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

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 ...

Spermatogenesis: The Commitment to Meiosis.

open access: yesPhysiological Reviews, 2016
Mammalian spermatogenesis requires a stem cell pool, a period of amplification of cell numbers, the completion of reduction division to haploid cells (meiosis), and the morphological transformation of the haploid cells into spermatozoa (spermiogenesis ...

Recombination, Pairing, and Synapsis of Homologs during Meiosis.

open access: yesCold Spring Harbor Perspectives in Biology, 2015
Recombination is a prominent feature of meiosis in which it plays an important role in increasing genetic diversity during inheritance. Additionally, in most organisms, recombination also plays mechanical roles in chromosomal processes, most notably to ...

Sexual-lineage-specific DNA methylation regulates meiosis in Arabidopsis

open access: yesNature Genetics, 2018
DNA methylation regulates eukaryotic gene expression and is extensively reprogrammed during animal development. However, whether developmental methylation reprogramming during the sporophytic life cycle of flowering plants regulates genes is presently ...

FEARless in Meiosis [PDF]

open access: yesMolecular 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.

Defining the developmental program leading to meiosis in maize

open access: yesScience, 2018
Following meiosis in maize Plants do not set aside a germ-cell lineage from early development as animals do, but instead generate germ cells on demand.

Actin cytoskeleton dynamics in mammalian oocyte meiosis†

open access: yesBiology of Reproduction, 2018
During mitosis, cells undergo symmetrical cell division, while oocyte meiotic maturation undergoes two consecutive, asymmetric divisions that generate a totipotent haploid oocyte and two small polar bodies not involved in DNA replication.

Control of Meiosis by Respiration [PDF]

open access: yesCurrent Biology, 2008
A cell's decision to undergo meiosis is regulated by multiple signals. In budding yeast, these signals include mating-type status, nutrient starvation, and respiration; the need for respiration is often manifested as a requirement for a nonfermentable carbon source.

The cohesin complex in mammalian meiosis

open access: yesGenes to Cells, 2018
Cohesin is an evolutionary conserved multi‐protein complex that plays a pivotal role in chromosome dynamics. It plays a role both in sister chromatid cohesion and in establishing higher order chromosome architecture, in somatic and germ cells.

Focus on Meiosis [PDF]

open access: yesReproduction, 2005
The past five years have seen the dawn of an era of illumination in our understanding of how vertebrate meiosis is regulated. Much of the foundation for recent progress came from the enormous advances in elucidating the molecular regulation of mitotic cell division and yeast meiosis (reviewed in Uhlmann 2001, Petronczki et al.
