FIGURE 5.

Gene expression profiles of identified transcription factor and protein-protein interaction network of key structural enzymes and TFs involved in anthocyanin biosynthesis in L. radiata flowers. (A) K-means clusters of DEGs based on standardized (log₂ transformed) FPKM of L. radiata petals at flower development stage (FB, FL1, FL2, and R). Number of genes that were clustered in every subclass are shown above each Figure. (B) Protein–protein interaction network constituted by protein sequences of differentially expressed transcription factors and structural genes involved in anthocyanin synthesis of L. radiata petals. Genes that have the higher weight are depicted in ‘yellow and orange,’ the ‘blue edges’ correspond to co-expressed strong links and the ‘yellow edges’ correspond to co-expressed weak links.
