  • Patent number: 6054566
    Abstract: The present invention relates to a recombinant viral nucleic acid selected from a (+) sense, single stranded RNA virus possessing a native subgenomic promoter encoding for a first viral subgenomic promoter, a nucleic acid sequence that codes for a viral coat protein whose transcription is regulated by the first viral subgenomic promoter, a second viral subgenomic promoter and a second nucleic acid sequence whose transcription is regulated by the second viral subgenomic promoter. The first and second viral subgenomic promoters of the recombinant viral nucleic acid do not have homologous sequences relative to each other. The recombinant viral nucleic acid provides the particular adivantage that it systemically transcribes the second nucleic acid in the host. Host organisms encompassed by the present invention include procaryotes and eucaryotes, particularly animals and plants.

  • Patent number: 6048707
    Abstract: Methods and kits for structurally analyzing carbohydrate molecules are taught. Carbohydrates for analysis are derivatized (preferably methylated) and then hydrolyzed into constituent monosaccharides. The derivatized monosaccharides are then labeled by a fluorophore and separated from one another by electrophoresis. The identity of derivatized monosaccharides is established by comparison with identification standards. The electrophoresis separation patterns may be visualized by a charged coupled device camera or photographically.

  • Patent number: 6037456
    Abstract: The present invention features a method for isolating and purifying viruses, proteins and peptides of interest from a plant host which is applicable on a large scale. Moreover, the present invention provides a more efficient method for isolating viruses, proteins and peptides of interest than those methods described in the prior art. In general, the present method of isolating viruses, proteins and peptides of interest comprises the steps of homogenizing a plant to produce a green juice, adjusting the pH of and heating the green juice, separating the target species, either virus or protein/peptide, from other components of the green juice by one or more cycles of centrifugation, resuspenion, and ultrafiltration, and finally purifying virus particles by such procedure as PEG-precipitation or purifying proteins and peptides by such procedures as chromatography and/or salt precipitation.

  • Patent number: 5965794
    Abstract: A novel method of over expressing genes in plants is provided. This method is based on the RNA amplification properties of plus strand RNA viruses of plants. A chimeric multicistronic gene is constructed containing a plant promoter, viral replication origins, a viral movement protein gene, and one or more foreign genes under control of viral subgenomic promoters. Plants containing one or more of these recombinant RNA transcripts are inoculated with helper virus. In the presence of helper virus recombinant transcripts are replicated producing high levels of foreign gene RNA.Sequences are provided for the high level expression of the enzyme chloramphenicol acetyltransferase in tobacco plants by replicon RNA amplification with helper viruses and movement protein genes derived from the tobamovirus group.

  • Patent number: 5934012
    Abstract: This invention relates to a submerged fermentation process for producing high biomass levels of mushrooms mycelia in liquid media suitable for semi-continuous or continuous mushroom spawn production. The process provides a sterile, log phase inoculum for a solid substrate that, when based on biomass, exceeds normal inoculation levels by several thousand fold mycelia substrate production. The liquid inoculum so produced can be aseptically transferred to bulk sterilizer to inoculate a sterilizer grain or sawdust substrate for commercial mushroom production. The liquid inoculum may also be inoculated directly onto the mushroom compost. This invention further relates to microcapsules used to enhance the fermentation process and the equipment used to conduct such process.
