Current Biology, 2016 Centromeres, chromosomal regions that become physically linked to the spindle during cell division, ensure equal division of genetic material between daughter cells. They are ubiquitous and essential in eukaryotic life. In this primer, we ask the questions 'What defines a functional centromere?' and 'What do all centromeres have in common?' To address ...

Centromere Repositioning [PDF]
Genome Research, 1999 Primate pericentromeric regions recently have been shown to exhibit extraordinary evolutionary plasticity. In this paper we report an additional peculiar feature of these regions that we discovered while analyzing, by FISH, the evolutionary conservation of primate phylogenetic chromosome IX.

Holocentromeres can consist of merely a few megabase-sized satellite arrays
Nature Communications, 2023 The centromere is the chromosome region where microtubules attach during cell division. In contrast to monocentric chromosomes with one centromere, holocentric species usually distribute hundreds of centromere units along the entire chromatid.

The Birth of the Centromere [PDF]
Cell 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.

Dynamic epigenetic states of maize centromeres
Frontiers in Plant Science, 2015 The centromere is a specialized chromosomal region identified as the major constriction, upon which the kinetochore complex is formed, ensuring accurate chromosome orientation and segregation during cell division.

Stretching the rules: monocentric chromosomes with multiple centromere domains. [PDF]
PLoS Genetics, 2012 The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3.

De Novo Centromere Formation and Centromeric Sequence Expansion in Wheat and its Wide Hybrids. [PDF]
PLoS 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 Biology, 2021 The centromere is a specialized chromosomal structure essential for chromosome segregation. Centromere dysfunction leads to chromosome segregation errors and genome instability.

Centromeric transcription maintains centromeric cohesion in human cells [PDF]
Journal of Cell Biology, 2021 Centromeric transcription has been shown to play an important role in centromere functions. However, lack of approaches to specifically manipulate centromeric transcription calls into question that the proposed functions are a direct consequence of centromeric transcription.

Temporal characterization of homology-independent centromere coupling in meiotic prophase. [PDF]
PLoS ONE, 2010 Over the past thirty years several reports of the pairing or association of non-homologous centromeres during meiotic prophase have appeared in the literature.
