Project description:In order to characterize duplication polymorphisms in Drosophila simulans, we applied comparative genome hybridization (CGH) using tiling arrays originally designed to cover the full euchromatic genome of its sister species D. melanogaster. We only used the ~900,000 probes in the tiling arrays that had a perfect and unique match to the D. simulans genome (droSim1). We inferred copy number changes with a Hidden Markov Model (HMM) that returned the posterior probabilities for copy number by comparing DNA hybridization intensities between natural isolates. The probabilities of mutation were parsed to make duplication calls. The supplementary file linked to each Sample record contains for each probe, its location in the D. simulans genome and its posterior probability of being duplicated (output from the Hiddem Markov Model)

Project description:Y chromosome from different Drosophila simulans were introgressed into the same genetic background. Strains showing distinct sex-ratio distortion were clustered according to the ratio of males and females observed in the progeny. Strains showing disproportionally high number of female flies in the progeny were contrasted with strains displaying the proportion of male and females flies close to 1:1. In addition, interspecific Y chromosome from Drosophila sechellia (Ysec) was compared with D. simulans Y chromosomes. Total RNA was extracted from whole flies using TRIzol (Life Technologies). The synthesis of cDNA and its labeling with fluorescent dyes (Cy3 and Cy5) as well as hybridization reactions were carried out using 3DNA protocols and reagents (Genisphere). A minimum of 2 biological replicas was used, however this number varied according to the hybridization design (See 'Branco et. al, Natural variation of the Y chromosome suppresses sex ratio distortion and modulates testis-specific gene expression in Drosophila simulans' for details of the hybridization design). Microarrays were ~18,000-feature cDNA arrays spotted with D. melanogaster cDNA PCR products. We have recently annotated these probes using the D. simulans genome. Possible biases introduced by using a D. melanogaster platform for a D. simulans genome are minimized because the probed genomes are essentially identical except for the Y chromosomes. Slides were scanned using Axon 400B scanner (Axon Instruments) and GenePix Pro 6.0 software. Foreground fluorescence of dye intensities was normalized by the Loess method in Bioconductor / Limma.

Project description: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 F1 hybrid male third instar larvae of Drosophila simulans and its sibling species, D. sechellia. We analyzed hybrids using custom cDNA arrays we developed from RT-PCRs of spermatogenesis-related transcripts from these species and another sibling species (D. mauritiana). The results from a commercial genome-wide array and custom chip for adults of this species pair, from the custom chip and the genome-wide chip for adults of the D. simulans-D. mauritiana species pair, and from the larvae of the D. simulans-D. mauritiana species pair, are presented separately.
