چکیده [English] | ||
In this study, the effects of three levels of methyl jasmonate (MJ) concentration were studied on the hairy root cultures of Origanum vulgare. For this purpose, A. rhizogenes strain A13 was used to create stable transformed. In this regard, two co-cultivation media (MS and modified MS), two inoculation times (5 and 10 min) as well two concentrations of acetosyringone (0 and 100 µM) were attentively studied. Propagated hairy roots were treated with different concentrations of MJ (0.1, 0.2, and 0.5 µM). Sampling after 24 and 96 h of MJ application, the antioxidant enzymes activities were evaluated. Moreover, the gene expression level of OvDXR and OvTPS2, two important genes involved in the MEP pathway, were studied using real-time PCR technique. The highest transformation rate was observed in the explants cultured modified MS which were incubated in the bacterial suspension with acetosyringone for 10 minutes. The biomass of hairy root cultures was significantly decreased by MJ compared to control samples. In addition, the results indicated that the concentration of MJ, harvesting time, and their interactions significantly affected the activity of catalase, peroxidase, and SOD enzymes. The expression of OvDXR significantly increased after 24 h of treatment by 0.2 µM MJ, while in the same sample, the expression of OvTPS2 decreased noticeably. The expression of OvDXR and OvTPS2 genes was significantly increased by 0.5 µM MJ after 96 h. The application of MJ as an efficient elicitor in hairy root culture system of O. vulgare is suggested for the production of valuable metabolites. | ||
