HAE induced phytohormone responses in the different Nicotiana species is both HAE- and species-specific. Each column indicates a different species. The top row represents induced JA responses, the middle row represents induced JA-isoleucine (JA-Ile) responses and the bottom row represents induced salicylic acid (SA) responses. Phytohormones were measured at 0 h, 0.5 h, 1 h and 2 h after HAE induction. Different line types represent different treatments. Solid purple colour indicates wounding (W) + water, light blue dotted line indicates W + S. littoralis OS (OS Sl ) induction; green dashed line indicates W + M. sexta OS (OS Ms ) induction, and vermillion dashed line indicates W + C18:3-Glu induction. Letters indicate the statistically significant differences (p < 0.05) at the peak JA, JA-Ile and SA concentrations for each species as determined by ANOVA or Kruskal-Wallis test depending on whether the data were normally distributed or not. The error bar indicates standard error.
