    in other cells outside the roots . . . . . .

    I think you are mistaken. I think the gene is expressed in all of the plant's cells, because we don't have that level of control yet over gene-switching. And may never.

    In medicine, we can place genes into particular cells and express them only in one specific area.  But we do that by actually placing the genes there AFTER the cells have differentiated.

    In GMOs, the genes are all in just one cell--the fertile seed. And every cell in the plant is a copy of that one seed cell.

    In the end, reality always wins.
