Figure 1. MeJA transport and metabolism in distal leaves. (A) The experimental set up includes Achyranthes plant and supply of the d₂MeJA solution at the 4th node (number 4), as shown in an inset. Details are mentioned in the text. (B) Quantitative profiling of emitted VOCs. Numbers correspond to: 1, methyl 2-(E)-hexenoate; 2, 3-(Z)-hexenyl acetate; 3, 2-(E)-hexenyl acetate; 4, (E)-β-ocimene; 5, linalool; 6, (E)-4,8-dimethyl-1,3,7-nonatriene; 7, (E)-β-caryophyllene; 8, (E)-α-bergamotene; 9, sesquisabinene; 10, (E)-β-farnesene; 11, α-humulene; 12, (E,E)-α-farnesene; and 13, β-bisabolene. (C) Absolute quantification of exogenous/endogenous JA and JA-Ile in the upper developed leaves (Fig. 1A; leaf 1 and 2). Data shown in (B) and (C) are derived from eight independent biological experiments and were used to calculate means and SE. Error bars represent standard errors.
