Longitudinal sections show that tsr RS mutants have thin retinas. One day old flies were fixed and cross-sectioned to determine the length of the retina. (A) Female flies having the construct GMR(Gal4-Pc) express Gal4-Pc in the eye but do not have a mutant phenotype because they have a wild type tsr+ allele. Weak (B) and strong (C) tsr RS mutants were found to have a thin retina when compared to the control. The yellow line shows the thickness of the retina. A lamina (L) is not found in the strongest mutant (C). Genotypes for the flies are: (A) w, P[ry+; GMR(Gal4-Pc)]2 tsrN96A/CyO female. (B) y w P[w+, tsrUAS]1/Y, P[ry+; GMR(Gal4-Pc)]1 tsrN96A/tsrN96A male. (C) y w P[w+, tsrUAS]2/w, P[ry+; GMR(Gal4-Pc)]2 tsrN96A/tsrN96A female. Anterior is on the left, posterior on the right.
