Changes in gene expression in flavonoid biosynthesis of the glu1-2 mutant. Simplified schematic representation of the flavonoid biosynthetic pathway and the genes showing different expression levels in glu1-2 leaves and root. Gene IDs indicated in blue are upregulated whereas those indicated in red are downregulated. Enzymes: (1) phenylalanineammonia lyase (PAL), (2) cinnamate 4-hydroxylase, (3) 4-coumarate-CoA ligase, (4) chalcone synthase, (5) chalcone isomerase, (6) flavanone 3-hydroxylase, (7) flavonoid 3'-hydroxylase, (8) flavonol synthase, (9) flavonol glycosyltransferase. The figure is based on . The detailed data of the genes depicted in this figure are presented in Additional file 8.
