Testes Proteases Expression and Hybrid Male Sterility Between Subspecies of Drosophila pseudoobscura [PDF]
G3: Genes, Genomes, Genetics, 2019 Hybrid male sterility (HMS) is a form of postmating postzygotic isolation among closely related species that can act as an effective barrier to gene flow.

Chemical signals and social structures strengthen sexual isolation in Drosophila pseudoobscura [PDF]
Communications BiologySpecies that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species ...

Opposite environmental and genetic influences on body size in North American Drosophila pseudoobscura [PDF]
BMC Evol Biol, 2015 BACKGROUND: Populations of a species often differ in key traits. However, it is rarely known whether these differences are associated with genetic variation and evolved differences between populations, or are instead simply a plastic response to ...

Evolution of sex‐biased genes in Drosophila species with neo‐sex chromosomes: Potential contribution to reducing the sexual conflict [PDF]
Ecology and Evolution, Volume 14, Issue 7, July 2024.In theory, having sex chromosomes is advantageous to reduce sexual conflict. Our analyses revealed that many genes have acquired the sex‐biased expression on the neo‐sex chromosomes particularly at the larval stage. Our study indicates that cryptic sexual conflict at the preadult stages cannot be ignored, and some of these conflicts may have been ...

Paralog‐Dependent Specialization of Paf1C Subunit, Ctr9, for Sex Chromosome Gene Regulation and Male Germline Differentiation in Drosophila [PDF]
Genes to Cells, Volume 30, Issue 5, September 2025.We show that Drosophila melanogaster genome maintains testis‐specific paralogs encoding components of the transcription regulator Paf1C. One of the paralog products, Ctr9t, forms a unique compartment within the spermatocyte nucleolus. Ctr9t acts as a suppressor of X chromosome genes and an activator of Y chromosome fertility genes, thereby ensuring ...

Mating system variation drives rapid evolution of the female transcriptome in Drosophila pseudoobscura [PDF]
Ecol Evol, 2014 Interactions between the sexes are believed to be a potent source of selection on sex-specific evolution. The way in which sexual interactions influence male investment is much studied, but effects on females are more poorly understood.

Development and evolution of Drosophila chromatin landscape in a 3D genome context [PDF]
Nature CommunicationsLittle is known about how the epigenomic states change during development and evolution in a 3D genome context. Here we use Drosophila pseudoobscura with complex turnover of sex chromosomes as a model to address this, by collecting massive epigenomic and
