Provided is ω3 desaturase having high enzymatic activity even at normal temperature. A polypeptide which consists of an amino acid sequence having an identity of 80% or more with the amino acid sequence represented by SEQ ID NO: 2 and has ω3 desaturation activity on C20 fatty acid, and a gene thereof.

An identified 90 bp sequence insertion in the GB0331 genome disrupts the coding sequence of the FAD2-1D gene near the 3′ end of the protein coding region. This sequence is not found in reference genomes of other Gossypium species. This DNA segment can be used to track the high oleic fad-2-1D mutant allele for introgression into cotton varieties such as Pima and upland cotton varieties. This enables a non-GMO strategy to elevate the oleic acid content of commercial cottonseed oil.

The present invention relates generally to the field of molecular biology and concerns increasing the tocopherol content of a plant relative to a control plant, comprising expressing in a plant at least one polynucleotide encoding a delta-12-desaturase, at least one polynucleotide encoding a delta-6-desaturase, at least one polynucleotide encoding a delta-6-elongase, and at least one polynucleotide encoding a delta-5-desaturase. The present invention also relates to methods for the manufacture of oil, fatty acid- or lipids-containing compositions, and to such oils and lipids as such.

The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids. In particular, the present invention provides ω3 destaurases, Δ5 elongases and Δ6 desaturases with novel activities. Also provided are methods and DNA constructs for transiently and/or stably transforming cells, particularly plant cells, with multiple genes.

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.

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.

The present disclosure provides systems and methods for increasing production of an alkaloid product through the epimerization of a (S)-1-benzylisoquinoline alkaloid to a (R)-1-benyzlisoquinoline alkaloid via an engineered epimerase in an engineered host cell. A (S)-1-benzylisoquinoline alkaloid is contacted with said engineered epimerase. Contacting said (S)-1-benzylisoquinoline alkaloid with said engineered epimerase converts said (S)-1-benzylisoquinoline alkaloid to said (R)-1-benzylisoquinoline alkaloid.

The present invention relates to a process for dyeing textiles, in particular for dyeing textiles using enzymes. The present invention also relates to a method for producing leuco indigo and/or leuco forms of indigo derivatives. The present invention further refers to textiles obtainable through said process, to an apparatus comprising a reactor containing enzymes, and to a microbial flavin-containing monooxygenase.

Isolated nucleotide sequences mutated by insertion encoding a truncated sunflower oleate desaturase protein, truncated protein, methods, procedures and uses. The isolated nucleotide sequences comprise an insertion that includes a stop codon, and wherein the sequences encode a truncated sunflower oleate desaturase protein. The truncated sunflower oleate desaturase protein may be for example the sequence shown in SEQ ID No: 1 or SEQ ID No: 2.

A method for producing a microbial oil includes steps of: genetically modifying a labyrinthulid by disrupting and/or silencing a gene, or by transforming another gene in addition to the disruption and/or gene silencing of the gene, and culturing the labyrinthulid, such that a fatty acid composition accumulated in the labyrinthulid comprises an increased EPA content; and collecting the microbial oil having the increased EPA content from the labyrinthulid. The labyrinthulid before the modification is selected from (A) a labyrinthulid belonging to the genus Parietichytrium or genus Schizochytrium and having very weak or no activity of producing PUFAs via a PUFA-PKS pathway; and (B) a labyrinthulid belonging to the genus Thraustochytrium in which a host PUFA-PKS gene is disrupted or silenced to a very weak level. The increased EPA content is preferably not less than 11.5% of a total fatty acid composition.
