  • Publication number: 20150230474
    Abstract: A method of treating a plant growth medium comprising applying a glyphosate pesticide to the plant growth medium. The treatment may prevent, inhibit, reduce and/or treat clubroot disease, caused by infection with Plasmodiophora brassicae, in one or more plants grown in the plant growth medium. Further provided is use of a glyphosate pesticide to treat a plant growth medium in order to prevent or treat clubroot disease in one or more plants grown in the plant growth medium. Additionally provided is a glyphosate pesticide for use to treat a plant growth medium in order to prevent or treat clubroot disease in one or more plants grown in the plant growth medium. Also provided is a method of treating a piece of agricultural equipment with a glyphosate pesticide.

  • Patent number: 7511189
    Abstract: The present invention relates to the isolation, purification, characterization and use of the plant diacylglycerol acyltransferase (DGAT) gene and genetic products. The invention includes isolated and purified DGAT DNA and relates to methods of regulating seed oil content, the ratio of diacylglycerol/triacylglycerol proportions in the seed oil, fatty acid synthesis, seed oil acryl composition, seed size/weight and carbon flux into other seed components, 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: 7112724
    Abstract: The invention provides a method for genetically transforming a plant so that it expresses a glycerol-3-phosphate dehydrogenase that is feedback-defective. The feedback-defective enzyme raises levels of glycerol and glycerol-3-phosphate in comparison to the wild-type, leading to increased osmotic stress tolerance, and altered fatty acid content in glycerolipids.

  • Patent number: 7015373
    Abstract: The present invention relates to the isolation, purification, characterization and use of the plant diacylglycerol acyltransferase, DGAT, gene and associated gene products. The invention includes isolated and purified DGAT cDNA (SEQ ID NO: 1) and a plant diacylglycerol acyltransferase gene (SEQ ID NO: 3) and homologues thereof from the Brassicaceae, such as Arabidopsis thaliana. Methods of using the DGAT DNA to regulate seed oil content, the ratio of diacylglycerol/triacylglycerol proportions in the seed oil, fatty acid synthesis, seed oil acyl composition, seed size/weight and carbon flux into other seed components are also included. Methods of producing transgenic plants, plant tissues and plant seeds having genomes including DGAT genes, and the resultant transgenic plants, plant tissues and plant seeds are also included.
