New method for visualization of C-heterochromatin in synaptonemal complex spreads
Comparative Cytogenetics, 2013 DAPI staining of the metaphase chromosomes pretreated with barium hydroxide generates a C-like banding pattern. In this work a protocol for visualizing similar pattern at the synaptonemal complex (SC) spreads after immunostaining is suggested.

Meiotic double strand breaks repair in sexually reproducing eukaryotes: We are not all equal. [PDF]
, 2012 The defining event of meiosis is prophase-I, during which the maternal and paternal chromosome find each other in the nucleus, pair, and align in a process called “synapses of the homologues”. Their faithful segregation during the first meiotic division (

Manipulating Unisexual–Sexual Reproduction Transition to Engineer Genome‐Reconstructed Polyploids
Advanced Science, Volume 12, Issue 33, September 4, 2025.This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Frontiers 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
Plant 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.

Biological 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.

Sequential Loading of Cohesin Subunits during the First Meiotic Prophase of Grasshoppers [PDF]
, 2007 A previous version of this article appeared as an Early Online Release on January 2, 2007 (doi:10.1371/journal.pgen.0030028.eor).The cohesin complexes play a key role in chromosome segregation during both mitosis and meiosis.

bioRxiv, 2017 During meiotic prophase, a structure called the synaptonemal complex (SC) assembles at the interface between aligned pairs of homologous chromosomes, and crossover recombination events occur between their DNA molecules.

Telomeres cluster de novo before the initiation of synapsis: a three-dimensional spatial analysis of telomere positions before and during meiotic prophase. [PDF]
, 1997 We have analyzed the progressive changes in the spatial distribution of telomeres during meiosis using three-dimensional, high resolution fluorescence microscopy.

Cell, 2017 Meiotic double-strand breaks (DSBs) are generated and repaired in a highly regulated manner to ensure formation of crossovers (COs) while also enabling efficient non-CO repair to restore genome integrity. Here we use Structured-Illumination Microscopy to
