  • Publication number: 20060040342
    Abstract: The present invention encompasses isolated gene regulatory elements and gene transcription terminators that are differentially expressed in a native fungus exhibiting a first morphology relative to the native fungus exhibiting a second morphology. The invention also encompasses a method of utilizing a fungus for protein or chemical production. A transformed fungus is produced by transforming a fungus with a recombinant polynucleotide molecule. The recombinant polynucleotide molecule contains an isolated polynucleotide sequence linked operably to another molecule comprising a coding region of a gene of interest. The gene regulatory element and gene transcription terminator may temporally and spatially regulate expression of particular genes for optimum production of compounds of interest in a transgenic fungus.

  • Publication number: 20050060775
    Abstract: The invention includes methods for production of a polypeptide having factor VIII activity by introduction of a polynucleotide construct into a plant cell. The construct includes an encoding sequence for a polypeptide of coagulation factor VIII or a functional variant thereof. The plant cell is cultured or regenerated into a plant and the polypeptide or functional variant of factor VIII is expressed therein. The invention also includes vectors, plant cells, plant tissues, plants and seeds containing a polynucleotide sequence encoding a functional variant of human coagulation factor VIII. The invention further includes a recombinant DNA molecule having a promoter which is functional in plants operably linked to a coding sequence which codes for a polynucleotide having coagulation factor VIII activity.

  • Publication number: 20050005324
    Abstract: There are disclosed novel pin1 gene promoter isoforms and amt gene promoter isoforms. The promoters and their functional elements may be used independently or in combination with one or more enhancer elements to increase or otherwise manipulate gene expression. The promoters disclosed may be used in Controlled Environment Agriculture for heterologous protein production. Also disclosed are methods for using the promoter and promoter elements of the instant invention, as well as vectors and transgenic plants comprising the same.

  • Patent number: 6783978
    Abstract: The promoter of the ribosomal protein gene L25 is operably linked to a structural gene. This chimeric gene is placed in an expression vector. The expression vector containing the chimeric gene is used to transform plants cells and plants. Seeds are obtained from the transformed plants. A product, such as a protein, encoded by the structural gene is isolated from the transformed plant cells and plants.

  • Publication number: 20030215950
    Abstract: The invention includes isolated polynucleotide molecules that are differentially expressed in a native fungus exhibiting a first morphology relative to the native fungus exhibiting a second morphology. The invention includes a method of enhancing a bioprocess utilizing a fungus. A transformed fungus is produced by transforming a fungus with a recombinant polynucleotide molecule. The recombinant polynucleotide molecule contains an isolated polynucleotide sequence linked operably to a promoter. The polynucleotide sequence is expressed to promote a first morphology. The first morphology of the transformed fungus enhances a bioprocess relative to the bioprocess utilizing a second morphology.

  • Publication number: 20030073828
    Abstract: This invention provides transgenic plants that have increased or decreased activity of uridine 5′-diphospho-galactose 4-epimerase. Controlling the level of uridine 5′-diphospho-galactose 4-epimerase in the transgenic plants is used to regulate the nutritional profile of the plant by controlling the use of glucose and/or galactose. An isolated polynucleotide coding for the potato uridine 5′-diphospho-galactose 4-epimerase protein, its antisense equivalent and the nucleic acid sequence of potato uridine 5′-diphospho-galactose 4-epimerase are also provided. The present invention also provides a method for reducing the activity of uridine 5′-diphospho-galactose 4-epimerase activity in plants. The present invention also provides a method of producing bulk quantities of uridine 5′-diphospho-galactose 4-epimerase enzyme in transgenic plants.

  • Publication number: 20020046418
    Abstract: An integrated system for commercial production of a heterologous protein in transgenic plants under conditions of controlled environment agriculture (CEA) is provided. CEA comprises growth of plants under defined environmental conditions, preferably in a greenhouse, to optimize growth of the transgenic plant as well as expression of the gene encoding the heterologous protein. The transgenic plants used in the present invention are transformed with an expression vector comprising a CEA promoter operably linked to a gene encoding the heterologous protein of interest, wherein the CEA promoter is selected to maximize heterologous protein production under the defined environmental conditions of CEA.

  • Patent number: 6355864
    Abstract: Synergistically functional, yet separable, cis-acting enhancer elements from the rpL34 promoter are disclosed. These enhancer elements of the instant invention may be used in combination with a plurality of promoters to increase gene expression without affecting the intrinsic specificity of the promoters. Also disclosed are methods for using the enhancer elements of the instant invention as well as vectors and transgenic plants comprising the enhancer elements.
