Crop Vulnerability: Carya
Long-established native tree populations reflect local adaptations. Representation of diverse populations in accessible ex situ collections that link information on phenotypic expression to informa...
Detecting Genetic Introgression: High Levels of Intersubspecific Recombination Found in Xylella fastidiosa in Brazil
Documenting the role of novel mutation versus homologous recombination in bacterial evolution, and especially in the invasion of new hosts, is central to understanding the long-term dynamics of pat...
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...
Interactive effects of water stress and xylem-limited bacterial infection on the water relations of a host vine
Xylella fastidiosa, a xylem-limited bacterial pathogen that causes bacterial leaf scorch in its hosts, has a diverse and extensive host range among plant species worldwide. Previous work has shown ...
Large-Scale Intersubspecific Recombination in the Plant-Pathogenic Bacterium Xylella fastidiosa Is Associated with the Host Shift to Mulberry
Homologous recombination plays an important role in the structuring of genetic variation of many bacteria; however, its importance in adaptive evolution is not well established. We investigated the...
Molecular characteristics of a strain (Salento-1) of Xylella fastidiosa isolated in Apulia (Italy) from an olive plant with the quick decline syndrome
DNA-based approaches were used to characterize a strain (Salento-1) of Xylella fastidiosa obtained from an olive plant suffering from the syndrome of quick decline in Apulia (South Italy). Salento-...
New Coffee Plant-Infecting Xylella fastidiosa Variants Derived via Homologous Recombination
Xylella fastidiosa is a xylem-limited phytopathogenic bacterium endemic to the Americas that has recently emerged in Asia and Europe. Although this bacterium is classified as a quarantine organism ...
Population Genomic Analysis of a Bacterial Plant Pathogen: Novel Insight into the Origin of Pierce's Disease of Grapevine in the US
Invasive diseases present an increasing problem worldwide; however, genomic techniques are now available to investigate the timing and geographical origin of such introductions. We employed genomic...
Population Structure of the Bacterial Pathogen Xylella fastidiosa among Street Trees in Washington DC
Bacterial leaf scorch, associated with the bacterial pathogen Xylella fastidiosa, is a widely established and problematic disease of landscape ornamentals in Washington D.C. A multilocus sequence t...
Several subspecies and sequence types are associated with the emergence of Xylella fastidiosa in natural settings in France
Xylella fastidiosa is a plant pathogenic bacterium emerging in Europe. In France its emergence has been demonstrated through interceptions of contaminated coffee plants and, in 2015, by a survey of...
The Complex Biogeography of the Plant Pathogen Xylella fastidiosa: Genetic Evidence of Introductions and Subspecific Introgression in Central America
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 presen...
