Gene sets affected by Hessian fly at early and late time points, and in resistant and susceptible plants. A: Gene sets in plants affected by Hessian fly at early time points (24 h or earlier) were different from those at late (72 h) time point. UI, DI, UC, and DC represent up-regulated in plants during incompatible interactions, down-regulated during incompatible interactions, up-regulated during compatible interactions, and down-regulated during compatible interactions. Commonly regulated transcripts were defined as those that were either up- or down-regulated at the two time points under comparison. Comparisons were made between time points 6 and 12 h (6/12), 6 and 24 h (6/24), 6 and 72 h (6/72), 12 and 72 h (12/72). B: Gene sets up-regulated in resistant plants were different from those up-regulated in susceptible plants. (a) Commonly up- (U) or down-regulated (D) in both resistant and susceptible plants at the same time points. (b) Commonly up- (U) or down-regulated (D) transcripts in resistant plants at an earlier time point and in susceptible plants at a later time point to examine potential delayed reaction in susceptible plants. C: Genes regulated in opposite directions in infested resistant and susceptible plants. (a) Percentages of affected transcripts that exhibited changes in abundance in opposite directions at the same time points. UI-DC – Percentages of up-regulated in resistant plants during incompatible interactions, which were down-regulated in susceptible plants during compatible interactions; DI-UC – Percentages of down-regulated transcripts in plants during incompatible interactions, which were up-regulated in plants during compatible interactions. (b) Percentages of affected transcripts with changes in opposite directions when data from infested resistant plants at an earlier time point compared with data from infested susceptible plants at a later time point.
