Exopolysaccharides of Agrobacterium tumefaciens

2018
Agrobacterium 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 ...

Particulate Cytochrome c in Agrobacterium tumefaciens

Archives Internationales de Physiologie et de Biochimie, 1975
In Agrobacterium tumefaciens the main part of c-type cytochromes is tightly bound to the bacterial cell envelope structures. Several techniques were attempted to solubilize these cytochromes. The highest yield of cytochromes released is obtained by treatment of particle suspensions with 5% Triton X-100.

THE INDUCTION OF LEAF TUMORS BY AGROBACTERIUM TUMEFACIENS

American Journal of Botany, 1965
Using carborundum as an abrasive and light rubbing with a culture of Agrobacterium tumefaciens, leaves of various species of bean and tobacco develop tumors on the leaf lamina. The induction of these tumors requires wounding, the presence of a virulent strain of the bacterium and is due to ...

The Oncogenes of Agrobacterium Tumefaciens and Agrobacterium Rhizogenes

2008
The common soil bacteria Agrobacterium tumefaciens and Agrobacterium rhizogenes are unique genetic pathogens capable of fundamentally redirecting plant metabolism in order to generate macroscopic tissue masses (crown galls and hairy roots, respectively) which support the growth of large populations of Agrobacteria.

Transformation of rice mediated by Agrobacterium tumefaciens

Plant Molecular Biology, 1997
Agrobacterium tumefaciens has been routinely utilized in gene transfer to dicotyledonous plants, but monocotyledonous plants including important cereals were thought to be recalcitrant to this technology as they were outside the host range of crown gall. Various challenges to infect monocotyledons including rice with Agrobacterium had been made in many

Agrobacterium tumefaciens-Mediated Wheat Transformation

Cereal Research Communications, 2003
An efficient and reproducible Agrobacterium tumefaciens-mediated system for wheat transformation was developed and genetically transformed wheat plants were produced using precultured immature embryos as the expiant. The embryos were inoculated with a disarmed A.

Characterization of an Agrobacterium tumefaciens lectin

Glycobiology, 1991
An Agrobacterium tumefaciens suspension induces a strong agglutination of aldehyde-fixed pig erythrocytes at pH 5.0. The agglutination is inhibited by some polysaccharides, such as fucoidin, and also when the pH is raised to 7.0. Lectins (sugar-binding proteins) associated with the bacterial cell wall of A.

Exploitation of Agrobacterium tumefaciens

1992
During 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 ...

l-Sorbose metabolism in Agrobacterium tumefaciens

Antonie van Leeuwenhoek, 1976
The pathway of L-sorbose metabolism in Agrobacterium tumefaciens strain B6 was determined to be: L-sorbose leads to D-glucitol (sorbitol) leads to D-fructose leads to D-fructose-6-phosphate leads to D-glucose-6-phosphate. The reduction of L-sorbose and the oxidation of D-glucitol were mediated by NADPH- and NAD+-linked oxidoreductases, respectively ...
