  • Patent number: 9410160
    Abstract: The present invention relates to the isolation, purification, characterization and use of the plant Snf1-related protein kinase (SnRK) gene and genetic products. The invention includes isolated and purified SnRK DNA and relates to methods of regulating water loss and plant drought tolerance, sucrose content, starch content, seed oil content, fatty acid synthesis, seed oil acyl composition, seed size/weight, resistance/tolerance to biotic stresses, increased root biomass, and/or carbon flux into other seed components, plant, using the gene, and to tissues and plants transformed with the gene. The invention also relates to transgenic plants, plant tissues and plant seeds having a genome containing an introduced DNA sequence of the invention, and a method of producing such plants and plant seeds.

  • Patent number: 9228175
    Abstract: Described nucleic acid molecules (and corresponding peptides) encode lyso-phosphatidylcholine (LPC) acyltransferases. Over-expression of the LPC acyltransferases in a cell may lead to enhanced production of PUFA, or other unusual fatty acids, and/or to increased oil content in the cell.

  • Patent number: 8993034
    Abstract: The present disclosure relates to the isolation, purification, and characterization of a diacylglycerol acyltransferase 2 (DGAT2), and genes encoding DGAT2, from algae. DGAT2 can incorporate very long-chain polyunsaturated fatty acids into triacylglycerol more efficiently than DGAT1. The disclosure concerns methods of regulating seed oil content, fatty acid synthesis and fatty acid composition using the DGAT2 gene and to tissues and plants transformed with the gene. The disclosure also relates to transgenic plants, plant tissues and plant seeds having a genome containing an introduced DNA sequence of the disclosure, and a method of producing such plants and plant seeds.
