TABLE 1.

Activity profile of eight antioxidant enzymatic signature in the different plant tissues of A. nordmanniana seedlings from seeds inoculated with selected bacterial strains and non-inoculated seeds (Control −) grown under non-stressed greenhouse conditions.

In addition to numeric means data are represented as a heatmap based on a gradient red-white-blue color scale. Dark red color indicates highest, dark blue color lowest values for each enzyme. Data are presented as mean values [nkat g FW⁻¹] derived from three biological replicates, each including three technical replicates (n = 9). * Significantly different to control (P < 0.05), based on two-sided, unpaired Student’s t-test. Superoxide dismutase (SOD), Catalase (CAT), Peroxidase (POX), Ascorbate peroxidase (APX), Glutathione reductase (GR), Dehydroascorbate reductase (DHAR), Monodehydroascorbate reductase activity (MDHAR), Glutathione S-transferase (GST).
