  • a Superoxide resistant: SOD1ox SOD2ox, SOD1ox CTT1ox, SOD1ox, SOD2ox, Bcl-2ox, ras2Δ, and sch9Δ.

  • b Superoxide sensitive: sod1Δ and sod1Δ ctt1Δ.

  • c Significantly different versus wild type (WT). When four or less samples were available, the corresponding strains were excluded from statistical analysis. Chi square test (χ2 = 64, df = 10, P < 0.05) followed by Scheffé's post-test for multiple comparisons (P < 0.05).
