Attenuation of flg22- and chitin-induced expression of PTI marker genes in AtERF15-Ri plants. (A) Expression of flg22-induced expression of AtFRK1 and AtWRKY53. (B) Expression of chitin-induced expression of AtFRK1 and AtWRKY53. Disks from leaves of four-week-old plants were treated with flg22 (100 nM), chitin (1 μM) or solutions as mock controls. Relative expression levels of the defense genes were expressed as folds of the AtActin gene. Data presented are the means ± SD from three independent experiments and different letters above the columns indicate significant differences at p < 0.05 level between the AtERF15-Ri and Col-0 plants at the same time points.
