Analysis of chromosome positions in the interphase nucleus of Chinese hamster cells by laser-UV-microirradiation experiments [PDF]

, 1982
Unsynchronized cells of an essentially diploid strain of female Chinese hamster cells derived from lung tissue (CHL) were laser-UV-microirradiated (=257 nm) in the nucleus either at its central part or at its periphery.

Histone H3K9 and H4 Acetylations and Transcription Facilitate the Initial CENP-AHCP−3 Deposition and De Novo Centromere Establishment in Caenorhabditis elegans Artificial Chromosomes

Epigenetics & Chromatin, 2018
Background The centromere is the specialized chromatin region that directs chromosome segregation. The kinetochore assembles on the centromere, attaching chromosomes to microtubules in mitosis.

Centromere plasmid: a new genetic tool for the study of Plasmodium falciparum. [PDF]

PLoS ONE, 2012
The introduction of transgenes into Plasmodium falciparum, a highly virulent human malaria parasite, has been conducted either by single crossover recombination or by using episomal plasmids.

Molecular cytogenetic mapping of Cucumis sativus and C. melo using highly repetitive DNA sequences [PDF]

, 2010
Chromosomes often serve as one of the most important molecular aspects of studying the evolution of species. Indeed, most of the crucial mutations that led to differentiation of species during the evolution have occurred at the chromosomal level ...

Insights into Centromere DNA Bending Revealed by the Cryo-EM Structure of the Core Centromere Binding Factor 3 with Ndc10

Cell Reports, 2018
Summary: The centromere binding factor 3 (CBF3) complex binds the third centromere DNA element in organisms with point centromeres, such as S. cerevisiae.

Structure and evolution of metapolycentromeres

Вавиловский журнал генетики и селекции
Metapolycentromeres consist of multiple sequential domains of centromeric chromatin associated with a centromere-specific variant of histone H3 (CENP-A), functioning collectively as a single centromere.

Holocentric Chromosomes Probably Do Not Prevent Centromere Drive in Cyperaceae

Frontiers in Plant Science, 2021
Centromere drive model describes an evolutionary process initiated by centromeric repeats expansion, which leads to the recruitment of excess kinetochore proteins and consequent preferential segregation of an expanded centromere to the egg during female ...

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

Transgenerational inheritance of centromere identity requires the CENP-A N-terminal tail in the C. elegans maternal germ line.

PLoS Biology, 2021
Centromere protein A (CENP-A) is a histone H3 variant that defines centromeric chromatin and is essential for centromere function. In most eukaryotes, CENP-A-containing chromatin is epigenetically maintained, and centromere identity is inherited from one

Mechanism of 2n gametes formation and centromere mapping in citrus : S02O03 [PDF]

, 2012
Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of 2n gamete formation. Two main meiotic processes are at the origin of such gametes, the first division restitution (FDR) and the second division restitution (SDR ...
