Crb and Ex function in a common pathway to regulate interommatidial cell number. (A–A″) A pupal eye containing crb82-04 clones (GFP-negative) (A), and stained for Dlg (A’). Superimposed image is shown in A″. (B–G) Pupal eyes of the indicated genotype and stained for Dlg. The genotypes are: (B) y w ey-flp Ubi-GFP FRT19A /mer4 FRT19A, (C) y w ey-flp; FRT 82B kibradel /FRT 82B Ubi-GFP, (D) y w ey-flp; FRT40A exe1/FRT40A Ubi-GFP, (E) y w ey-flp Ubi-GFP FRT19A /mer4 FRT19A; FRT 82B crb82-04 /FRT 82B Ubi-GFP, (F) y w hsp-flp; FRT 82B kibradel crb82-04 /FRT 82B Ubi-GFP, (G) y w ey-flp; FRT40A exe1/FRT40A Ubi-GFP; FRT 82B crb82-04 /FRT 82B Ubi-GFP. Twenty ommatidial clusters of each genotype were used for counting interommatidial cells.
