Progeny obtained from homozygous csule00797
mothers are sterile and agametic. Embryos from csule00797
mothers are devoid of pole cells.
animals are completely viable and survive to adulthood.
mutants display no obvious locomotor defects at either larval or adult stages. There is no obvious degeneration or disorganisation of thoracic musculature in adult csule00797
mutant testes contain fewer sperm bundles than in wild-type, and display a dramatic loss of organisation among the sperm bundles. The average bundle contains far fewer spermatid nuclei than in the wild-type control. The seminal vesicles of csule00797
males are almost completely devoid of sperm.
females are fertile, albeit with slightly reduced fecundity. When crossed to wild-type males, approximately 65% of the embryos hatch into larvae that develop normally into adult flies. However, all of these flies are agametic, and therefore sterile. The remaining 35% of the embryos display a variety of segmentation defects, as compared to wild-type. All embryos are completely devoid of pole cells.
