Effects of phytoplasma infection and Fe starvation on Fe concentration in whole leaves, midribs and roots. Fe concentration in whole leaves, leaf midribs and roots of H/+Fe, I/+Fe, H/−Fe, and I/−Fe tomato plants. Fe concentration was determined by ICP-OES. Results are expressed as mean ± SD (n = 6). DW: dry weight. Different letters indicate statistically significant differences (P < 0.05) among conditions (one-way ANOVA followed by Holm-Sidak’s test)
