Plant immunity hormones regulate the expression of AtPME17. AtPME17 expression analysed by quantitative reverse transcription PCR at 48 hr postinoculation in Botrytis cinerea‐ or mock‐inoculated leaves of 6‐week‐old Arabidopsis thaliana wild‐type (WT) plants and defence hormone mutants. 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). Asterisks indicate significant differences between mutants and WT according to Student's t test (***p < .0002; **p < .0003)
