Transcript profiling FPKM and phylogenetic tree of structural genes and transcription factors in the flavonoid biosynthesis pathway in cv. ‘Zibao’ (CK) and the after bagging female flower tissues (BF). (A) Reconstruction of the phenylpropanoid-flavonoid biosynthetic pathway with the significantly differentially expressed structural genes (yellow). Enzyme names, log2 (expression ratio) and expression patterns are indicated at the side of each step. The expression pattern for each uni-transcript is shown on two grids, with the left one representing the FPKM value of ‘CK’, and the right one of ‘BF’. Grids with 8 different gray-scale levels show the FPKM value, with the RPKM values 0–10, 10–20, 20–40, 40–80, 80–160, 160–320, 320–640 and 640–1280 represented by gray-scale levels 1–8, respectively. (B) The expression patterns of the candidate MYB transcription factor involved in the regulation of flavonoid compounds in CK vs. BF and phylogenetic clustering of the recruited R2R3-MYBs with anthocyanin biosynthesis-related MYBs from other plants. (C) The expression patterns of the candidate bHLH transcription factor involved in the regulation of flavonoid compounds in CK vs. BF and Phylogenetic clustering of the recruited bHLHs with anthocyanin biosynthesis-related bHLHs from other plants. *P < 0.05
