The expression of anthocyanin biosynthesis genes during flower colour development in Anthurium andraeanum (anthurium) was studied. A cDNA library constructed from mRNA the anthurium spathe, and full‐length clones identified for flavonoid biosynthetic enzymes chalcone synthase (CHS), flavanone 3‐hydroxylase (F3H), dihydroflavonol 4‐reductase (DFR) anthocyanidin (ANS). These were used to measure transcript levels spathe development, cultivars with different colours, over diurnal cycle, spadix. CHS , F3H ANS expressed at all stages spadix development. However, DFR varied significantly between stages, may represent a key point regulation. rhythm abundance also observed, high dawn dusk low noon. Control differs that described flowers other species, regulatory complex mix developmental environmental control signals.
