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 ...

Efeitos de meios de cultura na formação de calos a partir de anteras de aspargo (Asparagus officinalis L.) Effects of the culture media on the calli formation from Asparagus officinalis L. anthers

Acta Botânica Brasílica, 1995
Técnicas auxiliares, como a cultura de anteras, possibilitam melhor eficiência na obtenção de novos genótipos de aspargo. Neste trabalho, foram utilizadas anteras contendo grãos de pólen, no estágio uninucleado, dos híbridos 56x22-8 e 47x22-8, em meio MS,

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Effect of genotypic background on haploid production through embryo rescue in wheat × maize crosses - Short Communication

Plant, Soil and Environment, 2005
Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3.

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Stable demographic ratios of haploid gametophyte to diploid sporophyte abundance in macroalgal populations.

PLoS ONE
Macroalgal populations often consist of free-living haploid (gametophyte) and diploid (sporophyte) stages. Various ecological studies have been conducted to examine the demographic diversity of haploid-diploid populations with regard to the dominant ...

Meiosis in haploid yeast [PDF]

Proceedings of the National Academy of Sciences, 1982
Haploid yeast cells normally contain either the MAT a or MAT α mating-type allele and cannot undergo meiosis and spore formation. If both mating-type alleles are present as a consequence of chromosome III disomy ( MAT
