Drosophila Male Meiosis

, 2017
In Drosophila males, there is no synaptonemal complex and recombination does not occur. Thus, Drosophila male meiosis is a good model system for the analysis of achiasmate chromosome segregation. In addition, due to their large size, the meiotic spindles of Drosophila males are an excellent system for mutational dissection of the mechanisms of spindle ...

The histone modification reader ZCWPW1 is required for meiosis prophase I in male but not in female mice

Science Advances, 2019
The histone modification reader ZCWPW1 guides male meiosis prophase I. Meiosis is a specialized type of cell division that creates haploid germ cells and ensures their genetic diversity through homologous recombination.

HIM-10 is required for kinetochore structure and function on Caenorhabditis elegans holocentric chromosomes. [PDF]

, 2001
Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

Spo13 prevents premature cohesin cleavage during meiosis [version 1; peer review: 2 approved, 1 approved with reservations]

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

The Arabidopsis Cdk1/Cdk2 homolog CDKA;1 controls chromosome axis assembly during plant meiosis

EMBO Journal, 2019
Meiosis is key to sexual reproduction and genetic diversity. Here, we show that the Arabidopsis cyclin‐dependent kinase Cdk1/Cdk2 homolog CDKA;1 is an important regulator of meiosis needed for several aspects of meiosis such as chromosome synapsis.

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.

Distinct and Overlapping Requirements for Cyclins A, B, and B3 in Drosophila Female Meiosis

G3: Genes, Genomes, Genetics, 2016
Meiosis, like mitosis, depends on the activity of the cyclin dependent kinase Cdk1 and its cyclin partners. Here, we examine the specific requirements for the three mitotic cyclins, A, B, and B3 in meiosis of Drosophila melanogaster.

Spatial single-cell sequencing of meiosis I arrested oocytes indicates acquisition of maternal transcripts from the soma

Cell Reports, 2023
Summary: Maternal RNAs are stored from minutes to decades in oocytes throughout meiosis I arrest in a transcriptionally quiescent state. Recent reports, however, propose a role for nascent transcription in arrested oocytes.

Cyclin B3 is required for metaphase to anaphase transition in oocyte meiosis I

Journal of Cell Biology, 2019
Meiosis with a single round of DNA replication and two successive rounds of chromosome segregation requires specific cyclins associated with cyclin-dependent kinases (CDKs) to ensure its fidelity.

Principles of meiotic chromosome assembly revealed in S. cerevisiae [PDF]

, 2019
During meiotic prophase, chromosomes organise into a series of chromatin loops emanating from a proteinaceous axis, but the mechanisms of assembly remain unclear.
