[Study of degradation of flavonols in the mutants of poppy (Papaver somniferum L.)].

Abstract excerpt

We studied flavonol-degrading activity of cell-free extracts from petals of the flower color and structure mutants. The relationship between degradation of flavonols (kaempferol, quercetin, and myricetin) and biosynthesis of anthocyanins has been revealed. The highest flavonol-degrading activity has been revealed in white flower mutants towards all substrates, particularly, quercetin. The mutations inhibiting...
