Cbt causes an ectopic cell cycle in pupal wings. (A and B) Thirty hours APF, wings with GFP+-marked clones (green) expressing cbt by hs-flp; tub > CD2 > Gal4;tub-Gal80ts. Cbt induced ectopic DNA replication by EdU incorporation (red) and ectopic S and G2 phases by anti-CycA staining (red). Nuclei were stained with Hoechst (blue). (Scale bars, 20 μm.) (C, D, F, and G) FACS of ap-Gal4;tub-Gal80ts wings with GFP labeled cbt expression (C and D) or cbt+stg coexpression (F and G) at 30 h APF (C and F) and 44 h APF (D and G). (E) Number of cells per clone for a given genotype, with clonal induction at 0 h APF.
