Growth response to excess Zn, Cu and Cd stress in wild-type (WT), oszip1 mutant, RNAi and OX lines. Two weeks-old young rice plants were grown in the nutrient solution supplemented with 0.4 (normal) and 1000 (high) μM Zn or 0.2 (normal) and 20 (high) μM Cu for 10 days or with 0 and 80 μM Cd for 4 d or 1 μM Cd for 30 d. a-c Dry weight of WT, oszip1, RNAi and OX plants exposed to Zn excess. d-f Dry weight of WT, oszip1, RNAi and OX plants exposed to Cu excess. g-k Dry weight of WT, oszip1, RNAi and OX plants exposed to Cd. Vertical bars represent standard deviation. Asterisks indicate that the mean values are significantly different between the transgenic plants/mutants and wild-type (p < 0.05)
