  • Patent number: 6703539
    Abstract: The present invention provides a method of making a genetically transformed plant which has an altered content of at least one product of a secondary metabolic pathway. The method consists of introducing into a plant cell capable of being transformed and regenerated to a whole plant a DNA expression cassette. The expression cassette includes DNA sequences required for transformation and selection in plant cells. It also includes a DNA sequence that, under the control of a promoter active in plant cells, encodes a protein capable of modifying the utilization of a substrate in the secondary metabolic pathway. The substrate is not a primary metabolite of the group selected from glucose, amino acids, common fatty acids and nucleotides. A plant or plant tissues including seeds can then be recovered having an altered content of at least one product of the secondary metabolic pathway. The invention also provides for feed products derived from the plants and seeds obtained according to the method.

  • Patent number: 6501004
    Abstract: The sinapine content of seeds of Brassica napus, and other crucifera plants, and the resulting seed meal made therefrom, is reduced by transforming cells of the plants to incorporate an expressible exogenous CYP84 monooxygenase enzyme, particularly ferulate 5-hyroxylase (F5H:) enzyme, or an antisense equivalent thereof. This allows for the production of a seed meal that is commercially more valuable. Three specific nucleic acid sequences encoding the F5H polypeptide are disclosed, designated BNF5H1, BNF5H2 and BNF5H3, and genetic constructs produced. The antisense suppression of sinapine is preferred, which can reduce the sinapine content of seed meal by up to 40% compared to wild type or vector-only transformed plants.

  • Publication number: 20020192692
    Abstract: Probes and methods of using the probes to detect chromosomal rearrangements and/or deletions are provided. The methods utilize probes that are free of repeat sequences to provide greater selectivity and sensitivity; methods for producing such probes are also disclosed. The probe sets utilized in the detection methods are designed to hybridize to chromosomes at regions outside known breakpoints, instead of spanning the breakpoint as with conventional FISH methods, and, in some instances, are further designed to bind to regions located outside the genes involved in the rearrangement. Methods utilizing probe sets with two and four colors are also described, as are automated methods for analyzing rearrangements.

  • Patent number: 5639663
    Abstract: Genetic markers of this invention provide a biochemically assayable reporter activity and a conditionally selectable growth advantage. They comprise a first gene which encodes a product whose activity can be assdyed biochemically e.g., .beta.-glucuronidase, to a second gene which confers a conditional growth advantage such as antibiotic resistance in a transformed cell (e.g., neomycin phosphotransferase-II). The marker genes and their translational products are stable in cells. The genetic markers provide for the positive genetic selection and the biochemical and histochemical screening of transformed cells. They can be used as probes for identification and isolation of novel genetic regulatory elements, such as promoters, and the genes they regulate.

  • Patent number: 5454157
    Abstract: A disk drive having a hermetically sealed disk chamber capable of being filled with gas at pressures above ambient pressure with a specially designed connector assembly for use with the sealed chamber. Helium or nitrogen is injected into the sealed disk chamber. To decrease power consumption at high platter spin rates, the present invention advantageously utilizes a sealed disk chamber filled with helium to reduce tribological resistance forces associated with the surfaces of the spinning platters. Nitrogen is used to reduce oxidation of the disk platters. Special fixtures maintaining high position tolerance and connectors are designed to coupled the PC board controller of the disk drive unit to the components of the disk drive within the sealed disk chamber to eliminate connecting flexcircuits from the junction of the hermetically sealed chamber.

  • Patent number: 5102645
    Abstract: The present invention is directed to a method for producing high purity carbon monoxide. In the method, a hydrocarbon feed stock and import carbon dioxide are introduced into a reaction system containing a primary reformer and a secondary reformer. The hydrocarbon feed stock, import carbon monoxide and recycle carbon monoxide are passed through the primary reformer while being heated to a temperature sufficient to reform the feed stock into a first carbon monoxide reaction product. The first reaction product and oxygen are fed into the secondary reformer. The first reaction product is reacted in the secondary reformer in an autothermal reaction to provide a second carbon monoxide reaction product having a lower hydrocarbon level than the first reaction product. The second reaction product is removed from the secondary reformer at a second predetermined temperature and a high purity carbon monoxide is recovered from the second reaction product without the use of cryogenic separation techniques.
