Metabolic profiles of soluble phenylpropanoids from the base of Arabidopsis stems supplied with 1 mM [13C6]-Phe over the feeding time course. Endogenous (grey) and 13C6 labeled (black) compounds were quantified with LC/MS–MS and normalized to fresh weight of stem tissue. The sum of endogenous and labeled concentrations of each metabolite can be found in Figure S6. The plot of each metabolite measured was placed above its name on the pathway. Dashed lines mean multiple steps. Data represent mean ± SD (n = 3)
