The Rice AAA-ATPase OsFIGNL1 Is Essential for Male Meiosis [PDF]

open access: yesFrontiers in Plant Science, 2017
Meiosis is crucial in reproduction of plants and ensuring genetic diversity. Although several genes involved in homologous recombination and DNA repair have been reported, their functions in rice (Oryza sativa) male meiosis remain poorly understood. Here,

Transcriptomics of Meiosis in the Male Mouse [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2021
Molecular studies of meiosis in mammals have been long relegated due to some intrinsic obstacles, namely the impossibility to reproduce the process in vitro, and the difficulty to obtain highly pure isolated cells of the different meiotic stages.

True polyploid meiosis in the human male [PDF]

open access: yesGenetics and Molecular Biology, 2018
Polyploidy does not usually occur in germinal cells of mammals and other higher vertebrates. We describe a unique example of mosaic autotetraploidy in the meiosis of a human male. Although the original observations were made in the late 1960s, we did not

The Inactivation of Arabidopsis UBC22 Results in Abnormal Chromosome Segregation in Female Meiosis, but Not in Male Meiosis [PDF]

open access: yesPlants, 2021
Protein ubiquitination is important for the regulation of meiosis in eukaryotes, including plants. However, little is known about the involvement of E2 ubiquitin-conjugating enzymes in plant meiosis.

Tapetum-Dependent Male Meiosis Progression in Plants: Increasing Evidence Emerges [PDF]

open access: yesFrontiers in Plant Science, 2020
In higher plants, male meiosis is a key process during microsporogenesis and is crucial for male fertility and seed set. Meiosis involves a highly dynamic organization of chromosomes and cytoskeleton and specifically takes place within sexual cells ...

Cyclin B Export to the Cytoplasm via the Nup62 Subcomplex and Subsequent Rapid Nuclear Import Are Required for the Initiation of Drosophila Male Meiosis [PDF]

open access: yesCells, 2023
The cyclin-dependent kinase 1 (Cdk1)–cyclin B (CycB) complex plays critical roles in cell-cycle regulation. Before Drosophila male meiosis, CycB is exported from the nucleus to the cytoplasm via the nuclear porin 62kD (Nup62) subcomplex of the nuclear ...

Nuclear translocation of MTL5 from cytoplasm requires its direct interaction with LIN9 and is essential for male meiosis and fertility. [PDF]

open access: yesPLoS Genetics, 2021
Meiosis is essential for the generation of gametes and sexual reproduction, yet the factors and underlying mechanisms regulating meiotic progression remain largely unknown.

Exploring Reproductive Timing in Olive Tree: Male Meiosis and Anthesis Events [PDF]

open access: yesPlants
The timing of male meiosis plays a pivotal role in ensuring successful pollination and may represent a critical window during which environmental stressors can significantly impact reproductive outcomes.

METTL16 is Required for Meiotic Sex Chromosome Inactivation and DSB Formation and Recombination during Male Meiosis [PDF]

open access: yesAdvanced Science
Meiosis in males is a critical process that ensures complete spermatogenesis and genetic diversity. However, the key regulators involved in this process and the underlying molecular mechanisms remain unclear.

ATR is a multifunctional regulator of male mouse meiosis [PDF]

open access: yesNature Communications, 2018
ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a tissue-specific knockout approach, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and synapsis.
