Betaxanthin production in arabidopsis seedlings stably transformed with 35S: AmDOD. 35S: AmDOD seedlings were grown on moistened filter disks either with (A to E) or without (F and G) 10 mM L-DOPA. Those fed L-DOPA accumulated yellow to orange/red pigments (A to C) and under blue light showed the autofluorescence typical of betaxanthins, as illustrated for the cotyledon (D) and hypocotyl (E). The seedlings not fed L-DOPA did not produce coloured pigments in either their cotyledons (F) or hypocotyls (G).
