TDM1 Regulation Determines the Number of Meiotic Divisions. [PDF]
PLoS Genetics, 2016 Cell cycle control must be modified at meiosis to allow two divisions to follow a single round of DNA replication, resulting in ploidy reduction. The mechanisms that ensure meiosis termination at the end of the second and not at the end of first division

Dynamic Histone H3 Modifications Regulate Meiosis Initiation via Respiration
Frontiers in Cell and Developmental Biology, 2021 Meiosis is essential for genetic stability and diversity during sexual reproduction in most eukaryotes. Chromatin structure and gene expression are drastically changed during meiosis, and various histone modifications have been reported to participate in

eLife, 2012 During meiosis, a single round of DNA replication is followed by two consecutive rounds of nuclear divisions called meiosis I and meiosis II. In meiosis I, homologous chromosomes segregate, while sister chromatids remain together.

The Cyclin B2/CDK1 Complex Conservatively Inhibits Separase Activity in Oocyte Meiosis II
Frontiers in Cell and Developmental Biology, 2021 Recently, we have reported that the cyclin B2/CDK1 complex regulates homologous chromosome segregation through inhibiting separase activity in oocyte meiosis I, which further elucidates the compensation of cyclin B2 on cyclin B1’s function in meiosis I ...

The Hop2-Mnd1 Complex and Its Regulation of Homologous Recombination
Biomolecules, 2023 Homologous recombination (HR) is essential for meiosis in most sexually reproducing organisms, where it is induced upon entry into meiotic prophase. Meiotic HR is conducted by the collaborative effort of proteins responsible for DNA double-strand break ...

Analysis of the transcriptional program governing meiosis and gametogenesis in yeast and mammals [PDF]
, 2006 During meiosis a competent diploid cell replicates its DNA once and then undergoes two consecutive divisions followed by haploid gamete differentiation.

Wellcome Open Research, 2019 Background: Meiosis produces gametes through two successive nuclear divisions, meiosis I and meiosis II. In contrast to mitosis and meiosis II, where sister chromatids are segregated, during meiosis I, homologous chromosomes are segregated. This requires

Meiosis: How Male Flies Do Meiosis [PDF]
Current Biology, 2002 In meiosis in male fruitflies, chromosome pairing events do not facilitate genetic exchange, but rather create bivalents that can be sequestered to discrete pockets of the prophase nucleus. This assignment of homologs to a common pocket likely facilitates the orientation of homologous centromeres to opposite poles.
