Detection of siderophores in endophytic bacteria Methylobacterium spp. associated with Xylella fastidiosa subsp. pauca
The objective of this work was to study the production of siderophores by endophytic bacteria Methylobacterium spp., which occupy the same ecological niche as Xylella fastidiosa subsp. pauca (Xfp) in citrus plants. The siderophore production of Methylobacterium strains was tested according to chromeazurol agar assay test (CAS), Csáky test (hydroxamate-type) and Arnow test (catechol-type). In ad...
متن کاملMapping analysis of the Xylella fastidiosa genome.
A cosmid library was made of the 2.7 Mb genome of the Gram-negative plant pathogenic bacterium Xylella fastidiosa and analysed by hybridisation mapping. Clones taken from the library as well as genomic restriction fragments of rarely cutting enzymes were used as probes. The latter served as a backbone for ordering the initial map contigs and thus facilitated gap closure. Also, the co-linearity ...
متن کاملInteraction between Xylella Fastidiosa and Curtobacterium Flaccumfaciens
Xylella fastidiosa (Xf) is a fastidious gram-negative, xylem-limited bacterium that causes diseases in many crops of economic importance, such as grape (Pierce’s disease), almond, peach, coffee, plum and citrus. Xf can infect all known Citrus sinensis cultivars and causes Citrus variegated chlorosis (CVC). One major endophyte isolated from CVC-asymptomatic plants is the bacterium Curtobacterium...
متن کاملANALYSIS OF XYLELLA FASTIDIOSA TRANSPOSON MUTANTS AND DEVELOPMENT OF AN EN PLANTA XYLELLA FASTIDIOSA PLASMID VECTOR Project Leader: Cooperator:
We have developed an autonomously replicating Xylella fastidiosa (Xf)/E. coli plasmid that efficiently transforms Xf; unfortunately this plasmid was not stably maintained in Xf cells en planta or without antibiotic selection in vitro. Another plasmid, containing an Xf native plasmid, a Kan cassette and cloned in pUC18 was also constructed and shown to be unstable without antibiotic selection. 1...
متن کاملROLES OF XYLELLA FASTIDIOSA PROTEINS IN VIRULENCE Project Leader:
This work derives from a preliminary experiment by Civerolo and Bruening in which Chenopodium quinoa (Cq) was found to develop a localized chlorosis 24-48 hr after leaves were infiltrated with a suspension of live or heat-killed Xylella fastidiosa (Xf) cells. Excised electrophoresis gel regions were assayed for chlorosis-inducing activity, which was associated with a protein band with mobility ...
