Plant centromeres

Current Opinion in Plant Biology, 2017
Plant centromeres, which are determined epigenetically by centromeric histone 3 (CENH3) have revealed surprising structural diversity, ranging from the canonical monocentric seen in vertebrates, to polycentric, and holocentric. Normally stable, centromeres can change position over evolutionary times or upon genomic stress, such as when chromosomes are ...

Plant Centromeres

2008
Plant centromeres are generally composed of tandem arrays of simple repeats that are typical of a particular species, but that evolve rapidly. Centromere specific retroelements are also present. These arrays associate with a centromere specific variant of histone H3 that anchors the site of the kinetochore.

Centromerization

Trends in Cell Biology, 2000
Centromere formation is a complex process that involves the packaging of DNA into a centromere-unique chromatin, chemical modification and the seeding of kinetochore and associated proteins. The early steps in this process, in which a chromosomal region is marked for centromerization (that is, to become resolutely committed to centromere formation ...

Centromere spreading and centromeric aberrations in ovarian tumors

Cancer Genetics and Cytogenetics, 1995
Centromere spreading (CS) of chromosomes and high occurrence of aberrations at centromeric region were observed in two papillary serous cystadenocarcinomas and one borderline papillary serous cystadenoma of the ovary. In the borderline tumor, CS of chromosome 12, trisomy of which had been reported as the sole abnomaly in benign ovarian tumors, was seen

Yeast centromeres

Yeast, 1987
Significant progress has been made toward understanding the roles played by conserved centromere DNA sequences in both mitotic and meiotic chromosome segregation. We are just beginning to formulate a picture of what a yeast kinetochore actually looks like and what components other than CEN DNA are necessary for function.

Sister chromatid exchange in the centromere and centromeric area

Human Genetics, 1983
Central and peripheral sister chromatid exchanges (SCE) were evaluated separately in human phytohemagglutinin (PHA)-stimulated lymphocytes after culture for 72 h in 5-bromodeoxyuridine (BrdU) containing medium. At the same time, the length of chromosome No.

The Centromere Paradox: Stable Inheritance with Rapidly Evolving DNA

Science, 2001
Every eukaryotic chromosome has a centromere, the locus responsible for poleward movement at mitosis and meiosis. Although conventional loci are specified by their DNA sequences, current evidence favors a chromatin-based inheritance mechanism for ...

Silence of the centromeres – not

Trends in Biotechnology, 2004
Centromeres are a conundrum; although many proteins associated with centomeres are conserved from yeast to humans, the underlying DNA sequence is not. A proposed solution to this problem is that an epigenetic, largely heterochromatic, state be imposed by these proteins.

Centromere dynamics

Current Opinion in Genetics & Development, 2007
At the foundation of all eukaryotic kinetochores is a unique histone variant, known as CenH3 (centromere histone H3). We are starting to identify the histone chaperones responsible for CenH3 deposition at centromere DNA, and the mechanisms that restrict CenH3 from chromosome arms.
