DAPsequencing data in "A doublesex-dependent transcriptional control model for Nasonia parasitoid wasps' sex differentiation"

Project description:In insects, sexual differentiation is orchestrated by one transcription factor, Doublesex (DSX). DSX affects Drosophila melanogaster male and female transcriptome, yet how DSX regulates gene expression in other species is unknown. We investigated sex-biased gene expression during juvenile development in the parasitoid wasp Nasonia vitripennis, finding that more than three-quarters of its genes are sex-biased at a certain point in development. Moreover, we transiently knocked down dsx expression to infer its role in sex-specific transcriptome regulation, revealing thousands of affected genes in males and a more subtle effect in females. Finally, we performed an in vitro DNA-protein interaction assay to identify DSX binding sites and primary DSX target genes. By integrating these three datasets, we defined DSX's regulatory function for all genes in N. vitripennis, revealing that DSX acts mainly in males as both an activator and a repressor. This male-centric model for DSX-mediated regulation is likely to apply to many other insect species.

A transcriptomic atlas of the parasitoid wasp Nasonia vitripennis across ploidy, sex, and tissue [RNA-seq WOM]

Project description:The parasitoid wasp Nasonia vitripennis is a major insect model for morphology, behavior, and genetics. It has haplodiploid sex determination: unfertilized eggs develop into haploid males and fertilized eggs develop into diploid females. Additionally, polyploids (diploid males, triploid females) occur in Nasonia, representing gene expression mechanisms regulating sexual maintenance outside of standard haplodiploidy. Here, we generated a transcriptomic atlas for N. vitripennis across two tissues (head and abdomen) for typical haploid males and diploid females and polyploid diploid males and triploid females. These data are a resource for analyses on transcriptomic differences across sex, tissue type, ploidy, strain, and temporal change.

Transcriptomic analysis of a symbiotic poxvirus in parasitoid wasps and fly hosts

Project description:Parasitoid wasps of the species Diachasmimorpha longicaudata are associated with a heritable poxvirus, known as DlEPV, that is stored in the venom gland of adult female wasps and transferred to tephritid fly hosts of the wasps during oviposition. We conducted a RNA-seq differential expression analysis to gain insight on how DlEPV can replicate in both wasps and their fly hosts but only cause pathogenic effects during replication in flies. Our analysis revealed that 91.2% (176 of 193) of DlEPV genes showed significant differential expression during peak virus replication in wasp venom glands compared to parasitized flies. Over 80% of DlEPV replication genes were significantly upregulated in wasps, while 79% of DlEPV putative virulence genes were significantly upregulated in fly hosts. These data therefore support a dichotomy of viral function, where virus replication is promoted in wasp tissue and virulence in host tissue. Such a division of viral activity could represent an important adaptation to maintain a stable symbiosis between this virus and its associated parasitoid.

The transcriptomic basis of oviposition behaviour in the parasitoid wasp Nasonia vitripennis

Project description:For many behaviours studied at the phenotypic level, we have little or no idea of where to start searching for “candidate” genes: the transcriptome provides such a starting point. Here we consider transcriptomic changes associated with oviposition in the parasitoid wasp Nasonia vitripennis. Oviposition is a key behaviour, as females are faced with a variety of decisions that will impact offspring fitness. These include choosing between hosts of differing quality, as well as deciding on clutch size and offspring sex ratio. We compared the whole-body transcriptomes of resting or ovipositing female Nasonia using a “DEEP-Sage” gene expression approach on the Illumina sequencing platform.

Whole-body transcriptomics of Nasonia vitripennis females as they respond to sex allocation cues

Project description:Linking the evolution of the phenotype to the underlying genotype is a key aim of evolutionary genetics and is crucial to our understanding of how natural selection shapes a trait. Here we consider the genetic basis of sex allocation behaviour in the parasitoid wasp Nasonia vitripennis using a transcriptomics approach. Females allocate offspring sex in line with Local Mate Competition (LMC) theory. Female-biased sex ratios are produced when one or few females lay eggs on a patch. As the number of females contributing offspring to a patch increases, less female-biased sex ratios are favoured. We contrasted the transcriptomic responses of females as they oviposit under conditions known to influence sex allocation: foundress number (a social cue) and the state of the host (parasitised or not). We found, that when females encounter other females on a patch, or assess host quality with their ovipositors, the resulting changes in sex allocation is not associated with significant changes in whole-body gene expression. We also found that the gene expression changes produced by females, as they facultatively allocate sex in response to a host cue and a social cue, are very closely correlated. We expanded the list of candidate genes associated with oviposition behaviour in Nasonia, some of which may be involved in fundamental processes underlying the ability to facultatively allocate sex, including sperm storage and utilisation.
