Figure 6. Arf1 is involved in mitophagy and autophagy.
- arf1 mutants are defective in mitophagy. Strains expressing mt-Rosella were grown at permissive temperature overnight, diluted, grown to logarithmic phase at the indicated temperatures, then shifted to starvation in SD-N for 14 h at indicated temperatures and imaged thereafter. Scale bar, 5 μm. Half of the culture was shifted to restrictive temperature for 1 h and imaged thereafter.
- Quantification of data in (A) from three independent experiments in which at least 100 cells were scored. Standard deviation is given.
- arf1 mutants are defective in autophagy. Strains expressing GFP-Atg8 from its endogenous promoter were cultured as in (A) and starved in SD-N for 5 h. The arrival of GFP-Atg8 in the vacuole as a readout for autophagy was scored in arf1 mutant cells. Data from three independent experiments in which at least 100 cells were scored are shown. Standard deviation is given.
