Pigment production in antirrhinum petals transiently transformed with 35S: AmDOD. A plasmid construct containing 35S: AmDOD was introduced into the adaxial epidermis of antirrhinum petals using particle bombardment. At 24 h after bombardment the bombarded petals were infiltrated with 10 mM L-DOPA and incubated for a further 24 h before observation. A representative petal is shown as viewed under white light (left) or blue light (right).
