    Abstract: The present invention generally is concerned with the modification of plant lipids containing PUFAs. In this context, the invention is particularly concerned with plants and plant materials for such modifications, wherein the plants preferably are oilseed plants. Regarding plant parts, the invention is particularly concerned with seeds of such plants and preferably seeds of oilseed plants. The invention is also concerned with plant positions obtainable or obtained by the modification method of the invention, and with full stuff of feedstuff comprising such liquid compositions.

    Abstract: The present invention relates to methods for the conversion of the substrate specificity of desaturases. Specifically, the present invention pertains to a method for the conversion of the substrate specificity of a Δ5 and/or Δ6 desaturase to the substrate specificity of a Δ4 desaturase, the method comprising: identifying regions and/or amino acid residues which control the substrate specificity of (i) the Δ5 and/or Δ6 desaturase and (ii) the Δ4 desaturase; and replacing in the amino acid sequence of the mentioned Δ5 and/or Δ6 desaturase, the regions and/or amino acid residues which control the substrate specificity of the Δ5 and/or Δ6 desaturase, by the corresponding regions and/or amino acid residues which control the substrate specificity of the Δ4 desaturase, thereby converting the substrate specificity of the Δ5 and/or Δ6 desaturase to the substrate specificity of the Δ4 desaturase. The present invention further concerns a method for the conversion of the substrate specificity of a Δ4 desaturase to the substrate specificity of a Δ5 and/or Δ6 desaturase, the method comprising: identifying regions and/or amino acid residues which control the substrate specificity of (i) the Δ4 desaturase and (ii) the Δ5 and/or Δ6 desaturase; and replacing in the amino acid sequence of the indicated Δ4 desaturase, the regions and/or amino acid residues which control the substrate specificity of the Δ4 desaturase, by the corresponding regions and/or amino acid residues which control the substrate specificity of the Δ5 and/or Δ6 desaturase, thereby converting the substrate specificity of the Δ4 desaturase to the substrate specificity of the Δ5 and/or Δ6 desaturase. In addition, the invention encompasses desaturases with converted substrate specificity.

    Abstract: The invention provides nucleic acid molecules which encodes a novel fatty acid desaturase, KCS, KCR and/or LACS from Thraustochytrium aureum and Sphaeroforma arctica. The invention also provides recombinant expression vectors containing said nucleic acid molecules, host cells into which the expression vectors have been introduced, and methods for large-scale production of long chain polyunsaturated fatty acids (LCPUFAs), e.g., ARA, EPA and DHA and for screening for delta-4 desaturases.

    Abstract: Assay method, comprising providing a plant capable of expressing a delta-12 desaturase, wherein said delta-12 desaturase has at least 50% total amino acid sequence identity to at least one of the sequences SEQ ID NO. 328 to 336, and/or at least 59% total amino acid sequence similarity to at least one of the sequences SEQ ID NO. 328 to 336, and wherein the plant is also capable of expressing at least one or more enzymes of unsaturated fatty acid metabolism, of which enzymes at least one is capable of using linoleic acid as a substrate, and of which enzymes at least one is supposedly connected to a plant metabolic property, growing the plant, and measuring said plant metabolic property for said plant.
