Labeling percentage of measured soluble phenylpropanoids from the base of Arabidopsis stems supplied with 1 mM [¹³C₆]-Phe over the feeding time course. The plot of each metabolite was placed above its name on the pathway. Dashed lines mean multiple steps. Data represent mean ± SD (n = 3). Black squares indicate these metabolites were in the first group of the hierarchical clustering in Figure S4, and grey squares indicate these metabolites were in the second group
