Figure 4

Genes of the anthocynain biosynthesis pathway are differentially affected by exogenous sucrose and endogenous sugars (AtPAP2 OE lines). Genes that were significantly altered (P < 0.05) are shown (arrows). Solid arrows indicate gene expression in OE lines while empty arrows showed the sucrose-modulated genes in dark grown WT seedlings (Dark (S)). Abbreviations are as follows: AGI, Arabidopsis Genome Initiative; C4H, cinnamate-4-hydroxylase; 4CL, 4-coumaroyl-CoA synthase; CHI, chalcone isomerase; DFR, dihydroflavonol 4-reductase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3′-hydroxylase; F3′5′H, flavonoid 3′5′-hydroxylase; FLS, flavonol synthase; 3GT, 3-glucosyl transferase; 5GT, 5-glucosyl transferase; OMT, O-methyl transferase; PAL, phenylalanine ammonia-lyase; RT, rhamnosyl transferase; TT4, Transparent testa 4; TT5, Transparent testa 5; TT7, Transparent testa 7; UF3GT, UDP-Glc: flavonoid 3-O-glucosyltransferase.
