Evolutionary strata on the X chromosomes of the dioecious plant Silene latifolia: Evidence from new sex-linked genes [PDF]

open access: yes, 2007
Despite its recent evolutionary origin, the sex chromosome system of the plant Silene latifolia shows signs of progressive suppression of recombination having created evolutionary strata of different X-Y divergence on sex chromosomes. However, even after

Deficiency in the multicopy Sycp3-like X-linked genes Slx and Slxl1 causes major defects in spermatid differentiation. [PDF]

open access: yes, 2010
The human and mouse sex chromosomes are enriched in multicopy genes required for postmeiotic differentiation of round spermatids into sperm. The gene Sly is present in multiple copies on the mouse Y chromosome and encodes a protein that is required for ...

X chromosome inactivation during Drosophila spermatogenesis [PDF]

open access: yes, 2007
Genes with male- and testis-enriched expression are under-represented on the Drosophila melanogaster X chromosome. There is also an excess of retrotransposed genes, many of which are expressed in testis, that have “escaped” the X chromosome and moved to ...

Lack of global meiotic sex chromosome inactivation, and paucity of tissue-specific gene expression on the Drosophila X chromosome

open access: yesBMC Biology, 2011
Background Paucity of male-biased genes on the Drosophila X chromosome is a well-established phenomenon, thought to be specifically linked to the role of these genes in reproduction and/or their expression in the meiotic male germline.

MHC-linked and un-linked class I genes in the wallaby [PDF]

open access: yes, 2009
Background: MHC class I antigens are encoded by a rapidly evolving gene family comprising classical and non-classical genes that are found in all vertebrates and involved in diverse immune functions.

A genetic basis for a postmeiotic X versus Y chromosome intragenomic conflict in the mouse. [PDF]

open access: yes, 2012
Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation.

Intelligence Quotient Variability in Klinefelter Syndrome Is Associated With GTPBP6 Expression Under Regulation of X-Chromosome Inactivation Pattern

open access: yesFrontiers in Genetics, 2021
Klinefelter syndrome (KS) displays a broad dysmorphological, endocrinological, and neuropsychological clinical spectrum. We hypothesized that the neurocognitive dysfunction present in KS relies on an imbalance in X-chromosome gene expression. Thus, the X-

LOCALISATION OF THE X-LINKED HYPOPHOSPHATAEMIC RICKETS GENE [PDF]

open access: yesPediatric Research, 1986
Cloned human X chromosome fragments identifying DNA sequence polymorphisms have been used as genetic markers in linkage studfes to localise the abnormal gene that causes X-linked hypophospbataemic rickets. These linkage studies were performed in 11 families in which the disease had occured in 3 or more generations.

Androgen-induced rhox homeobox genes modulate the expression of AR-regulated genes [PDF]

open access: yes, 2010
Rhox5, the founding member of the reproductive homeobox on the X chromosome (Rhox) gene cluster, encodes a homeodomain-containing transcription factor that is selectively expressed in Sertoli cells, where it promotes the survival of male germ cells ...

Over-expression of XIST, the Master Gene for X Chromosome Inactivation, in Females With Major Affective Disorders

open access: yesEBioMedicine, 2015
Background: Psychiatric disorders are common mental disorders without a pathological biomarker. Classic genetic studies found that an extra X chromosome frequently causes psychiatric symptoms in patients with either Klinefelter syndrome (XXY) or Triple X
