Somatic genome‐doubling is the most parsimonious route to allopolyploidy

New Phytologist, Volume 250, Issue 5, Page 2845-2851, June 2026.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]

, 2004
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, Volume 13, Issue 22, 17 April 2026.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

BOLL‐Containing Aggregates Mediate the Translational Regulation During Human Oogenesis

Cell Proliferation, Volume 59, Issue 4, April 2026.
This work elucidates that BOLL‐containing aggregate‐mediated translational control is essential for human oogenesis. These aggregates recruit PABPC1 and FXR1 to activate the translation of U‐rich mRNAs encoding cell cycle proteins, thereby ensuring successful meiotic progression.

Review of expansion microscopy combined with advanced imaging modalities

Journal of Microscopy, Volume 301, Issue 3, Page 335-354, March 2026.
Abstract Expansion microscopy (ExM) is a powerful high‐resolution imaging technique that enhances the spatial resolution of conventional light microscopy by physically enlarging biological specimens by embedding and cross‐linking them in a swellable polymer network.

Mixing and Matching Chromosomes during Female Meiosis

Cells, 2020
Meiosis is a key event in the manufacturing of an oocyte. During this process, the oocyte creates a set of unique chromosomes by recombining paternal and maternal copies of homologous chromosomes, and by eliminating one set of chromosomes to become ...

Homolog pairing during meiosis : dyneins on the move [PDF]

, 2010
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

Genomic introgressions from wild relatives in the wheat genome alter meiotic dynamics in inter‐varietal hybrids

The Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY The use of wild relatives to introduce original diversity in the genome of bread wheat (Triticum aestivum L.) is an interesting approach to face the challenges of sustainable agriculture and the impact of climate change on wheat production. However, the influence of these wild‐species introgressions on meiosis in inter‐varietal wheat hybrids ...

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]

, 2011
During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, Volume 13, Issue 9, 13 February 2026.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...
