Evolution of sex-biased genes in Drosophila species with neo-sex chromosomes: Potential contribution to reducing the sexual conflict. [PDF]

open access: yesEcol Evol
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]

open access: yesGenes Cells
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 ...

Phylogenomic Analysis Reveals Evolutionary Relationships of Tropical Drosophilidae: From <i>Drosophila</i> to <i>Scaptodrosophila</i>. [PDF]

open access: yesEcol Evol
The study expands genomic resources for Drosophila and Scaptodrosophila species by using mitochondrial genomes. Phylogenetic analyses revealed well‐supported evolutionary relationships, with Scaptodrosophila forming a distinct lineage and several Drosophila subgroups exhibiting monophyly, though discrepancies were found in the placement of the suzukii ...

Development and evolution of Drosophila chromatin landscape in a 3D genome context [PDF]

open access: yesNature Communications
Little 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

Inversions shape the divergence of Drosophila pseudoobscura and Drosophila persimilis on multiple timescales

open access: yesEvolution; international journal of organic evolution, 2021
By shaping meiotic recombination, chromosomal inversions can influence genetic exchange between hybridizing species. Despite the recognized importance of inversions in evolutionary processes such as divergence and speciation, teasing apart the effects of
