Biofilm Formation by the Fish Pathogen Flavobacterium columnare: Development and Parameters Affecting Surface Attachment
Flavobacterium columnare is a bacterial fish pathogen that affects many freshwater species worldwide. The natural reservoir of this pathogen is unknown, but its resilience in closed aquaculture sys...
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 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...
Development of LAMP and Real-Time PCR Methods for the Rapid Detection of Xylella fastidiosa for Quarantine and Field Applications
Xylella fastidiosa is a regulated plant pathogen in many parts of the world. To increase diagnostic capability of X. fastidiosa in the field, a loop-mediated isothermal amplification (LAMP) and rea...
Diffusible Signal Factor (DSF) Synthase RpfF of Xylella fastidiosa Is a Multifunction Protein Also Required for Response to DSF
Xylella fastidiosa, like related Xanthomonas species, employs an Rpf cell-cell communication system consisting of a diffusible signal factor (DSF) synthase, RpfF, and a DSF sensor, RpfC, to coordin...
DIVERSITY OF CICADOMORPHA (HEMIPTERA: AUCHENORRHYNCHA) IN CITRUS ORCHARDS IN NORTHEASTERN ARGENTINA
Among phytophagous insects, the Cicadomorpha are important economically because they damage crops by sucking plant sap and by transmitting plant pathogens, such as Spiroplasma citri and Xylella fas...
Drip-irrigated Pecan Seedlings Response to Irrigation Water Salinity
Salinity responses and salinity-related suppression of budbreak of drip-irrigated pecan [Carya ihinoinensis (Wangenh.) K. Koch] seedlings under different irrigation water salinity (ECIRR) levels we...
Effects of DNA Size on Transformation and Recombination Efficiencies in Xylella fastidiosa
Horizontally transferred DNA acquired through transformation and recombination has the potential to contribute to the diversity and evolution of naturally competent bacteria. However, many differen...
Enhanced Reliability and Accuracy for Field Deployable Bioforensic Detection and Discrimination of Xylella fastidiosa subsp pauca, Causal Agent of Citrus Variegated Chlorosis Using Razor Ex Technology and TaqMan Quantitative PCR
A reliable, accurate and rapid multigene-based assay combining real time quantitative PCR (qPCR) and a Razor Ex BioDetection System (Razor Ex) was validated for detection of Xylella fastidiosa subs...
Formation of Stylet Sheaths in aere (in air) from Eight Species of Phytophagous Hemipterans from Six Families (Suborders: Auchenorrhyncha and Sternorrhyncha)
Stylet sheath formation is a common feature among phytophagous hemipterans. These sheaths are considered essential to promote a successful feeding event. Stylet sheath compositions are largely unkn...
GENETIC VARIATION OF XYLELLA FASTIDIOSA ASSOCIATED WITH GRAPEVINES IN TWO MAJOR VITICULTURAL REGIONS IN THE UNITED STATES: CALIFORNIA AND TEXAS
Xylella fastidiosa (Xf) causes diseases in many agricultural, horticultural, and landscape crops, including Pierce's disease (PD) of grapevines. PD has been a serious problem in scattered table, wi...
Genome sequence of Xanthomonas fuscans subsp fuscans strain 4834-R reveals that flagellar motility is not a general feature of xanthomonads
Xanthomonads are plant-associated bacteria responsible for diseases on economically important crops. Xanthomonas fuscans subsp. fuscans (Xff) is one of the causal agents of common bacterial blight ...
