PAL and 4CL activities in Arabidopsis stems over a day–night cycle. Activities of PAL and 4CL from the basal 0–2 cm (black bars) or 2–4 cm (white bars) of 4-week-old Arabidopsis stems. Shaded area means stems were sampled at night. Data represent mean ± SD (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. Bars with a shared letter have no statistical difference from each other
