Fig. 4 in Metabolite profiles of brown planthopper-susceptible and resistant rice (Oryza sativa) varieties associated with infestation and mechanical stimuli

Fig. 4. Normalized intensity of significant metabolites affected by BPH infestation (n = 3/group) with different response patterns: (A). similar response in BPHsusceptible KD and BPH-resistant RH, (B). late induction in KD variety, (C). early induction in RH but late induction in KD, (D). induction in RH in both BPH and mechanical piercing by a needle common response in KD and RH, (E). higher level in KD than RH, and (F). higher level in RH than KD. Unpaired-t test was used to compare the control (black bar) and the BPH-treated (white bar) groups and to compare the control (black bar) and the mechanical-treated (grey bar) groups (*p- value<0.05, **p-value<0.01 and ***p-value<0.001) per time per genotype. HAT represents hour after treatment. Error bars represent one standard deviation of the mean value. Normalized intensity of each feature was relative to the intensity of a reference sample.
