Figure 1

Local but no systemic increase of jasmonates after wounding in Ipomoea batatas. (a–j) Jasmonate levels after mechanical wounding by MecW (a,c,e,g,i; n = 10–11) and insect feeding by S. littoralis (b,d,f,h,j; n = 7–12) measured in I. batatas TN57 after 0.5 h, 1 h and 3 h. Phytohormone levels were measured in locally wounded leaves (dark gray bars) and the adjacent unwounded systemic leaf (light gray bars). Leaves from undamaged plants served as controls (black bars). Statistically significant differences between each treatment group after treatment were analyzed for each time point separately using one–way ANOVA. Different letters indicate significant differences among groups for p < 0.05, determined by Tukey’s test. In (a–j), data are presented as mean ± SEM.
