    Abstract: The present invention relates to mutant delta-8 desaturase genes, which have the ability to convert eicosadienoic acid [20:2 omega-6, EDA] to dihomo-γ-linolenic acid [20:3, DGLA] and/or eicosatrienoic acid [20:3 omega-3, ETrA] to eicosatetraenoic acid [20:3 omega-3, ETA]. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding delta-8 desaturase along with methods of making long-chain polyunsaturated fatty acids (PUFAs) using these mutant delta-8 desaturases in plants and oleaginous yeast are disclosed.

    Abstract: The present invention relates to fungal Δ-15 fatty acid desaturases that are able to catalyze the conversion of linoleic acid (18:2, LA) to alpha-linolenic acid (18:3, ALA). Nucleic acid sequences encoding the desaturases, nucleic acid sequences which hybridize thereto, DNA constructs comprising the desaturase genes, and recombinant host plants and microorganisms expressing increased levels of the desaturases are described. Methods of increasing production of specific omega-3 and omega-6 fatty acids by over-expression of the Δ-15 fatty acid desaturases are also described herein.
