Transformation of plants using Agrabacterium rhizogenes may affect secondary metabolite production as well as morphological changes. In this study, T-DNA from Ri plasmid in A. rhizogenes carrying pRi15834-PRT35S-GUS was introduced into tobacco leaf segments to initiate development of transformed hairy roots. Plant regeneration from transgenic roots used MS medium, and plants regenerated fro...

Beneficial microorganisms are increasingly used in agriculture, but their efficacy often fails due to limited knowledge of their interactions with plants and other microorganisms present in rhizosphere. We studied spatio-temporal colonization dynamics of lettuce roots and rhizosphere by genetically modified Streptomyces spp. Five Streptomyces strains, strongly inhibiting in vitro the major soil...

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...

Agrobacterium rhizogenes causes hairy root disease in plants. The neoplastic roots produced by A. rhizogenes infection is characterized by high growth rate and genetic stability. These genetically transformed root cultures can produce higher levels of secondary metabolites or amounts comparable to that of intact plants. Hairy root cultures offer promise for production of valuable secondary meta...

Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...

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 ...
