Agrobacterium rhizogenes induces hairy root disease in plants. The neoplastic (cancerous) roots produced by A. rhizogenes infection, when cultured in hormone free medium, show high growth rate and genetic stability. These genetically transformed root cultures can produce levels of secondary metabolites comparable to that of intact plants.

Hairy roots ? a short cut to transgenic root nodules
Plant Cell Reports, 1989To facilitate molecular studies of symbiotic nitrogen fixation a procedure for rapid production of transgenic root nodules was established on the legumeLotus corniculatus (Bird'sfoot trefoil). Regeneration of transgenic plants is not required as transgenic nodules are formed onAgrobacterium rhizogenes incited roots inoculated withRhizobium.

Induction of Hairy Roots by Agrobacterium Rhizogenes and Growth of Hairy Roots In Vitro
2003The bacterial genus Agrobucterium includes two species of considerable interest to plant physiologists and pathologists alike. Infection by virulent strains of A. tumefaciens induces the formation of tumors and infection by A. rhizogenes the proliferation of roots in a wide range of dicotyledenous plants: crown-gall and hairy root diseases are not ...

Induction of hairy roots in Gmelina arborea Roxb. and production of verbascoside in hairy roots
Plant Science, 2005Seedling tissues of Gmelina arborea, a medicinally important tree species, were infected with wild type Agrobacterium rhizogenes strain ATTCC 15834, which led to the induction of hairy roots from 32% of the explants. Transgenic status of the roots was confirmed by PCR using rolB specific primers, and subsequently, by Southern analysis of the PCR ...

The role of auxin in hairy root induction
Molecular and General Genetics MGG, 1987We have investigated the relative role of auxin and of Agrobacterium rhizogenes T-DNA in the induction of hairy roots. By infecting carrot discs with suitably constructed bacterial strains containing different T-DNA complements, we have shown that both auxin and the presence of T-DNA in the carrot cells are required for root growth on the discs.

Chemicals from Roots, Hairy Roots, and Their Application
1999Plants produce thousands of different compounds through the secondary metabolism pathways. Since many of these products are obtained by direct extraction from plants that are cultivated in the field or some times even collected in their original habitat several factors can alter their yield.

Polyprenols in hairy roots of Coluria geoides
Biochemical Society Transactions, 2000Long-chain polyisoprenoid alcohols built from several up to more than 100 isoprenoid units are common constituents of all living organisms. They were found mostly in plants, bacteria, yeasts and mammalian cells. In vitro hairy root culture of Coluria geoides was obtained from plants transformed with Agrobacterium rhizogenes. Growth was optimal at 0.75%

Hairy Roots as a Source for Phytoremediation
2021“Phytoremediation,” application of green plants to process and regulate the waste materials in soil, water, and the air is an important part of the new field of ecological engineering. Phytoremediation has been addressed as among the promising and eco-friendly processes for the decontamination of several environmental pollutants.

Biotechnology Letters, 2013
A fully contained and efficient heterologous protein production system was designed using Brassica rapa rapa (turnip) hairy roots. Two expression cassettes containing a cauliflower mosaic virus (CaMV) 35S promoter with a duplicated enhancer region, an Arabidopsis thaliana sequence encoding a signal peptide and the CaMV polyadenylation signal were ...
