Cytomixis doesn’t induce obvious changes in chromatin modifications and programmed cell death in tobacco male meiocytes

open access: yesFrontiers in Plant Science, 2015
Cytomixis is a poorly studied process of nuclear migration between plant cells. It is so far unknown what drives cytomixis and what is the functional state of the chromatin migrating between cells.

RECQ4 restricts non‐interfering crossover formation to fine‐tune meiotic recombination rates in rice

open access: yesPlant Biotechnology Journal, Volume 23, Issue 9, Page 3760-3769, September 2025.
Summary Crop breeding fundamentally depends on meiotic crossovers (COs) to reshuffle genetic material and integrate favourable alleles into elite cultivars. Recombination frequency is of paramount importance in this process. Higher recombination rates enhance the probability of breaking linkage drag and generating novel allelic combinations.

Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of Robertsonian heterozygotes of Mus domesticus

open access: yesBiological Research, 2017
Background The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements.

Analysis of the synaptonemal complex of the nine-banded armadillo, Dasypus novemcinctus

open access: yesGenetics and Molecular Biology, 2000
The synaptonemal complex (SC) of three specimens of the nine-banded armadillo (Dasypus novemcinctus) was analyzed. Thirty-two bivalents (2n = 64) were observed, 31 of them being autosomes and one an XY sexual bivalent.

The conserved ATPase PCH-2 controls the number and distribution of crossovers by antagonizing their formation in Caenorhabditis elegans

open access: yeseLife
Meiotic crossover recombination is essential for both accurate chromosome segregation and the generation of new haplotypes for natural selection to act upon. This requirement is known as crossover assurance and is one example of crossover control.
