Sister centromere fusion is a process unique to meiosis that promotes co-orientation of the sister kinetochores, ensuring they attach to microtubules from the same pole during metaphase I.

Structure and Stability of Telocentric Chromosomes in Wheat. [PDF]
In most eukaryotes, centromeres assemble at a single location per chromosome. Naturally occurring telocentric chromosomes (telosomes) with a terminal centromere are rare but do exist.

The Role of Human Centromeric RNA in Chromosome Stability
Chromosome instability is a hallmark of cancer and is caused by inaccurate segregation of chromosomes. One cellular structure used to avoid this fate is the kinetochore, which binds to the centromere on the chromosome.

DNA methylation and chromosomal copy number profiling have recently become essential for tumor diagnostics. The open‐source tool Mepylome enables this task in clinical routine. It combines several machine learning strategies and allows users to interactively examine respective data through an intuitive graphical interface. Running up to 65 times faster

Centromere mechanical maturation during mammalian cell mitosis
During mitosis, tension at the centromere occurs from the spindle but the role of centromere mechanics in controlling metaphase tension is poorly understood.

The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4KMT1. This recruits multiple heterochromatin proteins, including Swi6 and Chp1, to form a rigid centromere and ensure accurate chromosome ...

Alpha-satellite RNA transcripts are repressed by centromere–nucleolus associations
Although originally thought to be silent chromosomal regions, centromeres are instead actively transcribed. However, the behavior and contributions of centromere-derived RNAs have remained unclear.

Pan-centromere reveals widespread centromere repositioning of soybean genomes
Centromere repositioning refers to a de novo centromere formation at another chromosomal position without sequence rearrangement. This phenomenon was frequently encountered in both mammalian and plant species and has been implicated in genome evolution and speciation.

Phylogenetic systematics of Juncaceae
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...

Temporal characterization of homology-independent centromere coupling in meiotic prophase.
BackgroundOver the past thirty years several reports of the pairing or association of non-homologous centromeres during meiotic prophase have appeared in the literature.
