(I) AB-like structures accumulated in the vacuole. Scale bar = 0.5 µm. (J) AB-like structures containing lipid particles and mitochondria accumulated in the cross-section of the vacuole. An autophagosome (AP)-like double-membrane compartment containing a ribosome and Golgigranule is present in the cytosol. Scale bar = 0.5 µm. A magnified photo is available in Appendix Fig. S4B. (K) The cells containing AB-like structures were counted under electron microscopy [no treatment (NT): n = 20, AmphoB: n = 192]. * p < 0.01 vs the value of NT.
