Fig. 5From: Comparative transcriptome analysis identified important genes and regulatory pathways for flower color variation in Paphiopedilum hirsutissimumOverview of anthocyanin biosynthesis pathway and involvement of differentially expressed genes (DEGs) in Paphiopedilum hirsutissimum flower. Heatmaps were generated using Log2FC based on FPKM values and the DEGs encoding specific enzymes are denoted in blue color. In scale bar, red color shows upregulation, white color shows downregulation, and orange color means no change. Phenylalanine ammonia lyase (PAL), 4-coumarateCoA ligase (4CL), chalcone synthase (CHS), chalcone isomerase (CHI), flavone 3-hydroxylase (F3H), flavonol synthase (FLS), dihydroflavonol reductase (DFR), and UDP-flavonoid glucosyl transferase (UFGT), and leucoanthocyanidin dioxygenase (LDOX). NL, normal labellum; NP, normal petal; AL, albino labellum; AP, albino petalBack to article page
