摘要： The present invention relates to the isolation of a second omega-3 fatty acid desaturase (FAD3) gene in flax (Linum usitatissimum) and its promoter region, as well as the identification of FAD3 mutant alleles, and the development of markers for wild type and mutated alleles. The FAD3 genes encode the enzymes which control omega-3 fatty acid desaturation and, thus, the levels of linolenic acid (18:3(n-3)). Accordingly, the molecules of the present invention can be utilized, for example, to develop markers for the mutations in flax FAD3 genes and for seed-specific modification of fatty acid and protein compositions in plant seeds.

摘要： The present invention is directed to promoters of flax conlinin and ω-3 desaturase genes. The promoters guide high levels of the expression exclusively in flax developing seeds. This specific expression pattern concomitant with the biosynthesis of storage lipids and proteins make these promoters particularly useful for seed-specific modification of fatty acid and protein compositions in plant seeds.

摘要： 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.
