Labeling incorporation into lignin in stems fed with [13C6]-Phe. Labeling percentage of lignin monomers in stems fed with 0.3 mM [13C6]-Phe for 48 h were analyzed by DFRC/GC/MS. Data represent mean ± standard deviation (n = 3). The means were compared by one-way ANOVA and statistical difference by Tukey HSD test (p < 0.01) was indicated by letters
