Bacterial diversity in potential cicadellids vectors of Xylella fastidiosa Wells et al. in coffee plants in Puerto Rico
Bacteria from head and body tissues of three potential insect vectors of Xylella fastidiosa (Xf), Apogonalia spp., Hortensia similis and Caribovia coffeacola, were isolated in periwinkle wilt (PW) ...
Breaking dogmas: the plant vascular pathogen Xanthomonas albilineans is able to invade non-vascular tissues despite its reduced genome
Xanthomonas albilineans, the causal agent of sugarcane leaf scald, is missing the Hrp type III secretion system that is used by many Gram-negative bacteria to colonize their host. Until now, this p...
Combination of Chromogenic Differential Medium and estA-Specific PCR for Isolation and Detection of Phytopathogenic Xanthomonas spp.
A xanthomonad differential medium (designated Xan-D medium) was developed, on which streaks and colonies of xanthomonads, including 13 species of the genus Xanthomonas, turned wet-shining yellow-gr...
Detection of Xylella fastidiosa from resistant and susceptible grapevine by tissue sectioning and membrane entrapment immunofluorescence
Immunofluorescence detection was performed by tissue sectioning and membrane entrapment of Xylella fastidiosa from the inoculated hybrid selection F8909-08 (Vitis rupestris A. de Serres x V. arizon...
Detection of Xylella fastidiosa in potential insect vectors by immunomagnetic separation and nested polymerase chain reaction
A sensitive and specific assay for detecting Xylella fastidiosa in potential insect vectors was developed. This assay involves immunomagnetic separation of the bacteria from the insect, followed by...
Differential Susceptibility of Prunus Germplasm (Subgenus Amygdalus) to a California Isolate of Xylella fastidiosa
Seedling peach (Prunus persica Batsch) and clonal peach-almond hybrids are popular rootstock choices for commercial almond growers in California. In this study, clonal replicates of peach and almon...
Endosphere microbiome comparison between symptomatic and asymptomatic roots of Brassica napus infected with Plasmodiophora brassicae
Clubroot caused by Plasmodiophora brassicae, is a severe disease of cruciferous crops that causes large hypertrophic galls in the roots. The plant microbiome is important for growth promotion and d...
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...
Evidences of Siderophores Synthesis by Grapevine Xylella fastidiosa, Causal Agent of Pierce's Disease, through Instrumental Approaches
Siderophore molecules from grapevine Xylella fastidiosa were investigated. Such metabolites sequester iron, an essential element, from the host, making them a potential factor of pathogenicty. In a...
Evolution of the response of segregating populations of plums and the association with microsatellite markers of leaf scald
The evolution of leaf scald (Xylella fastidiosa) resistance was evaluated in individuals of seven plum segregating populations, consisted of seedling progenies originating from crosses involving ni...
Identification of three potential insect vectors of Xylella fastidiosa in southern Italy
In order to identify potential vectors of Xylella fastidiosa in olive orchards in Puglia (southern Italy), Hemiptera insects were collected from October to December, 2013, in olive orchards with hi...
Interaction between endophytic bacteria from citrus plants and the phytopathogenic bacteria Xylella fastidiosa, causal agent of citrus-variegated chlorosis
To isolate endophytic bacteria and Xylella fastidiosa and also to evaluate whether the bacterial endophyte community contributes to citrus-variegated chlorosis (CVC) status in sweet orange (Citrus ...
