  • Publication number: 20050150010
    Abstract: Methods of genetically manipulating biology active 4?-O-methylated isoflavonoids have been found based upon the regiospecifity of isoflavone 7-OMT in vivo. Upon transformation and expression of an isoflavonoid O-methyltransferase gene, up-regulation of IOMT in the transgenic plants can be used to increase the accumulation of 4?-O-methylated isoflavonoid phytolalexins, providing for increased disease resistance to the plant. Similar methods can be used to increase accumulation of 4?-O-methylated isoflavonoid nutraceuticals in plants. For down-regulation of IOMT in plants that naturally make 4?O-isoflavonoid phytoalexins and 4?-O-methylated isoflavonoid nutraceuticals, IOMT gene sequences can be transformed in the antisense orientation.

  • Publication number: 20040128711
    Abstract: The invention provides method and compositions for the modulation of flavanone and/or isoflavone production in plants. The methods of the invention allow creation of plants having novel phenotypes. Increased expression of isoflavones in particular in plants may be used to increase the nutritional value of food plants for both human and animal consumption. The invention overcomes limitations of the prior art which prevented accumulation of high levels of isoflavones in plants.

  • Publication number: 20040119385
    Abstract: A lateral file having a cabinet structure which provides improved rigidity against racking, including an improved upright boxlike housing having an improved base associated therewith. The housing has opposed sidewall structures which are defined by identical one-piece monolithic structures each having a generally planar and upright exterior side wall with a pair of channel-like uprights fixed to an inside surface thereof and extending vertically along the exterior side wall adjacent opposite edges thereof. The upright channels and the exterior side wall are formed as a monolithic one-piece structure from a monolithic piece of sheet steel, such as by roll forming. The sidewall structure is generally symmetrical about a vertically extending centerline so that identical sidewall structures can define both the right and left sides of the housing.

  • Patent number: 6748997
    Abstract: An upright connector or support post usable in a space-dividing wall panel system formed from serially connected panel assemblies. The post includes a plurality of openings disposed in vertically spaced relation with one another which receive load-bearing elements such as hangers or hooks typically associated with furniture components. Dimples or deformations extend transversely along the upper and lower edges of the openings and provide increased strength at the attachment points along the post.

  • Publication number: 20040093632
    Abstract: The invention provides method and compositions for the modulation of condensed tannin production in plants. The methods of the invention allow creation of plants having novel phenotypes. Increased expression of condensed tannins in plants may be used to increase the nutritional value of food plants for both human and animal consumption. Increased condensed tannin content also reduces the potential for bloat in animals fed certain forage plants low in condensed tannin content. The invention may also be used to modify plant pigmentation.

  • Publication number: 20040049802
    Abstract: Methods for transforming forage legumes or woody plants with a DNA construct comprising at least one open reading frame encoding for a caffeoyl CoA 3-O-methyltransferase enzyme or a Medicago sativa caffeic acid 3-O-methyltransferase enzyme or a fragment thereof in either a sense or antisense orientation under a lignification-associated tissue specific promoter have been found, resulting in the down-regulation of the corresponding homologous gene either through antisense inhibition or sense suppression, as well as reduced lignin content and modified lignin composition in the transgenic plants. The expression of the caffeoyl CoA 3-O-methyltransferase transgene produces an increased syringyl lignin to guaiacyl lignin ratio in the transformed plant, and greatly improved forage digestibility.

  • Publication number: 20040002105
    Abstract: The invention provides methods for the isolation of plant genes and their regulatory sequences involved in the biosynthesis of triterpene saponins. Also provided by the invention are genes involved in the biosynthesis of triterpenes, including squalene synthase, squalene epoxidase and &bgr;-amyrin synthase from Medicago truncatula. The identification of triterpene biosynthesis genes allows genetic modification of the content and composition of triterpene saponins in plants for crop improvement and the development of drugs, nutriceuticals and functional foods.

  • Patent number: 6631551
    Abstract: A process for forming stable integrated resistors (14) and capacitors (28) on organic substrates (12). The resistors (14) and capacitors (28) are capable of a wide range of resistance and capacitance values, yet can be processed in a manner that does not detrimentally effect the organic substrate (12) or entail complicated processing. The method generally entails the use of thick-film materials usually of the types used to form resistors and capacitors on ceramic substrates. The thick-film materials are applied to an electrically-conductive foil (20) and then heated to bond the thick-film material to the foil (20) and form a solid resistive or capacitive mass (16/30). The foil (20) is then laminated to an organic substrate (12), such that the resistive/capacitive mass (16/30) is attached to and preferably embedded in the organic substrate (12).

  • Patent number: 6573432
    Abstract: A method for determining gene expression in transgenic plants is disclosed. This method includes providing expression vectors having the PAP1 or PAP2 gene linked to an expressed gene of interest. If the expression vector is activated, the PAP1 or PAP2 genes confer a purple pigmentation to the transgenic plant. Thus, plants that have been successfully transformed are easily identifiable by visual inspection.
