Schematic representation of phenylpropanoid/flavonoid pathway as affected by the chlorosis mutation. Red and green font indicate up- and down-regulated genes, respectively, in the chlorotic leaves compared to shaded plants. Significantly changed metabolites are shown with a barplot (E and G indicate chlorotic and green leaves, respectively) while compounds that were not identified in this study are shown in gray font. PAL, phenylalanine ammonia-lyase; C4H, cinnamate 4-hydroxylase; 4Cl, 4-coumarate--CoA ligase; CHI, chalcone isomerase; CHS, chalcone synthase; F3′5′H, flavonoid 3′, 5′-hydroxylase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3′-monooxygenase; FLS, flavonol synthase; DFR, dihydroflavonol-4-reductase; ANR, anthocyanidin reductase; ANS, anthocyanidin synthase; LAR, leucoanthocyanidin reductase
