Increased sensitivity of the <i>sod2434</i> mutants to H₂O₂ and paraquat exposure.

Average dimension of inhibition zone determined as the distance between paper disc and the front line of growth [mm], determined from three independent experiments. 5 µl of 10% H2O2 and 5 µl of 5 mg/ml paraquat, respectively, was deposited on a paper disc with a diameter of 5 mm; values given in bold indicate a significant difference between a given mutant and its corresponding parental strain (p<0.005; Student's t-test, two-tailed, unpaired; * indicates p<0.0005; ** indicates p<0.00001).
