Dynamic flux cartography of hairy roots primary metabolism

Phytochemistry, 2007
A dynamic model for plant cell and hairy root primary metabolism is presented. The model includes nutrient uptake (Pi, sugars, nitrogen sources), the glycolysis and pentose phosphate pathways, the TCA cycle, amino acid biosynthesis, respiratory chain, biosynthesis of cell building blocks (structural hexoses, organic acids, lipids, and organic ...

Cryopreservation of Transformed (Hairy) Roots ofArtemisia annua

Cryobiology, 1996
The antimalarial drug artemisinin has been found in transformed (hairy) roots of Artemisia annua. A protocol was developed to preserve A. annua hairy roots in liquid nitrogen. Root tips were excised from 7-day-old cultures and held on solid White's medium for 24 h prior to cryoprotection.

Induction of hairy roots in Gmelina arborea Roxb. and production of verbascoside in hairy roots

Plant Science, 2005
Seedling 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 ...

Hairy Root Cultures for Secondary Metabolites Production

2010
Hairy roots (HRs) are differentiated cultures of transformed roots generated by the infection of wounded higher plants with Agrobacterium rhizogenes. This pathogen causes the HR disease leading to the neoplastic growth of roots that are characterized by high growth rate in hormone free media and genetic stability.

Hairy root transformation in alfalfa (Medicago sativa L.)

Theoretical and Applied Genetics, 1987
The widely cultivated forage legume alfalfa (Medicago sativa L.) was transformed with the agropine type Agrobacterium rhizogenes NCPPB 1855. Sterile root and callus cultures were derived from tumorous hairy roots which were easily obtained independent of the plant variety or genotype.

Production and secretion of a heterologous protein by turnip hairy roots with superiority over tobacco hairy roots

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 ...

Hairy roots induced by Agrobacterium rhizogenes and production of regenerative plants in hairy root cultures in maize

Science in China Series C: Life Sciences, 2006
Hairy roots of maize were induced by infecting 15-d calli with Agrobacterium rhizogenes. The hairy roots cultured in hormone-free media showed the vigorous growth and typical hairy root features. The regenerated plants were produced from hairy roots in MS media supplemented with 1.6 mg/L ZT and 0.4 mg/L NAA.

Large-Scale Production of Hairy Root

2004
Many products of interest are synthesized in organized tissues, but not formed in suspension or callus culture. Therefore, most attention has been focused on root cultures. The transgenic plant,"hairy root", has brought us to dramatic improvements in growth rate and high content of desirable products.

Polyacetylenes in Lobelia sessilifolia hairy roots

Phytochemistry, 1994
Lobelia sessilifolia hairy roots (six clones: A-1 ∼4, and J-1 and 2), induced by Agrobacterium rhizogenes ATCC 15834 and A. rhizogenes MAFF 03-01724, grew well and produced some polyacetylenes (lobetyol, lobetyolin and lobetyolinin) in various hormone-free media. J-1 clone, transformed with A.

Red Beet Hairy Root Cultures

2012
The invention of hairy root induction from various higher plants has ­provided a new set of hopes for using such organs in vitro as an alternative to cell cultures, chiefly because of their genetic stabilities that impart them high biochemical consistencies.
