Biosynthesized AgNPs induce antioxidant activity in Nicotiana benthamiana. a–d Activities of catalase (a), polyphenol oxidase (b), superoxide dismutase (c), and peroxidase (d) were measured after biosynthesized AgNPs treatment (1.2 Î¼g/mL) for 3 times (once per day). e DAB staining was used to detect the production of H2O2 in N. benthamiana after biosynthesized AgNPs treatment (1.2 Î¼g/mL) for 3 times (once per day). Mock, negative control (treated with sterilized distilled water). The data are mean ± standard error (n = 3). Data analysis was performed using Student’s t test (∗0.01 < P < 0.05)
