Piwi and piRNAs repress transcription of aberrant rRNA genes containing retrotransposon fragments

The paper shows that Piwi and piRNAs repress transcription of defective rRNA genes with truncated retrotransposon insertions in Drosophila ovaries, preventing aberrant rRNA accumulation.

Nucleoporin Elys attaches peripheral chromatin to the nuclear pores in interphase nuclei

The paper identifies Elys as a nucleoporin linking peripheral chromatin to nuclear pores in interphase nuclei and shows its role in chromatin organization and gene regulation.

A study of the expression of germline-specific paralogs of the ubiquitously expressed NAC complex revealed their association with centrosomes

The paper investigates germline-specific NAC paralogs in Drosophila, showing their association with centrosomes and their role in proteostasis and fertility.

Exact breakpoints of In(1)wm4 rearrangement

The paper determines the exact euchromatic and heterochromatic breakpoints of the In(1)wm4 rearrangement in Drosophila using nanopore sequencing.

Key role of piRNAs in telomeric chromatin maintenance and telomere nuclear positioning in Drosophila germline

This study shows that piRNAs are essential for telomere chromatin maintenance and nuclear positioning in Drosophila germline, with implications for heterochromatic component stability.
