Meiotic double strand breaks repair in sexually reproducing eukaryotes: We are not all equal. [PDF]

open access: yes, 2012
The defining event of meiosis is prophase-I, during which the maternal and paternal chromosome find each other in the nucleus, pair, and align in a process called “synapses of the homologues”. Their faithful segregation during the first meiotic division (

CDK2 regulates nuclear envelope protein dynamics and telomere attachment in mouse meiotic prophase [PDF]

open access: yes, 2015
In most organisms, telomeres attach to the nuclear envelope at the onset of meiosis to promote the crucial processes of pairing, recombination and synapsis during prophase I.

Pushing the (nuclear) envelope into meiosis. [PDF]

open access: yes, 2013
A recent study shows that a short isoform of a mammalian nuclear lamin is important for homologous chromosome interactions during meiotic prophase in ...

Meiotic DSB patterning: A multifaceted process [PDF]

open access: yes, 2016
Meiosis is a specialized two-step cell division responsible for genome haploidization and the generation of genetic diversity during gametogenesis. An integral and distinctive feature of the meiotic program is the evolutionarily conserved initiation of ...

Cytomixis doesn’t induce obvious changes in chromatin modifications and programmed cell death in tobacco male meiocytes

open access: yesFrontiers in Plant Science, 2015
Cytomixis is a poorly studied process of nuclear migration between plant cells. It is so far unknown what drives cytomixis and what is the functional state of the chromatin migrating between cells.

Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of Robertsonian heterozygotes of Mus domesticus

open access: yesBiological Research, 2017
Background The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements.

Dynamic reorganization of the genome shapes the recombination landscape in meiotic prophase. [PDF]

open access: yes, 2019
In meiotic prophase, chromosomes are organized into compacted loop arrays to promote homolog pairing and recombination. Here, we probe the architecture of the mouse spermatocyte genome in early and late meiotic prophase using chromosome conformation ...

The conserved ATPase PCH-2 controls the number and distribution of crossovers by antagonizing their formation in Caenorhabditis elegans

open access: yeseLife
Meiotic crossover recombination is essential for both accurate chromosome segregation and the generation of new haplotypes for natural selection to act upon. This requirement is known as crossover assurance and is one example of crossover control.

Analysis of the synaptonemal complex of the nine-banded armadillo, Dasypus novemcinctus

open access: yesGenetics and Molecular Biology, 2000
The synaptonemal complex (SC) of three specimens of the nine-banded armadillo (Dasypus novemcinctus) was analyzed. Thirty-two bivalents (2n = 64) were observed, 31 of them being autosomes and one an XY sexual bivalent.
