Intra-specific regulatory variation in Drosophila pseudoobscura. [PDF]
PLoS ONE, 2013 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 ...

Age-dependent male mating investment in Drosophila pseudoobscura. [PDF]
PLoS ONE, 2014 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 ...

PseudoBase: a genomic visualization and exploration resource for the Drosophila pseudoobscura subgroup [PDF]
Fly, 2021 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]
G3 Genes|Genomes|Genetics, 2021 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.

No evidence for learned mating discrimination in male
BMC Evolutionary Biology, 2006 Background Since females often pay a higher cost for heterospecific matings, mate discrimination and species recognition are driven primarily by female choice.

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis [PDF]
FlyDrosophila 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 ...

Assessment of rival males through the use of multiple sensory cues in the fruitfly Drosophila pseudoobscura. [PDF]
PLoS ONE, 2015 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 ...

Divergence of X-linked trans regulatory proteins and the misexpression of gene targets in sterile Drosophila pseudoobscura hybrids [PDF]
BMC Genomics, 2022 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

Meiotic transmission of Drosophila pseudoobscura chromosomal arrangements. [PDF]
PLoS ONE, 2007 Drosophila pseudoobscura harbors a rich gene arrangement polymorphism on the third chromosome generated by a series of overlapping paracentric inversions.

Extensive exchange of transposable elements in the Drosophila pseudoobscura group [PDF]
Mobile DNA, 2018 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.
