Y chromosomes often degenerate via the accumulation of pseudogenes and transposable elements. By contrast, little is known about X-chromosome degeneration. Here we compare the pseudogenization process between genes on the neo-sex chromosomes in Drosophila miranda and their autosomal orthologues in closely related species. The pseudogenization rate on the neo-X is much lower than the rate on the neo-Y, but appears to be higher than the rate on the orthologous autosome in D. pseudoobscura. Genes… 
Evolutionary trajectories of three independent neo-sex chromosomes in Drosophila
The evolution of two additional neo-sex chromosomes in Drosophila share a common evolutionary trajectory after their emergence, which may be applicable to other sex chromosomes in a variety of organisms to avoid being an evolutionary dead-end.
Gene-by-Gene or Localized Dosage Compensation on the Neo-X Chromosome in Drosophila miranda
Molecular evolutionary analysis supports the idea that many individual neo-X-linked genes first acquired the potential for up-regulation, which then enabled the pseudogenization of neo-Y-linked homologs, without serious deleterious effects on male fitness.
An investigation of Y chromosome incorporations in 400 species of Drosophila and related genera
Y incorporation is an underappreciated mechanism affecting Y chromosome evolution; the results show that at least in Drosophila it plays a relevant role and highlight the need of similar studies in other groups.
Widespread gene duplication and adaptive evolution in the RNA interference pathways of the Drosophila obscura group
These results confirm that RNAi genes, including genes of the antiviral and piRNA pathways, have undergone multiple independent duplications and that their history has been particularly labile within the obscura group, however, they suggest that the selective pressures driving these changes have not been consistent, implying that more than one selective agent may be responsible.
Topologically associating domains and their role in the evolution of genome structure and function in Drosophila
It is shown that conservation of TADs is associated with gene expression stability across tissues, and evidence of natural selection operating on structural variants at the TAD boundaries, but with the nature of selection differing between the SV types is shown.
Sex Chromosome Evolution in Muscid Flies
Genomic and transcriptomic sequence data is used to identify young sex chromosomes in two closely related muscid species and provide evidence that the nascent sex chromosomes of horn fly and stable fly were derived independently from each other and from the youngSex chromosomes of the closely related house fly (Musca domestica).
An actin-related protein that is most highly expressed in Drosophila testes is critical for embryonic development
It is found that under heat stress Arp53D-knockout (KO) females lay embryos with reduced nuclear integrity and lower viability; these defects are further exacerbated in Arp 53D-KO embryos.


Tissue- and stage-dependent dosage compensation on the neo-X chromosome in Drosophila pseudoobscura.
It is found that gene functions also affected the levels of DC, and the results suggest that DC in Drosophila species operates in a tissue/stage-dependent manner.
Reduced adaptation of a non-recombining neo-Y chromosome
Sex chromosomes are generally believed to have descended from a pair of homologous autosomes. Suppression of recombination between the ancestral sex chromosomes led to the genetic degeneration of the
Genomic degradation of a young Y chromosome in Drosophila miranda
Patterns of genome evolution in D. miranda demonstrate that degeneration of a recently formed Y chromosome can proceed very rapidly, by both an accumulation of repetitive DNA and degenerating of protein-coding genes, support a random model of Y inactivation.
Sex-Specific Adaptation Drives Early Sex Chromosome Evolution in Drosophila
The sex chromosomes of Drosophila miranda are studied, showing that the response to sex-specific selection can shift at different stages of X differentiation, resulting in masculinization or demasculinization of the X-chromosomal gene content.
Reversal of an ancient sex chromosome to an autosome in Drosophila
The results reveal several puzzling aspects of Drosophila dot chromosome biology to be possible remnants of its former life as a sex chromosome, such as its minor feminizing role in sex determination or its targeting by a chromosome-specific regulatory mechanism.
Evolution of gene function on the X chromosome versus the autosomes.
A synopsis of the current understanding of the origin of sex chromosomes, theoretical context for differences in rates and patterns of molecular evolution on the X chromosome versus the autosomes, as well as a summary of empirical molecular evolutionary data from Drosophila and mammalian genomes are presented.
Comparative genome sequencing of Drosophila pseudoobscura: chromosomal, gene, and cis-element evolution.
A pattern of repeat-mediated chromosomal rearrangement, and high coadaptation of both male genes and cis-regulatory sequences emerges as important themes of genome divergence between these species of Drosophila.
Ancient Male Recombination Shaped Genetic Diversity of Neo-Y Chromosome in Drosophila albomicans.
This work elucidated the evolutionary scenario of the neo-Y chromosome of D. albomicans having high genetic diversity without assuming selective force, i.e., it originated from a single chromosomal fusion event, experienced meiotic recombination during the initial stage of evolution and diverged from neo-X chromosome by the suppression of recombination.
Fusions of Muller's Elements during Chromosome Evolution of Drosophila albomicans
Based on the hypothesized chromosome arm homologies between D. melanogaster and D. albomicans, the fusion events in lineages of Sophophora and Drosophila are discussed.
