  • Publication number: 20250179515
    Abstract: The present invention refers to a plant or plant part comprising a polynucleotide encoding an herbicide tolerant IAA2 polypeptide having a deleted or disrupted degron tail region, the expression of said polynucleotide confers to the plant or plant part tolerance to synthetic auxin herbicides, such as 2,4-D. The present invention relates to methods and plants and that have a deleted or disrupted degron tail region of the IAA2 protein obtained by gene editing, transformation, mutagenesis, breeding, and the like.

  • Patent number: 8702458
    Abstract: The invention provides a powered water sports board (10) which includes a motor (16) and a power supply (18), both of which are mounted inside a cavity (20) formed inside an elongate buoyant body (12) of the powered water sports board, and a propeller (36) which is capable of being driven by the motor (16) and which is housed inside a fin (14) of the elongate buoyant body (12) thereby to shield the propeller.

  • Patent number: 8263384
    Abstract: Novel organisms, including DNA construct host cell combinations, are disclosed. The organisms comprise a transcription unit (e.g. operon) comprising DNA sequences encoding for enzymes which promote the supply of single carbon units for the conversion of dUMP to dTMP. Examples include: dihydrofolate reductase genes e.g. T4 frd; Serine Hydroxymethyltransferase genes e.g. glyA; 3-phosphoglycerate dehydrogenase genes e.g. serA; and THF synthase genes e.g. ADE3. The organisms are used in a biological method of producing thymidine with significantly reduced levels of uridine.

  • Publication number: 20050269002
    Abstract: A method of producing an ammonium nitrate blasting agent and such an agent. The method comprises the steps of first combining together a crystal habit modifier with an aqueous solution of ammonium nitrate. Using the mixture of the crystal habit modifier and the ammonium nitrate solution, ammonium nitrate crystals are formed having a particle size of about 1 to about 500 microns. The ammonium nitrate crystals are then combined with an organic carbonaceous fuel at a ratio such that the organic carbonaceous fuel is from about 2 to about 10 percent by weight of the blasting agent.

  • Publication number: 20020028925
    Abstract: The present invention relates to a recombinant herpes simplex virus (HSV) viral vector genome which has substantially lost its transducing properties as a result of a DNA sequence change in the gene coding for Vmw65 protein and also comprises an expressable heterologous gene inserted into a region of the HSV genome which is non-essential for the culture of the virus, the gene being under the control of the immediate early (IE1) gene enhancer of cytomegalovirus (CMV) and to the use of the recombinant HSV genome in therapy and vaccination.
