Structural plasticity of the living kinetochore [PDF]
, 2017 The kinetochore is a large, evolutionarily conserved protein structure that connects chromosomes with microtubules. During chromosome segregation, outer kinetochore components track depolymerizing ends of microtubules to facilitate the separation of ...

Heterochromatin and RNAi regulate centromeres by protecting CENP-A from ubiquitin-mediated degradation. [PDF]
PLoS Genetics, 2018 Centromere is a specialized chromatin domain that plays a vital role in chromosome segregation. In most eukaryotes, centromere is surrounded by the epigenetically distinct heterochromatin domain. Heterochromatin has been shown to contribute to centromere

HIM-10 is required for kinetochore structure and function on Caenorhabditis elegans holocentric chromosomes. [PDF]
, 2001 Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

The micronucleus assay as a biological dosimeter of in vivo ionising radiation exposure [PDF]
, 2010 Biological dosimetry, based on the analysis of micronuclei (MN) in the cytokinesis-block micronucleus (CBMN) assay can be used as an alternative method for scoring dicentric chromosomes in the field of radiation protection.

Atypical centromeres in plants – what they can tell us
Frontiers in Plant Science, 2015 The centromere, visible as the primary constriction of condensed metaphase chromosomes, is a defined chromosomal locus essential for genome stability. It mediates transient assembly of a multi-protein complex, the kinetochore, which enables interaction ...

Amplification and adaptation of centromeric repeats in polyploid switchgrass species. [PDF]
, 2018 Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats from a single satellite repeat family. Why centromeres are dominated by a single satellite repeat and how the satellite repeats originate and evolve are among the most

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

Sequential assembly of centromeric proteins in male mouse meiosis. [PDF]
PLoS Genetics, 2009 The assembly of the mitotic centromere has been extensively studied in recent years, revealing the sequence and regulation of protein loading to this chromosome domain. However, few studies have analyzed centromere assembly during mammalian meiosis. This

Principles of meiotic chromosome assembly revealed in S. cerevisiae [PDF]
, 2019 During meiotic prophase, chromosomes organise into a series of chromatin loops emanating from a proteinaceous axis, but the mechanisms of assembly remain unclear.
