(I-K) Quantification of autophagy changes due to GlyS gene knockdown in Dmef2-Gal4, UAS-GFP-Atg8 larvae starved on low-nutrient food +2.5 mg/ml CQ for 6 h. SEM is indicated, with n = 5 (I) or n = 10 (J-K) ventral longitudinal muscles from individual animals (*p<.05, **p<.01). (I) Each of the four UAS-GlyS RNAi transgenes tested caused a significant decrease in the total area of GFP-Atg8vesicles in the muscle compared to the UAS-whitei control. (J) Vesicle number was unchanged by GlyS knockdown. (K) UAS-GlyS RNAi caused a highly significant decrease in the mean vesicle size (area) compared to the control.
