This was a great success since roses have no natural gene for producing blue pigments; further, roses do have a gene that controls the destruction of blue pigment molecules. To obtain the blue color, researchers had to inject genes from pansies and other flowers to counteract the natural chemistry of the plant.Because the rose is a plant, the likely cloning vector used to introduce necessary genes was a
