  • Selection marker
    Patent number: 6660910
    Abstract: This invention is concerned with the use of cyanamide hydratase as a selection marker in plant transformation. Cyanamide acts as a herbicide and plants transformed with the gene coding for cyanamide hydratase are able to convert the cyanamide into urea which enables the selection of transformed plants by survival under cyanamide pressure.
