Disease symptoms development on wheat cultivars infected by Zymoseptoria tritici IPO323.

(a) Plant infected by distilled water (Mock plant). (b) Cultivar Shafir is resistant to IPO323 (incompatible interaction) and no STB symptoms were observed on the inoculated leaves at 21 days post-inoculations. (c) Cultivar Taichung 29 is susceptible to IPO323 (compatible interaction), and necrotic lesions covered by abundant asexual fruiting bodies (pycnidia) were found on the infected leaves at 21 days post-inoculations. The first leaves of the applied cultivars were inoculated with IPO323, and photographs were taken at 21 days post-inoculation.
