RNA-INTERFERENCE AND CONTROL OF THE GLASSY-WINGED SHARPSHOOTER AND OTHER LEAFHOPPER VECTORS OF XYLELLA FASTIDIOSA Principal Investigator:
This report presents the progress obtained in the development and application of an RNA interference (RNAi) based system aimed to target genes of the vector of Xylella fastidiosa(Xf), the glassy-winged sharpshooter (GWSS; Homalodisca vitripennis). After demonstrating that RNAi induction in GWSS cells and insects is achievable, in the year 2008-2009 we started screening a large pool of candidate...
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 Plasmid Transformation Vectors
We screened over 1,000 random Tn5 Xylella fastidiosa (Xf) mutants in Chardonnay grapevines growing in the greenhouse in 2003. Approximately 10 of the mutants exhibited a hypervirulent phenotype, i.e. vines inoculated with these mutants developed symptoms sooner and died sooner than vines inoculated with the wild type Xf parental strain. The identity of the Tn5 insertion sites in these mutants w...
متن کاملENDOPHYTIC BACTERIA ASSOCIATED WITH SHARPSHOOTERS, INSECT VECTORS OF XYLELLA FASTIDIOSA SUBSP. PAUCA Principal Investigator:
Xylella fastidiosa (Xf) subsp. Pauca causes citrus variegated chlorosis (CVC) disease in Brazil, resulting in significant production losses in the citrus industry. Xf is mainly transmitted by three species of sharpshooters (Hemiptera: Cicadellidae) in Brazil; Dilobopterus costalimai (Young), Acrogonia citrina Marucci & Cavichioli and Oncometopia facialis (Signoret). We identified bacterial comm...
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 ...
