Fig. 6. Under field conditions, plants impaired in (a) JA synthesis (EV/irAOC) and (b) perception (EV/irCOI1) in roots are more attacked by Empoasca spp. and Tupiocoris notatus, respectively.
Mean ± SE levels of cumulative plant damage over 6 weeks after transplantation to the plot. Grafts of the scions and rootstocks of the same genotypes (EV/EV, irAOC/irAOC, and irCOI1/irCOI1) were used as controls. Bars sharing same letters do not significantly differ (One-way ANOVA followed by Fisher LSD test, n = 25).
