XA21-LRR1Ri rice plants are unresponsive to RaxX21-sY peptide treatment. Gene expression of PR10b (a), 10 g28299 (b), and 04 g10010 (c) 6 h after 500nM application of RaxX21, RaxX21-sY, or mock treatment in mature leaves of the four independent XA21-LRR1Ri rice lines. Bars depict the average and standard deviation of expression level normalized to Kitaake mock treatment of two technical replicates. Different letters indicate a significant difference in gene expression (P < 0.05, ANOVA, Tukey-HSD). Experiment was performed two times with similar results
