Functional Characterization of a Flavone Synthase That Participates in a Kumquat Flavone Metabolon [PDF]
Frontiers in Plant Science, 2022 Flavones predominantly accumulate as O- and C-glycosides in kumquat plants. Two catalytic mechanisms of flavone synthase II (FNSII) support the biosynthesis of glycosyl flavones, one involving flavanone 2-hydroxylase (which generates 2-hydroxyflavanones ...

Characterization of flavone synthase I from rice
BMB Reports, 2008 Flavones are synthesized from flavanones through the action of flavone synthases (FNSs). There are two FNSs, FNS I and II. FNS I is a soluble dioxygenase present in members of the Apiaceae family and FNS II is a membrane bound cytochrome P450 enzyme that has been identified in numerous plant species.

Cloning and Characterization of Flavone synthase I from Populus deltoids [PDF]
Journal of Applied Biological Chemistry, 2009 Poplar contains various flavonoids including naringenin, kaempferol, myricetin, apigenin, luteolin, rhamnetin, and quercetin. These flavonoids are synthesized from naringenin with various enzymes. However, none of genes from poplar involved in flavonoid biosynthesis have been biochemically characterized.

Identification of flavone phytoalexins and a pathogen-inducible flavone synthase II gene (SbFNSII) in sorghum [PDF]
Journal of Experimental Botany, 2009 Following inoculation with the anthracnose pathogen Colletotrichum sublineolum, seedlings of the sorghum resistant cultivar SC748-5 showed more rapid and elevated accumulation of luteolin than the susceptible cultivar BTx623. On the other hand, apigenin was the major flavone detected in infected BTx623 seedlings.

Expression of Flavone Synthase II and Flavonoid 3′-Hydroxylase is Associated with Color Variation in Tan-colored Injured Leaves of Sorghum [PDF]
Frontiers in Plant Science, 2016 Sorghum (Sorghum bicolor L. Moench) exhibits various color changes in injured leaves in response to cutting stress. Here, we aimed to identify key genes for the light brown and dark brown color variations in tan-colored injured leaves of sorghum.

Bivalent RNA interference to increase isoflavone biosynthesis in soybean (Glycine max) [PDF]
Brazilian Archives of Biology and Technology, 2013 In this work, a bivalent RNA interference (RNAi) plant-transformation vector was constructed to silence both the flavanone 3-hydroxylase (F3H) gene and the flavone synthase II (GmFNSII) gene in soybean (Glycine max).
