Project description:Nasonia vitripennis injects venom into its host organism Sarcophaga crassipalpis together with the eggs in order to make it suitable for the offspring to survive. The venom is known to suppress the hosts immune system, elevate the lipid levels, slow down development, et cetera.This microarray can uncover new transcriptomal effects on the host organism after natural envenomation that have not been discovered by bioassays. Since transcriptomal effects will vary during time, two different time points have been selected, 3 and 25 hours after parasitization.

Project description:The aim of this experiment is to assess the off-target effect of RNAi in Nasonia vitripennis at transcriptome level by comparing the effect of a non-specific RNAi against GFP together with water or not injected controls.
Project description:We quantified genome-wide total and allele-specific expression in two non-social parasitoids wasp species Nasonia vitripennis and Nasonia giraulti and their reciprocal F1 hybrids. No parent-of-origin effect in allelic expression was found for >8,000 informative genes, suggesting lack of genomic imprinting in adult Nasonia. Gene expression divergence between Nv and Ng could be attributed to both significant cis- and trans- regulatory changes during evolution.
Project description:However, that work lacked direct evidence of the effects of 5-aza-dC on DNA methylation, and indeed the effect of the chemical has since been questioned in Nasonia. Here, using whole-genome bisulphite sequencing of more than 4 million CpGs, across more than 11,000 genes, we demonstrate unequivocally that 5-aza-dC disrupts methylation on a large scale across the Nasonia vitripennis genome.
