Metal concentrations of wild-type and ysl1ysl3 plants. A and B, Metal concentrations of plants grown on MS agar for 18 d. Results are given as percentage change in mutant (n ≥ 9) compared to wild type (n ≥ 9). *, Significance at P ≤ 0.05; **, significance at P ≤ 0.01. A, Metal concentrations of shoots. Ranges of concentrations (in ppm) were Mn, 259 to 273; Fe, 54 to 70; Co, 0.65 to 0.70; Cu, 3.9 to 4.8; Zn, 151 to 168; and Mo, 3.6 to 5.3. B, Metal concentrations of roots. Ranges of concentrations (in ppm) were Mn, 112 to 126; Fe, 713 to 1,234; Co, 1.6 to 1.9; Cu, 4.6 to 5.4; Zn, 1,104 to 1,289; and Mo, 3.1 to 4.4. C, Metal concentrations of leaves of plants grown for 20 d on commercial potting mix. Results are given as ppm (n ≥ 9).
