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.

International Classification:

A01H005/00

US Classification:

800/278000, 800/320100

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.

US Classification:

4351723

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.
