The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]

, 2019
Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Specific deletion of Cdc42 does not affect meiotic spindle organization/migration and homologous chromosome segregation but disrupts polarity establishment and cytokinesis in mouse oocytes

Molecular Biology of the Cell, 2013
Oocyte-specific deletion of Cdc42 has little effect on meiotic spindle organization and migration to the cortex but inhibits polar body emission, although homologous chromosome segregation occurs.

Mouse HFM1/Mer3 is required for crossover formation and complete synapsis of homologous chromosomes during meiosis. [PDF]

PLoS Genetics, 2013
Faithful chromosome segregation during meiosis requires that homologous chromosomes associate and recombine. Chiasmata, the cytological manifestation of recombination, provide the physical link that holds the homologs together as a pair, facilitating ...

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]

, 2005
Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

The role of OsCOM1 in homologous chromosome synapsis and recombination in rice meiosis.

The Plant Journal, 2012
COM1/SAE2 is a highly conserved gene from yeast to higher eukaryotes. Its orthologs, known to cooperate with the MRX complex (Mre11/Rad50/Xrs2), are required for meiotic DNA double-strand break (DSB) ends resection and specific mitotic DSB repair events.

GenomeFingerprinter and universal genome fingerprint analysis for systematic comparative genomics [PDF]

, 2013
How to compare whole genome sequences at large scale has not been achieved via conventional methods based on pair-wisely base-to-base comparison; nevertheless, no attention was paid to handle in-one-sitting a number of genomes crossing genetic category ...

Distance between homologous chromosomes results from chromosome positioning constraints [PDF]

Journal of Cell Science, 2010
The organization of chromosomes is important for various biological processes and is involved in the formation of rearrangements often observed in cancer. In mammals, chromosomes are organized in territories that are radially positioned in the nucleus. However, it remains unclear whether chromosomes are organized relative to each other.

Chromosome segregation in plant meiosis [PDF]

, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Checkpoints are blind to replication restart and recombination intermediates that result in gross chromosomal rearrangements [PDF]

, 2015
Replication fork inactivation can be overcome by homologous recombination, but this can cause gross chromosomal rearrangements that subsequently missegregate at mitosis, driving further chromosome instability.

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

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