Anthocyanin biosynthetic pathway and expression of related genes during bract development in poinsettia varieties. (left) Differentially expressed genes (FDR ≤ 0.05) in the three stages of bract development are depicted by S1, S2 and S3 (Stages 1, 2 and 3, respectively) symbols next to the genes. Stages colored in red indicate a higher expression of the respective gene in the red poinsettia variety. Stages colored in blue indicate a higher expression of the respective gene in the white poinsettia variety. (right) Heatmap of the genes involved in each process of the pathway. Gene expression is represented by Log10(FPKM+ 1). FPKM = Fragments per kilobase per million. For gene abbreviations refer to Table 2
