Boron and calcium concentrations of wild type and NtXIP1;1‐silenced N. tabacum leaf samples grown under toxic or deficient soil boron concentrations. (a) Boron (upper panel) and calcium (lower panel) concentrations of abaxial epidermal peels, young (6th leaf) and old (3rd leaf) leaf samples of wild type (WT) and NtXIP1;1‐silenced plants II‐1.2 and II‐2.2 grown in B‐sufficient (2.4 mg B/kg soil) or B‐deficient (<0.1 mg B/kg soil) soil substrate. Values represent means ± SE (n = 6). Asterisks indicate significant different nutrient concentrations between the WT and the NtXIP1;1‐silenced plants (*p < 0.05; Student's t test). (b) Boron (upper panel) and calcium (lower panel) concentrations of young (6th leaf) and old (3rd leaf) non‐necrotic leaf samples of WT and NtXIP1;1‐silenced plants grown on B‐sufficient (2.4 mg B/kg soil) or toxic B (100 or 130 mg B/kg soil) soil substrate concentrations. Values represent means ± SE (n = 3)
