cdf-1(lf) and sur-7(lf) mutants display heightened toxicity toward increasing concentrations of Zn2+. Animals grown on metal supplemented media were scored for percentage reaching egg-laying maturity after 4 days (Materials and methods). Each bar represents the mean of three independent experiments and shows the calculated standard deviation. sur-7(ku119) and cdf-1(n2527) responses were found to be significantly different from wild type (but not one another) at and above 1.0 mM Zn2+ (Tukey–Kramer: α 0.05).
