Relative expression of the ascorbate peroxidase (A), catalase (B) and superoxide dismutase (C) gene normalized with the least stable reference genes (tubulin and 7s-globulin) in kiwifruit leaves inoculated with low dose of Pseudomonas syringae pv. actinidiae inoculum (LDI), leaves inoculated with high dose of P. s. pv. actinidiae inoculum (HDI) compared to the mock-inoculated plants (C). Data are expressed as mean ± standard deviation.
