Hairy root induction in plants is the result of the insertion of T-DNA from Agrobacterium rhizogenes into the plant genome. The present study was conducted to investigate the effect of bacterium strain and plant species type on hairy root induction in two endemic (Salvia eremophila and S. reuterana) and five non-endemic (S. macrosiphon, S. multicaulis, S. nemorosa, S. verticellata and S. viriga...

Using Agrobacterium rhizogenes due to create hairy roots is a useful method to product secondary metabolites in many medicinal plants. The transgenic hairy roots were induced from Peganum multisectum (Maxim) Bobrov a medicinally important species, by infecting leaf and stem explant with wild type Agrobacterium rhizogenes strain ATTCC 15834, which led to the induction of hairy roots from 19% of ...

background: purple coneflower (echinacea purpurea l.) is one of the most important medicinal plants. hairy root culture of echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites. objective: the present study investigates the effects of kno3, cacl2 and mgso4 concentrations on growth and the biosynthesis of cichoric acid in echinacea ...

Agrobacterium rhizogenes (pRi), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. In our study four bacterial strains AR15834, A4, 9435 and C318 and three explants types leaf, stems and roots, were examined. Hairy roots were induced from roots, stems and leaf explants. The highest transformation efficiency of 77% was achieved by usi...

Background: Biotechnologic methods are common for secondary metabolites production from the plants and other sources in pharmaceutical sciences. Hairy root cell lines as the biotechnologic method have been used for in vitro production of major plant metabolites. Objective: In this study, hairy roots of Hypericum Perforatum have been prepared using the seeds and bio transformed by bacteria. Fin...

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...

The (-)-hyoscyamine, atropine and scopolamine (hyoscine) are three valuable tropane alkaloids while scopolamine is the most important member of this group for the pharmaceutical industry due to its higher demand compared to hyoscyamine and atropine. Scopolamine is an anticholinergic reagent with several therapeutic applications. In the current study, the hairy roots culture of Daturametel was u...

agrobacterium rhizogenes causes hairy root disease in plants. these hairy roots are ge-netically stable and grow rapidly. transformed hairy roots of hyoscyamus muticus in-duced by the bacterium can produce tropane alkaloids in trace amounts of intact plant tissues. in this research, in order to compare growth and biosynthetic stability of hairy roots with wild type ones, leaf and nodal segments...
