Resistance phenotypes of OsWRKY80-overexpressing and RNAi transgenic rice plants to Rhizoctonia solani. a Disease symptoms in wild-type (WT), OsWRKY80-overexpressing (lines OX3-3 and 5-2), and RNAi (lines 3-1 and 8-6) plants at 14 days after inoculation (DPI) with Rhizoctonia solani GD118. b Progression of sheath blight disease evaluated by quantitating R. solani genomic DNA using qPCR analysis. The amount of R. solani 28S rDNA was calculated relative to rice RUBQ1 (AF184279) DNA. c Disease severity was evaluated as disease index at 14 DPI. Data are represented as mean values ± standard error (SE) for three replicates according to Duncan’s multiple range test (** P < 0.01). 20 plants for each genotype were used for each repetition
