Fig. 5. Dpp signaling and Rst work in opposition in the Drosophila
pupal retina. Genetic interactions between dpp pathway components
and rst. (A-F) Scanning electron micrographs of adult eyes
taken at (A-C) 180x and (D-F) 800x. (G-I) 42 hours APF
retinas stained with anti-Armadillo antibody. Removing a single functional
genomic copy of tkv (B,E,H) or Mad (C,F,I) suppressed the
rough eye phenotype of rst3 mutants (A,D,G).
