LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]
, 2015 Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

The meiosis-specific Cdc20 family-member Ama1 promotes binding of the Ssp2 activator to the Smk1 MAP kinase. [PDF]
, 2018 Smk1 is a meiosis-specific MAP kinase (MAPK) in budding yeast that is required for spore formation. It is localized to prospore membranes (PSMs), the structures that engulf haploid cells during meiosis II (MII).

Molecular Cell, 2003 Degradation of mitotic cyclins is critical for exit from mitosis. Recent studies in budding yeast address the role of cyclin degradation in meiosis. Cyclin stabilization in meiosis I interferes with anaphase I spindle disassembly but, surprisingly, does not halt progression into meiosis II.

Tackling Plant Meiosis: From Model Research to Crop Improvement
Frontiers 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

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]
PLoS 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 ...

MeiosisOnline: A Manually Curated Database for Tracking and Predicting Genes Associated With Meiosis
Frontiers in Cell and Developmental Biology, 2021 Meiosis, an essential step in gametogenesis, is the key event in sexually reproducing organisms. Thousands of genes have been reported to be involved in meiosis. Therefore, a specialist database is much needed for scientists to know about the function of

A Computational Approach to Estimating Nondisjunction Frequency in Saccharomyces cerevisiae. [PDF]
, 2016 Errors segregating homologous chromosomes during meiosis result in aneuploid gametes and are the largest contributing factor to birth defects and spontaneous abortions in humans.

Cell Reports, 2012 In meiosis, two specialized cell divisions allow the separation of paired chromosomes first, then of sister chromatids. Separase removes the cohesin complex holding sister chromatids together in a stepwise manner from chromosome arms in meiosis I, then ...

Developmental regulation of an organelle tether coordinates mitochondrial remodeling in meiosis. [PDF]
, 2018 Cellular differentiation involves remodeling cellular architecture to transform one cell type to another. By investigating mitochondrial dynamics during meiotic differentiation in budding yeast, we sought to understand how organelle morphogenesis is ...

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
