ABSTRACT We carried out transcriptional profiling analysis in 10-d-old Arabidopsis thaliana seedlings treated with oli-
gogalacturonides (OGs), oligosaccharides derived from the plant cell wall, or the bacterial flagellin peptide Flg22, general
elicitors of the basal defense response in plants. Although detected by different receptors, both OGs and Flg22 trigger
