Figure 4. Differential expression patterns of the M. destructor GSTs during compatible and incompatible interactions with wheat. Quantitative analysis was performed using RNA samples from larvae participating in compatible interactions (Biotype L Hessian flies on susceptible ‘Newton’ wheat) and from larvae participating in incompatible interactions (Biotype L Hessian flies on resistant ‘Iris’ wheat) 1 through 4 days (d) post hatch. Values represent the Log of the mean relative expression value (REV) plotted against each of the four time points examined for (A) MdesGST-1 (B) MdesGST-2 and (C) MdesGST-3. REVs for all genes were calculated relative to the expression of a M. destructor ubiquitin gene. The standard error in all panels is represented by the error bar for two biological replicates (two technical replicates within each).
