Sex-chromosome evolution: recent progress and the influence of male and female heterogamety

H Ellegren - Nature Reviews Genetics, 2011 - nature.com
It is now clear that sex chromosomes differ from autosomes in many aspects of genome
biology, such as organization, gene content and gene expression. Moreover, sex linkage has
numerous evolutionary genetic implications. Here, I provide a coherent overview of sex- ...

MDC1 directs chromosome-wide silencing of the sex chromosomes in male germ cells

Y Ichijima, M Ichijima, Z Lou… - Genes & …, 2011 - genesdev.cshlp.org
Chromosome-wide inactivation is an epigenetic signature of sex chromosomes. The mechanism
by which the chromosome-wide domain is recognized and gene silencing is induced remains
unclear. Here we identify an essential mechanism underlying the recognition of the ...

[HTML] Sex Chromosome-Specific Regulation in the Drosophila Male Germline But Little Evidence for Chromosomal Dosage Compensation or Meiotic Inactivation

[HTML] from plos.orgCD Meiklejohn, EL Landeen, JM Cook, SB Kingan… - PLoS Biology, 2011 - dx.plos.org
The evolution of heteromorphic sex chromosomes (eg, XY in males or ZW in females) has repeatedly
elicited the evolution of two kinds of chromosome-specific regulation: dosage
compensation—the equalization of X chromosome gene expression in males and ...

… Chromosome Pair Undergoes Synaptic Adjustment and Crossover Redistribution During Caenorhabditis elegans Meiosis: Implications for Sex Chromosome …

JV Henzel, K Nabeshima, M Schvarzstein… - Genetics, 2011 - Genetics Soc America
Heteromorphic sex chromosomes, such as the X/Y pair in mammals, differ in size and DNA sequence
yet function as homologs during meiosis; this bivalent asymmetry presents special challenges
for meiotic completion. In Caenorhabditis elegans males carrying mnT12, an X;IV fusion ...
