Shoot lipid peroxidation measured as TBARS in the hyperaccumulator T. goesingense (black) and the non accumulator A. thaliana (white) formed in response to each of the 4 different metal treatments after growth in normal media followed by transfer and growth on plates containing 1/2 strength MS medium with 125 μM Ni (NO3)2, 125 μM Co (NO3)2, 125 μM Zn (NO3)2, or 75 μM Cd (NO3)2 for a period of 8 days. Values represent difference in TBARS compared to growth on control media without added metals. Data represents averages (n = 4) ± SD. (*p < 0.05; ** p < 0.01, t-test)
