Abstract: (668 Views) |
Atropa belladonna has positive medicinal values due to the presence of tropane alkaloids. In this study, 5 strains of Agrobacterium rhizogenes A4, ATCC, 1724, R1000, and MSU were used in three explants of leaves, stems, and roots to induce hairy roots. Finally, after selecting the superior line, it was exposed to six concentrations and five treatments of methyl jasmonate treatment. According to the results obtained, the type of explants and different strains of Agrobacterium rhizogenes succeeded in having a significant effect on the percentage of hairy root production, also among the three explants used in the culture medium; only the leaf explant produced hairy roots with the highest rate of rooting (45.5%) was achieved by inoculation with the R1000 strain. In general, the methyl jasmonate elicitor will cause stress and toxicity if the concentration and duration of exposure to this treatment increase, and damage and reduced growth will be observed in the roots. However, using it correctly at the right concentration and time will increase metabolic activities and act as a strong molecular messenger.
