Fig. 5From: Transcriptome analysis of Clinopodium gracile (Benth.) Matsum and identification of genes related to Triterpenoid Saponin biosynthesisProposed pathways for triterpenoid saponin biosynthesis in C. gracile. Expression levels of unigenes encoding enzymes that catalyze each step of the triterpenoid saponin biosynthesis pathway are shown. “CL” and “Un” indicates a cluster of transcripts and unigenes, respectively. F, flowers; L, leaves; S, stems; R, roots. The higher and lower expression level of unigenes are indicated in red and green, respectivelyBack to article page
