Silencing of LRR1 in the XA21 genetic background enhances susceptibility to Xoo. a Relative expression level of LRR1 in four independent transgenic rice lines. Bars depict the average and standard deviation of LRR1 expression normalized to Kitaake of two technical replicates. Different letters indicate a significant difference in gene expression (P < 0.05, ANOVA, Tukey-HSD). This experiment was repeated three times with similar results. b Lesion length of T2 generation XA21-LRR1Ri plants 14 days after inoculation with PXO99. Bars indicate the average lesion length and standard deviation of ten to 15 combined plants that had one to six inoculated leaves each. Different letters indicate a significant difference in lesion length (P < 0.05, Kruskal-Wallis test, Dunn’s post-hoc test with Benjamini–Hochberg correction). Lesion length of individual T2 plants from this experiment are shown in Additional file 4: Figure S4. Experimental results were repeated three times, with similar results. c Two representative inoculated leaves from each line were photographed at the time of lesion scoring
