Developmental conversion of the nucleolus into an RNA Polymerase II transcriptional platform in Drosophila spermatocytes

Jaclyn M. Fingerhut, Jun I. Park, Rebecca Y Li, Romain Lannes, Archana Ashok, Yukiko M Yamashita

The paper shows that in Drosophila spermatocytes, nucleoli convert into NLBs that serve as platforms for RNA Polymerase II transcription of Y-linked fertility genes.

Deregulation of Y-linked protamine-like genes in sex chromosome-biased spermatid demise

Jun I. Park, George W. Bell, Yukiko M Yamashita

The paper identifies Y-linked protamine-like genes as meiotic drivers in Drosophila by showing they cause nuclear decompaction and biased demise of X-bearing sperm through dominant-negative effects.
