Fast centromeric repeat turnover provides a glimpse into satellite DNA evolution in Nothobranchius annual killifishes

Anna Voleníková, Karolína Lukšíková, Pablo Mora…·Alexandr Sember

The paper investigates satDNA evolution in Nothobranchius killifishes, identifying centromere-associated repeats and suggesting centromere drive and spindle polarity reversal as factors in karyotype change.

Formation of hemiclonal reproduction and hybridogenesis in Pelophylax water frogs studied with species-specific cytogenomic probes

Lukáš Choleva, Marie Doležálková‐Kaštánková, Veronika Labajová…·Dmitrij Dedukh

This study investigates the transition to asexual reproduction in water frogs through hybridogenesis, using cytogenomic probes to show DNA elimination and gametogenic modifications in F1 hybrids.
