Characterization of an Agrobacterium tumefaciens lectin
Glycobiology, 1991An 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.

The Oncogenes of Agrobacterium Tumefaciens and Agrobacterium Rhizogenes
2008The 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.

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 ...

THE INDUCTION OF LEAF TUMORS BY AGROBACTERIUM TUMEFACIENS
American Journal of Botany, 1965Using 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 bacterium, not substances released into the bacterial ...

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 ...

THE QUANTITATIVE DETERMINATION OF THE INFECTIVITY OF AGROBACTERIUM TUMEFACIENS
American Journal of Botany, 1965A bioassay relating number of Agrobacterium tumefaciens cells in the inoculum quantitatively to the number of crown‐gall tumors initiated on primary pinto bean leaves is described. Variability in estimation of infectious titers by this assay is similar to that observed in comparable plant virus assays, most determinations showing standard errors of 20%

Specificity patterns of Agrobacterium tumefaciens phages
Archiv f�r Mikrobiologie, 1970Lysogeny was not detected in 10 strains of A. tumefaciens by plating techniques or ultra-violet induction. Fifteen phages were isolated from raw sewage against 13 cultures of A. tumefaciens and purified by single-plaque selections. No phage lysed all of the strains of A.

Small Noncoding RNAs in Agrobacterium tumefaciens
2018During the last decade, small noncoding RNAs (ncRNAs) have emerged as essential post-transcriptional regulators in bacteria. Nearly all important physiological and stress responses are modulated by ncRNA regulators, such as riboswitches, trans-acting small RNAs (sRNAs), and cis-antisense RNAs.

l-Sorbose metabolism in Agrobacterium tumefaciens
Antonie van Leeuwenhoek, 1976The 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 ...

Transformation of rice mediated by Agrobacterium tumefaciens
1997Agrobacterium 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
