Figure 7


Fig. 7. Pros{alpha}6T1 mutant testes show abnormalities in nuclear bundles. Wild-type or Pros{alpha}6T1 spermatid nuclei stained with TO-PRO3. (A) Wild-type nuclei are long, fully condensed and remain in register. (B) Some of the Pros{alpha}6T1 nuclei are not fully condensed and they are often scattered. (C) Spermatid nuclei of the mutant are often contorted and frequently form circles (arrow). (D) Proportion of normal, scattered and curled spermatid nuclear bundles in young (black bars) versus old (hatched bars) flies. Scale bars: 20 µm.
