The effect of exogenous melatonin on Fe content in root cell wall components in the WT, nia1nia2noa1 and c-PTIO-treated Arabidopsis plants. Seven-day-old seedlings were grown in −Fe (0 μM Fe) or +Fe (50 μM Fe) medium without or with the presence of 5 μM melatonin (+MT) for 8 days. Then, these plants were taken to measure the Fe content in the root total cell wall (A), pectin (B), HC1 (C), and HC2 (D) fractions. Each bar is the mean ± SE of at least three replicates, and different lowercase letters above the bars indicate significant difference using Tukey’s test at p < 0.05.
