<p>A rose is produced in which an introduced gene is only present in a part of the cells thereof, such as cells of the L1 layer of flower petals, but is not present in germ cells such as pollen cells or ovule cells. Since the introduced gene is not propagated to other roses even when this rose is crossed with other roses, the possibility of dispersal of the introduced gene can be completely negated.</p> |
