1. A process for production of compounds comprising one or more C18-, C20-, and/or C22-polyunsaturated fatty acids in a transgenic organism comprising:

  • a) introducing, into an organism, at least one nucleic acid sequence which encodes an ω

    -3-desaturase that is capable of desaturating C20- or C22-fatty acids, andb) culturing the organism under conditions which permits the production of one or more C18-, C20-, and/or C22-polyunsaturated fatty acids,wherein the ω

    -3-desaturase is encoded by a nucleic acid sequence comprising;

    i) the nucleic acid sequence of SEQ ID NO;

    1,ii) a nucleic acid sequence encoding the amino acid sequence of SEQ ID NO;

    2,iii) a nucleic acid sequence having at least 95% identity with the nucleic acid sequence of SEQ ID NO;

    1, oriv) a nucleic acid sequence encoding an amino acid sequence having at least 95% identity with the amino acid sequence of SEQ ID NO;
