Fig. 7. Key chromatin remodelling events in Drosophila spermiogenesis. Hoechst stainings visualise the morphogenesis of the spermatid and/or sperm nuclei in the order of events after meiosis. Below is a scheme of histone degradation and Tpl94D, Mst77F and protamine deposition in comparison to general and specific histone modifications, ubiquitylation, SUMOylation, DNA breaks, expression of UbcD6 and CTCF, active RNA polymerase II and the presence of proteasomes in the nucleus.
