Expression pattern of anthocyanin biosynthetic genes. Expression pattern for genes annotated to enzymatic reactions in anthocyanin-related pathways in PlantCyc are shown. (A) Genes encoding leucoanthocyanidin dioxygenase, catalyzing EC 22.214.171.124, dihydroquercetin synthesis from leucoanthocyanidin or cyaniding synthesis from leucoanthocyanidin. (B) Genes for enzymes catalyzing 3-O-glucosylation of delphinidin (EC 126.96.36.199). Both are annotated to PlantCyc pathway anthocyaninin biosynthesis (delphinidin 3-O-glucoside).
