...Katja Röper During oogenesis in Drosophila an organelle called the fusome plays a crucial role in germline cyst development and oocyte selection. The fusome consists of cytoskeletal proteins and intracellular membranes and, whereas many cytoskeletal components have been characterized, the nature...

...-actin to these sites at particular times of the cell cycle. Our studies on the relationships between anillin and F-actin have also provided detailed information on the organization and development of the male fusome. In postmeiotic stages the overall amount of anillin detectable...

..., anillin is lost from mature ring canals and filamentous actin is a major component. In both males and females, a highly branched vesicular structure, termed the fusome, interconnects developing germ cells via the ring canals and is thought to coordinate mitotic germ cell divisions. We show that, in males...
