Stretching the rules: monocentric chromosomes with multiple centromere domains. [PDF]

open access: yesPLoS 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.

EWSR1 maintains centromere identity

open access: yesCell Reports, 2023
Summary: The centromere is essential for ensuring high-fidelity transmission of chromosomes. CENP-A, the centromeric histone H3 variant, is thought to be the epigenetic mark of centromere identity.

Chromosome Y centromere array deletion leads to impaired centromere function. [PDF]

open access: yesPLoS ONE, 2014
The centromere is an essential chromosomal structure that is required for the faithful distribution of replicated chromosomes to daughter cells. Defects in the centromere can compromise the stability of chromosomes resulting in segregation errors.

Centromere Repositioning [PDF]

open access: yesGenome 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.

Centromere domain organization and histone modifications [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2002
Centromere function requires the proper coordination of several subfunctions, such as kinetochore assembly, sister chromatid cohesion, binding of kinetochore microtubules, orientation of sister kinetochores to opposite spindle poles, and their movement ...

Immunohistochemistry as a tool for identifying PDGFRA amplification in central nervous system tumors. [PDF]

open access: yesBrain Pathol
PDGFRA gene amplification is now recognized as a diagnostically and prognostically relevant molecular alteration in central nervous system tumors. Herein, we demonstrated that PDGFRA immunohistochemistry is a highly specific and sensitive biomarker for identifying PDGFRA amplification and should be part of the neuropathologist's routine panel of ...

The Rise of Plant Pan-Genomes: From Genome Variation to Predictive Breeding. [PDF]

open access: yesAdv Genet (Hoboken)
Plant pan‐genomics is shifting from genome variation discovery to understanding how diversity drives biological function and breeding value. Future advances will integrate SV/PAV, haplotype diversity, super pan‐genomes, pan‐omics, 3D genomics, and AI to transform genomic resources into predictive breeding strategies.

Only the Rye Derived Part of the 1BL/1RS Hybrid Centromere Incorporates CENH3 of Wheat

open access: yesFrontiers in Plant Science, 2021
The precise assembly of the kinetochore complex at the centromere is epigenetically determined by substituting histone H3 with the centromere-specific histone H3 variant CENH3 in centromeric nucleosomes.

The cotton centromere contains a Ty3-gypsy-like LTR retroelement. [PDF]

open access: yesPLoS ONE, 2012
The centromere is a repeat-rich structure essential for chromosome segregation; with the long-term aim of understanding centromere structure and function, we set out to identify cotton centromere sequences. To isolate centromere-associated sequences from

Centromeres [PDF]

open access: yesCurrent 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 ...
