Intra-specific regulatory variation in Drosophila pseudoobscura. [PDF]
It is generally accepted that gene regulation serves an important role in determining the phenotype. To shed light on the evolutionary forces operating on gene regulation, previous studies mainly focused on the expression differences between species and ...

PseudoBase: a genomic visualization and exploration resource for the Drosophila pseudoobscura subgroup [PDF]
Drosophila pseudoobscura is a classic model system for the study of evolutionary genetics and genomics. Given this long-standing interest, many genome sequences have accumulated for D. pseudoobscura and closely related species D. persimilis, D.

The spontaneous mutation rate of Drosophila pseudoobscura [PDF]
Abstract The spontaneous mutation rate is a very variable trait that is subject to drift, selection and is sometimes highly plastic. Consequently, its variation between close species, or even between populations from the same species, can be very large.

Assessment of rival males through the use of multiple sensory cues in the fruitfly Drosophila pseudoobscura. [PDF]
Environments vary stochastically, and animals need to behave in ways that best fit the conditions in which they find themselves. The social environment is particularly variable, and responding appropriately to it can be vital for an animal's success ...

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis [PDF]
Drosophila pseudoobscura and D. persimilis are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic ...

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

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

Divergence of X-linked trans regulatory proteins and the misexpression of gene targets in sterile Drosophila pseudoobscura hybrids [PDF]
Background The genetic basis of hybrid incompatibilities is characterized by pervasive cases of gene interactions. Sex chromosomes play a major role in speciation and X-linked hybrid male sterility (HMS) genes have been identified. Interestingly, some of

Age-dependent male mating investment in Drosophila pseudoobscura. [PDF]
Male mating investment can strongly influence fitness gained from a mating. Yet, male mating investment often changes with age. Life history theory predicts that mating investment should increase with age, and males should become less discriminatory ...

Extensive exchange of transposable elements in the Drosophila pseudoobscura group [PDF]
Background As species diverge, so does their transposable element (TE) content. Within a genome, TE families may eventually become dormant due to host-silencing mechanisms, natural selection and the accumulation of inactive copies.
