Higher gene flow in sex-related chromosomes than in autosomes 2 during fungal divergence

open access: yes, 2020
International audienceNonrecombining sex chromosomes are widely found to be more differentiated than autosomes among closely related species, due to smaller effective population size and/or to a disproportionally large-X effect in reproductive isolation.

Integrating Genetics With Epidemiological Measurements Identifies Burden QTLs of Inflammatory Bowel Disease across 20 Countries

open access: yesAdvanced Science, EarlyView.
The burden quantitative trait locus (bQTL) analysis integrates epidemiological data from GBD study with genotype of 2 621 978 SNPs from 2414 individuals in 1000 Genomes Project across 20 countries. rs7633471 shows the strongest effect that each increase in centi‐allele frequency of the allele C associated with 10.00 decrease of age‐standardized ...

Neo-sex chromosomes of Ronderosia bergi: insight into the evolution of sex chromosomes in grasshoppers [PDF]

open access: yes, 2015
Sex chromosomes have evolved many times from morphologically identical autosome pairs, most often presenting several recombination suppression events, followed by accumulation of repetitive DNA sequences.

The wild grape genome sequence provides insights into the transition from dioecy to hermaphroditism during grape domestication

open access: yesGenome Biology, 2020
Background A key step in domestication of the grapevine was the transition from separate sexes (dioecy) in wild Vitis vinifera ssp. sylvestris (V. sylvestris) to hermaphroditism in cultivated Vitis vinifera ssp. sativa (V. vinifera).

TRAIP Mediates Alcohol‐Induced Liver Injury through Regulating β‐catenin Ubiquitin Degradation via Direct Interaction

open access: yesAdvanced Science, EarlyView.
This study reveals that NF‐κB1‐driven TRAIP upregulation in ALD correlates with disease severity. Mechanistically, TRAIP directly binds β‐catenin via its CC domain and promotes its K48‐linked ubiquitination and degradation, which is independent of the GSK3β/β‐TrCP pathway.

Molecular sexing and population genetic inference using a sex-linked microsatellite marker in the nine-spined stickleback (Pungitius pungitius)

open access: yesBMC Research Notes, 2011
Background Sex-specific DNA markers can serve as tools for molecular sex identification, as well as for population genetic inferences. We investigated the potential utility of a microsatellite marker located on sex chromosomes for molecular sexing of ...

Sex Steroids and Sex Chromosomes at Odds? [PDF]

open access: yesEndocrinology, 2005
Alfred Jost’s proposal in the 1940s (1) that testes are crucial for the development of the male phenotype, and that without them the body develops in a female direction, has been driving research in the field of sexual differentiation for more than half a century.

Reconstructing the Evolution of Vertebrate Sex Chromosomes

open access: yes, 2009
http://symposium.cshlp.org/content/74/345.full.pdf+htmlSex chromosomes and their evolution have captivated researchers since their discovery. For more than 100 years, the dominant model of sex chromosome evolution has held that differentiated sex ...
