Overexpression of Amun suppresses the GMR>DeltaWT/+ cone cell phenotype. (A–C) Twenty-four-hour APF retinas stained with anti-Cut antibody (green) to detect cone cells. (A) A GMR>DeltaWT/+ retina exhibits a disorganized array of ommatidia with an average of 3.34 cone cells/ommatidium. (B) A P{XP}d03329/+;GMR>DeltaWT/+ retina exhibits suppression of the GMR>DeltaWT/+ cone cell phenotype, increasing the average to 3.5 cone cells/ommatidium. (C) A GMR>DeltaWT/+;UAS-AmunWT/+ retina exhibits greater suppression of the GMR>DeltaWT/+ cone cell phenotype, as compared to B, increasing the average to 3.73 cone cells/ommatidium (P < 0.005). (D) The proportional representation of ommatidia with two, three, four, or five cone cells. The percentage of ommatidia with four cone cells is greater for P{XP}d03329/+;GMR>DeltaWT/+ and GMR>DeltaWT/+;UAS-AmunWT/+ retinas than for GMR>DeltaWT/+ retinas. An asterisk denotes a statistically significant difference (P < 0.005) in average cone cells per ommatidium, as compared to GMR>DeltaWT/+.
