Fig. 1From: Comparative metabolomics reveals the metabolic variations between two endangered Taxus species (T. fuana and T. yunnanensis) in the HimalayasUntargeted metabolite profiling reveals the variations in the abundance of metabolites between T. yunnanensis and T. fuana. a A picture of the twigs of T. fuana. b The collection sites of T. fuana (Jilong) and T. yunnanensis (Motuo) were indicated by green and red small dots, respectively. c A picture of the twigs of T. yunnanensis. d A heatmap of the metabolites identified in the metabolomes of the two Taxus species (n = 15). The heatmap scale ranges from − 4 to + 4 on a log2 scaleBack to article page
