates to the production of a transgenic organism, preferably a transgenic plant or microorganism trangenico, which has an increased content of Fatty AcidsOils, Lipids containing C20 fatty acids - C22 - A5 with a double Bond, 7.8,10 respectively due to the expression of a desacurasa A8 and A9 elongase organisms such as plants or Algae Isochrysis galbana preferably as Euglena gracilis.The Invention also relates to a process for the production of polyunsaturated fatty acids such as arachidonic acid icosapentanoico,Dosapentanoico or dosahexanoico through coexpression of - 8 - 9 desaturase, a - to - 5 - elongase and desaturase in organisms such as plants or microorganisms.
