Figure 4

HAE-induced TPI activity is species-specific and correlated with induced levels of JA and JA-Ile. A: TPI activity was measured 24 h after induction. Letters indicate statistical significance among different treatments (p < 0.05, post hoc Tukey honest significant test after ANOVA). B and C: the correlation between induced TPI activity and induced JA (B) and JA-Ile (C) accumulation within 2 h. The induced TPI activity, JA and JA-Ile accumulation were calculated as Euclidean distance between control samples (wounding + water) and each HAE treated samples. The linear regression was calculated and shown in the figure. Each colour refers to different treatments: black, wounding + C18:3-Glu; dark grey, wounding + OS _Ms ; light grey, wounding + OS _Sl . Each symbol refers to different species: Filled circle, N. obtusifolia; filled triangle, N. linearis; filled square, N. acuminata; plus, N. attenuata; square with cross inside, N. pauciflora; star, N. miersii.
