The Birth of the Centromere [PDF]

open access: yesCell Cycle, 2007
The centromere is the region of the eukaryotic chromosome that determines kinetochore formation and sister chromatid cohesion. Centromeres interact with spindle microtubules to ensure chromatid segregation during mitosis and homologous chromosome segregation during meiosis I.

Epigenetic dynamics of centromeres and neocentromeres in Cryptococcus deuterogattii.

open access: yesPLoS Genetics, 2021
Deletion of native centromeres in the human fungal pathogen Cryptococcus deuterogattii leads to neocentromere formation. Native centromeres span truncated transposable elements, while neocentromeres do not and instead span actively expressed genes.

Functional mapping of a trypanosome centromere by chromosome fragmentation identifies a 16-kb GC-rich transcriptional "strand-switch" domain as a major feature. [PDF]

open access: yes, 2005
Trypanosomatids are an ancient family that diverged from the main eukaryotic lineage early in evolution, which display several unique features of gene organization and expression.

De Novo Centromere Formation and Centromeric Sequence Expansion in Wheat and its Wide Hybrids. [PDF]

open access: yesPLoS Genetics, 2016
Centromeres typically contain tandem repeat sequences, but centromere function does not necessarily depend on these sequences. We identified functional centromeres with significant quantitative changes in the centromeric retrotransposons of wheat (CRW ...

Recent insights into mechanisms preventing ectopic centromere formation

open access: yesOpen Biology, 2021
The centromere is a specialized chromosomal structure essential for chromosome segregation. Centromere dysfunction leads to chromosome segregation errors and genome instability.

Repetitive DNA is associated with centromeric domains in Trypanosoma brucei but not Trypanosoma cruzi. [PDF]

open access: yes, 2007
BACKGROUND: Trypanosomes are parasitic protozoa that diverged early from the main eukaryotic lineage. Their genomes display several unusual characteristics and, despite completion of the trypanosome genome projects, the location of centromeric DNA has ...

Centromere Repeats: Hidden Gems of the Genome

open access: yesGenes, 2019
Satellite DNAs are now regarded as powerful and active contributors to genomic and chromosomal evolution. Paired with mobile transposable elements, these repetitive sequences provide a dynamic mechanism through which novel karyotypic modifications and ...

Mitotic centromere-associated kinesin (MCAK) : a potential cancer drug target [PDF]

open access: yes, 2011
The inability to faithfully segregate chromosomes in mitosis results in chromosome instability, a hallmark of solid tumors. Disruption of microtubule dynamics contributes highly to mitotic chromosome instability.

Comparative gene mapping in Arabidopsis lyrata chromosomes 6 and 7 and A thaliana chromosome IV: evolutionary history, rearrangements and local recombination rates [PDF]

open access: yes, 2006
We have increased the density of genetic markers on the Arabidopsis lyrata chromosomes AL6 and AL7 corresponding to the A. thaliana chromosome IV, in order to determine chromosome rearrangements between these two species, and to compare recombination ...

Linear Assembly of a Human Y Chromosome Centromere

open access: yesNature Biotechnology, 2018
The human genome reference sequence remains incomplete owing to the challenge of assembling long tracts of near-identical tandem repeats in centromeres.
