Dystroglycan and Mitochondrial Ribosomal Protein L34 Regulate Differentiation in the Drosophila Eye

An mRpL34 transgene rescues external eye defects associated with Df(2R)Dg248.
SEM of two day old female adult eyes (A–E) and the corresponding histology (A′–E′). A wild type eye shows the ordered array of ommatidia both on the surface (A) and within the retina (A′). On the surface, a Dg043 eye (B) has a small region (arrow) of mispatterning of ommatidia. Within the Dg043 retina (B′) the patterning of the retina is normal. The surface of a Dg086 eye (C) as well as the within the retina (C′) shows a normal pattern of ommatidia. The Dg086 eye shape is more spherical relative to wild type. A Df(2R)Dg248 mosaic eye has a grossly disrupted array of ommatidia on its surface (D) as well as within (D′). Expression of an mRpL34 transgene in a Df(2R)Dg248 mosaic eye significantly rescues the external and internal eye disruption (E and E′). The scale bars are 100 µm (A–E); 10 µm (A′–E′). Line marks the retinal equator in A′ and C′.
