it is an increased interest in the therapeutic potential of cannabis sativa l. (marijuana) for treatment of multiple sclerosis and hiv neuropathy. because of limitation in cultivation of this plant, an efficient hairy root induction system for cannabis sativa l. was developed in the present study. agrobacterium rhizogenes mediated transformation performed by two different co-cultivation mediums...
background: plant cell cultivations are considered as an alternative to agricultural processes for producing valuable phytochemicals (secondary metabolites). the use of plant cell cultures has overcome several inconveniences for the production of secondary metabolites. objective: the essential oils isolated from roots of 24-month-old field grown valerian (valeriana sisymbriifolium) and hairy ro...
Agrobacterium rhizogenes infects plants to induce hairy roots. It is classified into four different types such as agropine, mannopine, cucumopine and mikimopine. A.rhizogenes K599, also known as NCPPB2659, is a representative strain of the cucumopine type. In this review, we discussed the functions of 11 genes on the T-DNA of Ri plasmid pRi2659 in K599. We summarized the infectivity of K599 on ...
An improved Agrobacterium rhizogenes-mediated genetic transformation of Withania somnifera (L.) Dunal was developed using the bacterial strain R1000 with leaf segment explants of in vitro raised plantlets. Out of the three strains used (R1000, MTCC 2364 and MTCC 532), the strain R1000 proved to be more efficient than others. Among the different conditions tested, the highest (93.3 %) transforma...
Agrobacterium rhizogenes and Agrobacterium tumefaciens are plant pathogenic bacteria capable of transferring DNA fragments [transfer DNA (T-DNA)] bearing functional genes into the host plant genome. This naturally occurring mechanism has been adapted by plant biotechnologists to develop genetically modified crops that today are grown on more than 10% of the world's arable land, although their u...
Plant derived chemicals are valuable sources for a variety of pharmaceuticals, flavors, dyes, fragrance, stimulants, poisons. Hairy roots are induced in susceptible plants by transformation with Agrobacterium rhizogenes. Here we summarize the recent work using a novel bioreactor, the mist reactor, for the culture of hairy roots from many plant species. This study is based on the development of ...
