NaBAK1-silenced plants have increased levels of basal and MeJA-induced TPI activity. Leaves from EV and NaBAK1-VIGS plants were left untreated (control) or wounded with a pattern wheel and 20 μl of M. sexta oral secretions (OS) were immediately applied to each leaf (W+OS). Samples were harvested 3 d after treatment. TPI activity (±SE) (A) was determined. Each EV and NaBAK1-VIGS plants was treated with 20 μl of lanolin paste or lanolin paste containing MeJA (7.5 μg μl⁻¹). After 3 d, samples were harvested, and TPI activity (±SE) (B) was analysed. Error bars represent standard errors; different letters indicate significant differences (two-way ANOVA, Fisher's PLSD test; P <0.05; n=5).
