Mechanics of meiosis [PDF]

open access: yesHereditas, 2009
The present paper reviews our observations on the premeiotic DNA replication in Lilium and on the morphology and behaviour of chromosomes during the meiotic prophase in Schizophyllum, Lilium, Drosophila, Bombyx and Homo as revealed by three-dimensional reconstructions of synaptonemal complexes (SC).

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]

open access: yes, 2011
During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

Cohesin-interacting protein WAPL-1 regulates meiotic chromosome structure and cohesion by antagonizing specific cohesin complexes

open access: yeseLife, 2016
Wapl induces cohesin dissociation from DNA throughout the mitotic cell cycle, modulating sister chromatid cohesion and higher-order chromatin structure.

How to halve ploidy : lessons from budding yeast meiosis [PDF]

open access: yes, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Meiotic progression in arabidopsis is governed by complex regulatory interactions between SMG7, TDM1, and the meiosis I-specific cyclin TAM [PDF]

open access: yes, 2010
International audienceMeiosis is a modified cell division that produces four haploid nuclei from a single diploid cell in two rounds of chromosome segregation.

Homolog pairing during meiosis : dyneins on the move [PDF]

open access: yes, 2010
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]

open access: yes, 2015
Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

Focus on Meiosis [PDF]

open access: yesReproduction, 2005
The past five years have seen the dawn of an era of illumination in our understanding of how vertebrate meiosis is regulated. Much of the foundation for recent progress came from the enormous advances in elucidating the molecular regulation of mitotic cell division and yeast meiosis (reviewed in Uhlmann 2001, Petronczki et al.

The cyclin-A CYCA1;2/TAM is required for the meiosis I to meiosis II transition and cooperates with OSD1 for the prophase to first meiotic division transition. [PDF]

open access: yesPLoS Genetics, 2010
Meiosis halves the chromosome number because its two divisions follow a single round of DNA replication. This process involves two cell transitions, the transition from prophase to the first meiotic division (meiosis I) and the unique meiosis I to ...

Tackling Plant Meiosis: From Model Research to Crop Improvement

open access: yesFrontiers in Plant Science, 2018
Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division
