Abstract
This invention relates to the discovery that the prokaryotic enzyme, aminoglycoside 3"-adenyltransferase (AGAT), in particular as encoded by a bacterial aadA gene, is useful as a selectable marker for transformed plants. The enzyme conveys resistance to spectinomycin and streptomycin. Such markers are particularly advantageous because they are non-lethal, provide rapid visual identification of transformed cells and permit selection in media containing either spectinomycin or streptomycin. In addition, AGAT may be used as a selectable marker which differentiates by enabling survival on selective media.
