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

open access: goldPLoS 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].

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.

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.

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

Agent-based modeling of nuclear chromosome ensembles identifies determinants of homolog pairing during meiosis.

open access: goldPLoS Computational Biology
During meiosis, pairing of homologous chromosomes (homologs) ensures the formation of haploid gametes from diploid precursor cells, a prerequisite for sexual reproduction.

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

open access: goldPLoS 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.

Induced chromosome pairing

open access: yesCalifornia Agriculture, 1982
Not available – first paragraph follows: Success in hybridizing wild with cultivated species ultimately depends on the ability of the alien chromosomes to pair and recombine with the chromosomes of the crop species at meiosis.

Protein phosphatase 4 promotes chromosome pairing and synapsis, and contributes to maintaining crossover competence with increasing age. [PDF]

open access: yesPLoS Genetics, 2014
Prior to the meiotic divisions, dynamic chromosome reorganizations including pairing, synapsis, and recombination of maternal and paternal chromosome pairs must occur in a highly regulated fashion during meiotic prophase.
