  1. Silicon alleviates iron deficiency in cucumber by promoting mobilization of iron in the root apoplast Volume 198, Issue 4, 1096–1107, Article first published online: 18 March 2013

New Phytologist 198 (2013), 1096–1107.

Since its publication, the authors of Pavlovic et al. (2013) have brought to our attention an error in the units on the y-axis labels of Fig. 6 in their article. The units on the y-axis labels of panels (a) and (b) should read mM and not μM. The correct figure is printed below.

Figure 6.

Effect of duration of Fe deficiency and Si supply on the concentrations of citrate (a) and malate (b) in xylem sap of cucumber (Cucumis sativus). –Si (black bars); +Si (grey bars). Plants were precultured in complete nutrient solution (10 μM Fe) −Si or +Si (1.5 mM) for 7 d and then transferred to Fe–free nutrient solution –Si or +Si. Data are means ± SD (n = 4). Significant differences between treatments (P < 0.05) are indicated by different letters.

We apologize to our readers for this mistake.
