Transcript profiling of genes in the flavonoid and anthocyanin biosynthetic pathways in Shanghua15 and Zhonghua12 at R7 stages. Heat map represents changes in transcripts in flavonoid and anthocyanin biosynthetic. Dots marked with red background represent increased abundances of metabolites. PAL: phenylalanine ammonia-lyase; C4H: cinnamic acid 4-hydroxylase; 4CL: 4-coumarate CoA ligase; CHS: chalcone synthase; CHI: chalcone isomerase; F3H: flavanoid 3-hydroxylase; DFR: dihydroflavonol 4-reductase; ANS: anthocyanidin synthase; FLS: flavonol synthesis; FNS: flavone synthase; LAR: leucocyanidin reductase; ANR: anthocyanin reductase; UFGT: UDP glucose-flavonoid 3-O-glcosyl-transferase; MT: methyltransferase.
