Infectivity of soil inoculated with Rhizoctonia solani Japanese isolates in young seedlings of Arabidopsis thaliana. PDA plugs prepared from R. solani grown in medium were inoculated to soil and incubated for 6 days. Then, 2-week-old Arabidopsis seedlings grown on MS agar plate medium were transplanted. Photographs were taken at 0, 7, and 14 days post-inoculation (dpi). Plain PDA plugs without fungus were used in the control treatment. The assays were performed three times with three biological replicates.
