W + OS-induced JA accumulation in local and systemic leaves. The leaves undergoing source-sink transition, designated as the leaves 0, were wounded with a pattern wheel and 20 μl of 1/5 diluted M. sexta OS were immediately applied to wounds (W + OS). Samples were harvested at indicated times, and their JA and JA-Ile contents were analyzed. a Numbering of the leaf positions in a bolting N. attenuata plant and the additive angular distances assuming 3/8 phyllotaxis proceeding from the leaf 0. b JA and JA-Ile JA levels in treated local leaves 0. c JA and JA-Ile accumulation in local leaves 0 and in younger systemic leaves at different times after W + OS treatment. d JA and JA-Ile levels in local and systemic leaves 90 min after W + OS treatment. Values are mean ± SE; N = 5; n.d. = not detectable.
