Is partial desynapsis in cauliflower (Brassica oleracea L. var. botrytis) pollen mother cells linked to aneuploidy in the crop?
Trisomic cauliflower plants ( Brassica oleracea L. var. botrytis ) display abnormal curd phenotypes that seriously decrease commercial value of the...

Fungal vaccines and adjuvants: a tool to reveal the interaction between host and fungi
Fungal infections are incurring high risks in a range from superficial mucosal discomforts (such as oropharyngeal candidiasis and vulvovaginal...

Cytogenetic analysis of meiotic behaviour and stability in a trigeneric hybrid (triticale x trigopiro)
Trigeneric hybrids in Triticeae may help to establish evolutionary relationships among different genomes present in the same cellular genetic...

A cyclical switch of gametogenic pathways in hybrids depends on the ploidy level
The cellular and molecular mechanisms governing sexual reproduction are conserved across eukaryotes. Nevertheless, hybridization can disrupt these...

The RING Domain of Rice HEI10 is Essential for Male, But Not Female Fertility
HEI10 is a conserved E3 ubiquitin ligase involved in crossover formation during meiosis, and is thus essential for both male and female gamete...

Meiosis and male fertility in F1 interspecific hybrids (Passiflora vitifolia vs. Passiflora hatschbachii)
Interspecific hybrids can be studied using methodologies in which the male gamete with high reproduction potential, viability, and fertility is...

From Olive Oil Emulsions to COVID-19 Vaccines: Liposomes Came First
It has been a long journey from Pliny the Elder (23–79 AD) to the FDA approval of the first injectable nanomedicine in 1997. A journey powered by... -
Antifungal Vaccines: Current Status and Future Directions
Fungal infections include a wide range of opportunistic and invasive diseases; these had a rebound in the last two decades due to the increase in the... -
ZmSPO11-2 is critical for meiotic recombination in maize
Most plant species have three or more SPO11/TOPOVIA homologs and two TOPOVIB homologs, which associate to trigger meiotic double-strand break (DSB)...

Influence of Forced Running Loads on the Content of Na+/K+-ATPase Isoforms and Monovalent Cations in Skeletal Muscles of Mice with a Model of Type II Diabetes Mellitus
AbstractThe effect of forced running for 1 hour daily for 4 weeks on the content of Na + /K + -ATPase isoforms and monovalent cations in the skeletal...

Germline-restricted chromosome shows remarkable variation in size among closely related passerine species
Passerine birds have a supernumerary chromosome in their germ cells called the germline-restricted chromosome (GRC). The GRC was first discovered...

Prdm9 deficiency of rat oocytes causes synapsis among non-homologous chromosomes and aneuploidy
Aneuploidy (abnormal chromosome number) accompanies reduced ovarian function in humans and mice, but the reasons behind this concomitance remain...

Fungal Extracellular Vesicles as a Potential Strategy for Vaccine Development
Extracellular vesicles (EVs) are released by virtually all live cells. In fungal organisms, the EVs traverse the cell wall and reach the... -
A cytological revisit on parthenogenetic Artemia and the deficiency of a meiosis-specific recombinase DMC1 in the possible transition from bisexuality to parthenogenesis
Although parthenogenesis is widespread in nature and known to have close relationships with bisexuality, the transitional mechanism is poorly...

Copy-number variation introduced by long transgenes compromises mouse male fertility independently of pachytene checkpoints
Long transgenes are often used in mammalian genetics, e.g., to rescue mutations in large genes. In the course of experiments addressing the genetic...

The meiotic topoisomerase VI B subunit (MTOPVIB) is essential for meiotic DNA double-strand break formation in barley (Hordeum vulgare L.)
Key messageIn barley ( Hordeum vulgare ), MTOPVIB is critical for meiotic DSB and accompanied SC and CO formation while dispensable for meiotic...

Meiosis and gametogenesis in hybrid, polyploid, and clonal fishes: case studies in the dojo loach Misgurnus anguillicaudatus
Hybrid, polyploid, and clonal fishes are found naturally in wild populations, but they can also be induced artificially by cross-breeding and...

A practical reference for studying meiosis in the model ciliate Tetrahymena thermophila
Meiosis is a critical cell division program that produces haploid gametes for sexual reproduction. Abnormalities in meiosis are often causes of...

Characteristics of δ-Aminolevulinic Acid Dehydratase of the Cold-Water Sponge Halisarca dujardinii
Abstractδ-Aminolevulinic acid dehydratase (ALAD) is a key enzyme of the cytoplasmic heme biosynthesis pathway. The primary structure of the ALAD ...
