Project description:We generated RNA-seq data of Drosophila simulans and Drosophila mauritiana developing male genitalia in order to identify expression level differences between these species. These species are closely related, yet have dramatic differences in their male genital morphologies. Three independent RNA-seq library replicates were generated for Dsim w501 and Dmau D1 developing male genitalia. Flies were reared under the above conditions, and white pre-pupae collected. Males were selected using gonad size and allowed to develop in a humid container at 25ºC until stages 2 and 4.5 (see staging guide in (Hagen et al., 2019); tartan underlies the evolution of Drosophila male genital morphology). Between these stages, the claspers develop from a ridge structure to a distinct appendage separate from the surrounding tissue, and the posterior lobe has begun to extend outwards from the lateral plate primordia (Hagen et al., 2019). The heads of pupae were impaled with a needle onto a charcoal agar plate and submerged in 1xPBS. Dissection scissors were used to remove the distal tip of the pupal case and the outer membrane, and pressure applied to the abdomen to allow the developing genitalia to be quickly expelled from the pupal case and dissected away from the abdomen. Note that the entire genital arch, including internal genital organs (but not including abdominal tissue), was isolated for RNA extraction. The genitalia from fifteen males from each stage were collected and placed directly into TRIzol. RNA was then extracted using standard procedures. Quality and quantity of RNA was verified using a Qubit, and samples were sent to the Centre for Genomic Research at the University of Liverpool where dual-indexed, strand-specific RNA-seq libraries were prepared using NEBNext polyA selection and Ultra Directional RNA preparation kits. Samples were then sequenced using Illumina HiSeq 4000 (paired-end, 2x150 bp sequencing). Dsim w501 and Dmau D1 reads were mapped against reannotated reference coding sequences (Torres-Oliva et al., 2016).

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 4 day old sterile male F1 hybrids of Drosophila simulans and its sibling species, D. mauritiana. We analyzed hybrids using custom cDNA arrays we developed from RT-PCRs of spermatogenesis-related transcripts from these species and another sibling species (D. sechellia). The results from a commercial genome-wide array for this species pair, from the custom chip and the genome-wide chip for the D. simulans-D. sechellia species pair, and from the larvae of these two species pairs using the custom chip, is presented separately.

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. mauritiana. We analyzed hybrids using custom cDNA arrays we developed from RT-PCRs of spermatogenesis-related transcripts from these species and another sibling species (D. sechellia). 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. sechellia species pair, and from the larvae of the D. simulans-D. sechellia species pair, are presented separately.
