Comparative transcriptomics of chemosensory tissues between Drosophila species

Project description:These data contain RNA-seq samples generated from the main chemosensory organs of closely related Drosophila species (D. melanogaster, D. sechellia, D. simulans, D. santomea, D. erecta, and D. suzukii) from larava (head) and adults (antenna, forelegs, proboscis with maxillary palps, ovipositors (female only) for both males and females. The purpose for generating these data was to carry out evolutionary analyses of gene expression differences between the six species.

Genome-wide binding patterns of group B Sox proteins in four Drosophila species

Project description:We used DamID-seq to analyze the genome-wide binding patterns of the group B Sox proteins Dichaete and SoxNeuro in four species of Drosophila: D. melanogaster, D. simulans, D. yakuba and D. pseudoobscura. Both binding site turnover between species and a comparison of the binding properties of the two partially-redundant transcription factors were analyzed. We found that, despite widespread turnover, genomic intervals that are commonly bound by both Dichaete and SoxNeuro are highly conserved in Drosophila. DamID for Dichaete (Dichaete-Dam) was performed in D. melanogaster, D. simulans, D. yakuba and D. pseudoobscura, while DamID for SoxNeuro (SoxN-Dam) was performed in D. melanogaster and D. simulans. The control experiment, Dam-only, was performed in all species. Three biological replicates were sequenced for each condition in each species.

Drosophila Divergence 20091001

Project description:D. yakuba, D. simulans, and D. sechellia gDNA competitively hybridized against D. melanogaster to evaluate aCGH as a means to identify diverged orthologs. 2 D. sechellia vs D. melanogaster hybs - with dye swap, 2 D. simulans vs D. melanogaster hybs with dye swap, and 8 D. yakuba vs D. melanogaster hybs with balanced dye swaps. D. yakuba vs. D. melanogaster were then analyzed in all 2,4,6,8 possible combinations that incorporated dye-swap to asses sources of variation.

Comparison of testes gene expression of D. melanogaster species and their hybrids

Project description:Males hybrids from the crosses between species of the D. simulans clade are steriles as the females are fertiles. Hybrid male sterility is due to severe defects in spermatogenesis and phenotypic differences are observed between the different hybrids involving D. simulans, D. sechellia and D. mauritiana. In this study we are comparing gene expression in the testes of hybrids involving the female D. simulans and the males D. melanogaster, D. mauritiana, or D. sechellia to the gene expression in species testes. Keywords: Comparative genomic hybridization 4 species (D. melanogaster, D. simulans, D. sechellia, D. mauritiana) and 3 different hybrids were used in this study. RNA extracted from whole D. melanogaster males was used as a reference. Hybridizations were perfomed using RNA extraxted from a pool of 200 testes from a sample with RNA extracted from whole D. melanogaster males. At least three independent replicates per hybridizations were performed
