Abstract

In this study, effect of different concentrations of AgNO3 (4 hours after treatment) and CuSO4 (16 hours after treatment) elicitors were investigated on gene expression of FNS I and antioxidant system in 21-dayCuminum cyminum seedlings. Semi-quantitative study of FNS I gene expression showed a significant increase at 25 and 50 mM Ag+ concentrations rather than the control which had a decrease by the addition of the elicitor to the concentration of up to 100 mM. On the other hand, by the increase in this elicitor concentration, total FLAVONOID and ANTHOCYANIN contents and activity of some ANTIOXIDANT ENZYMES as well as total protein content significantly increased compared with the control group. The gene expression was significantly elevated in the treated seedlings by Cu elicitor at 4 and 8 μM treatments while its expression was completely inhibited at 16 μM concentration. In this condition, total FLAVONOID and ANTHOCYANIN contents showed a similar trend and their contents were significantly reduced at 16 μM compared with the control. On the contrary, by increase in the elicitor concentration, the activity of ANTIOXIDANT ENZYMES specially catalase and superoxide dismutase, remarkably increased compared with the control, while total protein content drastically decreased. Based on the results, it is deduced that the increase in FNS I gene expression and total FLAVONOID and ANTHOCYANIN contents, were the results of oxidative stress following absorption of these elicitors and activation of plant antioxidant system.
