Figure 6A.The double mutant strain, sfp1Δ, afo1Δ
was constructed as described in the Materials and Methods
section, tested for lifespan, and compared with both single
mutant strains and the wild type. The sfp1? strain grows very
slowly although it is respiratory-competent, is highly resistant
to t-BHP and is very short-lived. The short lifespan of sfp1Δ
is partially rescued by afo1Δ.
