    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky et al.
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

    The MAP kinase pathway coordinates crossover designation with disassembly of synaptonemal complex proteins during meiosis

    Saravanapriah Nadarajan et al.
    Coordination between crossover designation and synaptonemal complex disassembly is executed via a conserved MAP kinase pathway and is critical for accurate chromosome segregation during meiosis.

    Juxtaposition of heterozygous and homozygous regions causes reciprocal crossover remodelling via interference during Arabidopsis meiosis

    Piotr A Ziolkowski et al.
    Heterozygosity changes the balance between interfering and non-interfering crossovers during Arabidopsis meiosis.

    A compartmentalized signaling network mediates crossover control in meiosis

    Liangyu Zhang et al.
    A regulatory circuit that localizes to the synaptonemal complex, a liquid crystalline compartment between chromosomes, ensures crossing-over while limiting the number of crossovers between homologous chromosomes during meiosis.

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

    Matthew P Miller et al.
    Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

    Methylation of histone H3K23 blocks DNA damage in pericentric heterochromatin during meiosis

    Romeo Papazyan et al.
    A previously unappreciated histone methylation pathway helps limit DNA double-strand break formation and recombination in heterochromatin during meiosis.

    Successful transmission and transcriptional deployment of a human chromosome via mouse male meiosis

    Christina Ernst et al.
    Transmission of an entire human chromosome through the mouse male germline reveals an unexpectedly high tolerance of aneuploidy during male meiosis and results in accurate transcriptional deployment despite massive epigenetic remodeling during spermatogenesis.

    Live cell imaging of meiosis in Arabidopsis thaliana

    Maria A Prusicki et al.
    Live cell imaging and the in vivo dissection into distinct stages, called landmarks, represents a new methodology for analyzing meiosis in Arabidopsis and likely in other species as well.

    Gene regulation: A transcriptional switch controls meiosis

    A Elizabeth Hildreth, Karen M Arndt
    A key protein involved in the segregation of meiotic chromosomes is produced 'just in time' by the regulated expression of two mRNA isoforms.

    The asymmetry of female meiosis reduces the frequency of inheritance of unpaired chromosomes

    Daniel B Cortes et al.
    Female meiotic spindles correct trisomy by expelling extra chromosomes into the first polar body.
