  • Patent number: 6392121
    Abstract: A gene amplification system based on plant viral genetic elements dramatically increases foreign protein production in plants. A safer and more economical production system for vaccines and antibodies in recombinant plants grown using agricultural practice is described. The high-level expression system uses the replicative process of a plant mastrevirus, exemplified by bean yellow dwarf virus (BeYDV). The expression system is preferably inducible to avoid interference with plant growth and development. Developmental cues, such as fruit ripening, are employed to trigger expression of the foreign protein using a tissue-specific promoter. A single, stably integrated expression cassette for foreign protein is replicated extrachromosomally in ripening fruit, forming hundreds of transcriptionally competent copies. Preferred plant hosts include tomato as a model system and soybean for production of large quantities of protein at high total protein levels.

  • Patent number: 6177613
    Abstract: The present invention provides a composition and method for regulating expression of heterologous nucleotide sequences in a plant. The composition is a novel nucleic acid sequence for a seed-preferred promoter. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequence is also provided. The method comprises transforming a plant cell to contain a heterologous nucleotide sequence operably linked to the seed-preferred promoter of the present invention and regenerating a stably transformed plant from the transformed plant cell.

  • Patent number: 6100092
    Abstract: Products and methods for amplifying target nucleic acids using cells derived from plants are disclosed. The products include nucleic acids containing a plant active Amplification Promoting Sequence (APS) and the methods exploit these products in amplifying target nucleic acids. Also disclosed are methods for amplifying target nucleic acids that express an encoded product, and the recovery of that expression product. The methods of the invention minimize operator intervention and exploit solar energy and the minimal nutrient needs of photoautotrophic organisms to provide inexpensive and indefinitely sustainable methods for producing a variety of amplified target nucleic acids and encoded products such as polypeptides.

  • Patent number: 6100446
    Abstract: The disclosure relates to the production and the use, by genetic engineering, of plasmids and bacterial strains containing, on a short, precisely characterizable DNA segment, the gene tfdA or a gene almost identical to tfdA.The novel plasmids and microorganisms are suitable for the production of 2,4-D (2,4-dichlorophenoxyacetic acid)-monooxygenase, and as starting materials for the transfer, by genetic engineering of the 2,4-D-degrading property of this enzyme to various organisms.

  • Patent number: 6096547
    Abstract: Constructs are provided for expression of physiologically active mammalian proteins in plant cells, either in culture or under cultivation. The constructs provide a promoter functional in a plant host, a structural gene coding for mammalian protein and a terminator functional in a plant host. The construct is introduced into a plant cell to become integrated into the plant genome for expression in the plant cells or plants. The plant cells may be harvested and the mammalian protein isolated in physiologically active form.

  • Patent number: 6093554
    Abstract: The invention relates to genetic manipulations of eukaryotic organisms, with recombinant DNA comprising RNA virus derived sequences for protecting such organisms against RNA viruses or enabling inducible or tissue-specific production of foreign proteins/peptides or RNAs. One embodiment of the recombinant DNA according to the invention comprises recombinant DNA, comprising two, 12-250 base pair long, inverted repeat nucleotide sequences with therebetween at least one nucleotide sequence which is derived from RNA virus which for its replication is dependent upon a viral RNA/RNA polymerase, said RNA virus derived sequence comprising at least cis elements for replication but no gene that codes for viral RNA/RNA polymerase and no gene that codes for viral coat protein. The invention also relates to eukaryotic or prokaryotic cells or organisms which incorporate the recombinant DNA according to the invention.
