Figure 4. Ato^Bm can rescue the loss of eye of the ato¹ mutant.

A) Adult compound eyes of wt, Ato^Dm-rescued, Ato^Bm-rescued and ato¹-mutant flies (left to right). Inset shows dorsal views of corresponding fly genotypes. Quantitative data are shown in Fig. 5C. Control ‘wt’ genotype is ato^5′EYE3′-Gal4 ato¹/+; rescued flies genotypes are UAS-ato^X/+ ; ato^5′EYE3′-Gal4 ato¹/Df(3R)p¹³; ato mutant genotype is ato^5′EYE3′-Gal4 ato¹/Df(3R)p¹³. B) L3 eye discs of wt, Ato^Dm-rescued, Ato^Bm-rescued and ato¹-mutant flies (left to right). Discs are stained for Sens to mark R8 neurons, the pan-neural marker Elav to highlight all photoreceptors and the retina-identity determinant Eya to mark the developing eye disc. Single channels for Sens and Elav are shown below.
