Phenylpropanoid metabolism along wild-type Arabidopsis stems. a Content of endogenous (white bars) and labeled (black bars) Phe and p-coumarate along the stems of 4-week-old wild-type Arabidopsis fed with 0.3 mM [13C6]-Phe for 6 h. Data represent mean ± standard deviation (n = 3). One-way ANOVA was used for unlabeled or labeled metabolites and statistical difference by Tukey HSD test (p < 0.01) was indicated by letters. b Activities of PAL and 4CL from base to top along the stems of 4-week-old Arabidopsis without feeding. Data represent mean ± standard deviation (n = 3). One-way ANOVA was tested for PAL and 4CL assays respectively and statistical difference by Tukey HSD test (p < 0.01) was indicated by different letters
