Sequential Loading of Cohesin Subunits during the First Meiotic Prophase of Grasshoppers [PDF]

open access: yes, 2007
A previous version of this article appeared as an Early Online Release on January 2, 2007 (doi:10.1371/journal.pgen.0030028.eor).The cohesin complexes play a key role in chromosome segregation during both mitosis and meiosis.

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 ...

Dynamic Architecture of DNA Repair Complexes and the Synaptonemal Complex at Sites of Meiotic Recombination

open access: yesCell, 2017
Meiotic double-strand breaks (DSBs) are generated and repaired in a highly regulated manner to ensure formation of crossovers (COs) while also enabling efficient non-CO repair to restore genome integrity. Here we use Structured-Illumination Microscopy to

Telomeres cluster de novo before the initiation of synapsis: a three-dimensional spatial analysis of telomere positions before and during meiotic prophase. [PDF]

open access: yes, 1997
We have analyzed the progressive changes in the spatial distribution of telomeres during meiosis using three-dimensional, high resolution fluorescence microscopy.

DNA repair mechanisms and gametogenesis [PDF]

open access: yes, 2001
In mammals, there is a complex and intriguing relationship between DNA repair and gametogenesis. DNA repair mechanisms are involved not only in the repair of different types of DNA damage in developing germline cells, but ...

Crossover recombination and synapsis are linked by adjacent regions within the N terminus of the Zip1 synaptonemal complex protein

open access: yesbioRxiv, 2018
Accurate chromosome segregation during meiosis relies on the prior establishment of at least one crossover recombination event between homologous chromosomes, which is often associated with the meiosis-specific MutSγ complex.

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.

Meiotic recombination modulates the structure and dynamics of the synaptonemal complex during C. elegans meiosis

open access: yesbioRxiv, 2017
During meiotic prophase, a structure called the synaptonemal complex (SC) assembles at the interface between aligned pairs of homologous chromosomes, and crossover recombination events occur between their DNA molecules.
