Agrobacterium rhizogenes (recently revised as rhizobium rhizogenes young et al, 2001) is a soil-borne gram-negative bacterium that induces hairy roots upon wounding and infection of monocot and eudicot plants. The biological control strain agrobacterium rhizogenes k84 is an effective agent in the control of agrobacterium pathogens, the causative agents of crown gall disease a number of factors are thought to play a role in the control process, including production of the specific agrocins 84 and 434, which differ in the spectra of pathogenic strains that they inhibit in vitro. Agrobacterium rhizogenes is the etiological agent for hairy-root disease (also known as root-mat disease) this bacterium induces the neoplastic growth of plant cells that differentiate to form “hairy roots.

The closely related species, agrobacterium rhizogenes, induces root tumors, and carries the distinct ri (root-inducing) plasmid although the taxonomy of agrobacterium is currently under revision it can be generalised that 3 biovars exist within the genus, agrobacterium tumefaciens, agrobacterium rhizogenes, and agrobacterium vitis. 2 agrobacterium rhizogenes-mediated transformation in medicinal plants 35 36 d roychowdhury et al fig 21 ri-transformed roots of tylophora indica showing pigmentation a white root (bar = 9 mm), b green root (bar = 9 mm), and c red root (bar = 9 mm.

Agrobacterium rhizogenes

A proposal was made in 2011 by the ‘subcommittee on the taxonomy of agrobacterium and rhizobium’ to retain the agrobacterium genus by only transferring the more distantly related species, a rhizogenes, to rhizobium. Abstract agrobacterium rhizogenes strain k599 (pri2659), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species, including numerous soybean (glycine max) cultivarsbecause agrobacterium-mediated transformation of soybean remains challenging and labor intensive, k599 appeared a suitable progenitor for new agrobacteria strains for plant. Agrobacterium rhizogenes mediated transformation can be a useful alternative rhizogenes rooting of cuttings from recalcitrant woody species have been improved in some tree species root initiation limits vegetative propagation as a rapid and direct route for introduction and expression of specific traits. By agrobacterium rhizogenes, have been extensively used for studying gene functions in root development, nutrient uptake, and resistance to diseases and soil-born pests such as nematodes (wubben et al 2009) compared with whole plant transformation, generation of transgenic hairy roots.

Understanding expression of agrobacterium rhizogenes proteins (galls) required for gene transfer to plants - 14 million dollars worth of agriculture per year in california and oregon alone facts about codon bias. Agrobacterium rhizogenes, a soil pathogen which elicits adventitious, genetically (ri t-dna) transformed roots this leads to the production of so-called “composite plants” comprising a. Agrobacterium tumefaciens and a rhizogenes are the causal agents of the plant diseases crown gall and hairy root, respectively diseases are caused by the presence of bacterial dna, the transferred dna (t-dna), within the plant cells. Virulent strains of a tumefaciens and a rhizogenes, when interacting with susceptible dicotyledonous plant cells, induce diseases known as crow gall and hairy roots, agrobacterium-mediated gene transfer to plant cells has been archived however, agrobacterium tumefaciens.

Agrobacterium rhizogenes is a gram-negative, rod-shaped (06-10 x 15-30 µm), aerobic, soil-borne bacteria that occurs singly or in pairs and is motile by 1-4 peritrichous flagella (1) culturing techniques require the optimal temperature for growth of 25-28c. An efficient protocol for hairy root induction in berberis aristata dc was established using two different strains of agrobacterium rhizogenes, mtcc 532 and 2364 from imtech (institute of microbial technology), chandigarh, india the strain 532 was more effective than strain 2364 in hairy root induction and in vitro grown callus (6111 ± 160 % transformation frequency) was found to be. Agrobacterium rhizogenes is a pathogenic bacteria that causes hairy root disease by transferring bacterial dna into the plant genome it is an essential tool for industry and research due to its capacity to produce genetically modified roots and whole organisms.
