A simple model for the influence of meiotic conversion tracts on GC content. [PDF]

open access: yesPLoS ONE, 2011
A strong correlation between GC content and recombination rate is observed in many eukaryotes, which is thought to be due to conversion events linked to the repair of meiotic double-strand breaks. In several organisms, the length of conversion tracts has

Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n 26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy) [PDF]

open access: yes, 2018
The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of meiosis.

Unraveling the meiotic puzzle: chromosome count, meiotic behaviour, and reproductive challenges in Phlomis cashmeriana Royle ex Benth. from the Kashmir Himalaya

open access: yesFrontiers in Conservation Science
Meiotic stability is crucial for maintaining reproductive success and genetic diversity in plants, especially in montane regions like the Himalaya, where fluctuating environmental conditions can disrupt normal chromosome behavior.

Reproductive characteristics of citrus rootstocks grown under greenhouse and field environments [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2013
The aim of the present study was to evaluate the possible effect of environmental factors on meiosis, meiotic index, pollenviability and in vitro germination of pollen from stock plants of the rootstocks Trifoliate, ‘Swingle’, ‘Troyer’, ‘Fepagro C13 ...

Tubulins in C. elegans [PDF]

open access: yes, 2018
The C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules.

The Drosophila Citrate Lyase Is Required for Cell Division during Spermatogenesis [PDF]

open access: yes, 2020
The Drosophila melanogaster DmATPCL gene encodes for the human ATP Citrate Lyase (ACL) ortholog, a metabolic enzyme that from citrate generates glucose-derived Acetyl-CoA, which fuels central biochemical reactions such as the synthesis of fatty acids ...

MEIOTIC BEHAVIOR OF ASYMMETRIC DYADS IN THE MALE DROSOPHILA [PDF]

open access: yesGenetics, 1973
ABSTRACT Crossing over in the interstitial region of the heterozygous V4 translocation in Drosophila melanogaster generates asymmetric dyads each consisting of a shorter and a longer chromatid It was shown previously that in the female the shorter is recovered preferentially (ZIMMERING 1955); the present work suggests that the same ...

Phospho-Regulation of Meiotic Prophase

open access: yesFrontiers in Cell and Developmental Biology, 2021
Germ cells undergoing meiosis rely on an intricate network of surveillance mechanisms that govern the production of euploid gametes for successful sexual reproduction.

The meiosis-specific Cdc20 family-member Ama1 promotes binding of the Ssp2 activator to the Smk1 MAP kinase. [PDF]

open access: yes, 2018
Smk1 is a meiosis-specific MAP kinase (MAPK) in budding yeast that is required for spore formation. It is localized to prospore membranes (PSMs), the structures that engulf haploid cells during meiosis II (MII).
