Characterization of meiotic chromosome behavior in the autopolyploid Saccharum spontaneum reveals preferential chromosome pairing without distinct DNA sequence variation

open access: yesCrop Journal, 2023
Autopolyploidy and allopolyploidy may represent an evolutionary advantage and are more common in plants than assumed. However, less attention has been paid to autopolyploidy than to allopolyploidy, and its evolutionary consequences are largely unclear ...

Site-Specific Sequence Exchange Between Homologous and Non-homologous Chromosomes [PDF]

open access: yesFrontiers in Plant Science, 2022
Transgene integration typically takes place in an easy-to-transform laboratory variety before the transformation event is introgressed through backcrosses to elite cultivars. As new traits are added to existing transgenic lines, site-specific integration can stack new transgenes into a previously created transgenic locus.

Dispersive forces and resisting spot welds by alternative homolog conjunction govern chromosome shape in Drosophila spermatocytes during prophase I.

open access: yesPLoS Genetics, 2022
The bivalent chromosomes that are generated during prophase of meiosis I comprise a pair of homologous chromosomes. Homolog pairing during prophase I must include mechanisms that avoid or eliminate entanglements between non-homologous chromosomes.

Dynamics of rye chromosome 1R regions with high or low crossover frequency in homology search and synapsis development. [PDF]

open access: yesPLoS ONE, 2012
In many organisms, homologous pairing and synapsis depend on the meiotic recombination machinery that repairs double-strand DNA breaks (DSBs) produced at the onset of meiosis.

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

open access: yes, 1984
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

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.

Natural Chromosome-Chromid Fusion across rRNA Operons in a Burkholderiaceae Bacterium

open access: yesMicrobiology Spectrum, 2022
Chromids (secondary chromosomes) in bacterial genomes that are present in addition to the main chromosome appear to be evolutionarily conserved in some specific bacterial groups.

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

open access: yes, 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. The mechanism inducing recognition
