(A) Drosophila S2 cells stably expressing GFP-RFP-Atg8a showed an increase in the percentage of cells containing two or more autolysosomes after starvation, which was blocked after Bafilomycin A1 (BafA1) treatment. At least 50 cells were manually quantitated in three independent experiments (n = 3). Statistical significance was determined using one-way ANOVA with a Dunnett post test (**, P < 0.01). (B) Representative images of S2-GFP-RFP-Atg8a cells after the indicated treatments.
