We have detected a flavonoid 3’,5‘-hydroxylase (F3’,5’H) in the microsomal fraction of Petunia hybrida flowers. Activity varied with the development of flowers, peaking immediately prior to and during anthesis, but was absent in mature flowers. F3’,5’H activity in flower extracts from genetically defined floral color mutants correlated strictly with the genotypes H f l and H f 2 . No activity was detected in flowers from mutants homozygous recessive for both alleles. F3’,5’H activity was… CONTINUE READING
