(L-O) Grh1 and Gvp36 involvement in AmphoB-induced autophagy-like proteolysis. (L, M) Representative electron microscopy images of grh1Δatg5Δpep4Δ (L) and gvp36Δatg5Δpep4Δ cells (M) treated with AmphoB (2.5 µg/ml, 24 hr). AP-like and AB-like structures were absent. (L) A unilamellar Golgi cisterna was observed in the cytoplasm (dotted square). Scale bar = 1 µm. (M) Formation of a Golgi stack, but not Golgi curvature, was observed (dotted square). Bar = 0.5 µm.
