Transcriptional analysis of Pieris rapae in response to P. rapae granulovirus

Pieris rapae granulovirus (PrGV) is an important pathogen that has been exploited as a microbial insecticide to control agriculture pests. They can specifically infect cabbage butterfly (Pieris rapae), causing a series of pathological symptoms. In this infected P. rapae at 6 h and 72 h. As a result, a series of host genes were significantly modulated following PrGV infection, including those correlated with exoskeleton, ribosome, heat shock protein (HSP), proteasome, oxidation-reduction and apoptosis. Taken together, our study unveiled the P. rapae response to PrGV at different time point and provided a potential strategy for pest management. [Display omitted] •The transcriptomes of Pieris rapae uninfected/infected with PrGV was unveiled.•The majority of PrGV ORFs were assembled in the same unigene.•Genes related with proteasome, oxidation-reduction, apoptosis et al. were modulated.
