Figure 4. AMPylation of BiP is required for maintaining structural plasticity in the retina.

(A–C) Representative TEM images of retina thin sections from the indicated genotypes with either standard LD (A), the stress-inducing LL (B) or recovery treatment (C). Scale bars: 1 µM. Yellow boxes indicate rhabdomeres shown in high magnification images. High magnification scale bars: 0.5 µM. (D) Percentages of flies with intact deep pseudopupil following LD, LL and Rec. N = 3 independent biological replicas with approximately 50 flies scored per genotype per replica. Bar graphs show means ± SD.
