Comparative analysis of different host adaptation in two rice planthopper species

In this work, we compared the gut transcriptome of two planthoppers that colonized on rice, colonized on wheat, and transferred from rice to wheat. We found that the majority of differentially expressed genes in SBPH were Type I responsive, which are plastic and evolved in the same direction. Genes associated with sugar transporters and heat shock proteins showed similar expression trends between BPH and SBPH. However, distinct gene expression variation were found after BPH and SBPH transferring from rice to wheat, with detoxifying-, ribosomal-, and amino acid metabolic-related genes reciprocally regulated.
