  • Transformation of cotton plants
    Patent number: 6624344
    Abstract: A method for producing transformed cotton plants. The method comprising providing cotton explants, incubating the cotton explant in the presence of a vector comprising a selectable marker to produce treated explants, growing the treated explants to produce callus and selecting transformed callus.
