Fig. 3From: Comparative metabolomic analysis reveals the variations in taxoids and flavonoids among three Taxus speciesAnalysis of the relative amounts of taxoids in the Taxus metabolomes from the three different species. (a) Overview of the taxol biosynthesis pathway. (b) The relative accumulation of taxoids, intermediates and derivatives in the three different species. The heatmap scale ranges from -4 to +4 on a log2 scaleBack to article page
