Agrobacterium and plant genetic engineering [PDF]
Plant Molecular Biology, 1992 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).

[18] Genetic Analysis of Agrobacterium
1991Publisher Summary This chapter discusses the genetic analysis of Agrobacterium. Genetic infection by Agrobacterium species is the only verified example of natural genetic exchange between the prokaryotic and eukaryotic kingdoms. Infection of plants by Agrobacterium strains containing tumor-inducing (Ti) or root-inducing (Ri) plasmids result in ...

Carbohydrate Research, 1983
Abstract The exocellular polysaccharides of Agrobacterium tumefaciens and Agrobacterium radiobacter have been investigated by the techniques of methylation and Smith degradation-periodate oxidation. The structure of the A. tumefaciens polysaccharide has been found to consist of hexasaccharide repeating-units having d -glucose as the sole sugar

Exopolysaccharides of Agrobacterium tumefaciens
2018Agrobacterium exopolysaccharides play a major role in the life of the cell. Exopolysaccharides are required for bacterial growth as a biofilm and they protect the bacteria against environmental stresses. Five of the exopolysaccharides made by A. tumefaciens have been characterized extensively with respect to their structure, synthesis, regulation, and ...

Agrobacterium molecular genetics
1988The bacteria of the genus Agrobacterium are well known as gene vectors for plant cells. In this chapter I shall discuss the following items: (l)the growth properties of different Agrobacterium strains; (2) methods for the introduction of DNA into Agrobacterium ; (3) rescue of plasmids via cointegration ; (4) gene replacement.

The Agrobacterium Virulence System
1991The soil bacterium Agrobacterium tumefaciens causes the plant tumor crown gall at wound sites on dicotyledonous plants (Fig.1). During crown gall induction, agrobacteria transfer a segment of their tumor-inducing (Ti)-plasmid to plant cells at the wound sites.

Plant-Agrobacterium Interaction [PDF]
, 1986 The plant-Agrobacterium interaction is a well-studied example of cell to cell signaling. It is giving us important information about factors and processes which play a role in pathogenesis.

Exploitation of Agrobacterium tumefaciens
1992During invasion of wounded plants, soil agrobacteria transfer a defined segment of their Ti and Ri plasmids into the plants. The transferred DNA, termed T-DNA, is integrated into the plant nuclear genome. Genes encoded by Ti and Ri plasmid T-DNAs are expressed in plants and confer the synthesis of plant growth factors as well as sugar and amino acid ...
