Figure 9.

The level of transcript of genes involved in free radical processing (CAT—catalase, APX—ascorbate peroxidase, SOD—superoxide dismutase, and PPO—polyphenol oxidase) in wild-type potato plants treated with 0.1 mg/mL l-DOPA presented as relative quantification (RQ) in relation to the non-treated control (horizontal line at RQ = 1). The elongation factor gene was used as a reference gene. The results were obtained with the RT-qPCR method on the cDNA matrix as the mean values of three biological repeats ± standard deviation. Statistically significant changes (p < 0.05) are marked with asterisks.
