(Submitter supplied) Species-specific regulation of gene expression contributes to the development and maintenance of reproductive isolation and to species differences in ecologically important traits. A better understanding of the evolutionary forces which shape regulatory variation and divergence can be developed by comparing expression differences among species and interspecific hybrids. Once expression differences are identified, the underlying genetics of regulatory variation or divergence can be explored. more...

(Submitter supplied) Species often produce sterile hybrids early in their evolutionary divergence, and some evidence suggests that hybrid sterility may be associated with deviations or disruptions in gene expression. In support of this idea, many studies have shown that a high proportion of male-biased genes are underexpressed compared to non-sex-biased genes in sterile F1 male hybrids of Drosophila species. In this study, we examined and compared patterns of misexpression in 4 day old sterile male F1 hybrids of Drosophila simulans and its sibling species, D. more...

(Submitter supplied) In order to test the hypothesis that adult hybrid misexpression results from the cascading effect of earlier-expressed developmentally important improperly regulated genes, as well as address whether Von Baer’s 3rd law (suggesting that earlier stages of development should be more similar between species than later stages) holds at the level of gene expression, we conducted whole-transcriptome Drosophila melanogaster cDNA microarray-based expression profiling of males of D. more...

(Submitter supplied) Using RNA-seq technology, a comprehensive assessment of cis regulatory divergence in interspecific hybrid female heads was conducted and patterns of sequence evolution (Begun et al. 2007) within causal loci were examined. Genotype specific references were shown to virtually eliminate the map bias plaguing this technology. A novel Bayesian model, which uses allele representation in F1 hybrid DNA sequence reads as a prior, was used to estimate allele frequencies in RNA sequences.

A mixed mRNA- seq library was prepared from D. melanogaster and D. sechellia poly(A) + RNA (mixed before library preparation, "D_mel_+_D_sec). more...

Differences in gene activity between these lineages follow a phylogenetic pattern, and 27% of all of the genes in these genomes differ in their developmental gene expression between at least two strains or species. more...
