Figure 5. Differentially expressed genes involved in flavonoid and phenylpropanoid synthesis.

The green circle represents SW, and the yellow circle indicates seed. Arrows pointing up show increased expression; arrows pointing down show decreased expressions. Abbreviations: PAL, phenylalanine ammonia lyase; C4H, cinnamate 4-hydroxylase; 4CL, 4-coumarate-CoA ligase; CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; F′3H, flavonoid 3′-hydroxylase; FLS, flavonol synthase; FGT, flavonol glycosyltransferase; DFR, dihydroflavonol 4-reductase; ANS, anthocyanidin synthase; AGT, anthocyani(di)n glycosyltransferase; AAT, anthocyanin acyltransferase; GST, glutathione S-transferase; ANR, anthocyanidin reductase. This scheme was based on the analysis by Lillo et al. (2008) [98].
