FIGURE 3.

Expression of defence genes PR1, PDF1.2, PAD3, and RetOX in pme17 mutants after Botrytis cinerea induction. The expression of the selected defence genes was analysed by quantitative reverse transcription PCR at 48 hr postinoculation in B. cinerea‐ or mock‐inoculated leaves of 6‐week‐old Arabidopsis in pme17 mutants and wild‐type plants (WT). The expression levels were normalized to UBQ5 expression. The relative expression is represented as the ratio between gene expression in the mutants and WT plants. The results represent means ± SD of three independent experiments (n = 3). Different letters indicate data sets significantly different according to analysis of variance followed by Tukey's test (p < .01)
