FIG. 3.

Sod2 is required for growth at 30 and 37°C. Strains sod2Δ, sod2Δ SOD2, and wild-type (WT) H99 were serially diluted on YPD agar plates and incubated at 25, 30, and 37°C for up to 3 days. The sod2Δ mutant strain exhibited a progressively severe ts phenotype at 30 and 37°C. The phenotype of the sod2Δ SOD2 reconstituted strain was similar to that of wild-type strain H99.
