Analysis of transcription factors associated with the anthocyanin biosynthesis pathway. (a) Families of related transcription factors. (b) Heat map of bHLH transcription factors. (c) Heat map of MYB and WD40-repeat transcription factors. Gene expression was scaled using Z-scores of fragments per kilobase of exon per million fragments mapped (FPKM) for mean values of three biological replicates in heatmaps. W, White light; B, Blue light; R, Red light. CK indicates normal photoperiod irradiation; T indicates continuous photoperiod irradiation. (d) Correlation network analysis of anthocyanin structural genes with anthocyanin components, MYB TFs. (e) Correlation network analysis of anthocyanin structural genes with anthocyanin components, bHLH TFs. Only Pearson correlation coefficients (PCC) ≥ 0.80 or ≤ -0.80 are shown. solid line, positive correlation between genes; dashed line, negative correlation between genes
