Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

Biological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Genomic analysis of meiotic recombination in social insects [PDF]

, 2022
Meiotic recombination is a key event of sexual reproduction in higher eukaryotes that shuffles allele combinations and promotes accurate segregation of chromosomes. The rate of meiotic recombination varies within and across species.

ReCombine: a suite of programs for detection and analysis of meiotic recombination in whole-genome datasets. [PDF]

PLoS ONE, 2011
In meiosis, the exchange of DNA between chromosomes by homologous recombination is a critical step that ensures proper chromosome segregation and increases genetic diversity.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

An expanded inventory of conserved meiotic genes provides evidence for sex in Trichomonas vaginalis.

PLoS ONE, 2007
Meiosis is a defining feature of eukaryotes but its phylogenetic distribution has not been broadly determined, especially among eukaryotic microorganisms (i.e. protists)-which represent the majority of eukaryotic 'supergroups'.

Identification and quality characterization of a putative novel 17x + 8y high‐molecular‐weight glutenin subunit recombination in bread wheat

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND High‐molecular‐weight glutenin subunits (HMW‐GSs) are major determinants of dough rheological behavior and bread‐making quality in bread wheat (Triticum aestivum L.). Among wheat genomes, the Glu‐B1 locus exhibits the highest allelic diversity; however, recombination events between x‐ and y‐type HMW‐GS genes are considered extremely

On the origin of trisomy 21 Down syndrome [PDF]

, 2008
Background: Down syndrome, characterized by an extra chromosome 21 is the most common genetic cause for congenital malformations and learning disability.

FBXO47 is essential for preventing the synaptonemal complex from premature disassembly in mouse male meiosis

iScience, 2022
Summary: Meiotic prophase I is a prolonged G2 phase that ensures the completion of numerous meiosis-specific chromosome events. During meiotic prophase I, homologous chromosomes undergo synapsis to facilitate meiotic recombination yielding crossovers. It

CryoBN‐PAGE: A Rapid and Cost‐Effective Method for the Analysis of Yeast Respiratory Complexes and Their Dynamic Organization

Yeast, EarlyView.
We present cryoBN‐PAGE, a method that enables blue native polyacrylamide gel electrophoresis analysis of mitochondrial respiratory complexes and supercomplexes directly from whole yeast cells using cryogenic milling. This approach eliminates the need for mitochondrial isolation, reducing time and cost while preserving native protein complexes.

Initiation of Meiotic Recombination in Ustilago maydis [PDF]

Genetics, 2013
Abstract A central feature of meiosis is the pairing and recombination of homologous chromosomes. Ustilago maydis, a biotrophic fungus that parasitizes maize, has long been utilized as an experimental system for studying recombination, but it has not been clear when in the life cycle meiotic recombination initiates.
