Effect of plant growth regulators on growth and biosynthesis of phenolic compounds in genetically transformed hairy roots of Panax ginseng C. A. Meyer

, : Effect of plant growth regulators on growth and biosynthesis of phenolic compounds in genetically transformed hairy roots of Panax ginseng C. A. Meyer. Biotechnology and Bioprocess Engineering 12(2): 86-91

In this study, morphological alterations, biomass growth, and secondary metabolite production of genetically transformed hairy roots of Panax ginseng C. A. Meyer, were evaluated after administration of plant growth regulators. The addition of benzylamino purine and kinetin to the culture media increased biomass formation and phenolic compound biosynthesis in the hairy roots. alpha-Naphthaleneacetic acid and indole-3-butyric acid inhibited hairy root growth, however, low concentrations of indole-3-acetic acid slightly increased hairy root growth. Low concentrations of 2,4-dichlorophenoxyacetic acid profoundly inhibited growth of hairy roots. The addition of plant growth regulators, such as auxin, did not increase total phenolic compounds in hairy roots that did not contain gibberellic acid and cytokinins. Callus formation was induced in cultures suspended in liquid medium amended with benzylamino purine and kinetin. Hairy roots regenerated from these calluses exhibited an active growth pattern with extensive lateral branching in non-amended medium, similar to the growth pattern of the original hairy roots.
