Figure 7

Effects of rhizotoxic ion challenge on transgenic Arabidopsis lines expressing the yeast Tpo1p transporter. (a) Representative images of 7-d old seedlings of the wild type (Col-0) and TPO1 (TPO1L1, L2, L4) transgenic lines grown on media containing Co2+, Cu2+, Ni2+, Al3+ or Cd2+. Plant growth under control conditions is shown in Fig. 1 and Table 1. (b) Effect of Co2+, Cu2+, Ni2+, Al3+ or Cd2+ toxicity on PR elongation (upper panel) and shoot biomass (lower panel) of seedlings of the wild type (Col-0) and TPO1 (TPO1L1, L2, L4) transgenic lines. Values represent means ± SD (n = 8), with similar results being obtained in three independent experiments performed with different seed batches. Asterisks denote statistically significant differences between ScTPO1-expressing lines and the wild type (*P < 0.05, **P < 0.01, ***P < 0.001; Student’s t-test).
