PIWI-interacting RNAs (piRNAs) are a class of small non-coding RNAs that associate with
proteins of the PIWI clade of the Argonaute family. First identified in animal germ line cells …

Simple non-coding tandem repeats known as satellite DNA are observed widely across
eukaryotes. These repeats occupy vast regions at the centromere and pericentromere of …

RNA interference systems depend on the synthesis of small RNA precursors whose
sequences define the target spectrum of these silencing pathways. The Drosophila …

Gametogenesis is vulnerable to selfish genetic elements that bias their transmission to the
next generation by cheating meiosis. These so-called meiotic drivers are widespread in …

Large genome structural variations can impact genome regulation and integrity. Repeat-rich
regions like pericentric heterochromatin are vulnerable to structural rearrangements …

Tandemly repeated satellite DNAs are major components of centromeres and
pericentromeric heterochromatin which are crucial chromosomal elements responsible for …

In the genus Talpa a new species, named Talpa aquitania, has been recently described.
Only cytogenetic data are available for the nuclear genome of this species. In this work, we …

Segregation Distorter (SD) is a male meiotic drive system in Drosophila melanogaster.
Males heterozygous for a selfish SD chromosome rarely transmit the homologous SD+ …

Centromeres are chromosomal regions essential for coordinating chromosome segregation
during cell division. While centromeres are defined by the presence of a centromere-specific …

Abundant tandemly repeated satellite DNA is present in most eukaryotic genomes. Previous
limitations including a pervasive view that it was uninteresting junk DNA, combined with …
