(a) Relative arabinofuranosidase (ABF) activity was quantified in FOR-infected wild type (Col-0), aos, coi1, ein2 and coi1 ein2 or mock-infected plants (n = 3) at 10 dpi. Error bars are the confidence intervals of the means (α = 0.05). (b) Foliar symptoms, such as stunting, epinasty and darkening (anthocyanin accumulation) of leaves, in FOR-infected wild type (bottom row) were suppressed in infected coi1 (top row). Notice wilted leaves (at arrows) on coi1 in watered soil.
