Expression analysis of marker genes in response to elicitors. Arabidopsis seedlings were treated at the indicated time (h) with water (H2O), OGs, purified oligodecagalacturonic acid (DP10), flg22, trigalacturonic acid (DP3), or β-glucan (GLU). Expression of the indicated genes was analyzed by semiquantitative RT-PCR, using the UBQ5 gene as internal standard. This experiment was repeated twice with similar results.
