Technical Abstract: Genome wide analysis of gene expression in wheat after Hessian fly (Mayetiola destructor) infestation revealed that different metabolic pathways were affected differentially between compatible and incompatible interactions. In compatible interactions, genes in the pathways to produce nutrients for the Hessian fly were significantly up-regulated, including key enzymes in the amino acid synthesis, glycolysis, and citric acid cycle, while pathways to synthesize defense molecules were generally suppressed. In incompatible interactions, pathways leading to cell wall strengthening and toxic molecule synthesis were strongly induced, while general metabolic pathways for energy and nutrients were either unchanged or suppressed. In association with these differential responses, different sets of transcription factors were also regulated differently between compatible and incompatible interactions. We are currently investigating key molecules leading to these differential responses through specific gene silencing.
