Pigment production in inflorescences of arabidopsis plants stably transformed with 35S: AmDOD. Inflorescences from 35S: AmDOD arabidopsis line 6 were infiltrated with either water or 10 mM L-DOPA for 24 h and examined under white light (upper panel) or blue light (lower panel). Those fed L-DOPA accumulated yellow to orange pigments and under blue light showed the autofluorescence typical of betaxanthins. The inflorescences not fed L-DOPA did not produce visible coloured pigments and did not show autofluorescence.
