dEHBP1 controls the development of R8 photoreceptor cells. Loss of dEHBP1 within clones of cells negatively marked by nuclear GFP leads to the emergence of supernumerary Ato positive R8 phtotoreceptor cells (A–C) and of supernumerary Sens-positive R8 photoreceptor cells (D–F). The absence of neur within clones of cells negatively marked by nuclear GFP leads to the emergence of supernumerary Sens-positive cells (G–I). Note the greater severity of the Sens phenotype in neur clones (I) than in dEHBP1 clones (F). Scale bars: 10 nm.
