Specificity patterns of Agrobacterium tumefaciens phages

Archiv f�r Mikrobiologie, 1970
Lysogeny 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.

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 ...

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 ...

Small Noncoding RNAs in Agrobacterium tumefaciens

2018
During 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.

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 ...

Transfection and transformation of Agrobacterium tumefaciens

Molecular and General Genetics MGG, 1978
The freeze thaw transfection procedure of Dityatkin et al. (1972) was adapted for the transfection and transformation of A. tumefaciens. Transfection of the strains B6S3 and B6-6 with DNA of the temperate phage PS8cc186 yielded a maximum frequency of 2 10(-7) transfectants per total recipient population.

A chemotaxis cluster from Agrobacterium tumefaciens

Gene, 1998
We report the DNA sequence of a 9.6-kb region of the Agrobacterium tumefaciens chromosome containing a putative 8-kb chemotaxis operon. The putative operon begins with orf1, whose predicted protein product shows strong sequence identity to methyl-accepting chemotaxis proteins (MCPs), followed by orf2, cheY1, cheA, cheR, cheB, cheY2, orf9, orf10. All of

NADH oxidase system of Agrobacterium tumefaciens

Archives of Biochemistry and Biophysics, 1966
Evidence for the presence and possible participation of a flavoprotein, coenzyme Q, and a cytochrome in the oxidation of NADH in the cell-free extracts of Agrobacterium tumefaciens was presented. Coenzyme Q10 was established as the homologue by several criteria.

The T-pilus of Agrobacterium tumefaciens

Trends in Microbiology, 2000
T-pilus biogenesis uses a conserved transmembrane nucleoprotein- and protein-transport apparatus for the transport of cyclic T-pilin subunits to the Agrobacterium cell surface. T-pilin subunits are processed from full-length VirB2 pro-pilin into a cyclized peptide, a rapid reaction that is Agrobacterium specific and can occur in the absence of Ti ...
