Project description:Deep sequencing of total RNA extracted from the genital discs of males for each of the following strains : Drosophila sechellia, Drosophila mauritiana, hybrid introgression line 3Q1(A) and hybrid introgression line Q1(A)

Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.

Project description:Deep sequencing of total RNA extracted from the genital discs of males for each of the following strains : Drosophila sechellia, Drosophila mauritiana, hybrid introgression line 3Q1(A) and hybrid introgression line Q1(A) Analysis of poly(A)+ RNA for three independent biological replicates of sequencing libraries for each of the following strains: D. sechellia w, D. mauritiana P-insertion Q1, hybrid introgression line 3Q1(A), and hybrid introgression line Q1(A). Male genital discs were obtained as described above, and total RNA was extracted using RNAqueousM-CM-^BM-BM-.-Micro Kit (Ambion). Poly(A)+ transcripts were isolated subsequently using MicroPoly(A)PuristM-CM-"M-BM-^DM-BM-" Kit (Ambion). To facilitate normalization of reads across our samples, at this stage of library construction we spiked-in small amounts of exogenous RNA from ArrayControlM-CM-"M-BM-^DM-BM-" Kit (Ambion) into each sample of poly(A)+ RNA. Paired-end sequencing was carried out by loading the samples onto four lanes (three samples per lane) of a flow cell and run on an Illumina Genome Analyzer IIx sequencer using 72 cycles per end of each paired-end read. Biological replicates of each genotype were loaded onto separate lanes.

Project description:Postmating reproductive isolation is often manifested as hybrid male sterility, for which X-linked genes are over-represented. In contrast, X-linked gene are significantly under-represented among testis-expressing gene.This seeming contradiction may be germane to the X:autosome imbalance hypothesis on hybrid sterility ,in which the X-linked effect is mediated mainly through the misexpression of autosomal genes. We compared gene expression in fertile and sterile males in the hybrids between two Drosophila species. These hybrid males differ only in a small region of the X chromosome containing the OdsH locus of hybrid sterility. Of genes expressed in the testis, autosomal genes were indeed more likely to be misexpressed than X-linked genes under the steriizing action of OdsH. We compared gene expression between D. simulans males that carried either a fertile or sterile introgression (referred to as F or S males, respectively) from D. mauritiana. The introgressions span approximately 1/10 of the X chromosome, but the difference between the two introgressions is only about 3 Kb which contains exons 3 – 4 of OdsH. In short, F and S males have the same genetic background with respect to species origin, except the source of a portion of the OdsH gene. Three separate extractions and hybridizations were carried out for the RNA samples derived from testes and abdomens in each of two introgression lines.
