The identification of genetic factors that enable Xylella fastidiosa to express Pierce’s disease symptoms is essential to the further development of several disease control strategies. One such control strategy is to use non-pathogenic derivatives of the Pierce’s disease pathogen itself to competitively exclude pathogenic strains in grapevines. We have made progress in the development of geneti...

Xylella fastidiosa has been recognized as a pathogen of landscape trees for over 25 years. Collectively, these diseases are referred to as bacterial leaf scorch (BLS). Arborists, property owners, and communities are now beginning to recognize BLS as a serious threat to the urban forest. Although advances in symptom awareness and diagnostic techniques have enabled arborists to diagnose BLS, ther...

The disease outbreak of Xylella fastidiosa subsp. pauca strain CoDiRO (Complesso del Disseccamento Rapido dell’Olivo) in Salento (Apulia, South Italy) associated with severe cases of olive quick decline syndrome may represent not just a new disease paradigm, but a challenge for policy formulation and science communication in plant pathology. Plant health management can be achieved by applying a...

Xylella fastidiosa is a xylem-limited bacterium that causes citrus variegated chlorosis disease in sweet orange. There is evidence that X. fastidiosa interacts with endophytic bacteria present in the xylem of sweet orange, and that these interactions, particularly with Methylobacterium mesophilicum, may affect disease progress. However, these interactions cannot be evaluated in detail until eff...

The bacterium Xylella fastidiosa is a plant pathogen with a history of economically damaging introductions of subspecies to regions where its other subspecies are native. Genetic evidence is presented demonstrating the introduction of two new taxa into Central America and their introgression into the native subspecies, X. fastidiosa subsp. fastidiosa. The data are from 10 genetic outliers detec...

The goal of this project is to develop a technology to block the vector transmission of Xylella fastidiosa to plants. The approach focuses on the disruption of X. fastidiosa-vector interactions, so that the transmission of X. fastidiosa from one plant to another is affected. Our work has demonstrated that this approach is feasible and that we can disrupt sharpshooter transmission of X. fastidio...

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 ...
