Chromosome Pairing in Polyploid Grasses [PDF]
Frontiers 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]
PLoS 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 Hybrid Progeny between Triticum aestivum and Elytrigia elongata [PDF]
Frontiers 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

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

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

PAR-TERRA directs homologous sex chromosome pairing. [PDF]
Nat Struct Mol Biol, 2017 In mammals, homologous chromosomes rarely pair outside meiosis. One exception is the X chromosome, which transiently pairs during X-chromosome inactivation (XCI). How two chromosomes find each other in 3D space is not known.

Moving and stopping: Regulation of chromosome movement to promote meiotic chromosome pairing and synapsis. [PDF]
Nucleus, 2017 Meiosis is a specialized cellular division occurring in organisms capable of sexual reproduction that leads to the formation of gametes containing half of the original chromosome number.

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

Meiotic cohesin-based chromosome structure is essential for homologous chromosome pairing in Schizosaccharomyces pombe. [PDF]
Chromosoma, 2016 Chromosome structure is dramatically altered upon entering meiosis to establish chromosomal architectures necessary for the successful progression of meiosis-specific events. An early meiotic event involves the replacement of the non-SMC mitotic cohesins

Partial preferential chromosome pairing is genotype dependent in tetraploid rose
Plant Journal, 2017 It has long been recognised that polyploid species do not always neatly fall into the categories of auto- or allopolyploid, leading to the term 'segmental allopolyploid' to describe everything in between.
