How to halve ploidy : lessons from budding yeast meiosis [PDF]

, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Generative Cell Division, but Not Early Nuclear Reorganization, Requires Transcriptional Reactivation During Pollen Tube Growth

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Bicellular pollen often enters a desiccated state wherein development is temporarily arrested, enabling long‐term survival while maintaining the capacity for rapid activation upon hydration. Although the generative cell in mature pollen of Lilium species is known to have completed DNA replication, its precise cell‐cycle status and the ...

A microscopic study of cohesin [PDF]

, 2017
Cohesin is a ring-shaped Smc (Structural Maintenance of Chromosomes) complex that mediates DNA-DNA interactions between chromosomes (sister chromatid cohesion) and within chromosomes (looping).

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, Volume 59, Issue 6, June 2026.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Homologous recombination, sister chromatid cohesion, and chromosome condensation in mammalian meiosis [PDF]

, 2002
In the life cycle of sexually reproducing eukaryotes, haploid and diploid generations of cells alternate. Two types of cell division occur in such a life cycle: mitosis and meiosis. They are compared in chapter 1 .

Mechanisms of cohesin protection and removal during meiosis in Saccharomyces cerevisiae [PDF]

, 2019
Meiosis is a specialised form of cell division which results in the formation of haploid cells from a diploid progenitor, and thus meiosis halves the chromosome content of the parental cell.

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, Volume 13, Issue 27, 13 May 2026.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Cohesin-dependent regulation of gene expression during differentiation is lost in cohesin-mutated myeloid malignancies. [PDF]

, 2019
Cohesin complex disruption alters gene expression, and cohesin mutations are common in myeloid neoplasia, suggesting a critical role in hematopoiesis.

Pds5 promotes cohesin acetylation and stable cohesin–chromosome interaction

, 2012
International audiencePds5 and Wpl1 act as anti-establishment factors preventing sister-chromatid cohesion until counteracted in S-phase by the cohesin acetyl-transferase Eso1.
