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].

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.

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

Induced chromosome pairing

California 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.

The functional organization of chromosome territories in single nuclei during zygotic genome activation [PDF]

Scientific Reports
Chromosome territories (CTs) are intricately organized and regulated within the nucleus. Despite remarkable advances in our understanding of genome packaging and gene expression, the interplay among CTs, pairing of parental homologous chromosomes, and ...

Telomeres and Subtelomeres Dynamics in the Context of Early Chromosome Interactions During Meiosis and Their Implications in Plant Breeding

Frontiers in Plant Science, 2021
Genomic architecture facilitates chromosome recognition, pairing, and recombination. Telomeres and subtelomeres play an important role at the beginning of meiosis in specific chromosome recognition and pairing, which are critical processes that allow ...

The KL system in wheat permits homoeologous crossing over between closely related chromosomes

Crop Journal, 2023
The Chinese wheat landrace Kaixianluohanmai (KL) expresses the ph-like phenotype. A major QTL, QPh.sicau-3A (syn. phKL), responsible for this effect has been mapped to chromosome arm 3AL.
