We have sequenced the complete genome of the plant pathogen Agrobacterium tumefaciens strain LBA4213, a derivative of the wild-type strain A. tumefaciens Ach5 and the ancestor of A. tumefaciens strain LBA4404 used in genetic engineering. The genome consists of a circular chromosome and a linear chromosome, as well as a megaplasmid and a tumor-inducing plasmid.

A combined genetic and physical map of the Agrobacterium tumefaciens A348 (derivative of C58) genome was constructed to address the discrepancy between initial single-chromosome genetic maps and more recent physical mapping data supporting the presence of two nonhomologous chromosomes. The combined map confirms the two-chromosome genomic structure and the correspondence of the initial genetic m...

Agrobacterium tumefaciens is a phytopathogenic bacterium that causes crown gall disease. The strain Ach5 was isolated from yarrow (Achillea ptarmica L.) and is the wild-type progenitor of other derived strains widely used for plant transformation. Here, we report the complete genome sequence of this bacterium.

The genus Agrobacterium is composed of several phytopathogenic species occurring worldwide in soils. One nontumorigenic species, Agrobacterium radiobacter, has occasionally been isolated from clinical specimens, but its pathogenic role in these cases has been difficult to ascertain since agrobacteria are usually isolated in association with other bacteria. We report the case of a central venous...

the research has been done for assessment of effects of different concentrations of indole-3-butyric acid (iba) on rhizogenesis of scions of c. phlomidis in 2010.  the research has been done on randomized complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. different characters such as number of root of each scion, length of root, length of ne...

agrobacterium tumefaciens is capable to transfer genes across kingdoms. it can genetically transform not only plant cells, but also many other bacterial, algal, fungal, animal and human cells. this depends on the interactions among a variety of both agrobacterium and host genes. inside the host cell, rad52 which is involved in dna repair is a key gene determining integration of t-dna by homolog...

The results presented in this work support the hypothesis that Agrobacterium-mediated transformation of sorghum is feasible, analogous to what has been demonstrated for other cereals such as rice, maize, barley and wheat. The four factors that we found most influenced transformation were: the sensitivity of immature sorghum embryos to Agrobacterium infection, the growth conditions of the donor ...

Particle bombardment and Agrobacterium-mediated transformation are two popular methods currently used for producing transgenic maize. Agrobacterium-mediated transformation is expected to produce transformants carrying fewer copies of the transgene and a more predictable pattern of integration. These putative advantages, however, tradeoff with transformation efficiency in maize when a standard b...
