Project description:DNA methylation is an important chromatin modification that is necessary for the structural integrity and proper regulation of the genome for many species. Despite its conservation across the tree of life, little is known about its contribution to complex traits. Reports that differences in DNA methylation between castes in closely related Hymenopteran insects (ants, bees and wasps) contributes to social behaviors has generated hypotheses on the role of DNA methylation in governing social behavior. However, social behavior has evolved multiple times across insecta, and a common role of DNA methylation in social behavior remains outstanding. Using phylogenetic comparative methods we sought to better understand patterns of DNA methylation and social behavior across insects. DNA methylation can be found in social and solitary insects from all orders, except Diptera (flies), which suggests a shared loss of DNA methylation within this order. The lack of DNA methylation is reflected in the absence of the maintenance and de novo DNA methyltransferases (DNMT) 1 and 3, respectively. Interestingly, DNA methylation is found in species without DNMT3. DNA methylation and social behavior (social/solitary) or with division of labor (caste+/caste–) for 123 insect species analyzed from 11 orders are not evolutionary dependent, which is further supported by sequencing of DNA methylomes from 40 species.

Project description:We describe the first comprehensive venom profile of a solitary bee, the European carpenter bee Xylocopa violacea, by using a combined proteo-transcriptomic approach. Transcripts of the venom system are used as specific database to match peptide sequences from mass spectrometry analyses of venom from dissected venom glands and venom injected during a defensive sting. In our analyses, we only discuss the proteo-transcriptomically supported venom components and reveal a diverse venom profile with 43 different protein families of which 32 are identified in the injected venom.

Project description:Here we reveal evidence of a shared genetic toolkit across the full spectrum of social complexity found in Vespid wasps, from simple group living where castes remain plastic throughout life, to complex superorganismal societies comprised of mutually dependent insects with irreversible castes determined during development. We generated brain transcriptomic data for castes in nine representative species; using a machine learning approach we identified thousands of shared orthologs which consistently describe castes (queens and workers), from species with the simplest (Mischocyttarus paper wasps) to the most complex (e.g. Vespine wasps) levels of social organisation. The top 400 genes were enriched in synaptic transport genes, suggesting that these changes could affect brain neural function and connectivity. Fine-scale dissection of these patterns revealed that the molecular processes underpinning the simpler societies (which likely represent the origins of social living) are conserved throughout the major transition, but that additional processes may come into play in the more complex societies, especially at the point of no return where societies transition to be committed superorganisms. These analyses provide the first evidence of a conserved toolkit regulating social behaviour across the full spectrum of social complexity in any social insect. Importantly, they also provide evidence that there may be fundamental differences discriminating superorganismal societies from non-superorganismal societies. We suggest that the evolution of irreversible caste commitment (in superorganisms) is accompanied by a fundamental shift in the underlying regulatory molecular machinery; such shifts may also typify other major evolutionary transitions that are characterised by the emergence of a committed division of labour, such as the evolution of multicellularity.

Project description:Upon pathogenic infection, drosophila larval host mounts an immune response. Parasitic wasps inject venom that contain virulence factors during oviposition, which can elicit host immune response, and in some cases, suppress host immune responses altogether. Several microarray experiments have been performed on different classes of parasitic wasps. We wanted to compare how Ganaspis xanthopoda-infected hosts respond compared to other classes of parasitic wasps.

Project description:We evaluated the profile of miRNA and snoRNA expression in 7 solitary CRC and matched normal colorectal tissues using the Affymetrix GeneChip miRNA 1.0 array. We found that global dysregulated miRNAs and snoRNAs between cancer tissue and normal mucosa in solitary CRC. Our findings firstly implicates that dysregulation of snoRNAs and miRNA may play important role in the cancinogenesis and present therapeutic targets for solitary CRC.

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.

Project description:We studied behavioral, brain transcriptomic and epigenetic responses of honey bees to social challenge. Bees were exposed to two intruders at different intervals. The initial exposure caused two behavioral effects at the individual level: an increase in the intensity of aggression toward a second intruder at 30 and 60 minutes, and an increased probability of responding aggressively toward a second intruder that persisted for two hours. The shorter-lived response was associated with one pattern of gene expression in the mushroom bodies, highlighted by genes related to cytoskeleton remodeling. The longer-lived response was associated with a different pattern; highlighted by genes related to hormones, stress response and transcription factors. Histone profiling revealed few changes in chromatin accessibility in response to social challenge; most differentially expressed genes were “ready” to be activated. These results demonstrate how biological embedding of a social challenge involves changes in the neurogenomic state to influence future behavior.

Project description:Diachasmimorpha longicaudata parasitoid wasps carry a symbiotic poxvirus, known as DlEPV, within the female wasp venom gland. We sequenced RNA from venom gland tissue to identify DlEPV orthologs for 3 conserved poxvirus core genes. The DlEPV ORFs identified from this transcriptome were used to design primers for downstream RT-qPCR analysis and RNAi knockdown experiments.
