Agrobacterium tumefaciens is a plant pathogenic bacterium that contains a plasmid (the tumour-inducing or Ti plasmid), part of which (the T-DNA) integrates into the host plant chromosomes (Box 1.7); it has been termed "nature's genetic engineer". For plant transformation, the tumour-inducing genes are removed to make a "disarmed" plasmid. Agrobacterium tumefaciens (á que recentemente se lle cambiou o nome a Rhizobium radiobacter) [2] [3] é unha especie bacteriana que causa a formación de tumores nunhas 140 especies de plantas eudicotiledóneas. Ten forma de bacilo, é gramnegativa e vive no solo. [1]

Agrobacterium tumefaciens is a plant pathogen capable of transferring a defined segment of DNA to a host plant, generating a gall tumor. Replacing the transferred tumor-inducing genes with exogenous DNA allows the introduction of any desired gene into the plant. Thus, A. tumefaciens has been critical for the development of modern plant genetics and agricultural biotechnology. Here we describe

The papers included in this book were integral to the current understanding of the interaction of Agrobacterium with its hosts, its development into a major player in the genetic engineering of plants, and the biological control of crown gall. Agrobacterium tumefaciens: From Plant Pathology to Biotechnology is divided into five sections. The Agrobacterium tumefaciens is a member of the family Rhizobiaceae. These bacteria are Gram-negative and grow aerobically, without forming endospores. The cells are rod-shaped and motile, having one to six peritrichous flagella. Cells are 0.6-1.0 m m by 1.5- 3.0 m m and may exist singly or in pairs. In culture on carbohydrate-containing media Abstract. More than eighty years ago now Smith and Townsend [141] published an article in which they presented evidence that the bacterium which is now called Agrobacterium tumefaciens is the causative agent of the widespread neoplastic plant disease crown gall (Fig. 1). Isolation and Identification of Agrobacterium tumefaciens from Carrots (Daucus carota L.) Agrobacterium tumefaciens is a plant pathogenic bacterium that is widely used as a vector for inserting foreign genes into a plant chromosome to produce a transgenic plant. This bacterium cause a disease namely crown gall in dicotyledonous plants. Agrobacterium tumefaciens adalah bakteri patogen pada tanaman yang banyak digunakan untuk memasukkan gen asing ke dalam sel tanaman untuk menghasilkan suatu tanaman transgenik. Bakteri ini dipopulerkan oleh Mary-Dell Chilton sejak tahun 1977 melalui penelitiannya.

roots. It controls the bacterium Agrobacterium tumefaciens , which causes crown gall infection in certain plants, by competing directly with A. tumefaciens for food and space. A. radiobacter strain K84 is the overwhelming winner in this competition because it releases a protein that inhibits the growth of A. tumefaciens .

The efficacies of Agrobacterium radiobacter K84 and K1026 in root colonization, crown gall control, and plasmid transfer were compared. Levels of root colonization by K84 and K1026 of Montclar and Nemaguard peach seedlings were similar during the 21 days of the experiment. Four strains of A. tumefaciens bv. 1 were used for soil inoculations in biological control experiments on GF677 and

Agrobacterium is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. Agrobacterium tumefaciens is the most commonly studied species in this genus. fAgrobacterium tumefaciens- or Agrobacterium rhizogenes-mediated transformation is to date the most commonly used method for obtaining transgenic plants. fThe tumorigenic host plant species for range A. tumefaciensinclude: Large number of dicots and some monocots and Gymnosperms. fAgrobacteria are naturally occurring, ubiquitous soil borne Like many woody plant species, walnut (Juglans regia) can be difficult to genetically transform and regenerate. However, somatic embryos have been used successfully for over two decades as a target tissue for transformation and regeneration of transgenic walnut plants.

![Figure][1] (With Ze-Chun Yuan) - Bacteria of the genus Agrobacterium are very useful and unusual plant pathogens. Through a rare inter-kingdom DNA transfer, the bacteria move some of their genes into their host's genome, thereby inducing the host cells to proliferate and produce opines, nutrients sources for the pathogen. type strian of A. tumefaciens (ATCC23308T). Supported by statistical analysis of the number of induced tumors in potato disc strain AtTp0120 from Tagetes patula was identifi ed as more virulent than the other isolates.

Reproducible detection of all the tested pathogens in a single reaction was only possible with multiplex PCR using mixtures of virulence-, or oncogene specific primers.

The complexity of Agrobacterium-plant interaction has been studied for several decades. Agrobacterium pathogenicity is largely attributed to its evolved capabilities of precise recognition and response to plant-derived chemical signals.
