Loss of flavonoids in tomato af and are mutants correlates with decreased terpenoid accumulation. A, Flavonoid-to-terpenoid correlation in the af mutant (gray circle) and CHI9 control (open circle). B, Flavonoid-to-terpenoid association in the are mutant (gray triangle) and VF36 parent (open triangle). C, Flavonoid-to-terpenoid correlation under various light conditions. Data were obtained for rutin (most abundant flavonoid in tVI-GTs) and β-phellandrene (most abundant terpenoid in tVI-GTs) from CHI4 (circle), CHI9 (triangle), and af (square) under three light conditions (100 μE m⁻² s⁻¹, green symbols; 200 μE m⁻² s⁻¹, blue symbols; 500 μE m⁻² s⁻¹, orange symbols). For all graphs, data points represent the average of concentration measurements from leaf dips, with bars corresponding to standard error (if invisible, error bars are smaller than symbol) (n = 5). Where appropriate, statistical significance of pairwise comparisons based on an unpaired Student’s t test is indicated by asterisks (*P ≤ 0.01; **P ≤ 0.001; ***P ≤ 0.001).
