- Genetic characterization of a Streptococcus mutans LraI family operon and role in virulenceT Kitten
Philips Institute of Oral and Craniofacial Molecular Biology, Virginia Commonwealth University, Richmond, Virginia 23298, USA
Infect Immun 68:4441-51. 2000..Virulence for endocarditis was restored by correction of the sloC mutation but not by provision of the sloC gene in trans, suggesting that virulence requires the expression of other genes in the sloC operon...
- Genetic evidence that the gacA gene encodes the cognate response regulator for the lemA sensor in Pseudomonas syringaeJ J Rich
Department of Plant Pathology, University of Wisconsin Madison 53706
J Bacteriol 176:7468-75. 1994..Southwestern (DNA-protein) analysis revealed that the lemA and gacA genes were required for the full expression of a DNA binding activity...
- A newly identified regulator is required for virulence and toxin production in Pseudomonas syringaeT Kitten
Department of Plant Pathology, University of Wisconsin Madison, 53706, USA
Mol Microbiol 28:917-29. 1998..Thus, salA appears to encode a novel regulator that activates the expression of at least two separate genetic subsets of the gacS/gacA regulon, one pathway leading to syringomycin production and the other resulting in plant disease...
- Characterization of Porphyromonas gingivalis insertion sequence-like element ISPg5J V Califano
Department of Periodontics, Virginia Commonwealth University, Richmond, Virginia 23298, USA
Infect Immun 68:5247-53. 2000..gingivalis strains, including clinical isolates, diversity among strains was apparent. This suggests that ISPg5 and other IS elements may contribute to strain diversity and can be used for strain fingerprinting...
- The genetic relatedness of Porphyromonas gingivalis clinical and laboratory strains assessed by analysis of insertion sequence (IS) element distributionJ V Califano
Virginia Commonwealth University, Department of Periodontics, Philips Institute of Oral and Craniofacial Molecular Biology, School of Dentistry, Richmond, Virginia 23298 0566, USA
J Periodontal Res 38:411-6. 2003..We sought to determine the distribution of seven IS elements from strain W83 among nine P. gingivalis laboratory strains and nine clinical isolates and to use these findings to determine strain relationships...
- Suppression of a sensor kinase-dependent phenotype in Pseudomonas syringae by ribosomal proteins L35 and L20T Kitten
Department of Plant Pathology, University of Wisconsin Madison 53706, USA
J Bacteriol 178:1548-55. 1996..It is unclear how alteration of ribosomal protein expression compensates in this instance for loss of a transcriptional activator, but a regulatory role for L20 and L35 apart from their function in the ribosome may be indicated...
