Fig. 3From: Comparative metabolomics reveals the metabolic variations between two endangered Taxus species (T. fuana and T. yunnanensis) in the HimalayasVariations in the abundances of the precursors, intermediates, competitors of taxol between T. fuana and T. yunnanensis. a An overview of the taxol biosynthesis pathway. b A heatmap of the relative amounts of the precursors, intermediates, competitors of taxol in the two Taxus species. The precursors from MEP pathway were included in a red box, the intermediates and derivatives were included in a purple box, and the competitors of taxol were included in a green box. The heatmap scale ranges from − 3 to + 3 on a log2 scaleBack to article page
