Background matching behaviour and pathogen acquisition: plant site preference does not predict the bacterial acquisition efficiency of vectors
Many insect-borne pathogens are heterogeneously distributed within their hosts: therefore, a vector's within-plant distribution may be a predictor of its exposure to pathogens. In this study, we se...
Characterization and Correlation of EPG Waveforms of Bactericera cockerelli (Hemiptera: Triozidae): Variability in Waveform Appearance in Relation to Applied Signal
The tomatoDpotato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), was recently shown to be a vector of " Candidatus Liberibacter solanacearum" (Lso), a phloem-limited bacterium that ...
Characterization and transcriptional analysis of an ECF sigma factor from Xanthomonas campestris pv. campestris
The genomic DNA segment encoding the rpoE gene and its flanking region was cloned from Xanthomonas campestris pv. campestris strain 11 (Xc11). The transcriptional start site of rpoE was located at ...
Characterization of a Diffusible Signaling Factor from Xylella fastidiosa
Cell-cell signaling in Xylella fastidiosa has been implicated in the coordination of traits enabling colonization in plant hosts as well as insect vectors. This cell density-dependent signaling has...
Characterization of N2O-producing Xanthomonas-like isolates from biofilters as Stenotrophomonas nitritireducens sp nov., Luteimonas mephitis gen. nov., sp nov and Pseudoxanthomonas broegbernensis gen. nov., sp nov.
A group of yellow-pigmented isolates from ammonia-supplied biofilters showed an unusual denitrification reaction. All strains reduced nitrite but not nitrate without production of nitrogen (N-2). T...
Characterization of Novel Virulent Broad-Host-Range Phages of Xylella fastidiosa and Xanthomonas
The xylem-limited bacterium Xylella fastidiosa is the causal agent of several plant diseases, most notably Pierce's disease of grape and citrus variegated chlorosis. We report the isolation and cha...
Characterization of regulatory pathways in Xylella fastidiosa: Genes and phenotypes controlled by algU
Many virulence genes in plant bacterial pathogens are coordinately regulated by "global" regulatory genes. Conducting DNA microarray analysis of bacterial mutants of such genes, compared with the w...
Characterization of Regulatory Pathways in Xylella fastidiosa: Genes and Phenotypes Controlled by gacA
The xylem-limited, insect-transmitted bacterium Xylella fastidiosa causes Pierce's disease in grapes through cell aggregation and vascular clogging. GacA controls various physiological processes an...
Characterization of the LysR-type transcriptional regulator YcjZ-like from Xylella fastidiosa overexpressed in Escherichia coli
The Xylella fastidiosa 9a5c strain is a xylem-limited phytopathogen that is the causal agent of citrus variegated chlorosis (CVC). This bacterium is able to form a biofilm and occlude the xylem ves...
Characterization of the TolB-Pal trans-envelope complex from Xylella fastidiosa reveals a dynamic and coordinated protein expression profile during the biofilm development process
The intriguing roles of the bacterial Tol-Pal trans-envelope protein complex range from maintenance of cell envelope integrity to potential participation in the process of cell division. In this st...
Characterization of the Xylella fastidiosa PD1671 Gene Encoding Degenerate c-di-GMP GGDEF/EAL Domains, and Its Role in the Development of Pierce's Disease
Xylella fastidiosa is an important phytopathogenic bacterium that causes many serious plant diseases including Pierce's disease of grapevines. X. fastidiosa is thought to induce disease by colonizi...
Characterization of Xylella fastidiosa popP gene required for pathogenicity
Xylella fastidiosa (Xf) possess a two component regulatory system (TCS) PopP-PopQ which differentially regulates genes in response to environmental stimuli. To elucidate the role of popP in the pat...
