Synaptonemal complex components promote centromere pairing in pre-meiotic germ cells. [PDF]
PLoS Genetics, 2013 Mitosis and meiosis are two distinct cell division programs. During mitosis, sister chromatids separate, whereas during the first meiotic division, homologous chromosomes pair and then segregate from each other.

Characterization of two full-sized P elements from Drosophila sturtevanti and Drosophila prosaltans
Genetics and Molecular Biology, 2004 Previously, only partial P element sequences have been reported in the saltans group of Drosophila but in this paper we report two complete P element sequences from Drosophila sturtevanti and Drosophila prosaltans.

The SET-domain protein SUVR5 mediates H3K9me2 deposition and silencing at stimulus response genes in a DNA methylation-independent manner. [PDF]
PLoS Genetics, 2012 In eukaryotic cells, environmental and developmental signals alter chromatin structure and modulate gene expression. Heterochromatin constitutes the transcriptionally inactive state of the genome and in plants and mammals is generally characterized by ...

Extensive karyotype variability of African fish genus Nothobranchius (Cyprinodontiformes)
Comparative Cytogenetics, 2018 Karyotypes of 65 species of the genus Nothobranchius Peters, 1868 were reviewed and of those 35 examined first time. The results of present study have shown that fishes of the genus Nothobranchius possessed highly diverse karyotypes.

Comparative Cytogenetics, 2017 Despite many studies, the impact of chromosome rearrangements on gene flow between chromosome races of the common shrew (Sorex araneus Linnaeus, 1758) remains unclear. Interracial hybrids form meiotic chromosome complexes that are associated with reduced
