Accumulation of herbivore defense-related secondary metabolites in EV and NaGSNOR-VIGS plants. Leaves of EV and NaGSNOR-VIGS plants were wounded with a pattern wheel, and were thereafter applied with 20 μl of water (W+W) or 20 μl of M. sexta oral secretions (W+OS). The activity of NaTPI (A), contents of caffeoylputrescine (CP) (B), diterpene glycosides (DTGs) (C), and nicotine (D) (mean ±SE) were determined in EV and NaGSNOR-VIGS plants 3 d after treatments; non-treated plants served as controls (Cont). Star indicates significantly different levels between EV and NaGSNOR-VIGS plants (Student's t test; *P ≤0.05; n=5).
