qRT-PCR analysis of pathogen-related gene expression (MAPK cascade components; ET-, camalexin- and callose-related genes). Adult 4-week-old plants were sprayed with Pto DC3000 or water as a mock control and harvested at 0 h (white bars), 4 h (black bars), and 48 h (gray bars) post-infection. The relative gene expression was normalized to the reference gene, ACTIN2. Results are mean of three biological and two technical replicates for each experiment. Error bars indicate SE. Values on the Y-axis are given on a log2 scale.
