Chromosome Pairing in Polyploid Grasses [PDF]

open access: yesFrontiers in Plant Science, 2020
Polyploids are species in which three or more sets of chromosomes coexist. Polyploidy frequently occurs in plants and plays a major role in their evolution.

Chromosome pairing: a hidden treasure no more. [PDF]

open access: yesPLoS Genetics, 2012
Many generations of biologists have been intrigued by the myriad structures that eukaryotic chromosomes can adopt and have questioned how their form relates to function [1], [2]. One organizational state that chromosomes adopt is pairing in a homology-dependent manner [3]–[8].

Differing requirements for RAD51 and DMC1 in meiotic pairing of centromeres and chromosome arms in Arabidopsis thaliana. [PDF]

open access: yesPLoS Genetics, 2012
During meiosis homologous chromosomes pair, recombine, and synapse, thus ensuring accurate chromosome segregation and the halving of ploidy necessary for gametogenesis.

Modeling cell biological features of meiotic chromosome pairing to study interlock resolution. [PDF]

open access: yesPLoS Computational Biology, 2022
During meiosis, homologous chromosomes become associated side by side in a process known as homologous chromosome pairing. Pairing requires long range chromosome motion through a nucleus that is full of other chromosomes.

The courtship choreography of homologous chromosomes: timing and mechanisms of DSB-independent pairing [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2023
Meiosis involves deep changes in the spatial organisation and interactions of chromosomes enabling the two primary functions of this process: increasing genetic diversity and reducing ploidy level.

Chromosome Pairing in Hybrid Progeny between Triticum aestivum and Elytrigia elongata [PDF]

open access: yesFrontiers in Plant Science, 2017
In this study, the intergeneric hybrids F1, F2, BC1F1, BC1F2, and BC2F1 from Elytrigia elongata and Triticum aestivum crosses were produced to study their chromosome pairing behavior. The average E. elongata chromosome configuration of the two F1 hybrids

Mechanics and dynamics of X-chromosome pairing at X inactivation. [PDF]

open access: yesPLoS Computational Biology, 2008
At the onset of X-chromosome inactivation, the vital process whereby female mammalian cells equalize X products with respect to males, the X chromosomes are colocalized along their Xic (X-inactivation center) regions.

Chromosome painting reveals asynaptic full alignment of homologs and HIM-8-dependent remodeling of X chromosome territories during Caenorhabditis elegans meiosis. [PDF]

open access: yesPLoS Genetics, 2011
During early meiotic prophase, a nucleus-wide reorganization leads to sorting of chromosomes into homologous pairs and to establishing associations between homologous chromosomes along their entire lengths.

Meiotic chromosome pairing is promoted by telomere-led chromosome movements independent of bouquet formation. [PDF]

open access: yesPLoS Genetics, 2012
Chromosome pairing in meiotic prophase is a prerequisite for the high fidelity of chromosome segregation that haploidizes the genome prior to gamete formation. In the budding yeast Saccharomyces cerevisiae, as in most multicellular eukaryotes, homologous

Somatic pairing of chromosome 19 in renal oncocytoma is associated with deregulated EGLN2-mediated [corrected] oxygen-sensing response. [PDF]

open access: yesPLoS Genetics, 2008
Chromosomal abnormalities, such as structural and numerical abnormalities, are a common occurrence in cancer. The close association of homologous chromosomes during interphase, a phenomenon termed somatic chromosome pairing, has been observed in ...
