(Submitter supplied) The Dox meiotic drive system distorts the sex-ratio in Drosophila simulans. Here, the authors reconstruct the step-wise emergence, and recent amplification of Dox superfamily genes in parallel with the emergence of autosomal hairpin RNA-class siRNA loci that target subsets of these putative drivers

(Submitter supplied) During embryogenesis in animals, initial developmental processes are driven entirely by maternally provided gene products that are deposited into the oocyte. The zygotic genome is transcriptionally activated later, when developmental control is handed off from maternal gene products to the zygote during the maternal to zygotic transition (MZT). The MZT is highly regulated and conserved across all animals, and while some details change across model systems where it has been studied, most are too evolutionarily diverged to make comparisons as to how this process evolves. more...

(Submitter supplied) The piRNA pathway is an adaptive mechanism for maintaining the stability of the genome by repression selfish genomic elements such as transposons. As a host defense mechanism the piRNA pathway is rapidly evolving with different sets of piRNA silencing different targets in closely-related species. In male germline of D.melanogaster, repression of Stellate genes by piRNA generated from Supressor of Stellate, Su(Ste), locus is required for male fertility, but both Su(Ste) piRNA and their targets are absent in other Drosophila species. more...

(Submitter supplied) The earliest stage of animal development is controlled by maternally deposited mRNA transcripts and proteins. Once the zygote is able to transcribe its own genome, maternal transcripts are degraded, in a tightly regulated process known as the maternal to zygotic transition (MZT). While this process has been well-studied within model species, we have little knowledge of how the pools of maternal and zygotic transcripts evolve. more...

(Submitter supplied) Background: RNA-seq based on short reads generated by next generation sequencing technologies has become the main approach to study differential gene expression. Until now the main applications of this technique have been to study the variation of gene expression in a whole organism, tissue or cell type under different conditions or at different developmental stages. However, RNA-seq also has a great potential to be used in evolutionary studies to investigate gene expression divergence in closely related species. more...

(Submitter supplied) Co-expression of genes that physically cluster together is a common characteristic of eukaryotic transcriptomes. Identifying these groups of co-expressed genes is important to the functional annotation of genomes and understanding the evolutionary fates of the clustered genes. We used microarrays to measure gene expression in seven closely related Drosophila species, to identify domains clusters within a species of Drosophila (D. 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) 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. more...
