WebFeb 7, 2024 · Flavones, one of the largest classes of flavonoids in plants, have a variety of bioactivities and participate in the resistance response of plants to biotic and abiotic stresses. However, flavone synthase (FNS), the key enzyme for flavone biosynthesis, has not yet been characterized in mulberry. In this study, we report that the leaves of certain … WebJan 1, 2013 · Two distinct flavone synthases (FNS), FNS I and FNS II, have been characterized that convert flavanones to flavones. In most plants, FNS is a P450 enzyme (FNS II), but species in the Apiaceae have been found to contain the 2-oxoglutarate-dependent dioxygenases (2OGD) FNS I. Flavonols are formed from DHFs by the FLS.
