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.

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 ...

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.

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.

Parametric alignment of Drosophila genomes. [PDF]
PLoS Computational Biology, 2006 The classic algorithms of Needleman-Wunsch and Smith-Waterman find a maximum a posteriori probability alignment for a pair hidden Markov model (PHMM). To process large genomes that have undergone complex genome rearrangements, almost all existing whole ...

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 ...

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

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.
