Divergence of the transcriptional response to immune challenge in fat body and hemocytes.

Larvae were immune challenged by injecting them with mineral oil containing wasp homogenate while control larvae were not injected. The transcriptional response was then measured by RNA sequencing 24 hours post injection. (A) Volcano plots comparing the magnitude and statistical significance of changes in gene expression after immune challenge. Each point is a gene, and they are coloured above an FDR threshold of 5%. (B) The magnitude of the transcriptional response to immune challenge in D. simulans compared to D. sechellia. Each point is a gene.
