The KEGG pathway classifications of the grain aphid specific unigenes. Among 4,857 unigenes, 607 had been annotated with KEGG terms, and the classification of these unigenes showed that many of them were categorized into the groups of metabolic pathways (34.1%), biosynthesis of secondary metabolites (13.4%), protein processing in endoplasmic reticulum (4.3%), purine metabolism (4.0%), oxidative phosphorylation, (3.5%), starch and sucrose metabolism (3.1%), aminobenoate degradation (2.8%), polycyclic aromatic hydrocarbon degradation (2.3%), bisphenol degradation (2.0%), and others.
