The courtship choreography of homologous chromosomes: timing and mechanisms of DSB-independent pairing

Frontiers in Cell and Developmental Biology, 2023
Meiosis involves deep changes in the spatial organisation and interactions of chromosomes enabling the two primary functions of this process: increasing genetic diversity and reducing ploidy level.

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

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]

, 2012
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...

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 ...

Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

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.

Comparative Chromosome Maps of Neotropical Rodents Necromys lasiurus and Thaptomys nigrita (Cricetidae) Established by ZOO-FISH [PDF]

, 2011
This work presents chromosome homology maps between Mus musculus (MMU) and 2 South American rodent species from the Cricetidae group: Necromys lasiurus (NLA, 2n = 34) and Thaptomys nigrita (TNI, 2n = 52), established by ZOO-FISH using mouse chromosome ...
