Silymarin production by hairy root culture of Milk thistle (Silybum marianum L. Gaertn) was investigated using Agrobacterium rhizogenes AR15834. Hairy roots were induced by injection or inoculation of explants with A. rhizogenes. One month old hairy roots were dissected from the explants and grown in Murashing and Skoog (MS) liquid medium. Polymerase Chain Reaction (PCR) using the B gene and th...

Background and objectives: Hyoscyamus reticulatus contains two distinguished tropane alkaloids, hyoscyamineand scopolamine and both of the compounds possesspotential acute or chronic toxicity. In the present study, a simple and efficient transformation system was established for in vitro hairy roots induction in Hyoscyamus reticulatus. M...

Lattice henbane (Hyoscyamus reticulatus L.) is an herbaceous, biennial plant belonging to Solanaceae family. H. reticulatus hairy roots were established from two-week-old leaves infected by A7 strain of Agrobacterium rhizogenes on solid Murashige and Skoog (MS) medium. In this study, abiotic elicitors including; Sodium silicate (Na2SiO3) with different concentrations (0, 1, 5 and 7 mM) and silv...

Hairy root culture is an effective method to produce secondary metabolites. In fact, hairy roots are genetically and biologically stable and also they are able to produce metabolites without hormones. Chicory (Cichorium intybus L.) is one of the most important medicinal plants with valuable medicinal compounds. In this research, hairy roots were induced by different Agrobacterium rhizogenes str...

The roots and rhizomes of Valeriana (Valerianaofficinalis L.) are rich with valuable metabolites such as valerenic acid and valepotriates are used as mild sedatives. The aim of the present study was to investigatethe effect of four levels of calcium and potassium compounds (half, full, 2 and 4-fold) of normal Murashige and Skoog (MS) media including KI and CaCl2on ValerianaofficinalisL. hairy r...

Induced hairy roots by Agrobacterium rhizogenes are suitable organs for the production of secondary metabolites, due to the stability and high production of roots without phyhormones in a short time. Fenugreek (Trigonella foenum– graecum L.) is one of the most important medicinal plants with valuable medicinal compounds. For optimizing the hairy root induction of T. foenum-graecum L., six strai...

Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The ...

Hairy root induction in plants has affected by many factors including type, age of explant and bacterial strain. In the present study, the effects of bacterial strains (A4, C58, 15834 and GM), two concentrations (OD600= 0.5 and 1) and two explants (leaves and stems) in hairy root induction of C. blumei</...
