Agrobacterium tumefaciens genetically transforms plant cells by transferring a copy of its T-DNA to the plant where it is integrated and stably maintained. In the presence of wounded plant cells this process is activated and mediated by the produc...

The host range determining virC operon of Agrobacterium tumefaciens is known to consist of two open reading frames designated virC1 and virC2. Earlier work that employed insertional mutations in virC1 and virC2 established the role of the virC2 co...

The complete nucleotide sequence of the virB locus, from the octopine Ti plasmid of Agrobacterium tumefaciens strain 15955, has been determined. In the large virB-operon (9600 nucleotides) we have identified eleven open reading frames, designated...

The Agrobacterium tumefaciens virB gene products are proposed to assemble into a transport system capable of exporting complexes of DNA and protein across the bacterial envelope en route to plant cells. Nonpolar null mutations were constructed in...

Shirasu, K.; Morel, P.; Kado, C.I., 1990: Characterization of the virB operon of an Agrobacterium tumefaciens Ti plasmid: nucleotide sequence and protein analysis. The virulence regulon of the Agrobacterium tumefaciens TiC58 plasmid is composed of six operons, virA, virB, virG, virC, virD and virE, which direct the transfer of T-DNA into plant cells. The 9.5 kbp virB operon is the largest of these operons an...

Conjugative transfer of DNA that occurs between bacteria also operates between bacteria and higher organisms. The transfer of DNA between Gram-negative bacteria requires initial contact by a sex pilus followed by DNA traversing four membranes (don...

By using the analog noroctopine, mutants of agrobacterium tumefaciens were isolated with altered regulation patterns for the Ti plasmid-borne octopine utilization genes. These could be divided into three classes: (i) strains with a constitutive le...
