摘要: The induction of hairy roots in Arnica montana L. by Agrobacterium rhizogenes mediated system was established. frequency genetic transformation varied from 4.8 to 12% depended on method infection. cefotaxime at concentration 200 mg/l proved suppress effectively the growth A. after co-cultivation. Among three tested nutrient media: Murashige and Skoog (MS), Gamborg’s (B5) Schenk Hildebrandt (SH), MS medium superior for high biomass production transformed compared other culture media. After culturing 40 days fresh weight clone T4 increased 7.6 fold over non-transformed roots. transfer rol A, B C genes into genome confirmed PCR analysis. Established techniques efficiently provided generated a large number — an excellent studying gene function could be used secondary metabolites synthesized
