Loss of Graf selectively disrupts β-lobe morphology. Representative confocal z-projections of adult wild-type and Graf1/Df brains expressing UAS-mCD8-GFP under the control of MB cell-type specific GAL4 drivers to label all α/β (a; c739), α′/β′ (b; c305a), and γ (c; 1471) neurons (n = 30 brains). Brains were double stained with anti-GFP (green) and anti-FasII (red) antibodies. Note that β lobes in Graf mutants display midline crossing defects (arrows), whereas the α, α′, β′, and γ lobes show no obvious morphological defect. Arrowheads indicate the brain midline.
