<p>A plant tranformation expression cassette for transforming host plant cells with a selectable marker gene is disclosed. The cassette includes, operatively linked in sequence in a 5' to 3' direction, (i) a DNA promoter sequence from the rice beta-glucanase 9 (gns9) gene; (ii) a selectable marker gene, and (iii) a 3' untranslated terminator region. Also disclosed are an expression cassette pair containing the transformation vector, a method of obtaining transformed monocots whose seeds produce a selected heterologous protein during seed germination, and a plant whose cells are tranformed with the chimeric selectable marker gene.</p> |
