Induction of callose deposition in wheat leaves. (A) Percentage of fluorescent pixels of callose relative to the total number of plant material pixels in cultivar ‘Mercato’ at 14 days post inoculation. Callose deposition occurred only in leaves infiltrated with 0.01% chitosan, but not in buffer-infiltrated mock leaves. (B) Idem as (A) for cultivar ‘Avalon’. Shown are average values (n = 10; ±standard error).
