Separase Is Required for Homolog and Sister Disjunction during Drosophila melanogaster Male Meiosis, but Not for Biorientation of Sister Centromeres.

PLoS Genetics, 2016
Spatially controlled release of sister chromatid cohesion during progression through the meiotic divisions is of paramount importance for error-free chromosome segregation during meiosis.

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

Kinetochore inactivation by expression of a repressive mRNA. [PDF]

, 2017
Differentiation programs such as meiosis depend on extensive gene regulation to mediate cellular morphogenesis. Meiosis requires transient removal of the outer kinetochore, the complex that connects microtubules to chromosomes.

Meiosis I chromosome segregation is established through regulation of microtubule–kinetochore interactions

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 ...

Evidence that MEK1 positively promotes interhomologue double-strand break repair [PDF]

, 2010
During meiosis there is an imperative to create sufficient crossovers for homologue segregation. This can be achieved during repair of programmed DNA double-strand breaks (DSBs), which are biased towards using a homologue rather than sister chromatid as ...

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

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 ...

Cold-induced male meiotic restitution in Arabidopsis thaliana is not mediated by GA-DELLA signaling [PDF]

, 2018
Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis.
