A, [11C]Gln metabolism, represented as the ratio of [11C]Glu to [11C]Gln, was plotted against tracer incubation for upper root tissues and root tips as a function of root herbivore treatment. Two key observations include (1) Gln metabolism is higher in upper root tissues than in tips, and (2) root herbivore treatment increases Gln metabolism across all spatial zones of the root. B, [11C]Gln metabolism, represented as the ratio of [11C]Glu to [11C]Gln was plotted against [11C]IAN metabolism, represented as the ratio of [11C]IAA to [11C]IAN, as a function of root herbivore treatment. Regression analysis reveals a strong correlation between the two biochemical processes as well as a significant positive herbivore treatment effect.
