In many of the egg chambers containing ATG1 mutant FC clones, we observed more than the 16 cell cysts normally present in WT egg chambers (31.3 +/-6.0% in ATG1 mutant versus 3.4 +/-2.9% in WT eggs, total number of ovaries counted were 67 and 55, respectively, Figure 1A, A’), whereas an unusual reduction in cyst number was detected less frequently (Figure 1B, B’). Here, ULK1 is linked to cyst.
