Infectivity of Rhizoctonia solani Japanese isolates in detached leaves of 4-week-old Arabidopsis thaliana. Leaves were inoculated with 6 mm mycelial PDA plugs and incubated in a humid condition at 23 °C for 5 days. Photographs were taken at 0, 3, and 5 days post-inoculation (dpi). Plain PDA plugs without fungus were used as a control. The assays were performed three times with three biological replicates. Bars, 1 cm.
