Fig. 4: S. sclerotiorum grows in and enhances the resistance of barley and rice against blast fungi.

Hyphae of strain DT-8 in the roots of rice (a) and barley (b), located in the intercellular and intracellular spaces. hy indicates hyphae, arrows indicate hyphae in root cells. Images were visualized by SEM. c, d DT-8-treated rice and barley, respectively, showing strong resistance against the rice blast fungus, M. oryzae; representative images of barley and rice inoculated with M. oryzae in a chamber. Barley and rice seeds were treated with DT-8 or water (mock) before sowing; photographs were taken at 5 dpi for barley and 7 dpi for rice.
