Figure 3.

GFP-Spo14 staining in living ARF1 arf2 and arf1-myc arf2 cells. The panel on the left shows GFP-Spo14 staining in ARF1 arf2 cells at 20 h after transfer to sporulation medium. The cells have completed sporulation, as evidenced by the uniform circles of GFP-Spo14 staining (arrow). The panel on the left shows GFP-Spo14 staining in arf1-myc arf2 cells 20 h after transfer to sporulation medium. The arrows indicate the small circles of GFP-Spo14 staining; these never progress past this size.
