摘要:
The present invention provides compositions and methods for regulating expression of nucleotide sequences in fungi. Compositions are novel nucleotide sequences for a tissue preferred promoter isolated from the Agaricus bisporus lectin gene. The sequences drive expression preferentially to fruit body tissue. A method for expressing a nucleotide sequence in fungi using the regulatory sequences disclosed herein is provided. The method comprises transforming a fungal cell to comprise a nucleotide sequence operably linked to one or more of the regulatory sequences of the present invention and regenerating a stably transformed fungus from the transformed cell.

摘要:
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.
