Fig. 5. mib1 enhances the lateral inhibition phenotype of neur. (A-C) Nota stained for Sens (red, A'-C') to reveal SOPs. (A,B) Mutant clones marked by GFP expression; (C) mutant clones marked by GFP absence. Arrows indicate mutant areas. (A) mib1^EY9780 clones do not produce supernumerary SOPs. (B) neur¹ mutant clones show mild defects. (C) neur¹ mutant clones in a mib1^EY9780 background show severe hyperplasia of SOPs. Scale bar: 40 µm.
