Precise spatiotemporal regulation of gene expression is of paramount importance for
eukaryotic development. The maternal-to-zygotic transition (MZT) during early …

Male infertility has become an increasingly severe global health issue, with its incidence
significantly rising over the past few decades. This paper delves into the crucial role of …

Although there is extensive information about sperm nuclear basic proteins (SNBP) in
vertebrates, there is, by comparison, very little information in Arthropoda. This study aims to …

Insects are the largest group of animals when it comes to the number and diversity of
species. Yet, with the exception of Drosophila, no information is currently available on the …

Paternal chromosomes undergo a radical conformational change during sperm
development, compacting 20-to 200-fold (,). Compaction is achieved by the replacement of …

New genes arise through a variety of evolutionary processes and provide raw material for
adaptation in the face of both natural and sexual selection. De novo evolved genes emerge …

While spermatogenesis has been extensively characterized in the Drosophila melanogaster
model system, very little is known about the genes required for fly sperm entry into eggs. We …

This chapter provides an introduction on general characteristics and properties of the
dominant life form—unicellular organisms, demonstrated by a graphic presentation of …
