1.14.19.76 | metabolism |
expression of FNSII is related to the synthesis of flavones (apigenin and luteolin). The enzyme is associated with colors in tan-colored injured leaves in sorghum |

1.14.19.76 | evolution |
phylogenetic analyses of the subfamily of plant CYP93B enzymes indicate the evolution of a gene encoding a flavone synthase which originally catalyzes the direct conversion of flavanones into flavones, via early gene duplication into a less efficient enzyme with an altered catalytic mechanism. Ultimately, this allows the evolution of the legume-specific isoflavonoid synthase activity |

1.14.19.76 | metabolism |
the dark or light brown color variation in injured leaves of sorghums is associated with the gene expression of flavone synthase II and flavonoid 3'-hydroxylase. Flavone synthase II pathway is activated to synthesize flavones (apigenin and luteolin) and the expression level of flavonoid 3'-hydroxylase changes the balance of apigenin and luteolin. Expression of flavone synthase II is related to the synthesis of flavones (apigenin and luteolin) and the expression level of flavonoid 3'-hydroxylase is related to the balance of apigenin and luteolin. Expression of flavone synthase II and flavonoid 3'-hydroxylase is thus associated with dark or light brown coloration in tan-colored injured leaves of sorghum. Expression of both flavone synthase II and flavonoid 3'-hydroxylase leads to the synthesis of apigenin and luteolin in Sorghum bicolor #7 |

1.14.19.76 | malfunction |
the lignin of the fnsII mutant is completely devoid of tricin, indicating that FNSII activity is essential for the deposition of tricin-bound lignin in rice cell walls. The mutant also shows substantially reduced lignin content with decreased syringyl/guaiacyl lignin unit composition. The loss of tricin in the mutant lignin appears to be partially compensated by incorporating naringenin, which is a preferred substrate of OsFNSII. The fnsII mutant is further revealed to have enhanced enzymatic saccharification efficiency, suggesting that the cell wall recalcitrance of grass biomass may be reduced through the manipulation of the flavonoid monomer supply for lignification |
