Fig. 1. Src64^KO fertility defects. (A) Confocal projections of stage 10 egg chambers stained with phalloidin (green) to visualize filamentous actin and anti-Src64 (red) to visualize Src64 protein. Genotypes are abbreviated. (B) Immunoblot of ovary extracts using anti-Src64 antibody or anti-BicD (loading control). (C) Egg lay rates for wild-type (WT) females versus Src64¹⁷ or Src64^KO expressed as the number of eggs laid/fly/hour. (D) Hatch rates for WT versus Src64 mutants. Scale bars: 10 µm.
