  • Patent number: 5728926
    Abstract: A process is described for producing hybrid seed using male-sterile plants created by employing molecular techniques to manipulate antisense DNA and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing antisense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.

  • Patent number: 5728817
    Abstract: A family of genes has been found in plants, said genes encoding a family of developmental proteins that have homologous structures to the mammalian QM genes. Recombinant molecules which include the QM genes in plants are useful to transform cells and regenerate plants that, as a result, have altered developmental pathways. Methods of producing male sterile plants use recombinant molecules containing either the QM sense genes or antesense genes with appropriate promoters.

  • Patent number: 5716820
    Abstract: Methods for identifying organisms capable of degrading fumonisin. Fumonisin can be incorporated into culture medium for selection of organisms resistant to fumonisin. Using this method, several organisms have been identified. These organisms can be used to isolate the enzyme and the gene responsible for conferring fumonisin-resistance. The gene can be cloned and inserted into a suitable expression vector so that the protein can be further characterized. Additionally, the DNA encoding for fumonisin-resistance can be used to transform plant cells normally susceptible to Fusarium infection. Plants can be regenerated from the transformed plant cells. In this way, a transgenic plant can be produced with the capability of degrading fumonisin.

  • Patent number: 5717129
    Abstract: A method of maintaining sterility in plants is disclosed. The method comprises genetic transformation of parental plant lines with a sterility gene that is genetically linked to a resistance gene which confers resistance to a selective agent, increasing the transgenic parental line and coating the seed of the increased transgenic parental line with a composition comprising the selective agent to which the resistance gene confers resistance. The resistance gene can be under the control of an inducible gene, or, alternatively, under the control of constitutive or tissue specific, including seed-specific, promoters.

  • Patent number: 5712107
    Abstract: The present invention provides methods of making paper utilizing glucans, produced by the glucosyltransferase C enzyme of the species Streptococcus mutans, instead of modified starches. The present glucans are functionally similar to the hydroxethyl modified starch and are particularly useful in the coating step of paper manufacture. The present glucans also exhibit thermoplastic properties and impart gloss to the paper during the coating step.

  • Patent number: 5710366
    Abstract: Sunflower plants, seeds capable of forming the same, and a novel endogenous vegetable oil derived from such sunflower seeds are provided. The plants have the ability to yield an endogenous vegetable oil wherein the levels of palmitic acid and oleic acid are provided in an atypical combination via genetic control. The concentration of palmitic acid in the endogenous oil constitutes at least 20 (e.g., approximately 20 to 45) percent by weight of the total fatty acid content, and the concentration of oleic acid in the oil constitutes at least 45 (e.g., approximately 45 to 65) percent by weight of the total fatty acid content in the absence of hydrogenation or other chemical or physical modification. It was found that the plants of the present invention can be formed through the combination (as described) of genetic determinants that were found to be present in the Pervenets sunflower and the H-55-9-2-1 or H-55-9-2-2 sunflower.
