Doty S, Yu M, Lundin J, Heath J, Nester E
J Bacteriol
. 1996 Feb;
178(4):961-70.
PMID: 8576069
The transmembrane sensor protein VirA activates VirG in response to high levels of acetosyringone (AS). In order to respond to low levels of AS, VirA requires the periplasmic sugar-binding protein...

Lee Y, Jin S, Sim W, Nester E
Proc Natl Acad Sci U S A
. 1995 Dec;
92(26):12245-9.
PMID: 8618878
The virulence (vir) genes of Agrobacterium tumefaciens are induced by low-molecular-weight phenolic compounds and monosaccharides through a two-component regulatory system consisting of the VirA and VirG proteins. However, it is...

Deng W, Pu X, Goodman R, Gordon M, Nester E
Mol Plant Microbe Interact
. 1995 Jul;
8(4):538-48.
PMID: 8589410
Agrobacterium tumefaciens supervirulent strain A281 induces a progressive necrotic response, rather than tumor formation, when inoculated on stems of several grape cultivars. The Ti plasmid, and specifically its T-DNA, is...

Pan S, Jin S, Boulton M, Hawes M, Gordon M, Nester E
Mol Microbiol
. 1995 Jul;
17(2):259-69.
PMID: 7494475
Mutagenesis of the vir region on the Ti plasmid of Agrobacterium tumefaciens revealed a new locus, virJ, that is induced by the plant-wound signal molecule, acetosyringone (AS). virJ lies between...

Deng W, Gordon M, Nester E
J Bacteriol
. 1995 May;
177(9):2554-9.
PMID: 7730290
Two novel insertion sequences, IS1312 and IS1313, were found in pTiBo542, the Ti plasmid of Agrobacterium tumefaciens strains Bo542 and A281. Nucleotide sequencing and Southern hybridization revealed that IS1312 and...

Fullner K, Stephens K, Nester E
Mol Gen Genet
. 1994 Dec;
245(6):704-15.
PMID: 7830718
The 11 gene products of the Agrobacterium tumefaciens virB operon, together with the VirD4 protein, are proposed to form a membrane complex which mediates the transfer of T-DNA to plant...

Charles T, Doty S, Nester E
Appl Environ Microbiol
. 1994 Nov;
60(11):4192-4.
PMID: 7993100
We have extended the technique of electroporation as a genetic tool for manipulating the Agrobacterium tumefaciens chromosome. We used this technique to introduce chromosomal DNA into recipient A. tumefaciens strains...

Roitsch T, Jin S, Nester E
FEBS Lett
. 1994 Jan;
338(2):127-32.
PMID: 8307169
Virulence genes of Agrobacterium tumefaciens are transcriptionally activated in response to phenolic compounds and certain sugars. The transcription activator VirG specifically binds to fragments containing the conserved vir box sequence...

Doty S, Chang M, Nester E
J Bacteriol
. 1993 Dec;
175(24):7880-6.
PMID: 8253677
Certain plant phenolic compounds and monosaccharides induce the transcription of virulence (vir) genes of Agrobacterium tumefaciens through the VirA-VirG two-component regulatory system. The product of the chromosomal virulence gene chvE...

Pan S, Charles T, Jin S, Wu Z, Nester E
Proc Natl Acad Sci U S A
. 1993 Nov;
90(21):9939-43.
PMID: 8234338
Plant signal molecules such as acetosyringone and certain monosaccharides induce the expression of Agrobacterium tumefaciens virulence (vir) genes, which are required for the processing, transfer, and possibly integration of a...
