  • Patent number: 7705215
    Abstract: This invention relates to a reproducible system for the production of stable, genetically transformed maize cells, and to methods of selecting cells that have been transformed. One method of selection disclosed employs the Streptomyces bar gene introduced by microprojectile bombardment into embryogenic maize cells which were grown in suspension cultures, followed by exposure to the herbicide bialaphos. The methods of achieving stable transformation disclosed herein include tissue culture methods and media, methods for the bombardment of recipient cells with the desired transforming DNA, and methods of growing fertile plants from the transformed cells. This invention also relates to the transformed cells and seeds and to the fertile plants grown from the transformed cells and to their pollen.

  • Publication number: 20030126634
    Abstract: The present invention provides methods for increasing yield in plants by introducing a gene encoding phosphinothricin acetyltransferase. The invention further involves a method of transferring said increased yield phenotype to other lines of plants by crossing. A maize transformant is identified in which the phosphinothricin acetyltransferase gene integration event is correlated with increased yield.

  • Patent number: 5969213
    Abstract: This invention relates to stable and genetically transformed cereal plants, other than maize or rice, that comprise an exogenous DNA expressing phosphinothricin acetyl transferase to impart resistance to phosphinothricin in said cereal plants. Cereal plants within the scope of the invention include, but are not limited to, wheat, barley and oats. The invention also pertains to transgenic cereal plants which further comprise screenable markers and transgenic seed obtained from said plants.

  • Patent number: 5919675
    Abstract: This invention relates to a method for the production of stable, genetically transformed, Zea mays plants that comprise an exogenous DNA expressing phosphinothricin acetyl transferase to impart resistance to phosphinothricin in said plants. The method further comprises transforming said Zea mays plants with a second gene and further still wherein said second gene imparts insect resistance, such as the expression of a Bacillus thuringiensis toxin gene. The method for achieving stable transformation includes tissue culture methods and media, methods for the bombardment of recipient cells with said DNA's, and methods of regenerating fertile plants from transformed cells. The invention also pertains to a method of breeding said transgenic Zea mays plants with a either a non-transgenic plant or a transgenic plant, and the obtention of fertile transgenic plants and seed therefrom.

  • Patent number: 4943978
    Abstract: An interface apparatus and method is disclosed which allows communication of digital data messages between a first type of data terminals (10 and 65) employing a message protocol (FIG. 1a) with a "free text-type" message, and other user devices employing other digital message protocols. The invention is adapted to exploit the free text message capability of the first protocol. In accordance with the invention, the incoming user data messages are packed into one or more free text messages of the first message protocol, and conversely "unpack" free text messages from the data terminal employing the first protocol are unpacked and formatted into the message protocol format employed by the user device 65. The invention eliminates the necessity for expensive translation devices which translate the data, and allows a plurality of user data terminals to communicate via a link comprising the data terminals employing the first message protocol.
