A-D Appearance of autophagic structures (marked with GFP-Atg8a) during wound closure in the epidermis of control third instar larvae and after epidermal knockdown of the autophagy pathway components Atg1, Atg5, Atg6, Atg7 or Atg12. All constructs are expressed in the epidermis under the control of the A58-Gal4 driver. (A) Time points from movies of wounded epidermis. The wounds have closed by 2 h in all cases. (B) Higher magnification of the areas marked by magenta boxes at t=120 min. (C) Quantification of the appearance of GFP-Atg8a puncta in the imaged area (10000 µm2) 3 control larvae, shown for each individual larva. (D) Quantification of number of GFP-Atg8a puncta in different genetic conditions measured in an area of 10000 µm2 at the time of wound closure; n=4-10 larvae each genotype, for the detail see Data analysis.
