Table 3. Percentage of metal accumulation in rosettes and roots of Arabidopsis thaliana 21 days after sowing, inoculated or not with Cupriavidus metallidurans CH34, in the presence or absence of copper.
| Rosettes (CH34/control) | Roots (CH34/control) | Rosettes (Cu/control) | Roots (Cu/control) | |||
|---|---|---|---|---|---|---|
| Element | MS1/2 | MS1/2 + 50 µM Cu2+ | MS1/2 | MS1/2 + 50 µM Cu2+ | ||
| B | +29%** | +30% | +32% | – | +109% | +380% |
| Co | +68% | +40% | +67% | +73% | +50% | +20% |
| Cu | +11% | +55% | +18% | +38% | +315 | +493% |
| Fe | +42% | +9% | +91% | −31% | +277% | +315% |
| Mn | +11% | +33% | +46% | +10% | +33% | +59% |
| Mo | – | +60% | −61% | +64% | −27% | −69% |
| Zn | − | +21% | +38% | +71% | +54% | +30% |
Notes.
All values were calculated as percentages of the metal level (μg of metal g−1 of dry weight) in inoculated versus non-inoculated plants (CH34/control), and plants in the presence or absence of copper (Cu/control).
Not significant changes.
